var app = getApp()

----------------------------------------------
 data: {     //相当于 display
bindViewTap: function() {   //相当于类方法
onLoad: function () {          //相当于构造函数
bindtap="bindViewTap"     //相当于页面上调用方法的a链接    action="{:U(‘news/add‘)}" 
     bindViewTap: function() {
wx.navigateTo({                //指定链接跳转地址

发送请求
wx.request({
  url: ‘test.php‘, //仅为示例，并非真实的接口地址
  data: {
     x: ‘‘ ,
     y: ‘‘
  },
  header: {
      ‘content-type‘: ‘application/json‘
  },
  success: function(res) {
    console.log(res.data)
