Therefore, when monitoring the network request process, it is impossible to determine which classes correspond to the methods involved in the network request process. Therefore, it is necessary to Classes are traversed, resulting in low network monitoring efficiency.

针对现有网络监测效率低的技术问题，本申请实施例提供一种解决方案，基本思路是：通过确定网络请求过程使用的方法的类的元类，将元类的方法替换为预设的网络监测方法，这样应用程序在执行网络请求过程可利用预设的网络监测方法对网络请求过程进行网络监测，实现整个网络请求过程的网络监测。由于元类为类的类，包含所有网络请求过程使用的方法对应的所有类，因此该网络监测方式无需遍历网络请求过程使用的方法对应的所有类即可实现对应用程序进行网络监测，有助于提高网络监测效率。Aiming at the technical problem of low efficiency of existing network monitoring, the embodiment of the present application provides a solution. The basic idea is: by determining the metaclass of the class of the method used in the network request process, and replacing the method of the metaclass with a preset network The monitoring method, so that the application program can use the preset network monitoring method to monitor the network request process during the execution of the network request process, so as to realize the network monitoring of the entire network request process. Since the metaclass is a class, including all classes corresponding to the methods used in all network request processes, this network monitoring method can implement network monitoring on applications without traversing all classes corresponding to methods used in network request processes, which is helpful for To improve the efficiency of network monitoring.
以下结合附图，详细说明本申请各实施例提供的技术方案。The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
应注意到：相同的标号在下面的附图以及实施例中表示同一物体，因此，一旦某一物体在一个附图或实施例中被定义，则在随后的附图和实施例中不需要对其进行进一步讨论。It should be noted that the same reference numerals refer to the same object in the following figures and examples, so once an object is defined in one figure or example, it is not necessary to refer to the following figures and examples It is discussed further.
图1为本申请实施例提供的网络监测方法的流程示意图。如图1所示，该网络监测方法包括：FIG. 1 is a schematic flowchart of a network monitoring method provided by an embodiment of the present application. As shown in Figure 1, the network monitoring method includes:
101、确定应用程序在网络请求过程使用的方法。101. Determine a method used by the application in the network request process.
102、确定网络请求过程使用的方法对应的类。102. Determine a class corresponding to the method used in the network request process.

The preset network monitoring method calls back the method of the metaclass after performing network monitoring.
在本申请实施例中，应用程序是指为完成某项或多项特定工作的计算机程序，它运行在用户模式，可以和用户进行交互，具有可视的用户界面。在本申请实施例中，不限定应用程序的具体实现形态。例如，应用程序可为APP、网页、小程序等，但不限于此。In this embodiment of the present application, an application program refers to a computer program for completing one or more specific tasks, it runs in a user mode, can interact with a user, and has a visual user interface. In the embodiments of the present application, the specific implementation form of the application is not limited. For example, the application program may be an APP, a web page, an applet, etc., but is not limited thereto.
由于应用程序多是模块化的，各个模块是解耦的，相当于黑盒，因此，网络请求过程监测时无法确定网络请求过程涉及的方法对应哪些类，因此，需要对应用程序所有的类进行遍历，导致网络监测效率低。Since most applications are modular, each module is decoupled, which is equivalent to a black box. Therefore, when monitoring the network request process, it is impossible to determine which classes the methods involved in the network request process correspond to. Therefore, all classes of the application need to be checked. Traversal, resulting in low network monitoring efficiency.
在本申请实施例中，网络监测是指对网络请求过程进行监测，可对网络请求整个过程进行监测，也可对网络请求的某个过程进行监测。在本申请实施例中，不限定网络请求的具体过程。在一些实施例中，如图2所示，网络请求过程可包括：从请求队列取网络请求阶段、域名(Domain Name Server，DNS)解析阶段、建立连接阶段、连接建立后发送网络请求阶段以及接收网络请求的响应报文阶段等。其中，建立连接阶段包括：安全连接阶段，即安全验证通过后建立连接。In the embodiment of the present application, the network monitoring refers to monitoring the network request process, and may monitor the entire network request process, and may also monitor a certain process of the network request. In this embodiment of the present application, the specific process of the network request is not limited. In some embodiments, as shown in FIG. 2 , the network request process may include: a network request stage from the request queue, a domain name (Domain Name Server, DNS) resolution stage, a connection establishment stage, a network request sending stage after the connection is established, and a receiving The response message phase of the network request, etc. The connection establishment phase includes: a secure connection phase, that is, the connection is established after the security verification is passed.
