本人小白一枚，看文檔是 GatewayWorker發(fā)現(xiàn)有頁(yè)面發(fā)起連接時(shí)，將對(duì)應(yīng)連接的client_id發(fā)給網(wǎng)站頁(yè)面這一步驟的時(shí)候，發(fā)起ajax請(qǐng)求之后出現(xiàn)跨域問(wèn)題，
前端頁(yè)面請(qǐng)求：

$.ajax({
  type: 'post',
  url: 'http://www.tp5.com/bind/index',
  data: {
        client_id:data['client_id']
  },
  dataType: 'json',
  success: function(data) {
        alert(data.state);
  }
})

bind.php:

<?php

namespace app\controller;

//加載GatewayClient。關(guān)于GatewayClient參見(jiàn)本頁(yè)面底部介紹
require_once 'E:\phpstudy\phpstudy_pro\WWW\fgw\public\static\GatewayClient-master\Gateway.php';
// GatewayClient 3.0.0版本開(kāi)始要使用命名空間
use GatewayClient\Gateway;

// 設(shè)置GatewayWorker服務(wù)的Register服務(wù)ip和端口，請(qǐng)根據(jù)實(shí)際情況改成實(shí)際值(ip不能是0.0.0.0)

class Bind extends Base

    public function index(Request $request)
    {   header("Access-Control-Allow-Origin: *");
        $client_id=$request->post('client_id');
        Gateway::$registerAddress = '127.0.0.1:1236';
        // 假設(shè)用戶(hù)已經(jīng)登錄，用戶(hù)uid和群組id在session中
        $uid= 1;
        $group_id = 1;
        // client_id與uid綁定
        Gateway::bindUid($client_id, $uid);
        // 加入某個(gè)群組（可調(diào)用多次加入多個(gè)群組）
        Gateway::joinGroup($client_id, $group_id);
        echo json_encode(array('state'=>'success'));
    }
}
