uniCloud-云对象基本用法

在项目的uniCloud---cloudfunctions文件夹上右键,新建云函数/云对象
单选框选择"云对象", 命名,创建

云对象代码

const db = uniCloud.database()

module.exports = {
	_before: function() {},
	// 定义云对象异步函数
	async get(num) {
		return await db.collection("users").orderBy("_id","desc").limit(num).get()
	},
	// 函数普通写法箭头写法都行
	add:async (dataObj)=>{
		await   db.collection("users").add(dataObj)
	}
}

前端页面代码

<template>
	<view class="content">
		<view v-for="item in dataList" :key="item._id">
			{{item.name}}---{{item.gender}}---{{item.age}}
		</view>
	</view>
</template>

<script>
	// 引入云对象
	const cloudObj1 = uniCloud.importObject("test_cloudObj1")

	export default {
		data() {
			return {
				title: 'Hello',
				dataList: [],
				dataNum: 5
			}
		},
		onLoad() {
			this.getData();
		},
		methods: {
			getData() {
				cloudObj1.add({
					name: "zhang3",
					gender: "男",
					age: 17
				})
				// 云对象获取数据
				cloudObj1.get(this.dataNum).then(res => {
					console.log(res);
					this.dataList = res.data
				}, err => {
					console.log(err.message);
				})

				return;

				// 云函数获取数据
				uniCloud.callFunction({
					name: "test_cloudFun1",
					data: {
						num: this.dataNum
					},
					success: (res) => {
						console.log("success@@@@", res);
						this.dataList = res.result.data;
					},
					fail: (err) => {
						console.log("fail@@@@", err.message);
					}
				})
			}
		}
	}
