First kind of batch documents transmission method flow chart that Fig. 1 provides for the embodiment of the invention.As shown in Figure 1, the batch documents transmission method that present embodiment provides specifically can be applied to the network application scene based on the HTTP transmission, especially crossing internet carries out the application scenarios of transfer of data in enormous quantities, as shown in Figure 2, in this application scenarios, comprise Web server 82 and a plurality of client 81.Communicating by letter between client 81 and the Web server 82 based on HTTP.The batch documents transmission method that present embodiment provides can be carried out by client Client, and this client can realize by the electronic equipment that personal computer, notebook computer, panel computer, smart mobile phone or server etc. have a data-handling capacity.

The batch documents transmission method that present embodiment provides specifically comprises:

Step C10, send first HTTP HTTP request to Web server, wherein, carry in the described HTTP request and be used to indicate the file object sign of waiting to obtain file, the described quantity of obtaining file of waiting is at least two;

Particularly, the user is by the client-access Web server, to obtain file from Web server.HTTP is the application layer protocol that operates on the TCP (Transmission Control Protocol, transmission control protocol), and client is at first initiated the TCP connection request to Web server, is connected to set up TCP with Web server.After this TCP connected foundation, client connects by TCP again and Web server communicates.

Client sends HTTP request to Web server, the one HTTP request comprises header field (Header) and data field (Body), can comprise a plurality of headers in the header field, when comprising a plurality of header in the header field, specifically can cut apart by carriage return between the header, header field and data field can be cut apart by null.

Specifically in order to the required file that obtains of indication client, file promptly to be obtained waits that the quantity of obtaining file is at least two to the file object sign.Particularly, client can the acquisition request Web server in All Files under certain catalogue, then this document object identity can be the title of this catalogue, the perhaps All Files that can the acquisition request Web server be generated in certain time range of client, then this document object identity can be this time range.Under above-mentioned application scenarios, client can not known the quantity of file of acquisition request and the title of file.If when the user selected to obtain some specific file in the Web server by client, then this document object identity can be the filename of file.The file object sign can specifically be provided with according to actual conditions, does not exceed with present embodiment.This document object identity can be carried at the form of header in the header field of HTTP request, also can be carried in the HTTP request msg territory.

Web server receives HTTP request, and request is resolved to a HTTP, extracts this document object identity from HTTP request, and determines file to be obtained according to this document object identity.Web server obtains first cuts apart sign (Block Splitter), this first is cut apart sign and is specifically as follows by preset algorithm and generates in advance, and Web server also can be after receiving HTTP request generates this by preset algorithm again and first cuts apart sign.First cuts apart sign is specifically as follows random number, for example general unique identifier (Universally Unique Identifier is called for short UUID), the perhaps combination of a plurality of UUID.Also can adopt other presetting methods to generate this and first cut apart sign, to distinguish and get final product, not exceed with present embodiment with waiting to obtain file with first complexity of cutting apart sign that guarantees to generate.If this first is cut apart to be designated in advance and generates, then can make an appointment by procotol and client, so that can discerning this, client first cuts apart sign.If this first is cut apart and be designated that Web server generates in real time, then Web server can carry in the header field of first http response that sends to client in order to indicate this first header of cutting apart sign.

Web server generates and to include this data block of waiting to obtain file (Data Block) according to waiting to obtain file, and the quantity of for example waiting to obtain file is N, and N is integer and N 〉=2, and then the quantity of the data block of Sheng Chenging also is N.Except comprising this file to be obtained, can also comprise that other and this wait to obtain the relevant information of file in the data block, for example index, length information or checking information etc. also can include only this file to be obtained.Web server inserts one first between per two data blocks cuts apart sign, promptly data block between any two by first cut apart the sign cut apart, form the data field of first http response, as shown in Figure 3.In actual applications, can also insert one first at the head of data field and cut apart sign, cut apart sign in one first of the afterbody insertion of data field, as shown in Figure 4, the afterbody of data field can also insert and finish sign, finishes to indicate this data field.This finishes sign for example can be two continuous carriage return characters.Web server sends to client with this first http response.

First http response that step C20, the described Web server of reception send according to described file object sign, wherein, carry at least two data blocks in the data field of described first http response, cut apart sign by first between per two data blocks and cut apart, each described data block comprises a file described to be obtained;

Step C30, described first http response is resolved, obtain described at least two files to be obtained.

Particularly, client receives this first http response that Web server sends, first http response is resolved, cut apart sign and each data block can be extracted, and then obtain file to be obtained in each data block by discerning first in first http response.

The batch documents transmission method that present embodiment provides, client sends first HTTP HTTP request to Web server, wherein, carry in the one HTTP request and be used to indicate the file object sign of waiting to obtain file, wait that the quantity of obtaining file is at least two, receive first http response that Web server sends, wherein, carry at least two data blocks in the data field of first http response, cutting apart sign by first between per two data blocks cuts apart, each data block comprises a file to be obtained, and first http response is resolved, and obtains at least two files to be obtained.Because client carries the file object sign that is used to indicate at least two files in the HTTP request that Web server sends, correspondingly, Web server comprises in the http response that client is returned by first cuts apart at least two files that sign is cut apart, at least two files of transmission in a HTTP transmission have been realized, improve efficiency of transmission, reduced overhead.

In the present embodiment, carry first in the header field of described first http response and cut apart marking head information; Correspondingly, step C30, described described first http response is resolved, obtains described at least two files to be obtained, specifically can comprise:

Particularly, the form of first http response specifically can be with reference to Fig. 5.Carry first in the header field of this first http response and cut apart marking head information (Block Splitter Header), can also carry other headers (Other Headers) in the header field.Client can be cut apart marking head information according to first in the header field of first http response and determines that this first cuts apart sign.

In the present embodiment, also carry second in the header field of described first http response and cut apart marking head information, each described data block comprises index, describedly waits to obtain file and check information;

Describedly from each described data block, extract file described to be obtained, specifically can comprise:

Particularly, Web server can not only comprise this file to be obtained according to waiting to obtain the data block that file generates, and can also comprise that this waits to obtain the index and the check information of file.Index is specifically as follows the filename of waiting to obtain file.Web server can wait to obtain the file allocation sequence number for each determining at least two according to file object sign when waiting to obtain file, and index also can be this sequence number.Check information is specifically as follows to treat and obtains file and handle by default checking algorithm that the back generates, should default checking algorithm can for but be not limited to MD (Message DigestAlgorithm, Message Digest 5) 5 or SHA-1 digest algorithms such as (Secure Hash Algorithm, Secure Hash Algorithm).This check information is used to treat the integrality and the fail safe of obtaining file and carries out verification.Web server obtains second cuts apart sign (Inner Splitter), and this second generating mode of cutting apart sign can not repeat them here with reference to first generating mode of cutting apart sign.Web server second is cut apart sign and is generated second and cut apart marking head information (Inner Splitter Header) according to this, by second cut apart sign with index, wait to obtain file and checking information separates in twos, index, wait that the order of obtaining file and checking information can arrange according to preset rules.A kind of implementation as shown in Figure 6.

Client will be in will waiting to obtain the process that file extracts from data block, can be at first according to second cutting apart marking head information and determine that this second cuts apart sign in the header field of first http response, cut apart sign by second of identification data block, with with index, wait to obtain file and checking information extracts respectively, and this file to be obtained is tested by checking information, if verification succeeds, this can be waited to obtain the corresponding preservation of file and index, if the check failure then can be obtained file again to Web server.

In the present embodiment, each described data block comprises index, describedly waits to obtain file and check information; Describedly from each described data block, extract file described to be obtained, specifically can comprise:
