Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Fig. 1 is the page access method according to the embodiment of the invention, may further comprise the steps:
Step S102; Gate system receives the access request from client browser; Wherein, This access request is used to ask to visit the page (being webpage) of embedded third party system, the destination address of this access request be gate system act on behalf of the URL address, and the parameter of URL address is acted on behalf of as this in the address of third party system;
For example, the address of third party system is X, is acting on behalf of the URL address /proxy.do that then the destination address of this access request is/proxy.do? _ url=X.
Step S104, gate system is transmitted to the third party system with the access request that receives;
Step S106; Gate system receives the access request response that the third party system returns; With the response of this access request be transmitted to client browser with generate by client browser the page that will visit; Wherein, the source address of this access request response is above-mentionedly to act on behalf of the URL address, and the parameter of URL address is acted on behalf of as this in the address of third party system.
Wherein, the form of source address and last example are similar.
Present embodiment is acted on behalf of the URL address through on gate system, being provided with one; When client browser visit is embedded in the page of third party system at Web interface of gate system; The parameter of URL address is acted on behalf of as this in the address of acting on behalf of URL accessed and third party system through this gate system; And also act on behalf of the parameter of URL address as this for the address that this acts on behalf of URL address and third party system in the source address of the access request that receives response; Like this, when the user operated the page of third party system through browser, browser just thought that this page is from gate system; With parent window or top-level window be same territory, therefore just can use script to visit window.parent or window.top safely.Present embodiment has solved the problem that the function that the page of third party system provides when cross-domain problem occurring in the prior art can't realize; Thereby can visit window.parent or window.top, can normally realize such as the function that shows that the third party system the floating frame etc. provides placed in the middle in top-level window.
When reality was implemented, the access request in the foregoing description can be HTTP (Hypertext Transfer Protocol, HTTP) request, and above-mentioned access request response can be http response.
When reality was implemented, the concrete realization flow of page access method was as shown in Figure 2 according to the preferred embodiment of the invention, may further comprise the steps:
Step S202; Embed the page of third party system on the Web interface of gate system with iframe (framework webpage or embedded webpage); The address of the page of embedded third party system is not the address of directly using the third party system, needs through conversion process, and what be set to gate system acts on behalf of URL (Uniform Resource Locator; URL) address, and the parameter of URL address is acted on behalf of as this in the address of third party system;
For example: the address of third party system is X, acts on behalf of the URL address to be/proxy.do.
The address of the page of so, embedded third party system can not directly be used:
<iframe?src＝″X″></iframe>；
But to convert into<iframe src＝″/proxy.do？_url＝X″></iframe>。
After step S204, gate system receive the HTTP request (message) from client browser, transmit HTTP and ask the third party system;
After step S202 accomplished, client browser will send the HTTP request to the URL address/proxy.do that acts on behalf of of gate system.
This step is corresponding to the step S102 among Fig. 1.
Step S206, gate system resolve the HTTP request that receives, and obtain the address of third party system and the request mode of client browser;
Resolving among the step S206 is accomplished following function:
(1) from the parameter of HTTP request, extracts the address of third party system;
(2) the request mode of analysis client browser is GET (obtaining) or POST (transmission) from the HTTP request;
Wherein, GET sends request to specific resource.Attention: the GET method should not be used to produce in the operation of " side effect ", for example in Web Application (application).One of them reason is that GET may be by arbitrarily visits such as crawler.
POST submits to data to handle request (for example submission form or upload file) to allocated resource, and data are comprised in the request body.The POST request may cause the establishment of new resource and/or the modification of existing resource.
(3) from the HTTP request, extract HTTP request header and other parameters.
Step S208, gate system send to the third party system according to resolving the request mode that obtains among the step S206 after this HTTP request is encapsulated again;
The request mode that gate system obtains according to parsing; Like GET or POST; Use corresponding GET or POST mode; Request header that parsing is obtained and parameter with act on behalf of the URL address and be packaged into HTTP request (putting into the request header or the parameter of HTTP request) again as acting on behalf of the URL address, this HTTP request (i.e. HTTP request after the encapsulation again) is sent in the address of in step S206, resolving the third party system that obtains again, and waits for that receiving the third party system accomplishes the http response of returning after handling (message).
