跨域-检索页面源 [英] CROSS-DOMAIN - Retrieve Page Source
问题描述
我在这里有一个项目正在工作，我们需要另一个域的特定值，但我无权更改(因此，我无法嵌套iframe或CORS).我们需要保持Session/Cookie状态不变，以根据令牌在页面上的用户变化来从页面获取所需的数据.因此，服务器端解决方案将无法正常工作.
Hi I have a project here at work where we need a specific value from another domain I do not have access to change (So I can't do nested iframes, or CORS). We need to keep Session/Cookie state the same to get the required data from the page as the token changes based on the user on the page. So a server side solution wouldn't work.
解决此问题的最佳方法是什么，以下是页面源代码的全部内容. 我需要检索FF321332值
What is the best way to go about this, the following is what the page source is in it's entirety. I need to retrieve the FF321332 value
{"<!--":"","token":"FF321332","expire":1317448445,"":"--><body onload=document.body.innerHTML=clear>"}
到目前为止，我尝试过的一些事情是动态脚本标签"它引发JS错误意外令牌:错误，jQuery(.getScript)引发相同错误，任何其他形式的.get或xhr都会引发跨域错误错误.
Some things I've tried so far are Dynamic Script Tags "It throws a JS error Unexpected token : error, Jquery (.getScript ) this throws the same error, any other form of .get or xhr will throw a Cross Domain Error.
我感觉自己在使用.getScript或Dynamic Script标签的正确轨道上，因为它几乎想读入它.但是，如果我能解决Unexpected token错误并以文本形式读入(如果是的话)可能)我可以将变量解析为普通文本.
I feel like I was on the right track with the .getScript or Dynamic Script Tags as it almost wants to read it in. But if I can get around the Unexpected token error and just read it in as text (if this is possible) I can just parse out the variable as normal text.
在此方面的任何帮助将不胜感激.
Any assistance in this would be greatly appreciated.
推荐答案
JSONP允许您执行您想做的事情.查看有关如何使.get使用JSONP来避免浏览器跨域强制实施的jQuery文档.
JSONP allows you to do what you are trying to do. Check out the jQuery doc on how to make your .get use JSONP to side step the browser cross-domain enforcement.
本质上，当您执行$ .getJSON时，如果url中有一个写着"callback ="+的内容"，那么它将把它视为jsonp而不是标准的getjson.
Essentially, when you do $.getJSON, if the url has a piece that says "callback=" + whatever, then it will treat it as jsonp instead of the standard getjson.
祝你好运.
