本文实例讲述了PHP模拟http请求的方法。分享给大家供大家参考，具体如下：

方法一：利用php的socket编程来直接给接口发送数据来模拟post的操作。

建立两个文件post.php,getpost.php

post.php内容如下：

<?php $flag = 0; $params = ''; $errno = ''; $errstr = ''; //要post的数据 $argv = array( 'var1'=>'abc', 'var2'=>'how are you , my friend??'); //构造要post的字符串 foreach ($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 $fp = fsockopen("localhost",81,$errno,$errstr,10) or exit($errstr."--->".$errno); //构造post请求的头 $header = "POST /flandy/getpost.php HTTP/1.1rn"; $header .= "Host:127.0.0.1rn"; $header .= "Referer:/flandy/post.phprn"; $header .= "Content-Type: application/x-www-form-urlencodedrn"; $header .= "Content-Length: ".$length."rn"; $header .= "Connection: Closernrn"; //添加post的字符串 $header .= $params."rn"; //发送post的数据 fputs($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 == "rn")) { $inheader = 0; } if ($inheader == 0) { echo $line; } } fclose($fp); ?>

getpost.php的内容如下:

<"this is the data posted"; echo "<pre>"; print_r($_REQUEST); echo "</pre>"; ?>

结果输出：

this is the data posted Array ( [var1] => abc [var2] => how are you , my friend?? )

以上代码在本机81端口下已经通过测试。

方法二：使用PHP的curl扩展或HttpClient.class.php类，这两个非常类似，下面简单的列出curl的实现代码。

两个文件post2.php和getpost2.php

post2.php的内容如下：

<?php $psecode = 'NDE005'; $website = 'www.baidu.com'; $amt = 1; $pwd = 123456; $ch = curl_init(); $curl_url = "http://localhost:81/flandy/getpost2.php" . $website . "&pwd=" . $pwd . "&action=check&pseid=" . $psecode . "&amt=" . $amt; curl_setopt($ch, CURLOPT_URL, $curl_url); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//不直接输出，返回到变量 $curl_result = curl_exec($ch); $result = explode(',', $curl_result); curl_close($ch); print_r($result); ?>

getpost2.php的内容如下：

<"returndata<br>"; echo "<pre>"; print_r($_REQUEST); echo "</pre>"; ?>

结果输出：

Array ( [0] => returndata Array ( [web] => 'wwwbaiducom' [pwd] => 123456 [action] => check [pseid] => 'NDE005' [amt] => 1 ) )

方法三：这个要借助第三方类库HttpClient

或者点击此处本站下载。

<?php require_once 'HttpClient.class.php'; $params = array('web' => 'www.baidu.com', 'pwd' => '123456', 'action' => 'check', 'pseid' => 'NDE005', 'amt' => 1); $pageContents = HttpClient::quickPost('http://localhost:81/flandy/getpost3.php', $params); $result = explode(',', $pageContents); print_r($result); ?>

希望本文所述对大家PHP程序设计有所帮助。
