使用PHP Socket 编程模拟Http post和get请求
这里给大家分享一段使用PHPSocket编程模拟Httppost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：
<?php
$flag=0;
$params='';
$errno='';
$errstr='';
//要post的数据
$argv=array(
'var1'=>'abc',
'var2'=>'howareyou,myfriend??');
//构造要post的字符串
foreach($argvas$key=>$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,$errstr,10)orexit($errstr."--->".$errno);
//构造post请求的头
$header ="POST/flandy/getpost.phpHTTP/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); ?>
