由于微信官方修改了 getUserInfo 接口,所以现在无法实现一进入微信小程序就弹出授权窗口,只能通过 button 去触发。官方连接:https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html
微信小程序登录流程时序
说明:
自己写一个微信授权登录页面让用户实现点击的功能,也就是实现了通过 button 组件去触发 getUserInfo接口。在用户进入微信小程序的时候,判断用户是否授权了,如果没有授权的话就显示授权页面,让用户去执行授权的操作。如果已经授权了,则直接跳过这个页面,进入首页。
获取手机号也类似:调用getPhoneNumber方法
1, index.wxml
绑定手机号
请先绑定手机号在进行此操作
2, index.js

注解:
1,点击登录按钮,弹出微信自带的是否允许授权弹出框,
2,如果点击的是允许,从缓存中读取用户信息,并把用户信息存储起来,
3,同时调用弹出获取手机号的弹窗(这个弹窗时自己写的),在wxml里用wx:if="{{showModal}}"判断获取手机号的隐藏状态,当为true的时候显示,
4,注意在两层view里写了两遍wx:if="{{showModal}}",为什么写两遍呢,因为第一层时弹出框的灰色蒙版背景,第二层是弹出框的内容,两层控制了整个弹窗框是否显示。
