Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is
The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
Fig. 1 is the flow chart of the acquisition file type processing method of the embodiment of the present invention.As shown in figure 1, the present invention is implemented
The acquisition file type processing method of example includes：
S11：After sending the download request of file to be downloaded, receive the URL address of the described file to be downloaded returning；
Wherein, locally send after the download request of file to be downloaded to server, it is to be downloaded that meeting the reception server returns
The URL (Uniform Resource Locator, URL) of file.One complete URL includes following a few portion
Point：(1) protocol section：As Http, Ftp etc.；(2) domain name part；(3) port section, following after domain name is port, domain name
Use and port between ":" as separator；(4) virtual directory part：First "/" after domain name starts to last
Till "/", it is virtual directory part；(5) file names portion；(6) anchor section, starts to last from " # ", is all anchor section；(7)
Argument section, from "？" to start part between " # " be argument section.
For example, the URL of the file to be downloaded that local reception is arrived is " http://wenku.baidu.com:8080/
view/index.asp？BoardID=5＆ID=24618＆page=1#n ame ", this URL are divided into 7 parts：Wherein,
" http " is protocol section；" wenku.baidu.com " is domain name part；" 8080 " are port section；" view " is virtual mesh
Record part；" index.asp " is file names portion；" name " is anchor section；" boardID=5＆ID=24618＆page=1 "
For argument section.
S12：Obtain the file name suffix information of described file to be downloaded according to described URL address resolution；
S13：Determine the file type of described file to be downloaded according to described file name suffix information.
In actual applications, last "/" after domain name start to "？" till, it is file names portion, without
“？", then it is to start to " # " from last "/" after domain name, be file names portion, without "？" and " # ", then
Last "/" start to finish after domain name, is all file names portion.
It is understood that the file type downloading file can be identified according to file name suffix, such as word document
File name suffix be " .doc ".
The processing method obtaining file type provided in an embodiment of the present invention, when downloading file to be downloaded, receives service
The URL address of the file to be downloaded that device returns；Obtain the file name suffix letter of file to be downloaded according to described URL address resolution
Breath；Determine the file type of file to be downloaded according to described file name suffix information, it is to avoid simple in prior art rely on clothes
