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

$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。

//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;

}

}

?>
