数据服务请求应答方法和数据服务协议栈Data service request response method and data service protocol stack

技术领域technical field

本发明涉及通信领域中业务运营支撑技术，具体地，涉及数据服务请求应答的方法及数据服务协议栈。 The present invention relates to a business operation support technology in the communication field, in particular to a data service request response method and a data service protocol stack. the

背景技术Background technique

目前很多大型企业，如通信、金融等行业的企业都已经开始实施SOA(Service-Oriented Architecture，面向服务架构)。SOA提供了一种构建IT组织的标准和方法，通过建立可组合、可重用的服务体系来减少IT业务冗余，并加快项目开发的进程，SOA体系能够使IT部门效率更高、开发周期更短、项目分发更快，在协助IT技术和业务整合方面有着较高的价值。 At present, many large enterprises, such as enterprises in communication and financial industries, have begun to implement SOA (Service-Oriented Architecture, Service-Oriented Architecture). SOA provides a standard and method for building an IT organization. By establishing a composable and reusable service system to reduce IT business redundancy and speed up the project development process, the SOA system can make the IT department more efficient and the development cycle shorter. Shorter and faster project distribution, it has a high value in assisting IT technology and business integration. the

SOA实施过程中的关键内容之一在于数据服务的实现，数据服务作为应用与数据解耦的技术，可实现软件的高内聚、松耦合，可以提高软件的复用度。 One of the key contents in the SOA implementation process is the realization of data services. As a technology for decoupling applications and data, data services can achieve high cohesion and loose coupling of software, and can improve software reusability. the

现有业界在数据服务的实现方面主要有EJB、CORBA、DCOM和Web Service等技术，其中比较流行的是Web Service。Web Service使用标准的、规范的XML描述接口，来描述与服务进行交互所需要的全部细节，包括消息格式、传输协议和服务位置；而在对外的接口中隐藏了服务实现的细节，仅提供一系列可执行的操作，该操作独立于软硬件平台和编写服务所用的编程语言。Web Service的体系结构主要基于服务注册中心、服务请求者(即服务请求方)和服务提供者(即服务提供方)三种角色之间的交互，如图1所示。 In the existing industry, there are mainly technologies such as EJB, CORBA, DCOM, and Web Service in the realization of data services, among which Web Service is more popular. Web Service uses a standard and standardized XML description interface to describe all the details needed to interact with the service, including message format, transmission protocol and service location; while the details of service implementation are hidden in the external interface, only providing a A series of executable operations that is independent of hardware and software platforms and the programming language used to write the service. The architecture of Web Service is mainly based on the interaction between the three roles of service registry, service requester (that is, service requester) and service provider (that is, service provider), as shown in Figure 1. the

三种角色的交互主要涉及发布、查找和绑定操作，服务提供者定义Web服务的服务描述并把它发布到服务注册中心，服务请求者使用查找操作从本地或服务注册中心检索服务描述，然后使用服务描述与服务提供者进行绑定并调用Web服务。 The interaction of the three roles mainly involves publishing, searching and binding operations. The service provider defines the service description of the Web service and publishes it to the service registry. The service requester uses the lookup operation to retrieve the service description from the local or service registry, and then Use the service description to bind with the service provider and invoke the Web service. the

申请号为201010616910.4的中国专利申请介绍了一种Web Service服务的管理方法和系统，包括：网络服务器获取客户端发送的用户身份认证请求；所述用户身份认证请求包括：用户数字证书和用户身份认证信息；所述网络服务器将其获取到的用户身份认证请求转发给认证中心，以便所述认证中心对所述网络服务器以及用户身份进行认证；当所述认证中心完成认证后，所述网络服务器接收所述认证中心返回的认证结果；根据所述认证结果，所述网络服务器为所述客户端提供网络服务。本专利申请能够提高Web Service的安全性，还能有效的解决验证数字证书的使用者和所有者是否是同一实体的问题。 The Chinese patent application with application number 201010616910.4 introduces a management method and system for Web Service services, including: the network server obtains the user identity authentication request sent by the client; the user identity authentication request includes: user digital certificate and user identity authentication information; the network server forwards the obtained user identity authentication request to the authentication center, so that the authentication center can authenticate the network server and the user identity; when the authentication center completes the authentication, the network server receives The authentication result returned by the authentication center; according to the authentication result, the network server provides network services for the client. This patent application can improve the security of Web Service, and can also effectively solve the problem of verifying whether the user and owner of the digital certificate are the same entity. the

