在uniapp官网的uniCloud中下载uni-id用户体系

或者直接进入加载，下载地址：uni-id-pages - DCloud 插件市场 

进入以后下载插件，打开HbuilderX

 选中项目，点击确定

点击跳过

点击合并

右键uniCloud文件夹下的database文件夹，点击“上传所有 DB Schema”

弹出两个弹窗，按下面的图进行勾选和确定

在manifest.json中打开微信小程序配置，配置微信小程序的AppID和勾选上传代码时自动压缩

我们在uniCloud下的uni-id用户体系下的云对象中找到引入云对象的代码，引入到App.vue中

再点击旁边的微信登录，将接口形式中的代码也引入到App.vue中

进行如下配置 

<script setup>
	import {onLaunch, onShow, onHide} from "@dcloudio/uni-app";
	
	// 引入云对象
	const uniIdCo = uniCloud.importObject('uni-id-co')
		
	onLaunch(()=>{
		console.log('App Launch');
		
		uni.login({
			success:login=>{
				uniIdCo.loginByWeixin({
					code:login.code
				}).then(res=>{
					console.log(res);
				})
			}
		})
	})
	
	onShow(()=>{
		console.log('App Show');
	})
	
	onHide(()=>{
		console.log('App Hide');
	})
</script>

<style lang="scss">
	@import "common/style/common_style.scss";
	@import "@/static/fonts/iconfont.css";
</style>

在uniCloud/cloudfunctions/common/uni-config-center中创建uni-id文件夹，再在下面创建config.json文件

在新建的config.json中粘贴如下代码

如果是在官网上进行的代码粘贴，就会有注释，会报下面这个错误，这时候需要删除注释 

 

Ctrl+F，点击 .* ，在里面输入 //.* ，点击替换区，然后点击全部替换，所有的注释都会被替换成空
