# 小程序request接口的封装(本质上是对request回调函数再次回调)module.exports.getData = function (url) {    var data = arguments.length > 1 && arguments[1] !== undefined ? arguments[1] : {};    var method = arguments.length > 2 && arguments[2] !== undefined ? arguments[2] : 'POST';    var header = arguments.length > 3 && arguments[3] !== undefined ? arguments[3] : { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' };    return new Promise(function (resolve, reject) {        wx.request({            url: url,            data: data,            method: method,            header: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' },            success: function (res) {                resolve(res)            },            fail: function (res) {                reject(res)            }        })    })}#---------------------------------------------------#调用方法var common = require("../../common/common.js")common.getData(postUrl)        .then(function(data){          this.setData({          //....          });          console.log(data);        });
