我想让 PHP 请求 GET 异步,但是我的 PHP 版本是 5.2.13,curl 的版本是 7.16.4,有很多限制。
我试过了:
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
但它不起作用。据我所知,这仅适用于 PHP 5.2.3
所以我阅读了另一个解决方案 fsockopen:
function curl_request_async($url, $params, $type='POST')
{
if (count($params)>0){
$post_params = array();
foreach ($params as $key => &$val) {
if (is_array($val)) $val = implode(',', $val);
$post_params[] = $key.'='.urlencode($val);
}
$post_string = implode('&', $post_params);
}
$parts = parse_url($url);
$fp = fsockopen($parts['host'],
isset($parts['port'])?$parts['port']:80,
$errno, $errstr, 30);
// Data goes in the path for a GET request
if(('GET' == $type)&& isset($post_string)) $parts['path'] .= '?'.$post_string;
$out = "$type ".$parts['path']." HTTP/1.1\r\n";
$out.= "Host: ".$parts['host']."\r\n";
$out.= "Content-Type: application/x-www-form-urlencoded\r\n";
$out.= "Content-Length: ".strlen($post_string)."\r\n";
$out.= "Connection: Close\r\n\r\n";
// Data goes in the request body for a POST request
if ('POST' == $type && isset($post_string)) $out.= $post_string;
fwrite($fp, $out);
fclose($fp);
}
适用于 POST 但不适用于 GET。我想让请求 GET 异步
任何人都可以帮助我吗?
太感谢了
