Problems solved by technology

Nowadays, there are many ways to upload based on the client mode, such as using various front-end upload components to upload files as a whole or upload files in pieces (blocks), even if some upload components that support fragments pay attention to the breakpoint itself, but continue The upload granularity is file stream (block), and most of them do not persist the breakpoint position, which not only wastes the file upload time and network resources, but also cannot guarantee the accuracy and stability of file resume

Embodiment

[0032] Such as figure 1 and figure 2 As shown, the file breakpoint resume transmission method of the present invention obtains breakpoint information based on the browser, and executes file stream resume transmission based on the breakpoint information. Specifically include the following steps:

[0033] S1. The user confirms that the browser and the network environment of the server are connected, and the browser initiates a file upload request and a file check request.

[0034] (1) When the browser initiates a file request, the file is uploaded to the server in the form of a file stream through the front-end upload component of the browser.

[0035] (2) When the browser initiates a file inspection request, the request includes the source file name, file size, file type, and file timestamp information of the source file. The server responds to the file inspection request, and the obtained file name, file size, file After the type and file timestamp information are combined...

Abstract

The invention discloses a file broken-point continuingly-transferring method, and belongs to the technical field of information resources. The file broken-point continuingly-transferring method of theinvention acquires broken-point information based on a client, and performs file stream continuingly-transferring based on broken-point information. The method specifically comprises following steps:step S1, initiating a file upload request and a file check request by the client; step S2, determining and saving a file broken-point location by a server; step S3, acquiring file broken-point information by the client; step 4, responding to a continuingly-transferring file stream request by the server; and step S5, receiving a file upload result identifier by the client. The file broken-point continuingly-transferring method provided by the invention can save the file upload time and network resources, can ensure the file continuingly-transferring accuracy and stability, and has good popularization and application value.

Description

technical field [0001] The invention relates to the technical field of information resources, and specifically provides a method for resuming a file from a broken point. Background technique [0002] Today's Internet technology is developing rapidly, and the site development and construction model based on B / S (Browser / Server), that is, client-side / server-side, is spread in every corner of the Internet world. The information acquisition and information publishing relying on the browser client also greatly facilitates the sharing and exchange of information resources. As an important carrier of information resources, files are often uploaded to the server in an Internet environment based on browser clients to facilitate downloading and sharing of file resources. However, it is inevitable to encounter network interruption or the failure of the transmission end to respond normally during file transfer, which requires retransmission of files. In order to deal with this situati...
