Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Before introducing the present invention program, first description below explanation is done to the principle that realizes of the present invention program.
HTML (Hypertext Markup Language) (English: HyperTextTransferProtocol, be called for short: HTTP) be a kind of procotol that the Internet is most widely used.Http protocol is a kind of typical request-response protocol, and that is, user can send resource request by browser to server, and server then can respond this request.Particularly, response contents main body and head response (ResponseHeader) can be comprised in the response that server returns.
Usually, in order to improve response speed, browser can by content cachings such as some requested picture, files in this locality.For example, for the pictures A that webpage is shown, browser can send resource request to server, after obtaining picture A, picture A is buffered in this locality.Like this, browser next time to server request picture A time, server can judge that whether picture A after request, renewal occurred in last time, if picture A is updated, the picture A after upgrading, then by response, is sent to browser by server; If picture A does not upgrade, server is then by response, and return 304 conditional codes representing that resource is unmodified to browser, corresponding to this, the picture A of local cache just can be presented to user by browser.With return compared with picture A to browser, transmission state code just can reduce transmitted data on network, contributes to improving response speed.
In conjunction with the feature of above-mentioned HTTP agreement, namely, user terminal can the resource that provides of caching server, the present invention program, the static resource that a renewal frequency is very low is selected the page can shown from website, as the logo picture of website homepage, this static resource is set to permanently effective, so, user first access websites time, the User Identity that just can will generate for this user, write above-mentioned static resource and feed back to user terminal and preserve, that is, carry the static resource of User Identity, can as the object of the present invention program's user identity identification.Corresponding to this, when user's access websites next time, browser identify this static resource be permanently effective after, just can directly read from local cache and be loaded on Website page, like this, just by identifying the User Identity carried in static resource, realizing the present invention when user forbids cookie, accurately identifying the object of user identity.
See Fig. 1, show the flow chart of the method for identifying ID of server side of the present invention, can comprise:
S101, receive the access request that user terminal sends, described access request comprises the identify label of designated pictures.
Usually, when user's Website login, in order to the complete page representing website to user, user terminal can send access request to Website server, so that the resource in load page.Such as, can return to by website the JavaScript script that the page of user terminal browser runs, send access request to server.
Particularly, this step, for the access request of designated pictures, can be sent to server by user terminal during resource in load page mentioned above; Or also can be sent to server when user triggers some predeterminable event by user terminal, if predeterminable event is click event, the embodiment of the present invention can be not specifically limited this.
In addition, when practical application, can chosen in advance using any pictures on the page as designated pictures, so, user terminal just when needed, can send the access request that comprise this designated pictures identify label to server.For example, the form of designated pictures can be png, gif etc., designated pictures identify label can be that URL is (English: UniformResoureLocator, Chinese: URL(uniform resource locator)) etc. can carry out uniquely identified information to designated pictures, the concrete manifestation form etc. of the embodiment of the present invention to picture format, identify label can be not specifically limited.
For example, in the present invention program, designated pictures can be the picture that on the page, arbitrary renewal frequency is low, as the logo picture of website homepage; Or, designated pictures also can be generate not easily by the specific pictures that user realizes, as transparent picture.Particularly, in order to reduce that the page loads specific pictures as far as possible, on the impact that webpage representation effect causes, specific pictures can be arranged on position that the page not easily checked by user, or, also can reduce the impact of specific pictures on page effect by the DIV that the page is arranged (English: DIVision, Chinese: the position of cascading style table unit and level) layer, as specific pictures being arranged on DIV layer position, and blocked by DIV layer.
S102, according to the identify label of described designated pictures, obtains original designated pictures.
After server receives access request, just can utilize the designated pictures identify label of carrying in access request, obtain original designated pictures.Particularly, server can judge whether in book server, find the picture with described identify label, if so, then the picture found is defined as original designated pictures; If not, then a pictures can be built as original designated pictures.
S103, writes the appointed area of described original designated pictures, obtains described designated pictures by the User Identity generated.
Server obtains original designated pictures, and for after user generates unique user identity mark, just User Identity can be write in original designated pictures, obtaining can as the designated pictures of user identity identification object in the present invention program.Wherein, a string random code that User Identity can generate for server, the constituted mode, length etc. of the present invention to random code can be not specifically limited.
Particularly, the present invention program provides the scheme that two kinds obtain designated pictures, Fig. 2 and Fig. 3 place that can vide infra to this is introduced, and wouldn't describe in detail herein.
S104, send access response to described user terminal, described access response comprises described designated pictures and status indicator, and described status indicator is permanently effective for representing described designated pictures.
