before(app){
      app.get('/api/getDiscList', function (req, res) {
        var url = 'https://c.y.qq.com/splcloud/fcgi-bin/fcg_get_diss_by_tag.fcg' 
        axios.get(url, {
          headers: {
          referer: 'https://c.y.qq.com/',
          host: 'c.y.qq.com' 
      },
          params: req.query
        }).then((response) => {
          res.json(response.data)
        }).catch((e) => {
          console.log(e)
        })
      })
    }

配置代理不知道为啥写before后出问题。