申请号为200910167170.8的中国专利申请公开了一种提供数据服务的处理系统及方法，包括：在接收到用户的提供数据服务的业务请求后，在需要调用外部接口时，基于调用外部接口的位置将业务拆分为初始逻辑业务和后续逻辑业务；对初始逻辑业务进行处理，并向反向代理服务器返回分段响应处理结果；反向代理服务器根据分段响应结果的请求调用外部接口；在调用的外部接口返回响应结果后，将分段响应结果与调用外部接口返回的响应结果整合成提供给用户的数据服务结果；向用户返回数据服务结果。本专利申请可以避免前端逻辑被阻塞，使得前端服务能够连续处理新请求而不用浪费时间在等待外部服务请求的响应上。 The Chinese patent application with application number 200910167170.8 discloses a processing system and method for providing data services, including: after receiving a service request from a user for providing data services, when an external interface needs to be called, based on the location where the external interface is called, the The business is split into initial logical business and subsequent logical business; the initial logical business is processed, and the segmented response processing result is returned to the reverse proxy server; the reverse proxy server calls the external interface according to the request of the segmented response result; After the external interface returns the response result, the segmented response result and the response result returned by calling the external interface are integrated into the data service result provided to the user; the data service result is returned to the user. This patent application can prevent the front-end logic from being blocked, so that the front-end service can continuously process new requests without wasting time waiting for the response of external service requests. the

总体来说，上述现有方案虽然可以一定程度上解决Web Service数据服务的实现问题，但主要针对服务接口层面实现，并不能深入到数据服务的内部实现细节进行规范说明，使数据服务的内部实现不能得到充分的解耦和复用，导致数据服务的内部实现比较复杂，影响数据服务的实现效率。 Generally speaking, although the above-mentioned existing solutions can solve the implementation problem of Web Service data services to a certain extent, they are mainly aimed at the implementation of the service interface level, and cannot go deep into the internal implementation details of the data service for specification, so that the internal implementation of the data service Cannot be fully decoupled and reused, resulting in complex internal implementation of data services, affecting the efficiency of data services. the

The invention discloses a data service request response method and a data service protocol stack, which can better solve the above problems. In addition to realizing the decoupling of the application and data, it can also realize the decoupling of the internal implementation of the data service, so that the internal implementation details of the data service More simple, efficient, clear, flexible and scalable. the

如图2所示，本发明的数据服务协议栈共划分为六层，自上而下依次是连接层、模型映射层、表示层、会话层、服务层和接口层；本发明的数据服务协议栈共分为两部分：服务请求方部分和服务提供方部分，服务请求方部分自上而下由表示层、会话层、服务层和接口层组成，服务提供方 部分自上而下由连接层、模型映射层、表示层、会话层、服务层和接口层组成；其中，服务请求方部分与服务提供方部分中的表示层、会话层、服务层和接口层的结构和功能都相同。数据服务便是由数据源数据，经过数据服务协议栈中连接层到接口层的逐层封装而成。 As shown in Figure 2, the data service protocol stack of the present invention is divided into six layers altogether, is successively connection layer, model mapping layer, presentation layer, session layer, service layer and interface layer from top to bottom; Data service protocol of the present invention The stack is divided into two parts: the service requester part and the service provider part. The service requester part is composed of presentation layer, session layer, service layer and interface layer from top to bottom, and the service provider part is composed of connection layer from top to bottom. , model mapping layer, presentation layer, session layer, service layer and interface layer; among them, the structure and function of the presentation layer, session layer, service layer and interface layer in the service requester part and service provider part are the same. The data service is formed by encapsulating the data source data layer by layer from the connection layer to the interface layer in the data service protocol stack. the

1、连接层 1. Connection layer

连接层用来实现数据服务对各种数据源的连接，以及数据源数据的操作，从而获取数据服务所需要的数据源数据。 The connection layer is used to realize the connection of data services to various data sources and the operation of data source data, so as to obtain the data source data required by data services. the

