Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts correspond to the protection scope of the present invention.

[0057] An embodiment of the present invention provides a data transmission system, including a client and a background server, wherein the business client is used to obtain local file data to be transmitted; cache the local file data, and analyze the local file data Fragment processing: determine the feature identifier of each fragment data in the local file data, send the fragment data and the feature identifier to the background server, and record the tra...

Abstract

The embodiment of the invention provides a data transmission method, device and system. The method is applied to a client, and the client can be a browser with HTML5 function. Specifically, the data transmission method comprises the following steps: firstly acquiring to-be-transmitted local file data, and then caching the local file data to the client, performing fragment processing on the local file data, and determining a feature identifier of each fragment data in the local file data; and then sending the fragment data and the feature identifier to a background server, and recording the transmission process of the fragment data. Visibly, the data with large data size is uploaded in a blocking way, one feature identifier is determined for each fragment data, thereby avoiding the repeateduploading. Since the data is fragmented, the uploading time of the single fragment of data is short, the data fragments with different features are required to be retransmitted when the data transmission is failed in the data uploading process, and the whole uploading time of the data with large data size is shortened.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a data transmission method, device and system. Background technique [0002] At present, when a browser uploads a file with a large amount of data, it usually uses the Netscape plug-in application programming interface (NPAPI) in the browser to upload, or performs data transmission through a local download APP. [0003] And, NPAPI plug-in it comprises flash plug-in, but, the development trend of current browser is to give up supporting flash plug-in, therefore, how to make the browser that does not have flash plug-in have the ability of the file that transmits the larger amount of data, it is those skilled in the art A major technical problem that needs to be solved urgently. Contents of the invention [0004] In view of this, the embodiment of the present invention provides a data transmission method, which realizes the transmission of files with a la...
