Problems solved by technology

In the traditional way of transferring files, when the network is unstable, the transfer of large files often fails, and retransmission will waste traffic and transfer time
Moreover, due to the lack of communication between the public security intranet and the Internet, the files cannot be synchronized to the public security internal system in real time, resulting in untimely data circulation

Embodiment 1

[0034] see figure 1 with figure 2 , the present embodiment provides a cross-network resume method, including the following steps:

[0035] S1. The front end first encrypts the file to be uploaded, obtains the unique identifier of the file, and sends the unique identifier of the file to the backend;

[0036] S2. The backend queries the database according to the unique identifier of the file. If the file has been uploaded, it has reached the instant transmission, and can query the file name, size, storage location, file type and other file information, and directly return these file information to the front end; If it has not been uploaded, execute step S3;

[0037]S3. The front-end begins to fragment the uploaded file according to the custom configuration. The specific fragmentation method is: through dynamic monitoring of the network speed and bandwidth of the front-end, combined with the fragment size limit and the number of fragments in the custom configuration, to Dynam...

Embodiment 2

[0048] see figure 1 with figure 2 , this embodiment provides a cross-network breakpoint resume transmission system, including a front end and a back end, the front end is used to encrypt the file to be uploaded, obtain the unique identifier of the file, and send the unique identifier of the file to the back end; The backend queries the persistent library according to the unique identifier of the file. If the file has been uploaded, it directly returns the file information to the frontend, that is, the instant transmission is achieved; the frontend is used to start sharding the uploaded file according to the custom configuration, and after sharding Obtain a collection containing fragmented files and fragmented file information; fragmented file information includes the total number of fragments, the order of each fragmented file, the unique identifier of each fragmented file, and the file name, size, and file type of the original file , the unique identifier of the original fi...

Embodiment 3

[0052] see figure 2 with image 3 , the present embodiment provides a cross-network breakpoint resume transmission system, including a file encryption module, a file fragmentation module, a file upload control module, a file assembly module, a file forwarding module, and a file persistence module; wherein:

[0053] The file encryption module is used to encrypt the file to be uploaded to obtain the unique identifier of the file;

[0054] The file fragmentation module is used to fragment the file to be uploaded according to the custom configuration, and provides the fragmented file to the file upload control module;

[0055] The file upload control module is used to upload the fragmented files, and display the upload progress according to the returned results of the fragments, and re-upload the fragments that failed to upload;

[0056] The file forwarding module is used to forward the upload request of the file upload control module, and realize cross-network through reverse ...

Abstract

The present invention relates to a cross-network breakpoint resume transmission method and system. The front end encrypts the file to be uploaded, obtains the unique identifier of the file and sends it to the back end; the back end queries the database according to the unique identifier of the file, and returns the file directly if the file has been uploaded The information is sent to the front end; the front end starts to fragment the uploaded file according to the custom configuration, and obtains the fragmented file; the front end uploads the fragmented file to the backend, and displays the upload progress. If the fragment upload fails, re-upload the failed fragment ;The backend receives the fragmented files uploaded by the frontend, and performs unique identification verification. If the verification fails, it returns the upload file failure information to the frontend. If the verification is successful, it verifies whether all fragments have been uploaded. When all fragments are uploaded, Combine files according to fragmentation sorting, save the complete file in the file server, return the complete file information to the front end, and save the complete file information in the database. It can save time, traffic, and storage space.

Description

technical field [0001] The invention relates to the field of computer file transmission, in particular to a cross-network breakpoint resume transmission method and system. Background technique [0002] With the development of modern society, mobile office is becoming more and more frequent, and it is more and more convenient to use mobile phones for data collection. In the process of law enforcement, the police can use the portable mobile phone to record video, audio, and take pictures. In the traditional way of transferring files, when the network is unstable, the transfer of large files often fails, and retransmission will waste traffic and transfer time. Moreover, due to the lack of communication between the public security intranet and the Internet, the files cannot be synchronized to the public security internal system in real time, resulting in untimely data circulation. Contents of the invention [0003] The purpose of the present invention is to overcome the defe...
