php模拟post行为代码总结(POST方式不是绝对安全）_PHP教程

<？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 
 代码如下:

$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： 
 代码如下:

$pageContents = HttpClient::quickGet('http://bankcha.com') 
 
　　Get方法获取 
 代码如下:

$client = new HttpClient('bankcha.com'); 
if (!$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('/'); 
 
php fsockopen 伪造 post和get方法 
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。 
 代码如下:

//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; 
} 
} 
?>
