php实现模拟post请求用法实例

本文实例讲述了php实现模拟post请求的方法。分享给大家供大家参考。具体如下：

class Request{

public static function post($url, $post_data = '', $timeout = 5){//curl

$ch = curl_init();

curl_setopt ($ch, CURLOPT_URL, $url);

curl_setopt ($ch, CURLOPT_POST, 1);

if($post_data != ''){

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

}

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

curl_setopt($ch, CURLOPT_HEADER, false);

$file_contents = curl_exec($ch);

curl_close($ch);

return $file_contents;

}

public static function post2($url, $data=array()){//file_get_content

$postdata = http_build_query(

$data

);

$opts = array('http' =>

array(

'method' => 'POST',

'header' => 'Content-type: application/x-www-form-urlencoded',

'content' => $postdata

)

);

$context = stream_context_create($opts);

$result = file_get_contents($url, false, $context);

return $result;

}

public static function post3($host,$path,$query,$others=''){//fsocket

$post="POST $path HTTP/1.1/r/nHost: $host/r/n";

$post.="Content-type: application/x-www-form-";

$post.="urlencoded/r/n${others}";

$post.="User-Agent: Mozilla 4.0/r/nContent-length: ";

$post.=strlen($query)."/r/nConnection: close/r/n/r/n$query";

$h=fsockopen($host,80);

fwrite($h,$post);

for($a=0,$r='';!$a;){

$b=fread($h,8192);

$r.=$b;

$a=(($b=='')?1:0);

}

fclose($h);

return $r;

}

}

$url='http://******/con/Inter.php';

$data=Request::post($url,array('api'=>'tag_list'));

$data2=Request::post2($url,array('api'=>'tag_list'));

echo $data;

希望本文所述对大家的php程序设计有所帮助。
