cURL connect()超时

Question

在过去的几个月里,我的cURL实现成功运行,没有打嗝; 然而,上周我突然开始遇到一个特定网站(www.viewmag.com)的问题.我可以在浏览器中完美地访问该网站(并让它解决),但cURL会返回以下内容:

* About to connect() to www.viewmag.com port 80 (#0)
*   Trying 205.178.145.65... * Timeout
* connect() timed out!
* Closing connection #0

为了理智,我试图用两个不同的盒子ping网站,但每次ping都超时了.

方框1(Linux):

ping www.viewmag.com
PING www.viewmag.com (205.178.145.65) 56(84) bytes of data.

方框2(Windows):

ping www.viewmag.com

Pinging www.viewmag.com [205.178.145.65] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

我的cURL如下:

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, 'http://www.viewmag.com');
curl_setopt ($ch, CURLOPT_USERAGENT, 'cURL crawler');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_AUTOREFERER, true);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 2);
$html = curl_exec($ch);

有没有人想到为什么cURL失败以及为什么我能够在浏览器中访问这个网站,但却无法ping/cURL呢？提前致谢

Answer 1

1. 也许您的服务器IP在该网站上被禁止？

2. 也许尝试设置更长的超时？我访问了该网站,它的工作速度很慢,您可能需要超过5秒钟.

后来添加:

看起来您的服务器IP被禁止.

我试过这个(它的代码副本,更改在注释中):

<?php

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, 'http://www.viewmag.com');

// I changed UA here
curl_setopt ($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1');

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_AUTOREFERER, true);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 2);
$html = curl_exec($ch);

// I added this 
echo $html; 

?>

它适用于我的测试服务器(德国的数据中心).
