Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. 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 this embodiment is applicable to a situation where the same file is repeatedly transmitted multiple times and the overhead of storage resources is relatively large, 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, a file uploading request of a first node is obtained, wherein the file uploading request comprises file information of a file to be uploaded.

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.

When the first node has a file transmission requirement, the first node sends a file uploading request to the second node, and the second node receives the file uploading request. In this embodiment of the present invention, the first node may directly communicate with the second node, and the first node may also indirectly communicate with the second node through an intermediate communication device (for example, a router).

In this embodiment of the present invention, the file upload request includes file information of a file to be uploaded, where the file information may be a file name or an encoding representing a content of the file, and this 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.

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, searching for the matched original file from the second node according to the file information of the file to be uploaded in the file uploading request.

In the embodiment of the invention, after receiving the file uploading request, the second node analyzes the file uploading request, and analyzes the file information of the file to be uploaded from the file uploading request. And then, searching the matched original file from the second node according to the file information of the file to be uploaded in the file uploading request.

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 second node stores the original file matched with the file to be uploaded (namely the file to be uploaded and the original file are the same). And when the matched original file is searched from the second node according to the file information of the file to be uploaded in the file uploading request, 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.

S103, when an original file matched with the file to be uploaded exists in the second node, a link file pointing to the original file is generated.

In the embodiment of the present invention, if the original file matched with the file to be uploaded is found in the second node, it is indicated that the file identical to the file to be uploaded already exists in the second node, at this time, only the link file pointing to the original file needs to be generated in the second node and stored. 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 second node, a link file pointing to the original file is created again 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.

The file transmission method provided by the embodiment of the invention obtains the file uploading request of the first node, the file uploading request comprises the file information of the file to be uploaded, the matched original file is searched from the second node according to the file information of the file to be uploaded in the file uploading request, when the original file matched with the file to be uploaded exists in the second node, the link file pointing to the original file is generated, and the corresponding original file is 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.

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, and the scheme of the second embodiment of the present invention is described in detail with reference to an e-government system, as shown in fig. 2, the method includes:

s201, a file uploading request of the first node is obtained, wherein the file uploading request comprises file information of a file to be uploaded.

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.

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 identification card) 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.

In the embodiment of the invention, the nodes in the electronic government affairs system network are called internal nodes, and the nodes outside the electronic government affairs system network are called external nodes. The first node is an external node and the second node is an internal node.

When the external node has a file transmission requirement, the external node sends a file uploading request to the internal node, and the internal node receives the file uploading request. In an embodiment of the present invention, the external node may also indirectly communicate with the internal node through an intermediate communication device (e.g., a gateway, a router, etc.). In general, a gateway or a router does not intercept information sent out by an internal node, but identifies and screens information from an external node that wants to enter an internal network, and forwards the information to the internal node after the information is considered to be safe and effective.

In the embodiment of the present invention, the invention is described by taking the type of the transmitted document as a picture (an id card photograph or a scanned article). Generally, when a government affairs system requires a user to upload an identification card photo, the user is required to input the name and the identification number of the user at the same time, and the name and the identification number of the user can be recognized from the uploaded picture through Optical Character Recognition (OCR). The file uploading request comprises the name, the identification number and the like of the user. Of course, in other embodiments of the present invention, the file information may include the CRC32 code for the file.

In some embodiments of the present invention, the e-government system employs a distributed storage method, where the distributed storage is a data storage technology, and uses disk space on each machine in the enterprise through a network, and forms a virtual storage device with these distributed storage resources, and the data is stored in various nodes of the internal network in a distributed manner.

S202, searching for the matched original file from the second node according to the file information of the file to be uploaded in the file uploading request.

Since the identity information of each user is unique, the matched original file can be searched from the internal node through the identity information of the user.

S203, judging whether an original file matched with the file to be uploaded exists in the second node.

Specifically, if the return value of the search result is 0, it is determined that the original file matched with the file to be uploaded is not found in the internal node, that is, the same id card photo as the id card photo to be uploaded does not exist in the internal node, and at this time, step S204 is executed.

If the return value of the search result is 1, it is considered that the original file matched with the file to be uploaded is searched in the internal node, that is, the internal node already has the same id card photo as the id card photo to be uploaded, and at this time, steps S205-S208 are executed.

And S204, storing the file to be uploaded to the second node.

In the embodiment of the invention, if the identity card photo identical to the identity card photo to be uploaded does not exist in the internal node, the file to be uploaded is stored in the internal node.

In some embodiments of the present invention, the file upload request sent by the external node further includes a specified storage path of the file to be uploaded, and when the file to be uploaded is stored, the file to be uploaded is stored under the specified storage path of the internal node according to the specified storage path. Therefore, when the 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, 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 the internal and external network exchange scene of the e-government system.

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. 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. And when the file to be uploaded is stored, storing the file to be uploaded under the appointed storage path of the internal node according to the relative path. In this way, even if a path change occurs in a certain node in the internal network, since the file is stored under the relative path, the file can still be found through the relative path.

S205, acquiring a relative path of the original file in the second node.

In the embodiment of the invention, if the identity card photo identical to the identity card photo to be uploaded already exists in the internal node, the relative path of the original file in the second node is obtained.

S206, taking the relative path of the original file as the file content of the link file.

In the embodiment of the present invention, after the relative path of the original file in the second node is obtained, the link file is generated, and the relative path of the original file in the second 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 second 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.

S207, 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.

Since the relative path of the original file in the internal 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 internal node changes.

And S208, recording the creation time of the link file.

In the embodiment 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.

S209, storing the link file in the designated storage path.

In the embodiment of the present invention, the file upload request further includes a specified storage path of the file to be uploaded, and when the link file is stored, the link file is stored in the specified storage path of the internal node according to the specified 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, 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 the internal and external network exchange scene of the e-government system.

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 link file is stored, storing the file to be uploaded under the corresponding relative path in the internal node according to the relative path of the file to be uploaded in the first node. In this way, even if a path change occurs in a certain node in the internal network, since the file is stored under the relative path, the file can still be found through the relative path.

According to the file transmission method provided by the embodiment of the invention, when the original file matched with the file to be uploaded exists in the internal node, the link file pointing to the original file is generated, and the corresponding original file is 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. The file uploading request also comprises an 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. Further, the designated storage path of the file to be uploaded is a relative path of the file to be uploaded in the first node. In this way, even if a path change occurs in a certain node in the internal network, since the file is stored under the relative path, the file can still be found through the relative path.
