php模拟post行为代码总结(POST方式不是绝对安全）_php技巧

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：

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

　　第二种方法是：使用httpclient类

 <BR>$pageContents = HttpClient::quickPost('http://example.com/someForm', array( <BR>'name' => 'Some Name', <BR>'email' => '[email protected]' <BR>)); <BR>

　　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：

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

　　Get方法获取

 <BR>$client = new HttpClient('bankcha.com'); <BR>if (!$client->get('/')) { <BR>die('An error occurred: '.$client->getError()); <BR>} <BR>$pageContents = $client->getContent(); <BR>　　带调试的Get方法获取 <BR>　　PHP代码 <BR>$client = new HttpClient('bankcha.com'); <BR>$client->setDebug(true); <BR>if (!$client->get('/')) { <BR>die('An error occurred: '.$client->getError()); <BR>} <BR>$pageContents = $client->getContent(); <BR>　　带自动转向的Get方法 <BR>　　PHP代码 <BR>　　$client = new HttpClient('www.bankcha.com'); <BR>$client->setDebug(true); <BR>if (!$client->get('/')) { <BR>die('An error occurred: '.$client->getError()); <BR>} <BR>$pageContents = $client->getContent(); <BR>　　检查页面是否存在 <BR>　　PHP代码 <BR>$client = new HttpClient('bankcha.com'); <BR>$client->setDebug(true); <BR>if (!$client->g<div>本文#来源gaodai.ma#com搞##代!^码7网</div><pre>搞代gaodaima码

et(‘/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。

 <BR><?php <BR>//fsocket模拟post提交 <BR>$purl = "http://localhost/netphp/test2.php?uu=rrrrrrrrrrrr"; <BR>print_r(parse_url($url)); <BR>sock_post($purl,"uu=55555555555555555"); <BR>//fsocket模拟get提交 <BR>function sock_get($url, $query) <BR>{ <BR>$info = parse_url($url); <BR>$fp = fsockopen($info["host"], 80, $errno, $errstr, 3); <BR>$head = "GET ".$info['path']."?".$info["query"]."
