Method and system for uploading files

Abstract

The invention relates to a method and a system for uploading files. The method includes that a user selects files to be uploaded and submits hashed value of the files to be uploaded. A request for file uploading and based on HTTPOST is sent to a server. File type of the files to be uploaded is judged, the next step is conducted on yes judgment, and failure warning is returned to the user to finish uploading on no judgment. The method further includes recognizing content of the files to the uploaded, reminding the user that identical files exist, returning pre-existing file address and finishing uploading if identical files exist in the server, starting uploading if no identical files exist in the server, calculating the hashed value of the uploaded files, comparing the hashed value with submitted hashed value, reminding that file uploading succeeds, returning the file address to the user and finishing uploading if the values are identical, and returning the uploading failure warning and finishing uploading if the values are not identical. The method and the system resolve the problems of synonym file re-uploading, file type judgment, file verification and the like.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and system for uploading files based on http post. Background technique [0002] With the widespread application of Internet technology, users' demand for file transfer is also increasing day by day. The hypertext transfer protocol Http defines the communication method of file transfer between the server and the client. Compared with the ftp protocol used in the past, the http protocol is more suitable for web programming in terms of file transfer technology, and has better security and simpler permission control. Httpclient is an efficient, up-to-date, feature-rich client programming toolkit that supports the http protocol. It implements methods including GET, POST, PUT, HEAD, etc., where the POST method is used to send a request to the destination server. It can be used to upload files. [0003] In the prior art, there are the following disadvantages in th...

AI Technical Summary

Problems solved by technology

[0004] 1. When uploading files, there is no file verification, so the integrity and reliability of uploaded files cannot be guaranteed, nor can normal file functions be guaranteed;

[0005] 3. When the upload fails, when uploading again, it does not support resuming the upload

[0006] 2. There is no automatic file identification function, that is, the existing system cannot automatically identify the file type

[0007] 4. The existing system does not have the function of breaking up storage, that is, it does not have the ability to automatically adapt to the corresponding storage directory according to the file type. Therefore, after the file is uploaded successfully in the existing system, the file corresponds to the same domain name. For example, a user needs to access a web page with three image elements: jpg, png, and gif. The existing file upload system accesses these three types of image elements through the same domain name. When the page loads, all elements need to be queued for loading. Pages load slowly
