cURL错误：无法解析主机

Question

一个类似的问题已发布在，但我在那里找不到解决方案。Curl错误无法解析主机：saved_report.xml; 没有请求类型的数据记录”

<?php

$url="http://en.wikipedia.org/wiki/Pakistan";
 $ch = curl_init(urlencode($url));
  echo $ch;
  // used to spoof that coming from a real browser so we don't get blocked by some sites
  $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_USERAGENT, $useragent);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 4);
  curl_setopt($ch, CURLOPT_TIMEOUT, 8);
  curl_setopt($ch, CURLOPT_LOW_SPEED_TIME, 10);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

  $content = curl_exec($ch);



  $info = curl_getinfo($ch);

if ($content === false || $info['http_code'] != 200) {
  $content = "No cURL data returned for $url [". $info['http_code']. "]";
  if (curl_error($ch))
    $content .= "\n". curl_error($ch);
  }
else {
  // 'OK' status; format $output data if necessary here:
  echo "...";
}
  echo $content;
  curl_close($ch);
?>

当我在浏览器中粘贴相同的地址时，我可以访问该网页。 但是当我运行此脚本时，我得到了错误消息。 谁能帮帮我吗。 谢谢

Answer 1

删除urlencode调用。

Answer 2

删除urlencode($url)应该是：

 $ch = curl_init($url);

Answer 3

好。

如果您通过实例化$ch -var删除urlencode() ，就可以了。 urlencode()在这里肯定是错误的。

好：

 $ch = curl_init($url);

坏：

 $ch = curl_init(urlencode($url));

Answer 4

$ch = curl_init($url);

代替

$ch = curl_init(urlencode($url));
