Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
It is right first below in order to make those skilled in the art be easier to understand technical solution provided in an embodiment of the present invention
Relevant technical term is introduced.
ETag is the entity indicia Entity of URL (Uniform Resoure Locator, uniform resource locator)
Tag.ETag is the component part of the protocol header of HTTP (HyperText Transfer Protocol, hypertext transfer protocol).
In the prior art, ETag is mainly used for that picture repeated downloads is avoided to result in waste of resources, and specific mechanism is as follows: browser first
When a certain webpage of secondary browsing, browser initiates the request of download pictures to server.Server returns to picture, and adds one for picture
A identity ID is as label.In this way, user is refreshing the webpage, when requesting same picture again, browser can should
ID is carried in the ETag of request message.After server receives the request message, the request message is parsed, judges ID and expired
Time directly returns to 304 status codes, instruction if server finds that same user downloaded this picture before expired duration
Browser directly reads the picture of local cache, avoids the wasting of resources.
After the Cookie of client-cache is deleted in the prior art, server can not carry out user's identification, and how sharp
User's identification is carried out with ETag, those skilled in the art do not consider also at present.
Fig. 1 is a kind of schematic diagram of implementation environment of the embodiment of the present invention, as shown in Figure 1, the implementation environment may include
Client 110 and server 120, wherein the client 110 can be smart phone, tablet computer etc..With client in Fig. 1
End 110 is illustrated for laptop.The server 120 can be web page server.
Specifically, which is equipped with browser 1101, when using the browser 1101 browsing webpage, client
End sends resource access request to server 120 by network, to access all kinds of websites.
The embodiment of the present invention provides a kind of user's knowledge method for distinguishing, and the executing subject of this method can be shown in Fig. 1
Server 120.As shown in Fig. 2, this method comprises:
S201, server receive the resource access request that client is sent, and the resource access request includes unified resource
Finger URL URL.
Uniform resource locator is succinct to the position for the resource that can be obtained from internet and one kind of access method
Expression, be the address of standard resource on internet.Each file on internet has a unique URL, it includes
Information indicates how the position of file and browser should handle this document.That is, the resource access request is used for
The corresponding resource of the URL is obtained from server.
S202, the server are distributed when the resource access request does not include entity indicia ETag for the client
User's unique identification, user's unique identification identify the client for the server.
Wherein, which is the request of http protocol, protocol header of the server in the resource access request
In when ETag has not been obtained, it is believed that the client is to access the website for the first time.In this case, which is the client
One user's unique identification of end distribution, is used for the uniquely tagged client.
It is worth noting that, there is following two in the reason of not including ETag in the resource access request, first is that the client
Before from having not visited the server, the browser rs cache second is that client has been emptied after accessing the server, for
Both of these case when server does not obtain ETag in resource access request, thinks that the client is to access for the first time.
S203, the server generate the ETag including user's unique identification, and the ETag and URL is corresponding
Resource be back to the client.
Wherein, the client is after the ETag for receiving server distribution, and when subsequent each access server is equal
The resource access request for carrying the ETag is sent to the server.
Therefore, in a kind of possible implementation of the embodiment of the present invention, if the resource access that the server receives
Include ETag in request, then obtains user's unique identification in the ETag, and according to user's unique identification identification
Client, wherein user's unique identification is that the server distributes to the client.
Specifically, the server is when thinking the client is to access for the first time, according to resource access request to the client
End sends resource access response, carries user's unique identification in the ETag in the protocol header of the resource access response.The resource
Message body portion in access response carries the corresponding resource of the URL.In this way, the client obtains the resource of this request,
And in the subsequent access resource, user's unique identification, server can be carried in the ETag of resource access request
After getting user's unique identification, can to the client carry out user's identification, with the session to the client carry out with
Track.
By adopting the above technical scheme, server, can be according to this after the resource access request for receiving client transmission
User's unique identification in the ETag of resource access request identifies the client, the cache file of ETag and browser
It is stored together, in order to improve the loading speed of resource, user will not usually be emptied the cache file of browser, therefore, In
In the case that Cookie is deleted, server still is able to identify client, solves the prior art in Cookie quilt
Just the technical issues of user's identification can not be carried out after deletion.
In order to make those skilled in the art more understand technical solution provided in an embodiment of the present invention, below to above-mentioned side
Method step is described in detail.
