telnet模拟http请求：
cmd进去以后输入：telnet 127.0.0.1 80 回车（如果程序用不了，那么进去控制面板->程序和功能->打开或关闭windows功能，勾选telnet客户端即可），然后按下ctrl+]，回车就可以了
-------------------------
GET请求：
GET http://localhost/test.php HTTP/1.1
HOST:localhost
注意要多一行空格
------------------------
接下来是POST请求：
POST http://localhost/test.php HTTP/1.1
HOST:localhost
Content-type:application/x-www-form-urlencoded
act=query&name=zzz
--------------------------
file_get_contents模拟表单提交(这里是post提交)
<?php ???????$postData = array( ???????‘title‘=> ‘我是file_get_contents的构造数据‘, ???????‘content‘=> ‘我是file_get_contents的构造数据内容‘, ???????‘publish‘=> ‘发布‘, ???); ???$postData = http_build_query($postData); ???$opts = array( ?????‘http‘=>array( ???????‘method‘=>"POST", ???????‘header‘=>"Host:localhost\r\n" . ?????????????????"Content-type:application/x-www-form-urlencoded\r\n" . ?????????????????"Content-length:" . strlen($postData) . "\r\n", ???????‘content‘=>$postData, ?????) ???); ???$context = stream_context_create($opts); ???file_get_contents("http://localhost/http/index.php",false,$context);fopen模拟表单提交
<?php ???????$postData = array( ???????‘title‘=> ‘我是fopen的构造数据‘, ???????‘content‘=> ‘我是fopen的构造数据内容‘, ???????‘publish‘=> ‘发布‘, ???); ???$postData = http_build_query($postData); ???$opts = array( ?????‘http‘=>array( ???????‘method‘=>"POST", ???????‘header‘=>"Host:localhost\r\n" . ?????????????????"Content-type:application/x-www-form-urlencoded\r\n" . ?????????????????"Content-length:" . strlen($postData) . "\r\n", ???????‘content‘=>$postData, ?????) ???); ???$context = stream_context_create($opts); ???$fp = fopen("http://localhost/http/index.php","r",false,$context); ???????$fclose($fp);curl方式模拟表单提交
$url = "http://localhost/http/index.php"; ???$postData = array( ???????‘title‘=> ‘我是curl的构造数据‘, ???????‘content‘=> ‘我是curl的构造数据内容‘, ???????‘publish‘=> ‘发布‘, ???); ???//初始化一个curl会话 ???$ch = curl_init(); ???//设置相应的会话选项 ???curl_setopt($ch, CURLOPT_URL, $url);//设置提交网址 ???curl_setopt($ch, CURLOPT_POST, 1); //设置提交方式，值为1表示肯定 ???curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); //设置提交数据 ???$output = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //提交成功后把数据返回成字符串 ???//执行 ???curl_exec($ch); ???//关闭 ???curl_close($ch); ???echo $output;
