const BASE_URL = ‘‘
let ajaxTime = 0
export const myRequest = (option) => {
    ajaxTime++
    uni.showLoading({
        title: "加载中",
        mask: true
    })
    return new Promise((resolve, reject) => {
        uni.request({
            url: BASE_URL + option.url,
            method: option.mehtod || ‘GET‘,
            data: option.data || {},
            success: (res) => {
                if (res.statusCode !== 200) {
                      return uni.showToast({
                        title: "获取失败"
          })
        }
        resolve(res)
      },
      fail: (err) => {
        uni.showToast({
          title: ‘请求接口失败‘
        })
        reject(err)
      },
      complete: () => {
        ajaxTime--
        if (ajaxTime == 0) {
          uni.hideLoading()
//防止同一页面请求多个数据时加载框异常
        }
      }
    })
  })
}

然后在main.js中将封装好的工具组件全局引用

import {myRequest}from ‘utils/request/api.js‘
Vue.prototype.$myRequest=myRequest

小程序接口请求封装
