cloudbase-vue-next v0.1.3

云开发 Vue3插件

云开发 Vue 插件 是云开发官方维护的 Vue 插件，提供全局入口、Vue 逻辑组件等功能。

安装

npm install --save cloudbase-vue-next

使用

下面我们使用 LoginState 组件，来动态绑定当前页面的登录态。

• 页面初始化时，显示 '未登录'
• 之后我们调用匿名登录(https://docs.cloudbase.net/authentication/ anonymous.html)，如果登录成功，则文案将变成 '已登录'

main.js

import {createApp} from "vue"
import Cloudbase from "cloudbase-vue-next"
import App from "./App.vue"
const app = createApp(App)
app.use(Cloudbase, {
    env: "your-env-id",
    region: "your-env-region"
})
app.mount('#app');

App.vue

<template>
  <div id="app">
    <h1>Hello world</h1>
    <LoginState v-slot="{ loginState }">
      <h1>{{ loginState ? "已登录" : "未登录" }}</h1>
    </LoginState>
    <button @click="callFn">调用云函数</button>
  </div>
</template>

<script>
export default {
  async created() {
    // 以匿名登录为例
    await this.$cloudbase
      .auth({ persistence: "local" })
      .anonymousAuthProvider()
      .signIn();
  },
  methods: {
    callFn() {
      this.$cloudbase
        .callFunction({
          name: "vue-echo",
          data: { meg: "Hello world" },
        })
        .then((res) => {
          const result = res.result; //云函数执行结果
          console.log(result);
        });
    },
  },
};
</script>

在setup中使用

<template>
  <div id="app">
    <h1>Hello world</h1>
    <LoginState v-slot="{ loginState }">
      <h1>{{ loginState ? "已登录" : "未登录" }}</h1>
    </LoginState>
    <button @click="callFn">调用云函数</button>
  </div>
</template>

<script>
import { useCloud } from "cloudbase-vue-next"
export default {
  setup(){
    const cloudbase = useCloud({
      env: "your-env-id",
      region: "your-env-region"
    });
    //登录授权
    cloudbase
      .auth({ persistence: "local" })
      .anonymousAuthProvider()
      .signIn();
    //请求函数
    const callFn=()=>{
      cloudbase
      .callFunction({
        name: "vue-echo",
        data: { meg: "Hello world" },
      })
      .then((res) => {
        const result = res.result; //云函数执行结果
        console.log(result);
      });
    }

    return {
      callFn
    }
  }
};
</script>

Plugin API

Vue.$cloudbase

可以在 Vue 组件的 this.$cloudbase 中，获取 Cloudbase 实例

export default {
  data() {
    return {
      docs: []
    }
  },
  async created() {
    // 登录
    await this.$cloudbase.auth({ persistence: "local" }).signInWithTicket(ticket)
    // 数据库查询
    const queryResult = await this.$cloudbase.database().collection('test').where({}).get()
    this.docs = queryResult.data
  }
}
