php模拟POST请求的两种方法

来源：互联网发布：js判断是否为质数编辑：程序博客网时间：2024/06/05 05:56

通过fsockopen函数

<?php
//模拟发送POST请求
$url = "http://localhost/Post/server.php";//要请求的服务器地址

//要请求的内容
$post_data['user']       =   "root";
$post_data['password']   =    "1988725";

//转换请求内容
foreach($post_data as $key => $value)
{
   $requestArray[] = $key.'='.urlencode($value);
}
$requestString   =   implode("&",$requestArray);

//url
$url_info   =   parse_url($url);

if(!isset($url_info['port']))
{
   $url_info['port']   =   80;
   //模拟http请求头
   $request   .=   "POST ".$url_info['path']." HTTP/1.1\n";
   $request   .=   "Host: ".$url_info['host']."\n";
   $request   .=   "Content-type: application/x-www-form-urlencoded\n";
    $request   .=   "Content-length: ".strlen($requestString)."\n";
   $request   .=   "Connection: close\n";
    $request   .=   "\n";
   $request   .=   $requestString."\n";
}

$fp = fsockopen($url_info["host"], $url_info["port"]);
fputs($fp, $request);//把HTTP头发送出去

$inheader = 1;
while(!feof($fp))
{
   //$result 是提交后返回的数据
   $result .= fgets($fp, 1024);
}
echo $result;
fclose($fp);

通过 crul

<?php
//要请求的内容
$post_data['user']       =   "root";
//$post_data['password']   =    "1988725";
$post_data['file']       =   '@C:\Documents and Settings\chenzhi\My Documents\My Pictures\1286606098_38.jpg';

///$post_data['file']   =    '@'.$_FILES['image']['tmp_name'];
$ch       =   curl_init();
$curl_url   =   "http://172.16.27.51/server.php";
curl_setopt($ch,CURLOPT_URL,$curl_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//不直接输出，返回到变量
//$curl_result = curl_exec($ch);
//echo $curl_result;

curl_exec($ch);

注意，通过curl传送图片时，一定要记住要加@号，且不能用双引号，只能用单引号
