Abstract

The invention relates to the technical field of networks, in particular to a method for processing uploading of multiple-instance large files based on a browser. The method for processing uploading of the multiple-instance large files based on the browser is characterized by comprising the steps that (1) files are selected and stored in a request queue; (2) the files in the request queue sequentially sends uploading requests to a server; (3) after the server receives uploading request messages, the file sizes are acquired first; (4) a server end reads binary stream data, a binary stream is divided into multiple blocks according to the writing size at each time, and each binary stream server writs while reads; (5) after the uploading requests in the request queue are sent successfully, a browser end acquires the uploading progress and displays the uploading progress on a webpage; (6) after the browser end receives a successful processing result, the next file in the request queue uploads the request. According to the method for processing uploading of the multiple-instance large files based on the browser, the browser end is used for controlling concurrent request numbers, the method for reading and writing the files of the server is changed, and therefore the uploading concurrent processing capacity of the server is improved.

Description

A kind of processing method of the many examples big file uploading based on browser

Technical field

The present invention relates to networking technology area, relate in particular to a kind of processing method of the many examples big file uploading based on browser.

Background technology

File based on browser is uploaded, and is the function that great majority all possess based on browser program.First, the file size of uploading based on browser can be subject to the restriction of server free memory.When particularly concurrent, if there is the upload file simultaneously of too much process, can cause server end low memory.In addition, user cannot see the progress of uploading in real time, causes user to experience poor.

Summary of the invention

The object of the invention is to overcome the shortcoming of prior art, a kind of processing method of the many examples big file uploading based on browser is provided.

For solving above technical problem, technical scheme of the present invention is: a kind of processing method of the many examples big file uploading based on browser, and its difference is, its step comprises:

1) during user's select File, for the browser of not supporting HTML5 language, once can only select a file, select a file to preserve a upload request in request queue; For the browser of supporting HTML5 language, once can select a plurality of files, at this moment successively the file of selection is saved in request queue;

2) file in request queue sends upload request to service successively, and request header can comprise a document size information; When a file, upload, other upload request can be in wait state;

3) server receives after upload request message, first obtains file size; When file size surpasses server end setting upload size limits, the mistake that server backspace file is excessive, client, to returning after mistake, can be carried out next file upload request; For not surpassing the request of size restriction, service end can be opened interface channel, receives upload file binary stream data;

4) service end reads binary stream data, according to the large young pathbreaker's binary stream that writes of setting at every turn, is divided into polylith, and every binary stream server writes while reading, and upgrades the progress of the uploading variable of service end simultaneously; It is complete that every binary stream data write, and discharges the current server memory taking;

5), after the upload request in request queue sends successfully, browser end starts the progress of the uploading variable of each one second request service end; Obtain after the progress of uploading, on the page, show;

6) file upload request is after server process, and server returns successfully.View side receives after successful result, starts next file upload request in request queue.

Contrast prior art, beneficial features of the present invention is: by browser end, control concurrent request number, and change the method that server reads and writes file, thereby reach server to uploading the lifting of concurrent processing ability.Meanwhile, reading in real time the progress of uploading can experience for user provides good user.

Accompanying drawing explanation

Fig. 1 is the theory diagram of the embodiment of the present invention.

Embodiment

Below by embodiment, by reference to the accompanying drawings the present invention is described in further detail.

Please refer to Fig. 1, the present invention is based on the processing method of many examples big file uploading of browser, its step comprises:

1) during user's select File, for the browser of not supporting HTML5 language, once can only select a file, select a file to preserve a upload request in request queue; For the browser of supporting HTML5 language, once can select a plurality of files, at this moment successively the file of selection is saved in request queue;

2) file in request queue sends upload request to service successively, and request header can comprise a document size information; When a file, upload, other upload request can be in wait state;

3) server receives after upload request message, first obtains file size; When file size surpasses server end setting upload size limits, the mistake that server backspace file is excessive, client, to returning after mistake, can be carried out next file upload request; For not surpassing the request of size restriction, service end can be opened interface channel, receives upload file binary stream data;

4) service end reads binary stream data, according to the large young pathbreaker's binary stream that writes of setting at every turn, is divided into polylith, and every binary stream server writes while reading, and upgrades the progress of the uploading variable of service end simultaneously; It is complete that every binary stream data write, and discharges the current server memory taking;

5), after the upload request in request queue sends successfully, browser end starts the progress of the uploading variable of each one second request service end; Obtain after the progress of uploading, on the page, show;

6) file upload request is after server process, and server returns successfully.View side receives after successful result, starts next file upload request in request queue.

At traditional file, upload in mode, during file upload request that server receives, whole file can be read in internal memory, and then write disk.Therefore, each uploads the internal memory that process can at least take institute's upload file size, so that this can cause server can receive the process concurrent number that file uploads is very little.Therefore the present invention controls concurrent request number by browser end, at browser end, a plurality of files of selecting is sorted and queue processing, guarantee that one of a browser end only triggers a upload request, and then concurrent number is uploaded in minimizing to a certain degree; And change the method that server reads and writes file, thereby reach server to uploading the lifting of concurrent processing ability.

For each different process of uploading, server need to be preserved the file writing progress of each process, and browser end just can carry out inquiry progress by the sign of each process like this, reads in real time the progress of uploading and can experience for user provides good user.

Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
