php模擬post行為代碼總結(jié)(POST方式不是絕對(duì)安全）

更新時(shí)間：2012年02月22日 21:11:56 作者：

GET行為比較簡(jiǎn)單，POST比較復(fù)雜一些

這里提供兩種方法供選擇：第一：手寫(xiě)代碼。第二：利用HttpClient php類庫(kù)
　　第一種方法：

 
<？PHP 
$flag = 0; 
//要post的數(shù)據(jù) 
$argv = array( 
'var1'=>'abc', 
'var2'=>'你好嗎'); 
//構(gòu)造要post的字符串 
foreach ($argv as $key=>$value) { 
if ($flag!=0) { 
$params .= "&"; 
$flag = 1; 
} 
$params.= $key."="; $params.= urlencode($value); 
$flag = 1; 
} 
$length = strlen($params); 
//創(chuàng)建socket連接 
$fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."--->".$errno); 
//構(gòu)造post請(qǐng)求的頭 
$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 .= $params.""; 
//發(fā)送post的數(shù)據(jù) 
fputs($fp,$header); 
$inheader = 1; 
while (!feof($fp)) { 
$line = fgets($fp,1024); //去除請(qǐng)求包的頭只顯示頁(yè)面的返回?cái)?shù)據(jù) 
if ($inheader && ($line == "n" || $line == "")) { 
$inheader = 0; 
} 
if ($inheader == 0) { 
echo $line; 
} 
} 
fclose($fp); 
?> 

　　第二種方法是：使用httpclient類

復(fù)制代碼代碼如下:

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

　　使用httpclient類庫(kù)，可以去官方下載最新的類庫(kù)，官方地址為：http://scripts.incutio.com/httpclient/index.php
　　附加一些點(diǎn)php httpclient的其他幾個(gè)用法
　　靜態(tài)方法獲取網(wǎng)頁(yè)：

復(fù)制代碼代碼如下:

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

　　Get方法獲取

復(fù)制代碼代碼如下:

 
$client = new HttpClient('bankcha.com'); 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
　　帶調(diào)試的Get方法獲取 
　　PHP代碼 
$client = new HttpClient('bankcha.com'); 
$client->setDebug(true); 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
　　帶自動(dòng)轉(zhuǎn)向的Get方法 
　　PHP代碼 
　　$client = new HttpClient('www.bankcha.com'); 
$client->setDebug(true); 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
　　檢查頁(yè)面是否存在 
　　PHP代碼 
$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(); 
　　偽造客戶端 
　　PHP代碼 
$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(); 
　　登錄驗(yàn)證并請(qǐng)求一個(gè)網(wǎng)頁(yè) 
　　PHP代碼 
$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授權(quán) 
　　PHP代碼 
$client = new HttpClient('bankcha.com'); 
$client->setAuthorization('Username', 'Password'); 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
　　輸出頭信息 
　　PHP代碼 
$client = new HttpClient('bankcha.com'); 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
print_r($client->getHeaders()); 
　　設(shè)置一個(gè)域內(nèi)重定向最多次數(shù) 
　　PHP代碼 
$client = new HttpClient('www.bankcha.com'); 
$client->setDebug(true); 
$client->setMaxRedirects(3); 
$client->get('/'); 

php fsockopen 偽造 post和get方法
fsockopen 偽造 post和get方法哦，如果你正在找偽造 post和get方法的php處理代碼這款不錯(cuò)哦。

復(fù)制代碼代碼如下:

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