网络请求过程，针对当前执行的网络请求阶段，需要调用该阶段对应的方法来执行该阶段涉及的网络过程。例如，调用从请求队列取网络请求对应的方法，执行从请求队列取网络请求的过程等等。因此，为了实现网络请求过程的监测，在步骤101中，可确定应用程序在网络请求过程中至少一个阶段对应需调用的方法(用于执行该阶段涉及的网络过程)。In the network request process, for the currently executed network request stage, the method corresponding to this stage needs to be called to execute the network process involved in this stage. For example, calling the method corresponding to fetching network requests from the request queue, executing the process of fetching network requests from the request queue, and so on. Therefore, in order to monitor the network request process, in
在本申请实施例中，不限定确定应用程序在网络请求过程使用的方法的具体实施方式。在一些实施例中，可由技术人员对应用程序进行梳理，得到应用程序在网络请求过程使用的方法。进一步，可由技术人员手动输入应用程序在网络请求过程使用的方法。对于计算设备，可确定技术人员输入的方法为应用程序在网络请求过程使用的方法。In the embodiments of the present application, the specific implementation of the method for determining the application program used in the network request process is not limited. In some embodiments, the technical personnel can sort out the application to obtain the method used by the application in the network request process. Further, the method used by the application in the network request process can be manually input by the technician. For computing devices, the method input by the technician may be determined to be the method used by the application during the network request process.
具体地，可提供人机交互界面。该交互界面设置有方法配置项，该方法配置项为技术人员提供网络请求过程使用的方法提供输入接口。技术人员可通过该方法配置项接口设置网络请求过程使用的方法。相应地，针对计算设备，可响应于针对网络请求过程对应的方法配置项的设置操作，确定设置操作关联的方法为应用程序在网络请求过程使用的方法。Specifically, a human-machine interface can be provided. The interactive interface is provided with a method configuration item, and the method configuration item provides an input interface for the technician to provide the method used in the network request process. Technicians can set the method used in the network request process through the method configuration item interface. Correspondingly, for the computing device, in response to the setting operation of the method configuration item corresponding to the network request process, it may be determined that the method associated with the setting operation is the method used by the application in the network request process.
在另一些实施例中，应用程序对应的方法分别对应有应用程序接口(ApplicationProgramming Interface，API)，应用程序通过调用方法的API使用对应的方法。对于API，应用程序的开发人员可预先设置API的描述信息。每个API的描述信息可描述该API的用途，如在哪个阶段使用等等。相应地，可根据预先设置的API的描述信息，确定应用程序在网络请求过程使用的方法。In other embodiments, the methods corresponding to the application programs respectively correspond to application programming interfaces (Application Programming Interface, API), and the application programs use the corresponding methods by calling the APIs of the methods. For the API, the developer of the application can preset the description information of the API. The description information of each API can describe the purpose of the API, such as at which stage it is used, and so on. Correspondingly, the method used by the application in the network request process can be determined according to the preset description information of the API.
可选地，可对API的描述信息进行语义分析，以确定API对应方法的用途；并确定用于网络请求过程的方法为应用程序在网络请求过程使用的方法。Optionally, semantic analysis can be performed on the description information of the API to determine the purpose of the corresponding method of the API; and the method used in the network request process is determined as the method used by the application in the network request process.
由于类(class)为在面向对象编程中是一种面向对象计算机编程语言的构造，描述了所创建的对象共同的属性和方法。因此，为了实现对网络请求过程的监测，在步骤102中，还可确定网络请求过程使用的方法对应的类。具体地，可根据预设的方法与类之间的对应关系，确定网络请求过程使用的方法对应的类。例如，可将网络请求过程使用的方法在预设的方法与类之间的对应关系中进行匹配，确定网络请求过程使用的方法匹配中的类，即为网络请求过程使用的方法对应的类。Since a class is an object-oriented computer programming language construct in object-oriented programming, it describes the common properties and methods of the created objects. Therefore, in order to monitor the network request process, in
考虑到元类(meta class)是类的类。普通的类(class)定义的是特定对象的行为，元类(meta class)定义的则是特定的类及其对象的行为，因此，在本申请实施例中，为了提高应用程序的网络监测效率，在步骤103中，可根据网络请求过程使用的方法对应的类，确定网络请求过程使用的方法对应的类的元类。Consider that a meta class is a class of classes. A common class (class) defines the behavior of a specific object, and a meta class (meta class) defines the behavior of a specific class and its objects. Therefore, in this embodiment of the present application, in order to improve the network monitoring efficiency of the application program , in
由于类的方法存储在元类中，类通过Isa指针即可找到所属的元类。因此，可通过获取网络请求过程使用的方法对应的类中的Isa指针找到所属的元类。对于Objective-C语言编写的应用程序，由于Objective-C是基于C语言加入面向对象特性和消息转发机制的动态语言，即函数调用变成了消息发送，在编译期不能知道要调用哪个函数。因此，Objective-C不仅需要一个编译器，还需要运行时(Runtime)系统动态的创建类和对象，进行消息发送和转发。其中，运行时机制可解决如何在运行时期找到调用方法。Since the methods of the class are stored in the metaclass, the class can find the metaclass to which it belongs through the Isa pointer. Therefore, the metaclass to which it belongs can be found by obtaining the Isa pointer in the class corresponding to the method used in the network request process. For applications written in Objective-C language, since Objective-C is a dynamic language based on C language with object-oriented features and message forwarding mechanisms, that is, function calls become message sending, and it is impossible to know which function to call at compile time. Therefore, Objective-C not only requires a compiler, but also requires the runtime system to dynamically create classes and objects for message sending and forwarding. Among them, the runtime mechanism addresses how to find the calling method at runtime.
