微信小程序：封装全局的promise异步调用方法

一：封装

function POST(url, params) {
  let promise = new Promise(function (resolve, reject) {
    wx.request({
      url: url,
      data: params,
      method: 'POST',
      success: function (res) {
        resolve(res.data);
      }
    })
  });
  return promise
}

二：调用

const network = require('../../utils/util.js')
 network.GET(url, params).then((res) => {
      //请求成功的操作
      console.log(res)

    });