连接层通过数据源连接技术，例如JDBC、ODBC、FTP和SOAP等来实现对各种数据源的连接，并从数据源(即数据库)取得数据源数据。连接层从数据源取得数据后，以比特流形式的数据格式存在，如图3所示。 The connection layer connects to various data sources through data source connection technologies, such as JDBC, ODBC, FTP, and SOAP, and obtains data from the data source (that is, the database). After the connection layer obtains data from the data source, it exists in a data format in the form of bit stream, as shown in Figure 3. the

2、模型映射层 2. Model mapping layer

模型映射层用来实现数据服务的数据模型与数据源数据模型的映射，将数据服务的数据模型的查询语句转换为可执行的数据源的数据模型的查询语句，以及将连接层的数据源数据转换为关系型数据。 The model mapping layer is used to realize the mapping between the data model of the data service and the data source data model, convert the query statement of the data service data model into the query statement of the executable data source data model, and convert the data source data of the connection layer Convert to relational data. the

模型映射层为表示层提供的数据服务的数据模型的查询语句接口，主要可以采用标准的SQL或者LSQL(LSQL为中国移动经营分析系统数据仓库逻辑查询语言CMCC-LSQL)来实现。其中，SQL无法屏蔽数据库和数据模型之间的差异，因此主要适用于速度要求较高，数据模型差异不大的应用场景；而LSQL主要适用于速度要求不高，数据模型差异较大的应用场景。 The query statement interface of the data model provided by the model mapping layer for the data service provided by the presentation layer can mainly be realized by standard SQL or LSQL (LSQL is the logic query language CMCC-LSQL for the data warehouse of China Mobile's business analysis system). Among them, SQL cannot shield the difference between the database and the data model, so it is mainly suitable for application scenarios with high speed requirements and little difference in data models; while LSQL is mainly suitable for application scenarios with low speed requirements and large differences in data models . the

LSQL的数据格式如图4所示。 The data format of LSQL is shown in Figure 4. the

SQL的数据格式如图5所示。 The data format of SQL is shown in Figure 5. the

如果是SQL，则直接提交给连接层执行，如果是LSQL，则需要经过模型映射后转换为可执行的物理SQL，再提交给连接层执行。连接层通过连接技术将SQL提交数据库执行，并将获取的数据源数据，返回给模型映射层，模型映射层为了方便表示层的数据表示，将数据源数据转换为关系型数据，关系型数据格式如图6所示。 If it is SQL, it is directly submitted to the connection layer for execution. If it is LSQL, it needs to be converted into executable physical SQL after model mapping, and then submitted to the connection layer for execution. The connection layer submits SQL to the database for execution through the connection technology, and returns the obtained data source data to the model mapping layer. The model mapping layer converts the data source data into relational data and relational data format in order to facilitate the data representation of the presentation layer. As shown in Figure 6. the

3、表示层 3. Presentation layer

表示层用来表示数据服务交互过程中的数据，实现将模型映射层中的 关系型数据表示为数据服务交互过程中所需要的数据格式。 The presentation layer is used to represent the data in the process of data service interaction, and realize the representation of relational data in the model mapping layer as the data format required in the process of data service interaction. the

数据表示方式主要包括：XML、CSV和二进制的方式，在不同的数据服务交互过程中，数据的表示方式可能不同，如：在“在线请求-同步响应”的数据服务交互方式中采用XML作为数据的表示方式；在“在线请求-异步响应”和“发布-订阅”交互方式中的数据服务控制信息采用XML，而应答的数据内容采用CSV数据表示方式；在对数据格式有特殊要求的需求场合，可以采用二进制流的数据表示方式。 Data representation methods mainly include: XML, CSV and binary methods. In different data service interaction processes, data representation methods may be different. For example, XML is used as data in the "online request-synchronous response" data service interaction method. In the "online request-asynchronous response" and "publish-subscribe" interaction mode, the data service control information adopts XML, and the data content of the response adopts CSV data representation; in the case of special requirements for data format , you can use binary stream data representation. the

XML的数据表示方式如图7所示，CSV的数据表示方式如图8所示。 The XML data representation method is shown in Figure 7, and the CSV data representation method is shown in Figure 8. the

二进制流数据表示方式主要是根据具体应用的需要或者用户的要求，生成相应文件类型的数据，如Excel文件类型的数据，如图9所示。 The representation of binary stream data is mainly based on the needs of specific applications or user requirements to generate data of the corresponding file type, such as the data of the Excel file type, as shown in Figure 9. the

