http.class.php

1.声明个接口

interface Proto
{
    // 连接url
    function conn($url);
    // get查询
    function get();
    // post查询
    function post();
    // 关闭连接
    function close();
}

2.实现类

构造请求行、请求头信息、请求主体信息

class Http implements Proto
{
    //请求行、请求头信息、请求主体信息
    protected $url = null;
    protected $fh = null;
    protected $line = array();
    protected $version = 'HTTP/1.1'; 
    protected $header = array();
    protected $body = array();
    protected $response = '';
    protected $errno = -1;
    protected $errstr = '';

    public function __construct($url)
    {
        $this->conn($url);
        $this->setHeader('Host: ' . $this->url['host']);
    }
    // 请求行
    protected function setLine($method)
    {
        $this->line[0] = $method. ' ' . $this->url['path'] . '?' . $this->url['query'] . ' ' . $this->version;
    }

    // 请求头信息
    public function setHeader($headerline)
    {
        $this->header[] = $headerline;
    }

    // 请求主体信息
    protected function setBody($body)
    {
        // $this->body = array_merge($this->body,$body);
        $this->body[] = http_build_query($body);
    }

    function conn($url)
    {
        $this->url = parse_url($url);
        // 判断端口
        if(!isset($this->url['port']))
            $this->url['port'] = 80;
        $this->fh = fsockopen($this->url['host'],$this->url['port'],$this->errno,$this->errstr,3);
    }
    
    public function get()
    {
        $this->setLine('GET');
        $this->request();
        return $this->response;
    }

    public function post($body = array())
    {
        $this->setLine('POST');

        //content-type&&content-length
        $this->setHeader('Content-type: application/x-www-form-urlencoded');
        // 设计主体信息,跟GET不一样的地方
        $this->setBody($body);

        $this->setHeader('Content-length: ' . strlen($this->body[0]));
        $this->request();
        return $this->response;
    }

    // request里面合并请求数组
    public function request()
    {
        $req = array_merge($this->line, $this->header, array(''), $this->body,array(''));
        $req =  implode(PHP_EOL, $req);
        // echo $req;die;
        fwrite($this->fh, $req);
        while(!feof($this->fh))
        {
            $this->response .= fread($this->fh,1024);
        }
        $this->close();
        // return $this->response;
        // var_dump($this->response);
    }

    function close()
    {
        fclose($this->fh);
    }

    
}

// $url = 'http://news.163.com/15/1219/10/BB6K60P000014PRF.html';
// $http = new Http($url);
// echo $http->get();
// $str = str_shuffle('abcddedghijklmnopqrstuvwxyz0123456789');
// $message = substr($str, 0,10);
// $posttime = time();
// $msg = array('message'=>$message, 'posttime'=>$posttime, 'formhash'=>'b49016a2');
// $url = 'http://home.verycd.com/cp.php?ac=pm';
// $http = new Http($url);

// echo $http->post($msg);

?>

3.POST实例
