php模拟post行为代码总结(POST方式不是绝对安全）

GET行为比较简单，POST比较复杂一些。这里提供两种方法供选择：第一：手写代码。第二：利用HttpClient php类库

　　第一种方法：

       PHP代码

<？PHP           
    $flag = 0;       
    //要post的数据        
$argv = array(       
     'var1'=>'abc',        
     'var2'=>'你好吗');        
//构造要post的字符串        
foreach ($argv as $key=>$value) {        
     if ($flag!=0) {       
             $params .= "&";        
             $flag = 1;        
     }        
     $params.= $key."="; $params.= urlencode($value);        
     $flag = 1;        
     }        
     $length = strlen($params);       
         //创建socket连接        
     $fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."--->".$errno);        
     //构造post请求的头        
     $header = "POST /mobile/try.php HTTP/1.1";        
     $header .= "Host:127.0.0.1";        
     $header .= "Referer:/mobile/sendpost.php";        
     $header .= "Content-Type: application/x-www-form-urlencoded";        
     $header .= "Content-Length: ".$length."";        
     $header .= "Connection: Close";       
     //添加post的字符串        
     $header .= $params."";        
     //发送post的数据        
     fputs($fp,$header);        
     $inheader = 1;        
     while (!feof($fp)) {       
             $line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据        
             if ($inheader && ($line == "n" || $line == "")) {       
                 $inheader = 0;        
             }        
             if ($inheader == 0) {        
                 echo $line;        
             }        
     }        
fclose($fp);        
?>      
 

　　第二种方法是：使用httpclient类

　　PHP代码

$pageContents = HttpClient::quickPost('http://example.com/someForm', array(       
    'name' => 'Some Name',       
    'email' => 'email@example.com'      
));   

　　使用httpclient类库，可以去官方下载最新的类库，官方地址为：http://scripts.incutio.com/httpclient/index.php

　　附加一些点php httpclient的其他几个用法

　　静态方法获取网页：

　　PHP代码

$pageContents = HttpClient::quickGet('http://bankcha.com')
 

　　Get方法获取

　　PHP代码

$client = new HttpClient('bankcha.com');       
if (!$client->get('/')) {       
    die('An error occurred: '.$client->getError());       
}       
$pageContents = $client->getContent();   
 

　　带调试的Get方法获取

　　PHP代码

$client = new HttpClient('bankcha.com');       
$client->setDebug(true);       
if (!$client->get('/')) {       
    die('An error occurred: '.$client->getError());       
}       
$pageContents = $client->getContent();     

　　带自动转向的Get方法

　　PHP代码

　　$client = new HttpClient('www.bankcha.com');       
$client->setDebug(true);       
if (!$client->get('/')) {       
    die('An error occurred: '.$client->getError());       
}       
$pageContents = $client->getContent();    

 

　　检查页面是否存在

　　PHP代码

$client = new HttpClient('bankcha.com');       
$client->setDebug(true);       
if (!$client->get('/thispagedoesnotexist')) {       
    die('An error occurred: '.$client->getError());       
}       
if ($client->getStatus() == '404') {       
    echo 'Page does not exist!';       
}       
$pageContents = $client->getContent(); 
 

　　伪造客户端

　　PHP代码

$client = new HttpClient('bankcha.com');       
$client->setDebug(true);       
$client->setUserAgent('Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021207');       
if (!$client->get('/')) {       
    die('An error occurred: '.$client->getError());       
}       
$pageContents = $client->getContent();  
 

　　登录验证并请求一个网页

　　PHP代码

$client = new HttpClient('bankcha.com');       
$client->post('/login.php', array(       
    'username' => 'Simon',       
    'password' => 'ducks'      
));       
if (!$client->get('/private.php')) {       
    die('An error occurred: '.$client->getError());       
}       
$pageContents = $client->getContent();     
 

　　HTTP授权

　　PHP代码

$client = new HttpClient('bankcha.com');       
$client->setAuthorization('Username', 'Password');       
if (!$client->get('/')) {       
    die('An error occurred: '.$client->getError());       
}       
$pageContents = $client->getContent();     

　　输出头信息

　　PHP代码

$client = new HttpClient('bankcha.com');       
if (!$client->get('/')) {       
    die('An error occurred: '.$client->getError());       
}       
print_r($client->getHeaders());     
 

　　设置一个域内重定向最多次数

　　PHP代码

$client = new HttpClient('www.bankcha.com');       
$client->setDebug(true);       
$client->setMaxRedirects(3);       
$client->get('/');

fsockopen 伪造 post和get方法哦，如果你正在找 伪造 post和get方法的php处理代码这款不错哦。

<?php
//fsocket模拟post提交
$purl = "http://localhost/netphp/test2.php?uu=rrrrrrrrrrrr";
print_r(parse_url($url));
sock_post($purl,"uu=55555555555555555");

//fsocket模拟get提交
function sock_get($url, $query)
{
   $info = parse_url($url);
   $fp = fsockopen($info["host"], 80, $errno, $errstr, 3);
   $head = "GET ".$info['path']."?".$info["query"]." HTTP/1.0rn";
   $head .= "Host: ".$info['host']."rn";
   $head .= "rn";
   $write = fputs($fp, $head);
   while (!feof($fp))
   {
    $line = fread($fp,4096);
    echo $line;
   }
}
sock_post($purl,"uu=rrrrrrrrrrrrrrrr");

function sock_post($url, $query)
{
   $info = parse_url($url);
   $fp = fsockopen($info["host"], 80, $errno, $errstr, 3);
   $head = "POST ".$info['path']."?".$info["query"]." HTTP/1.0rn";
   $head .= "Host: ".$info['host']."rn";
   $head .= "Referer: http://".$info['host'].$info['path']."rn";
   $head .= "Content-type: application/x-www-form-urlencodedrn";
   $head .= "Content-Length: ".strlen(trim($query))."rn";
   $head .= "rn";
   $head .= trim($query);
   $write = fputs($fp, $head);
   while (!feof($fp))
   {
    $line = fread($fp,4096);
    echo $line;
   }
}

?>
