微信小程序 request接口的封裝實例代碼

小程序request接口的封裝(本質上是對request回調函數再次回調)

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)  } }) })}

調用方法

var common = require("../../common/common.js")common.getData(postUrl) .then(function(data){  this.setData({  //....  });  console.log(data); });