Step S210, after the third party system receives the HTTP request message, the URL address on the processing page, the URL address setting that is about to use on the page is absolute address`;
Particularly, resolve the HTTP request message, from HTTP required parameter or request header, parse and act on behalf of the URL address, then, the URL address of using on the processing page.
The processing of the URL address of using on the page divides two kinds of situation:
Use absolute address` when (1) quoting static resource such as CSS file, script file, picture, as:
<link?type＝″text/css″href＝″http://abc/d.css″rel＝″stylesheet″/>；
<script?type＝″text/javascript″src＝″http://abc/e.js″></script>；
<img?src＝″http://abc/f.jpg″/>。
That is, when comprising static resource on the page, the third party system is an absolute address` with the URL address setting of static resource, and wherein, it is one of following that static resource comprises at least: quote CSS file, script file, picture.
Its reason is: if used relative address in the webpage of requested third party system; Then after http response turns back to client browser; Client browser is used the absolute address` that computational resource is come in the address of gate system; Can not go third party's system request resource with regard to having caused client browser visit gate system like this, and gate system will cause page display abnormality or dysfunction when not having the resource of needs.
For example: the picture HTML code of third party system is:
<img src＝″fjpg″/>, the address of gate system is http://ddd, then the client browser address of calculating is http://ddd/f.jpg, rather than the http://abc/f.jpg that wants.
And if the picture HTML code of third party system is <imgsrc=" http://abc/f.jpg " />, client browser will find the resource of appointment exactly.
(2) need the user to submit to or, also will use absolute address` with the URL address of ajax (Asynchronous JavaScriptand XML, asynchronous JavaScript and XML (Extension Markup Language, extend markup language)) request visit.That is, when comprising on the page that the URL address of ajax request visit is perhaps used in the URL address that needs client browser to submit to, the URL address setting that the URL address that the third party system will submit to or this use the ajax request to visit is absolute address`.
Simultaneously; Change the URL address of acting on behalf of that also need use parsing to obtain, and is X like raw address, and acting on behalf of the URL address is Y; Need convert Y into? The form of _ url=X; That is, the third party system converts the absolute address` of using into this and acts on behalf of the URL address, and this absolute address` is acted on behalf of the parameter of URL address as this.
Its reason is: does not change the user URL address of submitting to if desired, and then the user can directly be submitted to the third party system, has so just left gate system, if rethink visit window.parent or window.top, can cause cross-domain problem equally; If does not change the URL address of ajax request, also can cause cross-domain problem, cause client browser to stop, and then the function that makes the third party system provide is invalid, or even reports an error.
Step S212, webpage (page) is through after the above-mentioned processing, and the page after the third party system will handle is carried at and sends to gate system in the http response;
Step S214, gate system receive the http response message after the above-mentioned processing of process that the third party system sends back, return to client browser and generate the final Web page.
Fig. 3 is the page access system according to the embodiment of the invention, comprising: the third party system 20 on gate system 10 and the Web interface that is embedded in gate system 10, and wherein, gate system 10 comprises:
First sending module 104; Be used for the access request that receiver module 102 receives is transmitted to third party system 20; And access request response is transmitted to client browser 30; Wherein, the source address of this access request response is for acting on behalf of the URL address, and the parameter of URL address is acted on behalf of as this in the address of third party system 20.
Wherein, Third party system 20 is embedded on the Web interface of gate system 10 with the mode of iframe, wherein, and when embedded; The address setting of the page of third party system 20 is above-mentionedly to act on behalf of the URL address, and the parameter of URL address is acted on behalf of as this in the address of third party system 20.
For example: the address of third party system 20 is X, acts on behalf of the URL address to be/proxy.do.
The address of the page of so, embedded third party system 20 can not directly be used:
<iframe?src＝″X″></iframe>；
And should use<iframe src＝″/proxy.do？_url＝X″></iframe>
