二、如何使用

在你的JS文头，引用auth.js

  • var auth = require('../../utils/auth.js');
  • // 在调用通讯地址判断是否开启授权，如果没开启就会自动调用授权
  • auth.address({
  • success:function(res){
  • console.log('已授权');
  • // 这儿写你的业务逻辑
  • },
  • fail:function(res){
  • console.log('未授权');
  • wx.showToast({
  • title:'未授权',
  • });
  • }
  • });
