我在前端的请求是这样的：

//获取强档推荐数据
        $.ajax({
          url: '/ly/Recommend/get/',
          data: {
            adpos: 907,
            num: 24,
            pool_id: 302
          },
          success(data){
            let obj = JSON.parse(data);

            console.log(obj);
          },
          error(error){
            console.log(error);
          }
        });

我在服务端用 http-proxy-middleware 做了代理：

let o = {
    target: 'https://ac.qq.com/', 
    changeOrigin: true,
    pathRewrite: {
        '^/ly': ''
    }
};

app.use('/ly', proxy(o));

用谷歌浏览器测试，pc 端请求成功，而移动端模式报错：
Failed to load https://m.ac.qq.com/Recommend/get/: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8088' is therefore not allowed access.
可以看到，请求地址代理到了 https://m.ac.qq.com/，但是我明明写的是 https://ac.qq.com/ ，请问这个问题该怎么解决？
