php curl返回http_code 404内容，浏览器没关系

Question

我想使用php / curl函数废弃此页面以获取产品信息。

http://www.easymall.my/flower/item-636507.html

但是，curl会返回http_code = 404，但浏览器没问题。从类似的主题，我在代码中设置了header，cookie和referer，仍然有http_code 404。

网页在Firefox下正常运行，但Firebug也表示404。

这里可能出现什么问题???

<?php
 $cookie_file = './cookie.txt';
 $url = "http://www.easymall.my/flower/item-636507.html";

 $ch = curl_init ( $url );
 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
 curl_setopt($ch, CURLOPT_MAXREDIRS, 5);   
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

 $User_Agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9) Gecko/2008052906    Firefox/3.0';      
 $request_headers = array();
 $request_headers[] = 'User-Agent: '. $User_Agent;
 $request_headers[] = 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
 curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
 curl_setopt ( $ch, CURLOPT_AUTOREFERER, true );     
 curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
 curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);

 curl_exec ( $ch );
 var_dump ( curl_getinfo ( $ch ) );
 if (curl_errno ( $ch )) {
  print curl_error ( $ch );
  } else {
  curl_close ( $ch );
  }
 ?>


array(22) { ["url"]=> string(46) "http://www.easymall.my/flower/item-636507.html"

问题不在于您的curl回复。它与网站有关。它正在发送一个404标题，如果您查看开发者控制台的网络标签，就可以看到它。

您正在抓取的网站（^{this one}）正在发送您的404。由他们来解决他们的问题，不是你的代码导致它。

网站配置错误。该网站通过.htaccess或http_response_code(404)甚至header()发送404。在不知道代码库是什么样的情况下，我无法告诉你为什么它会给你一个404，但如果它给你带来了很多错误，你应该与他们联系并让他们知道。