4、会话层 4. Session layer

会话层是服务请求方与服务提供方进行交互会话的场所，会话层通过不同的交互方式来表示数据服务的交互过程。 The session layer is the place where the service requester and the service provider interact with each other. The session layer represents the interaction process of data services through different interaction methods. the

会话层的数据交互方式有“在线请求-同步响应方式”、“在线请求-异步响应方式”和“发布-订阅方式”。该三种交互方式(即会话协商方式)的选择主要由数据的服务提供方决定，服务提供方根据自身数据量、实时性要求等特点，在数据服务开发时确定采用何种数据交互方式。具体说明如下： The data interaction modes of the session layer include "online request-synchronous response mode", "online request-asynchronous response mode" and "publish-subscribe mode". The choice of the three interaction methods (that is, the session negotiation method) is mainly determined by the data service provider. The service provider determines which data interaction method to use when developing data services according to its own data volume and real-time requirements. The specific instructions are as follows:

(1)在线请求-同步响应方式 (1) Online request-synchronous response method

在线请求-同步响应方式是指服务请求方向服务提供方发送数据请求，并进入阻塞状态，等待服务提供方的响应数据返回。服务提供方在接收到数据请求后，进行一系列的业务处理获取响应数据，并将响应数据回复给服务请求方。服务请求方在接收到响应数据后，中止阻塞状态继续运行。具体在线请求-同步响应方式的数据交互流程如图10所示。 The online request-synchronous response method means that the service requester sends a data request to the service provider, enters a blocking state, and waits for the response data from the service provider to return. After receiving the data request, the service provider performs a series of business processes to obtain the response data, and replies the response data to the service requester. After receiving the response data, the service requester stops the blocking state and continues to run. The specific online request-synchronous response data interaction process is shown in Figure 10. the

该方式适用于响应速度比较快，且数据量比较小的场合。由于发送数据请求的服务请求方需要阻塞运行，因此如果响应的速度比较慢，会造成服务请求方长时间阻塞不能运行，很可能会影响到服务请求方应用的正常运行；同样，如果传输的数据量比较大，那么传输的过程中请求数据的服务也需要等待，造成等待时间过长。 This method is suitable for situations where the response speed is relatively fast and the amount of data is relatively small. Since the service requester sending the data request needs to block the operation, if the response speed is relatively slow, the service requester will be blocked for a long time and cannot run, which may affect the normal operation of the service requester application; similarly, if the transmitted data If the amount is relatively large, the service requesting data during the transmission process also needs to wait, resulting in too long a waiting time. the

(2)在线请求-异步响应方式 (2) Online request-asynchronous response mode

在线请求-异步响应方式是指服务请求方调用服务提供方的“准备数据方法”，向服务提供方发送数据请求。服务提供方在接收到数据请求后，返回请求成功标志、数据准备的预估处理时间、建议定期查询数据准备情况的时间间隔和数据的获取方式等消息。服务请求方在获得上述消息后可继续运行，不需要长时间处于阻塞状态。服务提供方在返回上述消息后进行一系列的业务处理以准备数据。服务请求方在数据准备的预估处理时间到达后，按照建议定期查询数据准备情况的时间间隔，服务请求方向服务提供方发送查询数据准备情况的请求。如果数据未准备完毕，服务提供方返回数据未准备完毕的消息，服务请求方则在建议的时间间隔后继续查询；如果数据准备完毕，服务提供方返回包含何时何地如何获取数据的消息。服务请求方即可以按照给定的时间到给定的地点(FTP或HTTP地址)在给定的有效期内自行决定何时使用给定的方式(FTP或HTTP协议)取得数据。具体在线请求-异步响应方式的数据交互流程如图11所示。 The online request-asynchronous response method means that the service requester calls the service provider's "preparation data method" and sends a data request to the service provider. After receiving the data request, the service provider will return messages such as the request success flag, the estimated processing time of data preparation, the recommended time interval for regularly querying the data preparation status, and the method of data acquisition. After receiving the above message, the service requester can continue to run without being blocked for a long time. After returning the above message, the service provider performs a series of business processes to prepare the data. After the estimated processing time of data preparation arrives, the service requester will periodically query the data preparation status according to the recommended time interval, and the service requester will send a request for querying the data preparation status to the service provider. If the data is not ready, the service provider will return a message that the data is not ready, and the service requester will continue to query after the suggested time interval; if the data is ready, the service provider will return a message containing when, where and how to obtain the data. The service requester can then go to a given location (FTP or HTTP address) at a given time and within a given validity period to decide when to use a given method (FTP or HTTP protocol) to obtain data. The specific online request-asynchronous response data interaction process is shown in Figure 11. the

