1、在uniapp中配置小程序appid
打开 manifest.json ，找到微信小程序配置，填写 appid 重启应用；
// 您需要注册成为微信小程序开发者才能获取 appid
2、视图添加登录按钮
<template>
<view>
<!-- #ifdef MP-WEIXIN -->
<button type="primary" open-type="getUserInfo" @getuserinfo="getUserInfo">使用微信登录</button>
<!-- #endif -->
</view>
</template>3、js 核心代码
<script>
var _self, pageOptions, session_key, openid;
export default {
data() {
return {
};
},
methods:{
// #ifdef MP-WEIXIN
getUserInfo : (info) => {
