因为也是学习的路上，先画出思路，代码和看别人的学习的，最后是根据的思路完成的，可能比较简单，后期在去完善和更改

     conn($url);		$this->setHeader('Host: ' . $this->url['host']);	}	// 请求行	protected function setLine($method){		$this->line[0] = $method . ' ' . $this->url['path'] .  ' ' . 'HTTP/1.1';	}	// 头信息	public function setHeader($headerline){		$this->header[] = $headerline;	}	// 主体信息	protected function setBody($body){                $this->body[] = http_build_query($body);	}	// 连接url	public function conn($url){		$this->url = parse_url($url);		if(!isset($this->url['port'])){			$this->url['port'] = 80;		}		$this->fh = fsockopen($this->url['host'],$this->url['port'],$this->errno,$this->errorstr,3);	}	// 构建get请求	public function get(){		$this->setLine('GET');		$this->request();		return $this->response;	}	// 发送post请求	public function post($bo){		$this->setLine('POST');                // content-type                $this->setHeader("Content-type: application/x-www-form-urlencoded");                $this->setBody($bo);                // content-length                $this->setHeader("Content-length: " .strlen($this->body[0]));                $this->request();                return $this->response;	}	public function request(){		$req = array_merge($this->line,$this->header,array(''),$this->body,array(''));		//print_r($req);die;		$req = implode(PHP_EOL,$req); // PHP_EOL 换行//		echo $req;die;		fwrite($this->fh,$req);		while(!feof($this->fh)){			$this->response .= fread($this->fh,1024);		}		$this->close();	}	public function close(){            fclose($this->fh);	}}

 上面是简单的类

     setHeader("Cookie:xxxx");$http->setHeader("Referer: http://www.cnblogs.com/geek12/p/4024793.html");$http->setHeader("User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0");$msg =array("blogApp"=>"geek12","body"=>"来自robot","parentCommentId"=>0,"postId"=>4024793);$http->post($msg);

 发送成功的截图

在写的过程中遇到的几个问题，根据请求的url 不一样，请求头的拼接也需要改变，这里请求的url是 http://www.cnblogs.com/mvc/PostComment/Add.aspx  静态的连接，所有path 直接拿到后面的，如果是动态的就需要修改了，所以本方法只适合静态的连接，动态的需要修改请求头

不是所有的网站都可以模拟，虽然没有验证码，我在VeryCd 网站，怎么模拟都没有成功，最后只好放弃了

我是菜鸟，请不要抨击，待续。。。。