该方式适用于被请求的数据量产生时间比较长，或者数据量较大的场合。因为采用异步方式，不需要长时间的等待与阻塞，服务请求方可以正常运行其它功能，仅需要在接到数据准备完毕的信号之后再处理请求的数据。 This method is suitable for occasions where the requested data volume takes a long time to generate or the data volume is large. Because of the asynchronous method, there is no need for long-term waiting and blocking, and the service requester can run other functions normally, and only needs to process the requested data after receiving the signal that the data is ready. the

(3)发布-订阅方式 (3) Publish-subscribe method

发布-订阅方式是指服务请求方向服务提供方的“注册方法”注册请求数据的要求和通知服务。服务提供方在接到服务请求方的注册消息后，返回请求成功的标志。服务请求方在获得上述注册消息后，可以继续运行而不需要长时间处于阻塞状态，服务提供方在返回上述注册消息后，进行一系列的业务处理以准备数据。当数据准备完毕，服务提供方调用服务请求方注册的通知服务，告知服务请求方数据准备情况和相关的获取信息。服务请求方回复成功或失败的标志，服务请求方即可以按照给定的时间到给定的地点(FTP或HTTP地址)在给定的有效期内自行决定何时使用给定的方式(FTP或HTTP协议)取得数据，从而实现数据的触发式交互。具体发布-订阅方式的交互流程如图12所示。 The publish-subscribe method refers to the request and notification service for the service requester to register the request data with the "registration method" of the service provider. After the service provider receives the registration message from the service requester, it returns a sign that the request is successful. After the service requester obtains the above registration message, it can continue to run without being blocked for a long time. After the service provider returns the above registration message, it performs a series of business processes to prepare data. When the data preparation is completed, the service provider calls the notification service registered by the service requester to inform the service requester of the data preparation status and related acquisition information. The service requester replies with a sign of success or failure, and the service requester can go to a given location (FTP or HTTP address) at a given time and decide when to use a given method (FTP or HTTP address) within a given validity period. Protocol) to obtain data, so as to realize the triggered interaction of data. The interaction process of the specific publish-subscribe mode is shown in Figure 12. the

该方式适用于触发性传输各种数据量的数据封装服务，由于发布-订阅方式本质上是异步响应方式，因此服务请求方不需要长时间的等待与阻塞，可以正常运行其它功能。 This method is suitable for data encapsulation services that trigger the transmission of various data volumes. Since the publish-subscribe method is essentially an asynchronous response method, the service requester does not need to wait and block for a long time, and can run other functions normally. the

5、服务层 5. Service layer

服务层主要通过服务实现技术对表示层的数据做进一步的封装，把数据内容的消息体封装到数据服务的报文体中，并实现具体的数据服务。 The service layer further encapsulates the data of the presentation layer mainly through the service implementation technology, encapsulates the message body of the data content into the message body of the data service, and realizes the specific data service. the

服务层数据服务的实现主要采用Web Service技术，其中Web Service的服务提供方可以通过SOAP或者REST架构来实现。基于SOAP实现的数据服务，主要将表示层的数据内容消息体封装到SOAP协议的Body中，而基于REST实现的数据服务，主要将消息体封装到HTTP协议的报文体中。下面主要介绍基于SOAP的实现方式： The implementation of service layer data services mainly adopts Web Service technology, and the service provider of Web Service can be realized through SOAP or REST architecture. The data service based on SOAP mainly encapsulates the data content message body of the presentation layer into the Body of the SOAP protocol, while the data service based on REST mainly encapsulates the message body into the message body of the HTTP protocol. The following mainly introduces the implementation method based on SOAP:

5.1请求消息体封装 5.1 Request message body encapsulation

将表示层请求数据内容的消息体封装成SOAP请求报文的数据格式如图13所示。 Figure 13 shows the data format of encapsulating the message body of the request data content of the presentation layer into a SOAP request message. the

