how to change promise resolve value in the response

[LiDengHui]

I need change promise resove value

Vue.http.interceptors.push(function (request, next) {
  // ...
  // 请求发送前的处理逻辑
  // ...
  next(function (response) {
    // ...
    // 请求发送后的处理逻辑
    // ...
    // 根据请求的状态，response参数会返回给successCallback或errorCallback
    let res = response.body
    if (typeof res === 'object' && res.code) {
      if (res.code === 200) {
        return response
      } else if (res.code === 4101) {
        // response.ok = false
      } else if (res.code === 5001) {
        // response.ok = false
      } else {
        // response.ok = false
      }
      return request.respondWith(response.body, {
        status: res.code,
        statusText: res.message || '服务器错误'
      })()

response.body.code ===4101 need reject some value.