From realizing introducing of principle to the present invention program above, in order to can user next time access websites time, accurately carry out user identity identification, the status indicator that one represents designated pictures validity also should be set, like this, when user's access websites next time, user terminal just can read this permanently effective designated pictures from local cache, be loaded on the page, and then from this designated pictures, obtain User Identity again, realize the object of user identity identification of the present invention.As a kind of example, status indicator can write-access response head response in.
In conjunction with practical application, the present invention program at least obtains designated pictures by following two kinds of modes.
Scheme one, when appointed area immobilizes, obtains the scheme of designated pictures, specifically can flow chart shown in Figure 2, can comprise:
S201, is converted to pixel color value by described User Identity;
S202, the pixel color value utilizing conversion to obtain, covers the color value of described appointed area place pixel, obtains described designated pictures.
For example, User Identity of the present invention can be String type, first the User Identity of String type can be converted to binary format, and then be converted to pixel color value again, as be converted to the color value under rgb color pattern.
Such as, getBytes (" UTF-8 ") can be passed through, User Identity is converted to UTF-8 (English: 8-bitUnicodeTransformationFormat, also known as ten thousand country codes) byte arrays under coded format, realize the object User Identity of String type being converted to binary format above.
Such as, if under rgb color pattern, each Color Channel represents color value by 8 color depths, namely in R, G, B tri-Color Channels, the span of often kind of color is 0 to 255, then whether there is sign bit according to binary system byte, binary data is converted to pixel color value above and can be presented as following two kinds of examples.What is called has sign bit to can be understood as in binary data, and be provided with one and be exclusively used in the bit representing that data are positive and negative, represent when this bit is 1 that data are negative, represent when this bit is 0 that data are positive number, usually, sign bit is arranged on the highest order of byte.
Example one, the byte in byte arrays is without sign bit, and namely the span of each byte is 0 to 255, and so, the binary data be converted to by User Identity can directly as color value.
Example two, byte in byte arrays has sign bit, namely the span of each byte is-128 to 127, so, each byte in array and int type numeral 0xFF can be carried out AND operation bit-by-bit, be converted to the int type numeral of this byte in 0 to 255 scope, namely the int type numeral that this is converted to can be used as the color value of the single channel of 8 color depth RGB.
Only by a concrete example above, the explanation explanation that process User Identity being write designated pictures to the present invention is carried out.In application process, can in conjunction with embody rule situation, take adaptive scheme to realize the conversion of User Identity to pixel color value, the embodiment of the present invention can be not specifically limited this.
Because appointed area immobilizes in this programme, therefore after conversion obtains pixel color value, just this color value can be utilized to cover original color value of pixel in appointed area, realize said object User Identity being write appointed area of the present invention, thus obtain the designated pictures of carrying User Identity in the present invention program.
In addition, it should be noted that, when User Identity being converted to the color value under rgb color pattern, in order to reduce the pixel number shared by write User Identity as far as possible, R, G, B and transparency four passages can be utilized, represent User Identity.Or, the passage portion in four passages also can be utilized to represent User Identity, so can avoid occurring color change in picture as far as possible, reduce the impact that write User Identity produces picture.
Scheme two, when appointed area is variable, obtains the scheme of designated pictures, specifically can flow chart shown in Figure 3, can comprise:
S301, is converted to pixel color value by described User Identity, and obtains the color value of each pixel in described original designated pictures;
S302, determines described appointed area from described original designated pictures, and the pixel color value that the color value of described appointed area place pixel and the conversion of described User Identity obtain is closest;
S303, the pixel color value utilizing described conversion to obtain, covers the color value of described appointed area place pixel;
S304, obtains the positional information of described appointed area, writes in the fixed area of described original designated pictures, obtains described designated pictures.
Because server generates the randomness of User Identity, after User Identity may be caused to write original designated pictures, there is uncertain change in picture, as there is obvious spot in picture.Corresponding to this, this programme can pass through picture Processing Technique, finds out the region that a pixel color value be converted to User Identity is the most close, as appointed area in original designated pictures.Like this, the visual impact that write User Identity causes picture can be reduced as far as possible.
Particularly, two regions in the original designated pictures of this programme, can be comprised: one is variable appointed area, for writing User Identity; One is constant fixed area, for writing the positional information of appointed area.Usually, positional information wants shorter compared with User Identity, needs the pixel that takies just few during write picture, and write compared with User Identity in constant region, in constant region writing position information, less on the impact of picture generation.
