It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow diagram of a file transmission method according to an embodiment of the present invention, where the present embodiment is applicable to a case where files in an intranet and an extranet cannot be synchronized, and the method may be executed by a file transmission apparatus according to an embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and is generally configured in a computer device, as shown in fig. 1, the method specifically includes the following steps:
s101, receiving a file uploading request sent by an external network node, wherein the uploading request carries a specified storage path, a storage path of a file to be uploaded in the external network node and node information of the external network node.
A node is a computer or other device connected to a network having an independent address and a function of transmitting or receiving data. The nodes may be workstations, clients, network users or personal computers, servers, printers and other network-connected devices. Each workstation, server, terminal device, network device, i.e. the device having its own unique network address, is a node. The whole network is composed of a plurality of nodes, and the plurality of nodes are connected by communication lines to form a certain geometrical relationship, namely a computer network topology.
The intranet nodes are nodes in the internal local area network, and the extranet nodes are nodes in the external network. Illustratively, in a specific embodiment of the present invention, the intranet lan is an internal network of an e-government system.
When the external network node has a file transmission requirement, the external network node sends a file uploading request to a gateway (such as a router), and the gateway external network node sends a file uploading request to be received.
In the embodiment of the invention, the file uploading request carries the specified storage path, the storage path of the file to be uploaded in the external network node and the node information of the external network node. The designated storage path is a path in which a file to be uploaded is to be stored in an intranet node, and the node information of the extranet node may be an ip address, an MAC address of the node, or a unique identification code for characterizing the node.
In the embodiment of the present invention, the file may be a text, a picture, a video, an audio, an executable file or a folder, and the like, and the type and format of the file are not limited in the embodiment of the present invention.
S102, verifying the external network nodes based on the node information of the external network nodes in the file uploading request.
Specifically, after receiving the file uploading request, the file uploading request is analyzed to obtain node information of the extranet node, the extranet node is verified according to the node information of the extranet node, and whether the extranet node is a legal node is verified.
S103, when the verification is passed, downloading the file to be uploaded from the external network node through the storage path of the file to be uploaded in the external network node.
Specifically, after receiving the file uploading request, the file uploading request is analyzed, and a storage path of the file to be uploaded in the extranet node is obtained. In the step of verifying the extranet node based on the node information of the extranet node in the file uploading request, if the verification is passed, the file to be uploaded is downloaded from the extranet node through the storage path of the file to be uploaded in the extranet node.
And S104, uploading the file to be uploaded to an appointed storage path in the intranet node.
In the embodiment of the invention, after the file uploading request is received, the file uploading request is analyzed, and the appointed storage path of the file to be uploaded is obtained. After the file to be uploaded is downloaded from the external network node, the file to be uploaded is uploaded to the internal network node under the appointed storage path.
When the file is modified (for example, the content, the attribute and the like of the file are changed) in any one of the internal network node and the external network node, the corresponding file in the other node can be correspondingly modified, so that the file synchronization of two file storage systems which are not communicated with each other in the network is realized, and the method can be applied to an internal and external network exchange scene of an electronic government system. Illustratively, when a certain file is modified in an extranet node, the file can be found according to the specified storage path of the file in an intranet node, and corresponding modification is carried out, so that the file synchronization of two file storage systems which are not communicated with each other in the network is realized.
According to the file transmission method provided by the embodiment of the invention, after a file uploading request sent by an external network node is received, the external network node is verified based on the node information of the external network node in the file uploading request, when the verification is passed, a file to be uploaded is downloaded from the external network node through a storage path of the file to be uploaded in the external network node, and the file to be uploaded is uploaded to a designated storage path in the internal network node. When the file is modified in any one of the internal network node and the external network node, the corresponding file in the other node can be correspondingly modified, and the file synchronization of two file storage systems which are not communicated with each other in the network is realized.
Example two
Fig. 2 is a schematic flow chart of a file transmission method according to a second embodiment of the present invention, which is detailed based on the first embodiment, as shown in fig. 2, the method includes:
s201, receiving a file uploading request sent by an external network node, wherein the uploading request carries a specified storage path, a storage path of a file to be uploaded in the external network node and node information of the external network node.
