CURL execution returns empty response and shows

提问by AnNaMaLaI

I am using CURL in my project, Its working fine locally but if i use the same code its not executing, I tried to debug it. The output as follows :

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，我尝试调试它。输出如下：

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

I used the following sample code:

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;

The Problem is in server, I don't know what to enable in php.ini.

问题出在服务器上，我不知道在 php.ini 中启用什么。

Please note that in server CURL and SSL is enabled. If anyone faced similar problems, share solutions please.

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

PROBLEM:

Function curl_execis disabled. What to do?

SOLUTION:

In order to eliminate this error message you need to do oneof the following things:

1. Remove the curl_execstring from the disable_functionsin the php.inifile
2. Ask your hosting provider to remove the string above if you don't have an access to the php.inifile
3. Change hosting provider to one which allows the running of the curl_execfunction.

Here is an example of the entry in php.ini.

Change from:

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

To:

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

问题：

功能curl_exec被禁用。该怎么办？

解决方案：

为了消除你需要做此错误消息一个下面的事情：

1. 删除curl_exec从字符串disable_functions中php.ini的文件
2. 如果您无权访问该php.ini文件，请要求您的托管服务提供商删除上述字符串
3. 将主机提供商更改为允许运行该curl_exec功能的提供商。

这是 中条目的示例php.ini。

更改自：

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

到：

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

For me in this case, the problem was that I was getting a 302 redirect rather than the actual get request.

在这种情况下，对我来说，问题是我收到的是 302 重定向而不是实际的 get 请求。

After turning on CURLOPT_VERBOSEfrom this answer

CURLOPT_VERBOSE从这个答案开启后

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

I got the following in the errorlog.txt:

我在以下内容中得到了errorlog.txt：

N.B.

NB

1. HTTP/1.1 302 Found(should just be a 200 response)
2. Location: https://www.example.com/other/url/is different from the GETrequest URL

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