An HTML5 breakpoint resuming method

Abstract

The invention discloses an HTML5 breakpoint resuming method. The method comprises the following steps that 1, an uploading file is selected through a browser file selection box; 2, whether the video unique identifier is successfully created by using the ajax request uploading server or not is judged, if yes, the step 3 is executed, and otherwise, the step 6 is executed; and step 3, the video unique identifier returned in the step 2 is sent to a server by using the ajax to obtain a video uploading position and the like. According to the invention, when the network shakes or the HTTP connectionis disconnected, the browser can continue to upload the video file from the disconnected position; The file uploading is faster; The breakpoint is continuously uploaded in the file uploading process,and the situation that the whole file is uploaded again after uploading fails due to the fact that the network speed is low and the file is jammed is avoided; The uploading time is shorter, and the file uploading is faster; The uploading process is interrupted due to low network speed or network jitter of the breakpoint continuous uploading video, the uploaded file part does not need to be uploaded again, and only the non-uploaded file part needs to be uploaded.

Description

technical field [0001] The invention relates to the field of a video cloud storage system applied to browsers to upload video files, in particular to a method for HTML5 breakpoint resume transmission. Background technique [0002] Traditional browsers upload video files, select files to create unique video identifiers, and send video files and unique video identifiers to the server through the HTTP protocol. During the entire upload process, the browser continuously sends video files to the server. When the entire video file and unique video identifiers All are sent to the server. After the server returns the uploaded information, the browser will prompt the user that the video file has been uploaded successfully. In the existing solution, the browser and the server continue to send the file stream. When there is jitter in the network, or other conditions cause the HTTP connection to be disconnected, the upload fails, and the upload cannot be continued. When the file is too ...

Problems solved by technology

In the existing solution, the browser and the server continue to send the file stream. When there is jitter in the network, or other circumstances cause the HTTP connection to be disconnected, the upload fails, and the upload cannot be continued. When the file is too large, the network is unstable and it is easy to appear Cases where the upload fails
