使用Live HTTP标头

[英]using Live HTTP Headers

原文 2009-01-19 05:20:12 4 7 php/ curl/ http-headers/ live

On a website, I enter some parameters in a form, click on search and then get a page with a message "retrieving your results". 在网站上，我在表单中输入一些参数，单击搜索，然后获取一个页面，其中包含“检索结果”消息。 After the search is complete, I get another page with my results displayed. 搜索完成后，我会看到另一页显示我的结果。

I am trying to recreate this programatically and I used Live HTTP Headers to get a peek of what is going on behind ie the url, form variables,etc. 我试图以编程方式重新创建这个，并使用Live HTTP Headers来查看后面发生的事情，即url，表单变量等。 However, I'm only getting information of what goes on up to the page which shows "retrieving your results". 但是，我只是获取了显示“检索结果”页面的信息。 Live HTTP Header is not giving me information up to the page which contains the final results. 实时HTTP标头不会向我提供包含最终结果的页面的信息。

What can I do to get this final bit of information (ie the url, form variables, etc) 我该怎么做才能获得最后一点信息（即url，表单变量等）

I have webdeveloper installed. 我安装了webdeveloper。 Initially, I used it to turn off meta-redirects and referrers to get a clearer picture of the http interaction. 最初，我用它来关闭元重定向和引用来更清楚地了解http交互。 But when i do this, the website does not work (ie it is not able to complete the process of retrieving my search results) so i turned it back on. 但是当我这样做时，网站不起作用（即它无法完成检索我的搜索结果的过程），所以我重新开启了它。

I'm wondering if anyone has had to capture http information for a site that has a processing page in between the user input page and the results page 我想知道是否有人必须捕获在用户输入页面和结果页面之间有处理页面的站点的http信息

我对这些问题总是激发一个Ethereal或类似的网络间谍工具，以确切地看到，发生了什么。

The document is creating a browser component called XMLHTTPRequest , on submit event the object method send() is called, during the waiting time for server response an html element is replaced with a "Waiting message" on succesfull response a callback is called with the new html elements and then inserted in the selected html element. 该文档正在创建一个名为XMLHTTPRequest的浏览器组件，在提交事件中调用对象方法send（），在服务器响应的等待时间内，在成功响应时用“等待消息”替换html元素，使用new调用回调html元素然后插入选定的html元素。 (That's called ajax). （那叫做ajax）。
