php模拟post行为代码总结

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 == " " || $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://example.com/);

Get方法获取

PHP代码
$client = new HttpClient(example.com);
if (!$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(example.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.amazon.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(example.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(exa
