Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
In embodiments of the present invention, in order to prevent that file is downloaded, server end can prevent that to needs file or the catalogue downloaded from arranging anti-the download in advance, during file in receiving these files of client-access or catalogue, server end judges whether the file of request has set anti-download, allows normal the download if do not arrange then return normal link; If be provided with anti-the download for the file of asking, then server increases file in described file or the catalogue for preventing the label information of download file in the information of returning.After client is sent the request of the file in access file or the catalogue, whether judgement comprises that in the information that server returns with described file or directory markeys be the label information of anti-download file, if comprise described label information, then the significant data of the file in described file or the catalogue is prevented download process.
More than the embodiment of the invention has been done the description of a summary, below in conjunction with description of drawings each specific embodiment of the present invention.
As shown in Figure 1, the schematic flow sheet for an embodiment of the anti-download process method of the file of a kind of server end of the present invention comprises:
101, anti-download file or catalogue are set;
Particularly, file destination or target directory are set to anti-file or the catalogue of downloading;
103, receive access request after, increase the label information of anti-download file;
Particularly, after the request of receiving the described file destination of access or target directory, the file that increases in the information of returning in described file destination or the target directory is the label information of anti-download file;
Further, the method that specifically increases label information can be:
A, will be behind the chained address of the file in described file destination or the target directory in the information of returning increase the anti-tag field of downloading; For example can Zeng Jia ﹠amp; The save=false field represents that this file has been set up anti-download, also can increase other and be used for the field of mark;
B, extra increase is used for specially tab file and is the part of anti-download file in the information of returning, and for example can additionally increase block of information, particular content Ke Wei ﹠amp; Save=0 represents that this file has been set up anti-download.
Be exemplary illustration only below, the anti-form of downloading label information be set be not limited to this that as long as server end and client are made an appointment, client can identify anti-Download Info and get final product.
After server end has carried out above-mentioned processing, after client is sent download request, can carry out to the file that has passed through above-mentioned setting certain processing and be downloaded preventing, as described below:
As shown in Figure 2, the schematic flow sheet for an embodiment of the anti-download process method of the file of a kind of client of the present invention comprises:
201, send the request of access file;
Particularly, send the request of the file in access file or the catalogue;
203, receive the information of returning;
Particularly, the information returned according to described request of reception server end;
205, judge whether to comprise label information;
Particularly, judge whether comprise in the described information that with described file or directory markeys be the label information of anti-download file;
207, anti-download process;
Particularly, if judgement comprises described label information in 205, the significant data of the file in described file or the catalogue is prevented download process;
Generally, affecting the normal significant data that uses of file is the first blocks of data, and the large I of the first blocks of data is set according to file actual size and actual needs, and for example for the file of a 100M, the first blocks of data can be 256K; Can be not limited to above-mentioned concrete form in the reality, just describe for example herein;
Below describe as the first blocks of data as example take significant data, concrete anti-download process method can be:
