$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy); // $proxy is ip of proxy server
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time
echo '<br> curl'.$ch; //this line outputs resource id#5
$exec = stripslashes(curl_exec($ch));
echo '<br> exec'.curl_exec($ch); //this results blank
i am confused why $exec does not return anything ,i am new to curl please help, thanks in advance
curl_exec will return false
when the request failed. Adjust your function to this :
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy); // $proxy is ip of proxy server
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time
$response = curl_exec($ch);
if ($response === false)
$response = curl_error($ch);
echo stripslashes($response);
curl_close($ch);
This way u'll see the curl error
结果返回0表示您无法连接到服务器,因此请重新检查您的代理并增加超时:)
You're trying to access a HTTP response code before you actually make the HTTP call. Reverse the execution as follows:
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time
Try:
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
Maybe the response is longer than 10.
I had the same issue, I solved like this.
