CURL执行返回空响应并显示

Question

我在我的项目中使用CURL,它在本地工作正常但如果我使用相同的代码它没有执行,我试图调试它.输出如下:

Took 0 seconds to send a request to https://www.google.co.in

我使用了以下示例代码:

$handle=curl_init('https://www.google.co.in');
curl_setopt($handle, CURLOPT_VERBOSE, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
$content = curl_exec($handle);

if(!curl_errno($handle))
{
    $info = curl_getinfo($handle);

    echo '<br/> Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
}
else
{
    echo 'Curl error: ' . curl_error($handle);
}

echo $content;

问题在服务器中,我不知道在php.ini中启用什么.

请注意,在服务器中,CURL和SSL已启用.如果有人遇到类似的问题,请分享解决方案.

Answer 1

在这种情况下对我来说,问题是我得到了302重定向而不是实际的get请求.

开机后CURLOPT_VERBOSE从这个答案

$fp = fopen(dirname(__FILE__).'/errorlog.txt', 'w');
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $fp);

我得到以下内容errorlog.txt:

* Connected to www.example.com (X.X.X.X) port 443 (#0)
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs

NB

1. HTTP/1.1 302 Found (应该是200响应)
2. Location: https://www.example.com/other/url/与GET请求URL 不同

问题：

功能curl_exec被禁用。该怎么办？

\n

解决方案：

\n

为了消除此错误消息，您需要执行以下操作之一：

\n

\n
1. curl_exec从文件disable_functions中删除字符串php.ini
\n
2. 如果您没有\xe2\x80\x99t 访问该php.ini文件的权限，请要求您的托管提供商删除上面的字符串
\n
3. 将托管提供商更改为允许运行该curl_exec功能的托管提供商。
\n

\n

这是 中的条目示例php.ini。

\n

更改自：

\n

disable_functions = exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,show_source,eval,posix_getpwuid

\n

到：

\n

disable_functions = exec,passthru,shell_exec,system,proc_open,popen,curl_multi_exec,show_source,eval,posix_getpwuid
