1.建立src下建立utils/wx-request.js

const host = 'https://rmall.ukelink.net'
 
function request (url, method, data, header = {}) {
  wx.showLoading({
    title: '載入中' // 資料請求前loading
  })
  return new Promise((resolve, reject) => {
    wx.request({
      url: host + url, // 僅為示例，並非真實的介面地址
      method: method,
      data: data,
      headers: {
        
 
'content-type': 'application/json' // 預設值
      },
      success: function (res) {
        wx.hideLoading()
        resolve(res.data)
      },
      fail: function (res) {
        wx.hideLoading()
        // reject(false)
      },
      complete: function () {
        wx.hideLoading()
      }
    })
  })
}
 
function 
 
get (obj) {
  return request(obj.url, 'GET', obj.data)
}
 
function post (obj) {
  return request(obj.url, 'POST', obj.data)
}
 
export default {
  request,
  get,
  post,
  host
}

2.main.js中引入到原型

import WXrequest from './utils/wx-request'
Vue.prototype.$httpWX = WXrequest

3.使用

this.$httpWX.post({
      url: 
 
'/mms/country/queryValidZoneListForMallHome',
      data: {
        'categoryType': '[email protected]',
        'streamNo': 'web_bss153570682909641893',
        'reqSource': 'MALL_H5',
        'appid': 'string',
        'timestamp': 1535706829096,
        'sign': 'string'
      }
    }).then(res => {
      console.log(res)
    }）
