第四节 curl和socket方式提交表单

一.curl

$url = 'http://localhost/http/1.php';$postData = array(        'title'=>'我是curl',        'content'=>'我是curl的内容'    );//1.初始化一个curl会话$ch = curl_init();//2.设置相应的会话选项//设置提交的网址curl_setopt($ch,CURLOPT_URL,$url);//设置数据提交的方式curl_setopt($ch,CURLOPT_POST,1);curl_setopt($ch,CURLOPT_POSTFIELDS,$postData);//提交成功之后,把数据返回为字符串curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);//3.提交会话$str=curl_exec($ch);//4.关闭会话curl_close($ch);echo $str;

二.socket

fsockopen(主机,端口,错误号,错误信息,套接字);

fsockopen( string $hostname [, int $port = -1 [, int &$errno [, string &$errstr [, float $timeout = ini_get("default_socket_timeout") ]]]] )

$postData = array(        'title'=>'我是socket方式提交的',        'content'=>'我是socket的内容'    );$postData = http_build_query($postData);$fp = fsockopen('localhost',80,$errno,$errorStr,5);$request = "POST http://localhost/http/1.php HTTP/1.1"."\r\n";$request .="Host:localhost\r\n";$request .="Content-type:application/x-www-form-urlencoded\r\n";$request .="Content-length:".strlen($postData)."\r\n\r\n";$request .= $postData;//var_dump($request);fwrite($fp,$request);//读取数据while(!feof($fp)){    echo fgets($fp,1024);}