5.2应答消息体封装 5.2 Response message body encapsulation

将表示层应答数据内容的消息体封装成SOAP应答报文的数据格式如图14所示。 Figure 14 shows the data format of encapsulating the message body of the response data content of the presentation layer into a SOAP response message. the

6、接口层 6. Interface layer

接口层是在服务层的基础上，实现对数据服务消息头的安全、版本、路由和控制信息等的进一步封装，并将数据服务对外发布，提供给服务请求方调用，同时通过ESB(Enterprise Service Bus，即企业服务总线)技术来控制数据服务的访问，实现数据服务的集成和统一控制。 On the basis of the service layer, the interface layer realizes the further encapsulation of the security, version, routing and control information of the data service message header, and releases the data service to the outside world for the service requester to call. Bus, that is, enterprise service bus) technology to control the access of data services, and realize the integration and unified control of data services. the

基于SOAP实现的数据服务，主要将消息头封装到SOAP协议的Header中；而基于REST实现的数据服务，主要将消息头封装到HTTP协议报文头的自定义变量HeaderReq中。下面主要介绍基于SOAP的实现方式： The data service based on SOAP mainly encapsulates the message header into the Header of the SOAP protocol; while the data service based on REST mainly encapsulates the message header into the custom variable HeaderReq of the HTTP protocol header. The following mainly introduces the implementation method based on SOAP:

6.1请求消息头封装 6.1 Request header encapsulation

6.1.1服务版本 6.1.1 Service version

服务版本用于控制服务请求方对不同版本的数据服务的访问。在服务 层SOAP请求报文的基础上，封装了服务版本消息头的请求报文数据格式如图15所示。 Service versions are used to control the service requester's access to different versions of data services. On the basis of the service layer SOAP request message, the data format of the request message encapsulating the service version message header is shown in Figure 15. the

6.1.2服务路由 6.1.2 Service Routing

服务路由是将服务请求方的请求按照一定的路由规则发送到相应的服务提供方，主要应用于服务提供方进行分地区、分库等集群部署的情况。例如：可以根据地区的路由信息，将服务请求发送到该地区所在的数据服务服务器。 Service routing is to send the request of the service requester to the corresponding service provider according to certain routing rules. It is mainly used in the case where the service provider performs cluster deployment such as sub-regions and sub-databases. For example: according to the routing information of the region, the service request can be sent to the data service server where the region is located. the

在服务层SOAP请求报文的基础上，封装了服务路由消息头的请求报文数据格式如图16所示。 On the basis of the service layer SOAP request message, the data format of the request message encapsulating the service routing message header is shown in Figure 16. the

6.1.3请求时间 6.1.3 Request Time

请求时间用来标识本次数据服务访问的时间，作为访问日志的主要内容，方便日后的日志追踪排查。 The request time is used to identify the time of this data service access, as the main content of the access log, which is convenient for future log tracking and troubleshooting. the

在服务层SOAP请求报文的基础上，封装了请求时间消息头的请求报文数据格式如图17所示。 Based on the SOAP request message at the service layer, the data format of the request message encapsulating the request time header is shown in Figure 17. the

6.1.4认证鉴权 6.1.4 Authentication authentication

认证鉴权用来对服务请求方是否合法进行鉴别和确认。通过认证鉴权，可以使服务提供方确认服务请求方的身份，确定是否有该服务的访问权限。认证鉴权主要有以下两种方式： Authentication is used to identify and confirm whether the service requester is legitimate. Through authentication and authentication, the service provider can confirm the identity of the service requester and determine whether it has access to the service. There are two main methods of authentication:

(1)短连接认证 (1) Short connection authentication

短连接认证方式主要适用于外部系统对数据服务的访问，外部系统对数据服务的访问效率一般不会太高，但安全性相对较高，因此服务请求方每次请求时都要提供用户名、密码等校验信息来进行认证鉴权。 The short connection authentication method is mainly applicable to the access of external systems to data services. The access efficiency of external systems to data services is generally not too high, but the security is relatively high. Therefore, the service requester must provide the user name, Password and other verification information for authentication and authentication. the

在服务层SOAP请求报文的基础上，封装了短连接认证信息的请求报文数据格式如图18所示。 On the basis of the service layer SOAP request message, the data format of the request message encapsulating the short connection authentication information is shown in Figure 18. the

