cURL connect（）超时 [英] cURL connect() timed out

问题描述

我的cURL实现在过去几个月没有打嗝的情况下成功运行;然而，上周我突然开始有一个特定的网站（www.viewmag.com）的问题。我可以在浏览器中完美地访问网站（并让它解决），但cURL返回以下内容：

  （）到www.viewmag.com端口80（＃0）
 *尝试205.178.145.65 ... *超时
 * connect（）超时！ 
 *正在关闭连接＃0 
  

Box 1（Linux）：

  ping www.viewmag.com 
 PING www.viewmag.com（205.178.145.65）56（84）字节的数据。 
  

方块2（Windows）：

  ping www.viewmag.com 
 
 Pinging www.viewmag.com [205.178.145.65]带32字节数据：
请求超时。 
请求超时。 
请求超时。 
请求超时。 
  

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）; 
  

有没有人对cURL为什么会失败以及为什么我会访问这个网站有任何想法在浏览器中，但是不能ping / cURL呢？提前感谢

解决方案

1. 也许您的服务器IP被禁止在该网站上？ p>




2. 也许尝试设置更长的超时时间？我访问了该网站，运行缓慢，可能需要5秒以上。

稍后添加：

看起来您的服务器IP已被禁止。

我试过这个（它的代码的副本，更改是在评论）：

 <？php 
 
 $ ch = curl_init（）; 
 curl_setopt（$ ch，CURLOPT_URL，'http://www.viewmag.com'）; 
 
 //我改变了UA这里
 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）; 
 
 //我添加了这个$​​ b $ b echo $ html; 
 
？> 
  

，它在我的测试服务器（德国的数据中心）上工作。

I've had my cURL implementation running successfully for the last few months without hiccups; however, last week I suddenly started to have a problem with one specific website (www.viewmag.com). I can visit the site (and have it resolve) perfectly in a browser, but cURL returns the following:

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

For sanity, I tried to ping the website with two different boxes, but each ping timed out.

Box 1 (Linux):

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

Box 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.

My cURL is as follows:

$ch = curl_init();
curl_setopt ($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);

Does anyone have any thoughts as to why cURL is failing and why I would be able to visit this site in a browser, but not be able to ping/cURL it? Thanks in advance

解决方案

1. Maybe your server IP is banned on that site?

2. Maybe try to set longer timeout? I visited that site and it works so slow, that you may need more than 5 seconds.

Added later:

Looks like your server IP is banned.

I tried this (its copy of your code, changes are in comments):

<?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; 

?>

and it works on my test server (data center in Germany).
