( ⊙ o ⊙ )啊！，

That's impossible!!!

Nothing is impossible!!!

理论上工具HttpManager.js是不可引用 const app = getApp()的，也就是里面不能引用其属性globalData
但可以通过在外部页面，或者app.js里面调用HttpManager.setSomeData(theData)来实现 gloabalData往HttpManager.js传值。

示例：

//app.js

const httpManager = require('utils/HttpManager.js')

App({
  onLaunch: function () {
    wx.login({
      success: res => {
        // 发送 res.code 到后台换取 openId, sessionKey, unionId
        httpManager.loginRq({
          api: 'login',
          data: {code: res.code},
          success: function(e) {
            let token = e.data.data.token;
            httpManager.setGlobalToken(token)    //将app内的值传递给HttpManager.js
          },
        })
      }
    })
})

//HttpManager.js

const baseUrl = 'http://mydomain/miniprogram/'

var manager = {

  setGlobalToken: function(token) {
    console.log('tokenSet:' + token)
    this.globalToken = token;
  },

  request: function ({ api, data, method, success, fail, complete }) {
    let token = this.globalToken;
    if (token == '' ) {
      return;
    }
    wx.request({
      url: baseUrl + api,
      data: data,
      method: method,
      success: success,
      fail: fail,
      complete: complete,

      header: {
        "content-type": "application/x-www-form-urlencoded",
        "x-token": token
      }
    })
  },
..
}

module.exports = {
  setGlobalToken: manager.setGlobalToken,
  request: manager.request,
  loginRq: manager.loginRq
}

或者，用缓存的方式传值。山不过来，我就过去~