(2)长连接认证 (2) Long connection authentication

长连接认证方式主要适用于系统内部应用对数据服务的访问，内部应用对数据服务的访问效率一般会比较高，安全性也比较可靠，因此服务请求方只需在首次访问服务提供方的用户认证服务时，提供用户名、密码认证信息，经过认证通过后，服务提供方为服务请求方生成唯一的令牌信息， 服务请求方在令牌的有效期内，无需每次请求都提供用户名、密码等校验信息。 The persistent connection authentication method is mainly applicable to the access of data services by internal applications of the system. The access efficiency of internal applications to data services is generally higher and the security is more reliable. Therefore, the service requester only needs to authenticate the user when accessing the service provider for the first time. When serving, provide user name and password authentication information. After passing the authentication, the service provider generates unique token information for the service requester. The service requester does not need to provide the user name and password for each request within the validity period of the token. Wait for verification information. the

在服务层SOAP请求报文的基础上，封装了长连接认证信息的请求报文数据格式如图19所示。 Based on the SOAP request message at the service layer, the data format of the request message encapsulating the persistent connection authentication information is shown in Figure 19. the

6.1.5可靠请求源 6.1.5 Reliable request source

可靠请求源用来控制某个请求来源是否需要安全校验功能，对于受信任的系统，允许用户不经过安全校验，就能访问数据服务，可以减少受信任系统的开发工作。 The reliable request source is used to control whether a certain request source needs the security verification function. For a trusted system, users are allowed to access data services without passing the security verification, which can reduce the development work of the trusted system. the

在服务层SOAP请求报文的基础上，封装了可靠请求源信息的请求报文数据格式如图20所示。 Based on the SOAP request message at the service layer, the data format of the request message encapsulating reliable request source information is shown in Figure 20. the

6.1.6数字签名 6.1.6 Digital signature

数字签名是基于非对称加密技术的安全机制，通过数字签名技术可以保障数据或业务流量信息的机密性，以及预防客户端的抵赖行为。 Digital signature is a security mechanism based on asymmetric encryption technology. Digital signature technology can ensure the confidentiality of data or business flow information and prevent client denial. the

对SOAP请求报文进行数字签名后的数据格式如图21所示。 Figure 21 shows the data format after digitally signing the SOAP request message. the

6.2应答消息头封装 6.2 Response header encapsulation

应答消息头中主要封装了数据服务的应答时间、应答结果、应答错误编码、应答错误信息等控制信息内容，作为服务请求方对应答成功或者失败的判断依据，以及失败原因的分析。 The response message header mainly encapsulates the response time, response result, response error code, response error information and other control information content of the data service, which is used as the basis for the service requester to judge the success or failure of the response and analyze the cause of the failure. the

在服务层SOAP应答报文的基础上，封装了控制信息的应答报文数据格式如图22所示。 Based on the SOAP response message at the service layer, the data format of the response message that encapsulates the control information is shown in Figure 22. the

步骤126：服务提供方通过数据服务协议栈的连接层，将SQL语句通 过JDBC连接技术，提交到数据库中执行，自数据库中获取服务数据(即数据源数据)。 Step 126: The service provider submits the SQL statement to the database for execution through the connection layer of the data service protocol stack through the JDBC connection technology, and obtains the service data (that is, the data source data) from the database. the

服务应答流程 Service response process

服务提供方对“关键指标监控”应用发起的服务请求进行服务应答时，数据服务协议进行数据包的封装及解析的流程，如图29所示。 When the service provider responds to the service request initiated by the "key indicator monitoring" application, the data service protocol encapsulates and parses the data packet, as shown in Figure 29. the

具体流程步骤如下： The specific process steps are as follows:

步骤202：服务提供方通过数据服务协议栈的连接层，自数据库中获取到服务数据(即数据源数据)，数据源数据格式如图30所示。 Step 202: The service provider obtains service data (that is, data source data) from the database through the connection layer of the data service protocol stack. The format of the data source data is shown in FIG. 30 . the

步骤204：服务提供方通过数据服务协议栈的模型映射层，将数据源数据转换为关系型数据，方便数据服务协议栈的表示层的封装，转换后的关系型数据如图31所示。 Step 204: The service provider converts the data source data into relational data through the model mapping layer of the data service protocol stack to facilitate the encapsulation of the presentation layer of the data service protocol stack.
