Description of drawings
By reading hereinafter detailed description of the preferred embodiment, various other advantage and benefits will become cheer and bright for those of ordinary skills.Accompanying drawing only is used for the purpose of preferred implementation is shown, and does not think limitation of the present invention.And in whole accompanying drawing, represent identical parts with identical reference symbol.In the accompanying drawings:
Fig. 1 shows a kind of according to an embodiment of the invention flow chart of steps of the address searching embodiment of the method that lost efficacy;
Fig. 2 shows the structured flowchart of a kind of according to an embodiment of the invention address searching device embodiment that lost efficacy.
Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in the accompanying drawing, yet should be appreciated that and to realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order to understand the disclosure more thoroughly that these embodiment are provided, and can with the scope of the present disclosure complete convey to those skilled in the art.
One of core idea of the embodiment of the invention is, website information and snapshots of web pages corresponding to described network address by gathering browser collection folder in many subscriber equipmenies are saved to database with website information and snapshots of web pages.When returning corresponding Search Results for searching request, judge whether described Search Results is the inefficacy network address, if server returns snapshots of web pages corresponding to network address to browser.
With reference to Fig. 1, show the flow chart of steps of the address searching embodiment of the method that lost efficacy according to an embodiment of the invention, specifically can may further comprise the steps:
Step 101: gather the website information of the browser collection folder of many subscriber equipmenies, preserve described website information to database, described website information comprises the snapshots of web pages of network address;
Snapshots of web pages, English name be Web Cache, the webpage buffer memory.Search engine is when webpage, webpage is backed up, exist in the server buffer of oneself, when the user clicks " snapshots of web pages " link in search engine, the Web page content revealing that search engine grasped and preserved at that time Spider (spider) system out is called " snapshots of web pages ".In the present invention, described snapshots of web pages can preserve be generated by the code that server obtain described webpage, perhaps, can preserve when unsuccessful at the code that described server obtains this webpage, and the notice browser is uploaded generation with the code of the webpage of correspondence.That is to say, snapshots of web pages is at some web page codes that are presented as of server side.
Web page code need just to refer to some special " language " of using in Web Page Design, then the designer is carried out being only the effect that we finally see after " translation " to code by browser by webpage is produced in these " language " tissue layouts.Code commonly used during present Web-Designing has HTML, JavaScript, and ASP, PHP, CGI etc., wherein HTML is most basic web page code.Described web page code can directly be obtained when resolving the request message of browser by server; Perhaps, described web page code also can obtain when the response message that the browser resolves server returns, and then web page code is uploaded onto the server.The benefit of obtaining web page code with server is to save like this user's surfing flow, minimally consume user bandwidth, when server is preserved the web page code failure, can notify browser to obtain web page code uploads, server is preserved described web page code again, can adopt the mode of compressed code that described web page code is uploaded when browser is uploaded described web page code, so also can reduce the roam of uploading, reduce bandwidth.
In specific implementation, it can be that number of site is maliciously usurped by other people in order to prevent own content that a kind of server is preserved the unsuccessful situation of web page code, can do some restrict access at own server, for example limit other machines to its access frequency, server just can not directly be preserved web page code like this, in specific implementation, server can carry out web page code hash algorithm and obtain web site contents checking string, described web site contents checking string and web site contents checking string in the default preservation check interface compared judge whether server is preserved web page code successful, server is preserved the web page code success if described web site contents checking string is present in the default preservation check interface, otherwise it is unsuccessful that server is preserved code.Those skilled in the art adopt other modes all to be fine, and the present invention is not restricted this.
Browser is kept in the database website information for follow-up search use after the website information of the browser collection folder that gathers many subscriber equipmenies.In specific implementation, the present invention can preserve website information with two databases, and one is content data base, and one is the snapshots of web pages database, the snapshots of web pages database is used for preserving the snapshots of web pages of network address, and the content data base user preserves network address other information except snapshots of web pages; Perhaps, the present invention also can set up a database, comprise two tables in the database, one is used for the storage snapshots of web pages, a content that is used for beyond the storage snapshots of web pages it will be understood by those skilled in the art that above-mentioned website information storage mode only is example of the present invention, those skilled in the art can adopt other storage meanss to store, and the present invention is not restricted at this.
