php精华：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 == "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 protected]'        ));

　　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('/');