It is worth noting that is carried originally in existing ETag is the summary info of picture resource, server is being obtained
It to after the summary info, can be compared with the summary info of picture resource current in server, if the two summary info
Unanimously, show that picture resource is not changed, server can then return to 304 yards of instruction client acquisition figures in local cache
Piece resource shows that the picture resource of server changes if the two summary info is inconsistent, in this case, service
The summary info of picture resource after variation and the picture resource after variation can be back to client as new ETag by device
End.
That is, the resource access request message that client is sent to server may wrap in existing http protocol
Include ETag.It in this case, include ETag in the resource access request which receives, then the server can determine
User's unique identification whether is carried in the ETag, if not carrying user's unique identification in the ETag, is distributed and is used for the client
Family unique identification, and generating includes that be sent to the client current to replace the client by the ETag of user's unique identification
ETag。
Specifically, in order to guarantee the problem of ETag can result in waste of resources originally to avoid picture repeated downloads, in this hair
In a kind of possible implementation of bright embodiment, when the corresponding resource of URL in resource access request is picture resource, with
The upper generation includes that the ETag of user's unique identification is specifically included: user's unique identification and the picture are provided
The summary info in source is spliced into ETag.In this way, client is accessed again in the resource access request that the server is sent
ETag had not only included the unique identification of user but also had included the summary info of picture resource, so that server both can be according to user
Unique identification identifies client, and the repeated downloads of picture can be avoided according to the summary info of picture resource.
Wherein, the summary info of the picture resource can be the MD5 (Message-Digest of picture resource
Algorithm 5, Message-Digest Algorithm 5) value.
Further, which obtains in ETag after the subsequent resource access request for getting client transmission
Summary info, corresponded in determining the server resource request access in URL picture resource summary info and institute
State summary info in ETag it is inconsistent when, the server is unique by the summary info of the picture resource after variation and the user
Mark is spliced into new ETag, and the picture resource after the new ETag and variation is back to the client.Meanwhile
The server obtains user's unique identification in the ETag of the resource access request, identifies the client, the visit to the client
It asks and is recorded.
Corresponded in determining the server resource request access in URL picture resource summary info with it is described
When summary info in ETag is consistent, the server to the client return 304 status codes, be used to indicate the client from
The picture resource is obtained in local cache, the repetition acquisition for avoiding picture resource results in waste of resources.
Using the above method, the embodiment of the present invention ensure server be based on ETag can be avoided client repeated downloads figure
Under the premise of piece, it is also possible that server can identify client according to ETag, the prior art is solved in Cookie quilt
Just the technical issues of user's identification can not be carried out after deletion.
Fig. 2 is the explanation carried out using server as executing subject to user identification method provided in an embodiment of the present invention,
Fig. 3 is the user identification method shown according to another exemplary embodiment, embodies the interaction between client and server, such as
Shown in Fig. 3, comprising:
S301, user end to server send resource access request, and the resource access request includes unified resource positioning
Accord with URL.
S302, server receive the resource access request, and when the resource access request does not include ETag, for visitor
Family end distributing user unique identification.
Wherein, user's unique identification identifies the client for the server.
S303, server generate the ETag including user's unique identification, and the ETag and URL is corresponding
Resource be back to client.
S304, client receive the corresponding resource of the URL and ETag that server is sent.
Wherein, the ETag includes user's unique identification that server is client distribution.
S305, user end to server send the resource access request including the ETag.
S306, server receive the resource access request including the ETag, and according to the user in the ETag
Unique identification identifies the client.
Using the above method, when the subsequent each picture server of client sends resource access request, asked in resource access
User's unique identification that server distribution is carried in the ETag asked, in this way, server can be to this according to user's unique identification
Client is identified.The cache file of ETag and browser is stored together, in order to improve the loading speed of resource, Yong Hutong
Chang Buhui empties the cache file of browser, and therefore, in the case where Cookie is deleted, server still is able to client
End is identified solve the technical issues of prior art just can not carry out user's identification after Cookie is deleted.
Above-mentioned to be merely illustrative, in some cases, the resource access request that client is sent to server includes
ETag, but the ETag does not carry user's unique identification of the client.It can rectify to guarantee server always for client
True distributing user unique identification, in the embodiment of the present invention, server, can also be really after determining that resource access request includes ETag
Whether the fixed ETag carries user's unique identification, and when the ETag does not carry user's unique identification, is client distributing user
Unique identification, and generate the ETag including user's unique identification and be back to client to replace the current ETag of client.
Ensure that the resource access request of the subsequent transmission of client carries user's unique identification.
