    public function DoLogin(){
    	//获取前台数据
          $data=Request::param();
          $username = $data['username'];
          $password = $data['password'];
          $res=UserModel::where('username',$username)->find();
          if (!$res) {
          	$info= ['res'=>0,'msg'=>'用户名不存在！'];
          }elseif ($password!=$res['password']) {
          	$info= ['res'=>0,'msg'=>'密码再想想！'];

          	$info= ['res'=>1,'msg'=>'登录成功！'];
            Session::set('username',$res['username']);
          }