The intranet nodes are nodes in an internal local area network, and the extranet nodes are nodes in an external network. Illustratively, in a specific embodiment of the present invention, the intranet lan is an internal network of an e-government system.
With the enhancement of environmental awareness of people and the continuous upgrading of office mode requirements of various industries, the pace of modernization and informatization construction is accelerated, and paperless office work is gradually applied to an electronic government system by concepts. Electronic government refers to a brand new management mode for office work, management and public service provision for society by comprehensively applying modern information technology, network technology, office automation technology and the like in government activities.
S202, judging whether the external network node sending the file uploading request belongs to a pre-configured white list or not based on the node information.
For example, information such as current limit fusing, authentication authorization, black and white list, etc. may be configured in the gateway in advance. Wherein requests belonging to the white list may be considered legitimate requests.
When a file uploading request sent by an external network node is received, whether the external network node sending the file uploading request belongs to a pre-configured white list or not can be judged based on node information, if so, the file uploading request is allowed to pass, and otherwise, the file uploading request is prevented from passing. By the method, illegal or redundant requests can be filtered before the gateway and outside the system, the safety and stability of an internal system are ensured, meanwhile, black and white lists and the like of the external requests are dynamically configured in the gateway, configuration in the gateway is not needed at each time, only operation and maintenance personnel add configuration in a configuration center, and the configuration is not needed to be frequently modified by a network administrator, so that the network safety is transmitted to the operation and maintenance personnel from the network administrator, and the complex and fussy system configuration is converted into simple application configuration.
And S203, when the verification is passed, downloading the file to be uploaded from the external network node through the storage path of the file to be uploaded in the external network node.
Specifically, after receiving the file uploading request, the file uploading request is analyzed, and a storage path of the file to be uploaded in the extranet node is obtained. In the step of verifying the extranet node based on the node information of the extranet node in the file uploading request, if the verification is passed, the file to be uploaded is downloaded from the extranet node through the storage path of the file to be uploaded in the extranet node.
And S204, searching the matched original file from the intranet node according to the file information of the file to be uploaded.
In the embodiment of the invention, after downloading the file to be uploaded from the external network node, the gateway searches the matched original file from the internal network node according to the file information of the file to be uploaded in the file uploading request. The file information may be a file name, or an encoding representing a file content, and the embodiment of the present invention is not limited herein. In the embodiment of the present invention, if the file names or codes representing the contents of the files of the two files are the same, the two files are regarded as substantially the same file.
For example, in a Linux file system, a partition is mainly divided into two parts: a small part is used to save inode information (index) of the file, and the remaining large part is used to save block information. The default size of the inode is 128 bytes, which is used to record the authority (read, write and delete) of the file, the owner and the affiliation of the file, the size of the file, the state change time of the file, the last read time of the file, the last modification time of the file, and the block number of the file where the data is really stored, and each file needs to occupy one inode. The inode does not record file names, and the file names are recorded in the block of the directory where the files are located. Each file occupies an inode by itself, and the file contents are pointed to by the inode's records.
If the original file matched with the file to be uploaded is stored in the intranet node (namely the file to be uploaded and the original file are the same). And when the matched original file is searched from the intranet node according to the file information of the file to be uploaded, searching the file name of the original file in the block where the directory is located. If the original file needs to be accessed, the inode of the original file needs to be found by means of the file name of the original file, and the block where the file content is located can be successfully found.
And S205, when the original file matched with the file to be uploaded exists in the intranet node, generating a link file pointing to the original file.
In the embodiment of the invention, if the original file matched with the file to be uploaded is found in the intranet node, the fact that the file identical with the file to be uploaded already exists in the intranet node is indicated, at this time, only a link file pointing to the original file needs to be generated and uploaded to the intranet node for storage.
Illustratively, in some embodiments of the present invention, the step S205 may include the following sub-steps:
1. and acquiring a relative path of the original file in the intranet node.
In the embodiment of the invention, if the original file which is the same as the file to be uploaded already exists in the intranet node, the relative path of the original file in the intranet node is obtained. The relative path refers to the path relationship with other files (or folders) caused by the path of the file. An absolute path is a path where a file actually exists on a hard disk, and is counted from the beginning of a disk character, if a file is located below "C: \ Program Files \ Jiangmin", then this path is its absolute path. A relative path may be understood as a portion of an absolute path and is a portion that does not include a system drive letter.
