使用PHP Socket 编程模拟Http post和get请求_php实例

这里给大家分享一段使用PHP Socket 编程模拟Http post和get请求的代码，非常的实用，结尾部分我们再讨论下php模拟http请求的几种方法。

php 模拟 http请求

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：

<br /><?php<br /> $flag = 0;<br /> $params = '';<br /> $errno = '';<br /> $errstr = '';<br /> //要post的数据<br />$argv = array(<br />    'var1'=>'abc',<br />    'var2'=>'how are you , my friend??');<br />//构造要post的字符串<br />foreach ($argv as $key=>$value) {<br />    if ($flag!=0) {<br />        $params .= <div>本文#来源gaodai.ma#com搞##代!^码7网</div><pre>搞代gaodaima码

“&”;
$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

<br /><?php<br />echo "this is the data posted";<br />echo "<pre class="prettyprint linenums">";<br />print_r($_REQUEST);<br />echo "

“;
?>

结果输出：

<br />this is the data postedArray<br />(<br />[var1] => abc<br />[var2] => how are you , my friend??<br />)<br />

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：

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

getpost2.php的内容如下：

<br /><?php<br />echo "returndata<br>";<br />echo "<pre class="prettyprint linenums">";<br />print_r($_REQUEST);<br />echo "

“;
?>

结果输出：

<br />Array ( [0] => returndataArray<br />(<br />[web] => 'wwwbaiducom'<br />[pwd] => 123456<br />[action] => check<br />[pseid] => 'NDE005'<br />[amt] => 1<br />)<br />) <br />

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/

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