如何通过 cfhttp 模拟真实的 http 请求?

问题描述

我需要通过 cfhttp 模拟一个真实的 http 请求.我正在使用 ColdFusion 获取 rss 提要，但今晚他们开始阻止我的请求并发送一个索引页面作为响应，而不是 rss 提要.

I need to emulate a real http request via cfhttp.I was getting rss feed with ColdFusion, but tonight they started to block my request and send an index page in response instead of rss fead.

我为 cfhttp 添加了用户代理，但没有帮助.

I added useragent for cfhttp, but it doesn't help.

Opera、Firefox 和 Chrome 从同一台计算机正确打开提要.

Opera, Firefox and Chrome open feed correctly from the same computer.

推荐答案

好的，谢谢.我嗅探了浏览器发送到站点的所有 HTTP 标头，然后在 cfhttp 请求中模拟它们.解决办法是:

Yep, thanks. I sniffed all HTTP headers which browser sends to the site and then emulated them in cfhttp request. The solution is:

<cfhttp url="http://example.com/feed"
useragent="Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.7 (KHTML, like Gecko) Chrome/5.0.391.0 Safari/533.7"
result="httpresult"
redirect="false"
>
<cfhttpparam type="header" name="HTTP_REFERER" value="http://example.com/feed/" >
<cfhttpparam type="header" name="Accept-Encoding" value="gzip,deflate,sdch" >
<cfhttpparam type="header" name="Proxy-Connection" value="keep-alive" >
<cfhttpparam type="header" name="Accept" value="application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5">
<cfhttpparam type="header" name="Accept-Language" value="en-US,en;q=0.8">
<cfhttpparam type="header" name="Accept-Charset" value="ISO-8859-1,utf-8;q=0.7,*;q=0.3">
<cfhttpparam type="cookie" name="some-cookie" value="1">