2. And taking the relative path of the original file as the file content of the link file.
In the embodiment of the invention, after the relative path of the original file in the intranet node is obtained, the link file is generated, and the relative path of the original file in the intranet node is used as the file content of the link file. Illustratively, in the embodiment of the present invention, in order to be consistent with the format of the photo of the identification card to be uploaded, the link file is in a picture format (e.g.,. jpg), the link file can be edited by using a notepad, and the relative path of the original file in the intranet node is written into the link file. When the original file needs to be checked in the later period, the link file can be opened, the relative path in the link file is obtained, and the original file can be found and printed according to the relative path.
Since the relative path of the original file in the intranet node is stored in the link file, the original file can be found according to the relative path even if the absolute path of the original file in the intranet node changes.
3. And generating the file name of the link file according to a preset strategy.
And generating a file name of the link file according to a preset strategy while generating the link file. Specifically, in the embodiment of the present invention, the file name of the link file includes node information of an external node (i.e., a node that uploads the file), the CRC32 code of the original file, the link file identification code, and the time when the link file is generated. When the original file needs to be checked in the later period, the link file is firstly positioned through the file name, the link file is opened, the relative path in the link file is obtained, and the original file can be found and printed according to the relative path.
And S206, uploading the link file to an appointed storage path in the intranet node.
And uploading the generated link file to the intranet node under the designated storage path.
Compared with the original file, the storage space occupied by the link file is less than 100 bytes, the occupied storage resource is greatly reduced, and meanwhile, the corresponding original file can be found through the link file subsequently. When the same file as the original file is transmitted to the intranet node, a link file pointing to the original file is newly created according to the method. Therefore, for one file, only the original file during the first transmission needs to be saved, the expenditure of storage resources caused by repeated files is greatly reduced, and the storage cost is reduced.
For example, when a user transacts electronic business with an e-government system, the e-government system often requires the user to upload identity information (e.g., a photograph or scanned piece of an identity card) via an extranet node to verify the user's identity. Since the identity information uploaded for many times is the same, if the identity information is saved each time, the storage overhead of the government affair system is inevitably huge. By adopting the file transmission method provided by the embodiment of the invention, the expenditure of storage resources caused by repeatedly uploading the same identity information is greatly reduced, and the storage cost is reduced.
And S207, uploading the file to be uploaded to a designated storage path in the intranet node when the original file matched with the file to be uploaded does not exist in the intranet node.
In the embodiment of the invention, if the original file which is the same as the file to be uploaded does not exist in the intranet node, the file to be uploaded is uploaded to the designated storage path in the intranet node.
In some embodiments of the present invention, the designated storage path of the file to be uploaded is a relative path of the file to be uploaded in the first node. And when the file to be uploaded (or the link file) is uploaded, uploading the file to be uploaded to a designated storage path of the intranet node according to the relative path. In this way, even if the storage path of a certain node in the internal network changes, the file can still be found through the relative path because the file is stored under the relative path.
In some embodiments of the invention, the e-government system may record the creation time of the link file in order to record the occurrence time of the authentication.
According to the file transmission method provided by the embodiment of the invention, the file uploading request comprises the appointed storage path of the file to be uploaded, and when the link file is stored, the link file is stored under the appointed storage path of the internal node according to the appointed storage path. Therefore, when the link file is modified at any one of the internal node and the external node, the corresponding file in the other node can be correspondingly modified, and the file synchronization of two file storage systems which are not communicated with each other in the network is realized. Furthermore, the designated storage path of the file to be uploaded is a relative path of the file to be uploaded in the extranet node. In this way, even if the storage path of a file at a certain node in the intranet network changes, the file is stored under the relative path, so that the file can still be found through the relative path. In addition, when the original file matched with the file to be uploaded exists in the intranet node, a link file pointing to the original file is generated and uploaded, and the corresponding original file can be found through the link file. Compared with the original file, the storage resource occupied by the link file is greatly reduced, and only the original file during the first transmission needs to be stored for one file, so that the storage resource overhead caused by repeated files is greatly reduced, and the storage cost is reduced.
