CURL用旋转键提交表单 [英] CURL to submit form with rotating key

问题描述

我试图在我自己的网站上创建一个自动脚本，它登录到网站，传递一些POST头，并基本上开始导出。

I'm attempting to create an automated script on my own site which logs into the site, passes some POST Headers and essentially starts an export.

由于每个网页载入时都有不同的旋转键，因此难以通过登录页面。

However, I am having difficulty getting passed the login page since there is a rotating key that is different on every page load.

我试图运行脚本没有可用，脚本如下在顶部输出$ xid。但是如果我检查$ xid回应它不同于当前的页面上的xid值。

I have tried running the script with no avail, the script below outputs the $xid at the top. But if I check the $xid echoed it is not the same as the current xid value on the page.

编辑：好问题Norman - 这只是你简单的隐藏字段每次重新加载页面时都会更改的随机值。所以基本上看来我必须找到一个页面的xid之前的'curl_exec'ing它，我不知道如何做，或者如果它甚至可能。也许这需要一些JS和CURL。

Good question Norman - It's just your simple hidden field with a random value that changes every time the page is reloaded. So basically it seems I have to find the xid of a page before 'curl_exec'-ing it which I don't know how to do or if it's even possible. Maybe this requires some JS along with CURL.

Edit2：这是演示的示例网址

有关如何解决这个问题的任何想法？

Any ideas as to how to get around this?