Step 102: browser receives searching request and described searching request is sent to server;
Step 103: server grasps the webpage formation Search Results relevant with described searching request and returns to browser in database;
For example, when the user carries out keyword search in browser, browser sends to server with keyword after receiving user's the keyword of search, and crawl in the described content data base forms Search Results with the relevant web page contents of keyword and returns to browser server according to described keyword.In specific implementation, Search Results can sort according to the weight of webpage and then return, and also can sort according to additive method and return, and the present invention is not restricted at this.
Step 104: the described Search Results of browser-presented.
Step 105: whether the network address of judging certain Search Results of access is the inefficacy network address;
When the user need to check certain Search Results, browser or server judged that at first can network address corresponding to described Search Results normally access, if described network address can not normally be accessed, then the snapshots of web pages that network address is corresponding shows the user.
Generally speaking, adopt HTTP status code (HTTP Status Code) to judge the validity of network address.The HTTP status code is comprised of three tens digits, in order to success or the failure of pointing out web access requests, if the failure would indicate the causes.Five types of HTTP state code divisions are represented by its first bit digital:
3 digit numerical code with 1 beginning, comprise 100 (client should continue to send request), 101 (server has been understood the request of client, and will finish this request by the different agreement of Upgrade (upgrading) message header notice customer end adopted), 102 (by WebDAV (Web-based Distributed Authoring and Versioning, a kind of communication protocol based on HTTP 1.1 agreements) status code of expansion, representative is processed and will be continued to carry out), the expression request is accepted, need to continue to process, this class response is Temporary Response, only comprise statusline and some optional head response information, and finish with null, but owing to not defining any status code with 1 beginning in the HTTP/1.0 agreement, unless so under some test condition, server forbids sending to this type of client the response of this type of status code;
3 digit numerical code with 2 beginnings, comprise that 200 (ask successful, ask desirable head response or data volume to return with this response), 201 (ask to be implemented, and there is a new resource to set up according to the needs of request), 202 (server accepts request, but not yet process), 203 (server has successfully been processed request, but the entity head metamessage that returns is not effectively to determine set on original server, but from local or third-party copy), 204 (server has successfully been processed request, but do not need to return any entity content, and wish to return the metamessage that has upgraded), 205 (server has successfully been processed request, and do not return any content), 206 (server has successfully been processed part GET request), 207 (by the status code of WebDAV (RFC2518) expansion, message body after the representative will be an XML message), the expression request serviced device of success receives, understand, and accept;
3 digit numerical code with 3 beginnings, 300 (user or browser can select the address of a first-selection to be redirected voluntarily), 301 (requested resource forever moves to reposition, and one of any several URI (generic resource identifier) that all should use this response to return to quoting of this resource in the future), 302 (resource of request is now interim from different URI response request), 303 (response of corresponding current request can be found on another URI, and client should adopt the mode of GET to access that resource), 304 (are allowed to if client has sent GET request and this request of a SNNP, and the content of document (since last visit or according to the condition of asking) does not change, then server should return this status code), 305 (requested resource must be accessed by agency's ability of appointment), 306 (in the standard of latest edition, 306 status codes no longer are used), 307 (resource of request is now interim from different URI response request), expression needs client to take further operation just can finish request, usually, these status codes are used for being redirected, and follow-up request address (redirection target) indicates in the position field of this secondary response;
3 digit numerical code with 4 beginnings, comprise that 400 is (semantic wrong, current request can't be understood by serviced device, required parameter is wrong), 401 (current request needs user rs authentication), 402 (these status codes in the future possible demand reserve), 403 (server has been understood request, but refusal is carried out it), 404 (ask unsuccessfully, ask the desired resource that obtains not found at server), 405 (requesting method of appointment can not be used to ask corresponding resource in the request row), 406 (content character of the resource of request can't satisfy the condition in the request header, thereby can't generate the response entity), 407 is (similar with 401 responses, only client must be carried out authentication at acting server), 408 (request timed outs), 409 (because and have conflict between the current state of requested resource, request can't be finished), 410 (requested resource is no longer available on server, and without any known forwarding address), 411 (servers refusal in the situation that do not define the Content-Length head accept request), 412 (when server provides condition precedent in checking in a field of request, fail to satisfy one or more), 413 (server refusal processing current request, because the solid data size that this request is submitted to has surpassed the scope that server is ready or can be processed), 414 (the URI length of request has