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/1.1/r/n"; $header .= "Host:127.0.0.1/r/n"; $header .= "Referer:/flandy/post.php/r/n"; $header .= "Content-Type: application/x-www-form-urlencoded/r/n"; $header .= "Content-Length: ".$length."/r/n"; $header .= "Connection: Close/r/n/r/n"; //添加post的字符串 $header .= $params."/r/n"; //发送post的数据 fputs($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 == "/r/n")) { $inheader = 0; } if ($inheader == 0) { echo $line; } }fclose($fp);?>getpost.php的内容如下:
<?phpecho "this is the data posted";echo "<pre>";print_r($_REQUEST);echo "</pre>";?>
结果输出：
this is the data postedArray( [var1] => abc [var2] => how are you , my friend??)
以上代码在本机81端口下已经通过测试。
方法二：使用PHP的curl扩展或HttpClient.class.php类，这两个非常类似，下面简单的列出curl的实现代码。
两个文件post2.php和getpost2.php
post2.php的内容如下：
<?php$psecode = 'NDE005';$website = 'www.baidu.com';$amt = 1;$pwd = 123456;$ch = curl_init();$curl_url = "http://localhost:81/flandy/getpost2.php?web=" . $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($result);?>getpost2.php的内容如下：
<?phpecho "returndata<br>";echo "<pre>";print_r($_REQUEST);echo "</pre>";?>
结果输出：
Array ( [0] => returndataArray( [web] => 'wwwbaiducom' [pwd] => 123456 [action] => check [pseid] => 'NDE005' [amt] => 1))
方法三：这个要借助第三方类库HttpClient
可以到这里下载：http://scripts.incutio.com/httpclient/
或者点击此处本站下载。
<?phprequire_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。
