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',
duration: 2000
});
}
});
三、更快速开发
上述代码中的函数请到下面的地址中的DEMO下载
WxappPlugin4SublimeText - sublime_text的微信小程序开发插件，能自动提示和代码补全。非常不错哦
