PHP HTTP GET POST

一.来源1: http://www.cnblogs.com/chenshaoyi/archive/2012/01/12/2320729.html

-------------------------------------------------

PHP有三种方法可以模拟POST提交,分别为curl、socket、file_get_contents

curl方式：（我目前用的是这种）

/**
* Curl版本
* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_curl(‘http://facebook.cn/restServer.php‘,$post_string);
*/
function request_by_curl($remote_server,$post_string){
   $ch = curl_init();
   curl_setopt($ch,CURLOPT_URL,$remote_server);
   curl_setopt($ch,CURLOPT_POSTFIELDS,$post_string);
   curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
   $data = curl_exec($ch);
   curl_close($ch);
   return $data;
}

socket方式：

/**
* Socket版本
* 使用方法：
* $post_string = "app=socket&version=beta";
* request_by_socket(‘facebook.cn‘,‘/restServer.php‘,$post_string);
*/
function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30){
   $socket = fsockopen($remote_server,$port,$errno,$errstr,$timeout);
   if (!$socket) die("$errstr($errno)");

   fwrite($socket,"POST $remote_path HTTP/1.0\r\n");
   fwrite($socket,"User-Agent: Socket Example\r\n");
   fwrite($socket,"HOST: $remote_server\r\n");
   fwrite($socket,"Content-type: application/x-www-form-      urlencoded\r\n");
   fwrite($socket,"Content-length: ".strlen($post_string)+8."\r\n");
   fwrite($socket,"Accept:*/*\r\n");
   fwrite($socket,"\r\n");
   fwrite($socket,"mypost=$post_string\r\n");
   fwrite($socket,"\r\n");

   $header = "";
   while ($str = trim(fgets($socket,4096))) {
      $header.=$str;
   }

   $data = "";
   while (!feof($socket)) {
      $data .= fgets($socket,4096);
   }

   return $data;
}

file_get_contents方式：

/**
* file_get_contents版本
* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_other(‘http://facebook.cn/restServer.php‘,$post_string);
*/
function request_by_other($remote_server,$post_string){
   $context = array(
      ‘http‘=>array(
         ‘method‘=>‘POST‘,
         ‘header‘=>‘Content-type: application/x-www-form-urlencoded‘."\r\n".
         ‘User-Agent : Jimmy\’s POST Example beta‘."\r\n".
         ‘Content-length: ‘.strlen($post_string)+8,
         ‘content‘=>‘mypost=‘.$post_string)
      );
   $stream_context = stream_context_create($context);
   $data = file_get_contents($remote_server,FALSE,$stream_context);
   return $data;
}

方法三：这个要借助第三方类库HttpClient可以到这里下载：http://scripts.incutio.com/httpclient/＜?php
require_once
‘HttpClient.class.php’;
$params = array(’web’ =＞ ’www.baidu.com’,
’pwd’ =＞
’123456’,
’action’ =＞ ’check’,
’pseid’ =＞ ’NDE005’,
’amt’ =＞
1);
$pageContents =
HttpClient::quickPost(’http://localhost:81/flandy/getpost3.php’,
$params);
$result = explode(’,’,
$pageContents);
print_r($result);
