二、如何使用
在你的JS文頭，引用auth.js
var auth = require('../../utils/auth.js');
// 在調用通訊地址判斷是否開啟授權，如果沒開啟就會自動調用授權
auth.address({
success: function(res) {
console.log('已授權');
// 這兒寫你的業務邏輯
},
fail: function(res) {
console.log('未授權');
wx.showToast({
title: '未授權',
duration: 2000
});
}
});
三、更快速開發
上述代碼中的函數請到下面的地址中的DEMO下載
WxappPlugin4SublimeText - sublime_text的微信小程序開發插件，能自動提示和代碼補全。非常不錯哦
