Preferably, whether the file destination extension name in the above-mentioned access address for judging to obtain is correct, may include：Judge
It is extended with the presence or absence of normative document identical with above-mentioned file destination extension name in preset at least one criteria file extension
Name, if not, judging that above-mentioned file destination extension name is incorrect；If so, judging that above-mentioned file destination extension name is correct.
Wherein, above-mentioned preset at least one criteria file extension can be pre-stored existing file extension
Or common file extension, for example, in the business of order video, common video file extension name (such as *
.mp4, * .rmvb, * .mpg, * .mpeg and * .mpe etc.) web of terminal applies for playing video can be stored in advance in
In the page.
Continue to use precedent, it is assumed that the extension name of certain access address is accidentally written as " * .mp4 " (before mp4 more skies
Lattice), above-mentioned access address fault tolerance facility can compare " * .mp4 " at least one criteria file extension, due to standard
File extension " * .mp4 " and " * .mp4 " are different, and " * .mp4 " is also differed with other criteria file extensions, then can determine that
Extension name " * .mp4 " is incorrect.
It is of course also possible to be correct there are file destination extension name, but the corresponding access of file destination extension name
The case where location still cannot open, reason may be that browser used is not supported to open the file or access of the type
The problems such as location is not present.
It is S210, incorrect in response to above-mentioned file destination extension name, it determines and matches with above-mentioned file destination extension name
Criteria file extension；
In one example, above-mentioned file destination extension name and above-mentioned standard file extension can be carried out to fuzzy

Mode one：Refer to Fig. 2, " determining and extending famous prime minister with the file destination in S210 in embodiment illustrated in fig. 1
The criteria file extension matched " can specifically include：
S211, from above-mentioned at least one criteria file extension, determine criteria file extension alternative collection；
Wherein, above-mentioned standard file extension alternative collection includes：Matching degree between above-mentioned file destination extension name is big
In the criteria file extension of matching degree threshold value.
Preferably, the embodiment of the present invention can extend above-mentioned at least one criteria file extension and above-mentioned file destination
Name is compared, to obtain the matching degree between each criteria file extension and above-mentioned file destination extension name, i.e., at least one
Similarity degree between criteria file extension and above-mentioned file destination extension name is more than or not less than default in above-mentioned matching degree
The criteria file extension of matching degree threshold value be just put into criteria file extension alternative collection.
Above-mentioned matching degree threshold value can carry out flexible design according to actual needs.In one example, above-mentioned matching degree threshold value
It includes percentage that exemplary can obtain, such as 80%.
By taking matching degree threshold value is 80% as an example, it is assumed that share 5 criteria file extension A-E, wherein normative document extends
Name A-C and the matching degree of file destination extension name are more than 80%, then criteria file extension alternative collection includes above-mentioned standard file
Extension name A-C.
In another example, above-mentioned matching degree threshold value may include that the identical number N of character in file extension, N are just
Integer.
Preferably, the embodiment of the present invention can be extended in above-mentioned at least one criteria file extension and above-mentioned file destination
Name determines the matching degree between above-mentioned at least one criteria file extension and above-mentioned file destination extension name when being compared, i.e.,

It is then identical there are two character between criteria file extension " * .mp4 " and " * .M4 ", then " * .mp4 " can be determined as above-mentioned standard
One in file extension alternative collection, and then determination obtains criteria file extension alternative collection from criteria file extension.
S212, according to the descending sequence of above-mentioned matching degree, to the standard in above-mentioned standard file extension alternative collection
File extension is ranked up, and obtains file extension sequence；
Continue to use precedent, it is assumed that common video file extension name is in the web page of the terminal applies for playing video
Middle storage, such as * .mp4, * .rmvb, * .mpg, * .mpeg, * .mpe, * .avi, * .asf, * .rm, * wmv, * .mkv, * .vob
And * .divx.The file destination of the access address of technical staff's typing extends entitled " * .me ", can be by file destination extension name
" * .me " is compared to obtain matching degree with common video file extension name, and obtains criteria file extension according to matching degree
Alternative collection, at least there are two characters and target text in each criteria file extension in the criteria file extension alternative collection
Character in part extension name is identical.For example, may include " * .mpeg and * .mpe " in above-mentioned standard file extension alternative collection, so
Afterwards, each criteria file extension in criteria file extension alternative collection is sorted according to matching degree size, obtains file extent
Name sequence { * .mpeg, * .mpe }.
S213, primary criteria file extension will be located in above-mentioned file extension sequence, be determined as and above-mentioned mesh