基于此，步骤103的一种实施方式为：可利用运行时机制运行网络请求过程使用的方法对应的类，以获取网络请求过程使用的方法对应的类中的Isa指针指向的类；并确定Isa指针指向的类为网络请求过程使用的方法对应的类的元类。Based on this, an implementation of
在确定出网络请求过程使用的方法对应的类的元类之后，在步骤104中，可将元类的方法替换为预设的网络监测方法，以使应用程序执行网络请求过程利用预设的网络监测方法进行网络监测。其中，预设的网络监测方法进行网络监测后可回调元类的方法，保证原有网络请求过程的闭环。After the metaclass of the class corresponding to the method used in the network request process is determined, in
在本申请实施例中，通过确定网络请求过程使用的方法的类的元类，将元类的方法替换为预设的网络监测方法，这样应用程序在执行网络请求过程可利用预设的网络监测方法对网络请求过程进行网络监测，实现整个网络请求过程的网络监测。由于元类为类的类，包含所有网络请求过程使用的方法对应的所有类，因此该网络监测方式无需遍历网络请求过程使用的方法对应的所有类即可实现对应用程序进行网络监测，有助于提高网络监测效率。In the embodiment of the present application, by determining the metaclass of the class of the method used in the network request process, the method of the metaclass is replaced with a preset network monitoring method, so that the application program can use the preset network monitoring method when performing the network request process. The method performs network monitoring on the network request process, and realizes the network monitoring of the entire network request process. Since the metaclass is a class, including all classes corresponding to the methods used in all network request processes, this network monitoring method can implement network monitoring on applications without traversing all classes corresponding to methods used in network request processes, which is helpful for To improve the efficiency of network monitoring.
本实施例提供的网络监测方法，可在运行时动态地将代码切入到指定方法(即预设的网络监测方法)上，从而实现了面向切面编程(Aspect Oriented Programming，AOP)。The network monitoring method provided by this embodiment can dynamically switch code to a specified method (ie, a preset network monitoring method) at runtime, thereby realizing Aspect Oriented Programming (AOP).
在本申请实施例中，不限定将元类的方法替换为预设的网络监测方法的具体实施方式。在一些实施例中，如图3中步骤304所示，可利用钩子(HOOK)技术在应用程序中添加预设的网络监测方法。其中，图3中的步骤301-303的描述，可参见上述图1的相关内容，在此不再赘述。In the embodiments of the present application, the specific implementation of replacing the metaclass method with the preset network monitoring method is not limited. In some embodiments, as shown in
进一步，在步骤305中，可将预设的网络监测方法注册至元类中；并在步骤306中，通过方法交互(method swizzling)方法交换元类的方法和预设的网络监测方法的函数体，从而使预设的网络监测方法替换元类的方法。其中，预设的网络监测方法可在执行完网络监测后回调元类的方法，实现原有网络请求过程的闭环，即实现原有网络请求过程的正常运行。Further, in
在一些实施例中，可通过method swizzling方法交换元类的方法和预设的网络监测方法的函数体对应的IMP指针，从而交换元类的方法和所述预设的网络监测方法的函数体。In some embodiments, the IMP pointer corresponding to the function body of the metaclass method and the preset network monitoring method can be exchanged through the method swizzling method, thereby exchanging the metaclass method and the function body of the preset network monitoring method.
在将元类的方法替换为预设的网络监测方法之后，应用程序执行网络请求过程可利用预设的网络请求方法进行网络监测。在本申请实施例中，不限定预设的网络监测方法的具体实现方法。在一些实施例中，预设的网络监测方法可实现为获取网络请求过程中每个网络请求阶段的执行时间，则预设的网络监测方法可实现为获取各网络请求阶段的开始时间和结束时间等等。在另一些实施例中，针对网络请求响应阶段的网络监测方法可实现为获取网络请求的响应数据，并对响应数据进行安全性校验等等。After replacing the method of the metaclass with the preset network monitoring method, the application program may use the preset network request method to perform network monitoring during the network request process. In the embodiments of the present application, the specific implementation method of the preset network monitoring method is not limited. In some embodiments, the preset network monitoring method may be implemented to obtain the execution time of each network request stage in the network request process, and the preset network monitoring method may be implemented to obtain the start time and end time of each network request stage and many more.
