这是带header的

function login()
	{
		$mobile = $this->input->get('mobile',TRUE);
		$mobilecode = $this->input->get('mobilecode',TRUE);
		$uniqueId = $this->input->get('uid',TRUE);
	    $headersLogin = array(
	        "X-Ca-Stage:TEST",  
	        "Authorization:APPCODE 398e4de4d3694c9d93e9b6394b8fad2e",
	        "Content-Type:application/x-www-form-urlencoded; charset=utf-8",
	        "channelId:1",
	        "empid:H5LINE",
	    );  
	    $urlLogin = "https://api.xxx.com/v1/auth/nuskin/user/b2cmember/auth";
	    $dataLogin = array(
	        "userCode"          => $mobile,
	        "verifyCode"        => $mobilecode,
	        "trench"            => "wx",
	        "loginType"         => "mobile",
	        "uniqueId"          => $uniqueId,
	        "loginFlag"         => 2,
	        "loginSource"       => 2,
	    );

	    $resDataLogin = $this->http_request($urlLogin,"POST",$dataLogin,$headersLogin);


	    $notice = array('status'=>200,'msg'=>'操作成功','res'=>json_decode($resDataLogin,TRUE));
	    echo json_encode($notice,JSON_UNESCAPED_UNICODE);
	    exit;
	}

就这么多了，反正是一个值得记录的传header和body以及get，post共同的方法
