卷曲错误：操作超时

Question

I have the following fatal error when trying to use Curl:

PHP Fatal error:  Uncaught HTTP_Request2_MessageException: 
Curl error: Operation timed out after 30000 milliseconds with 0 bytes received in      
/usr/share/php/HTTP/Request2/Adapter/Curl.php on line 200
Exception trace    Function       Location
0                  HTTP_Request2_Adapter_Curl::wrapCurlError('Resource id #12') 
                   /usr/share/php/HTTP/Request2/Adapter/Curl.php:200
1                  HTTP_Request2_Adapter_Curl->sendRequest(Object(HTTP_Request2))
/usr/share/php/HTTP/Request2.php:959< in /usr/share/php/HTTP/Request2/Adapter/Curl.php on line 172

However, I can't see how to best debug it. There's no reference to any line of code I've written, only the HTTP_Request2 and Curl modules. What's the best approach to try and resolve this?

Answer 1

Your curl gets timed out. Probably the url you are trying that requires more that 30 seconds.

If you are running the script through browser, then set the set_time_limit to zero for infinite seconds.

set_time_limit(0);

Increase the curl's operation time limit using this option CURLOPT_TIMEOUT

curl_setopt($ch, CURLOPT_TIMEOUT,500); // 500 seconds

It can also happen for infinite redirection from the server. To halt this try to run the script with follow location disabled.

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);

Answer 2

Some time this error in Joomla appear because some thing incorrect with SESSION or coockie. That may because incorrect HTTPd server setting or because some before CURL or Server http requests

so PHP code like:

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
  curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

will need replace to PHP code

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
//curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
//curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); // !!!!!!!!!!!!!
  //if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

May be some body reply how this options connected with "Curl error: Operation timed out after .."

I got same problem lot of time. Check your request url, if you are requesting on local server like 127.1.1/api or 192.168.... , try to change it, make sure you are hitting cloud.

Answer 4

$curl = curl_init();

  curl_setopt_array($curl, array(
  CURLOPT_URL => "", // Server Path
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 3000, // increase this
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\"email\":\"DarylBrowng@gmail.coh\",\"password\":\"markus William\",\"username\":\"Daryl Brown\",\"mobile\":\"013132131112\","msg":"No more SSRIs." }",
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json",
    "Postman-Token: 4867c7a3-2b3d-4e9a-9791-ed6dedb046b1",
    "cache-control: no-cache"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

initialize array index "CURLOPT_TIMEOUT" with a value in seconds according to time required for response .

Answer 5

在 curl 请求中添加超时 0，因此其无限时间设置为 CURLOPT_TIMEOUT 设置 0