surpassed the length that server can be explained, therefore the server refusal provides service to this request), 415 (for method and the requested resource of current request, the entity of submitting in the request is not the form of supporting in the server, therefore request is rejected), 416 (if comprised the Range request header in the request, and any data area of appointment does not all overlap with the usable range of current resource among the Range, do not define again the If-Range request header in the request simultaneously, server just should return 416 status codes so), 417 (the expection content of appointment in request header Expect can't serviced device satisfies, perhaps this server is an acting server, it has the clear evidence proof on the next node of current route, the content of Expect can't be satisfied), 421 (maximum magnitudes that surpassed the server license from the IP address at active client place to the linking number of server), 422 (request correct formats, but owing to containing semantic error, can't respond), 424 (because the mistakes that certain request before occurs, cause the current request failure), 425 (define in WebDav Advanced Collections draft, but do not appear in " WebDAV ordered set agreement " (RFC 3658)), 426 (client should switch to TLS/1.0), 449 (are expanded by Microsoft, the representative request should be carried out retry after executing suitable operation), the expression client seems mistake may occur, and has hindered the processing of server;
3 digit numerical code with 5 beginnings, (server has run into a situation of not expected to comprise 500, caused it can't finish to the request processing), not 501 (server is not supported needed certain function of current request), 502 (when attempting carrying out request as the server of gateway or factorage, receive invalid response from upstream server), 503 (because interim server maintenance or overloads, server is current can't process request), 504 (when attempting carrying out request as the server of gateway or factorage, fail in time to receive response from upstream server), 505 (server is not supported, perhaps refusal is supported in the HTTP version that uses in the request), 506 (are expanded by " transparent content agreement protocol " (RFC 2295), there is the internal configurations mistake in representative server), 507 (server can't be stored and finish the necessary content of request), 509 (server reaches limit bandwidth), not 510 (the needed strategy of Gains resources does not satisfy), expression server wrong or abnormality in the process of processing request occurs, and also might be that server is recognized with current software and hardware resources and can't be finished processing to request.
In a preferred embodiment of the present invention, described step 103 can comprise following substep:
Substep S21: browser is sent to server with the network address of described Search Results;
Substep S22: server is resolved the generation response message to the network address of described Search Results and is returned browser;
Substep S23: the described response message of browser resolves, extract the HTTP status code of corresponding network address;
Substep S24: browser judges that according to described HTTP status code whether the network address request of access is the request of access of inefficacy network address.
In another kind of preferred embodiment of the present invention, described step 103 can comprise following substep:
Substep S31: browser is sent to server with the network address of described Search Results;
Substep S32: server is resolved the network address of described Search Results, extracts the HTTP status code in the corresponding network address;
Substep S33: server judges that according to described HTTP status code whether the network address request of access is the request of access of inefficacy network address.
As a kind of preferred exemplary of the present embodiment, status code is that 200,301,302,304 state can be considered as the state that website links success webpage is normally opened, remaining status code can be considered as losing efficacy status code of network address.
In fact, the above-mentioned mode of obtaining the HTTP status code from browser side or server side can be to generate independently thread or process is caught the HTTP status code at browser side or server side, and those skilled in the art should be appreciated that, the mode of more than obtaining the HTTP status code only is a kind of example, those skilled in the art can take other modes to realize all being fine, and the present invention is not restricted at this.
Step 106: if the network address of described Search Results is the inefficacy network address, server is searched the snapshots of web pages of coupling in database, and is back to browser.
In fact, if when browser end judges that the network address of certain Search Results of access is the inefficacy network address, the snapshots of web pages that browser is corresponding with the network address of the described Search Results request of obtaining is sent to server, and server is searched the snapshots of web pages of mating with the snapshots of web pages request of obtaining and returned browser in described snapshots of web pages database;
If when server end judged that the network address of certain Search Results of access is the inefficacy network address, server was directly searched the snapshots of web pages of mating with the snapshots of web pages request of obtaining and is returned browser from the snapshots of web pages database.
Need to prove, for embodiment of the method, for simple description, therefore it all is expressed as a series of combination of actions, but those skilled in the art should know, the present invention is not subjected to the restriction of described sequence of movement, because according to the present invention, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art also should know, the embodiment described in the instructions all belongs to preferred embodiment, and related action and module might not be that the present invention is necessary.
