MemFire Cloud是一款提供云数据库,用户可以创建云数据库,并对数据库进行管理,还可以对数据库进行备份操作。它还提供后端即服务,用户可以在1分钟内新建一个应用,使用自动生成的API和SDK,访问云数据库、对象存储、用户认证与授权等功能,可专注于编写前端应用程序代码,加速WEB或APP应用开发。
此示例提供了使用 MemFire Cloud 和 Vue3 构建简单用户管理应用程序(从头开始)的步骤。这包括:
-
MemFire Cloud云数据库:用于存储用户数据的 MemFireDB数据库。
-
MemFire Cloud用户验证:用户可以使用魔法链接登录(只需要电子邮件,不需要密码)。
-
MemFire Cloud存储:用户可以上传照片。
-
行级安全策略:数据受到保护,因此个人只能访问自己的数据。
-
即时API:创建数据库表时会自动生成 API。
在本指南结束时,您将拥有一个允许用户登录和更新一些基本个人资料详细信息的应用程序:

创建应用
目的:我们的应用就是通过在这里创建的应用来获得数据库、云存储等一系列资源,并将获得该应用专属的API访问链接和访问密钥,用户可以轻松的与以上资源进行交互。

-- Create a table for public "profiles" create table profiles ( id uuid references auth.users not null, updated_at timestamp with time zone, username text unique, avatar_url text, website text, primary key (id), unique(username), ); alter table profiles enable row level security; create policy "Public profiles are viewable by everyone." on profiles for select using ( true ); create policy "Users can insert their own profile." on profiles for insert with check ( auth.uid() = id ); create policy "Users can update own profile." on profiles for update using ( auth.uid() = id ); -- Set up Storage! insert into storage.buckets (id, name) values ('avatars', 'avatars'); create policy "Avatar images are publicly accessible." on storage.objects for select using ( bucket_id = 'avatars' ); create policy "Anyone can upload an avatar." on storage.objects for insert with check ( bucket_id = 'avatars' );
获取 API密钥
现在您已经创建了一些数据库表,您可以使用自动生成的 API 插入数据。我们只需要从API设置中获取您在上面复制的URL和anon的密钥。
在应用->概括页面,获取服务地址以及token信息。

Anon(公开)密钥是客户端API密钥。它允许“匿名访问”您的数据库,直到用户登录。登录后,密钥将切换到用户自己的登录令牌。这将为数据启用行级安全性。
注意:service_role(秘密)密钥可以绕过任何安全策略完全访问您的数据。这些密钥必须保密,并且要在服务器环境中使用,绝不能在客户端或浏览器上使用。 在后续示例代码中,需要提供supabaseUrl和supabaseKey。
认证设置
当用户点击邮件内魔法链接进行登录时,是需要跳转到我们应用的登录界面的。这里需要在认证设置中进行相关URL重定向的配置。
因为我们最终的应用会在本地的3000端口启动(亦或者其他端口),所以这里我们暂时将url设置为http://localhost:3000/
除此之外,在此界面也可以自定义使用我们自己的smtp服务器。

构建应用程序
让我们从头开始构建 Vue3应用程序。
初始化一个 Vue3应用程序
需要 Node.js (>=14.15 <=16.10) 。
我们可以快速使用Vite 和 Vue 3 模板来初始化一个名为memfiredb-vue-3:
npm init vite memfiredb-vue-3 --template vue cd memfiredb-vue-3
然后让我们安装唯一的附加依赖项:supabase-js
npm install @supabase/supabase-js
接下来我们需要创建一个可以访问我们应用程序数据的客户端,我们使用了Supabase 客户端,使用他生态里提供的功能(登录、注册、增删改查等)去进行交互。创建一个可以访问我们应用程序数据的客户端需要接口的地址(URL)和一个数据权限的令牌(ANON_KEY),我们需要去应用的概览里面去获取这两个参数然后配置到supabaseClient.js里面去。
src/supabaseClient.js
import { createClient } from '@supabase/supabase-js' const url = URL const key = ANON_KEY export const supabase = createClient(url,key)
更新样式
可以看到界面实在是不怎么优雅,更新下样式,让它好看一些。 修改src/style.css文件。

设置登录组件
让我们新建一个组件来管理登录和注册。我们将使用 Magic Links,因此用户无需使用密码即可使用电子邮件登录。
/src/components/Auth.vue
<template> <form class="row flex flex-center" @submit.prevent="handleLogin"> <div class="col-6 form-widget"> <h1 class="header">MemFire Cloud + Vue 3</h1> <p class="description">使用下面的电子邮件通过魔法链接登录</p> <div> <input class="inputField" type="email" placeholder="邮箱" v-model="email" /> </div> <div> <input type="submit" class="button block" :value="loading ? 'Loading' : '发送魔法链接'" :disabled="loading" /> </div> </div> </form> </template> <script> import { ref } from "vue"; import { supabase } from "../supabaseClient"; export default { setup() { const loading = ref(false); const email = ref(""); const handleLogin = async () => { try { loading.value = true; const { error } = await supabase.auth.signIn({ email: email.value }); if (error) throw error; alert("请检查您的电子邮件以获取登录链接!"); } catch (error) { alert(error.error_description || error.message); } finally { loading.value = false; } }; return { loading, email, handleLogin, }; }, }; </script>
获取用户个人信息
为了访问其他地方的用户信息,我们使用了响应式存储。创建一个名为store.js并利用 Vue 3reactive功能的新文件。
src/store.js
import { reactive } from "vue" export const store = reactive({ user: {}, })
用户信息页面
用户登录后,我们可以允许他们编辑他们的个人资料详细信息并管理他们的帐户。让我们为它创建一个名为Profile.vue的组件.
src/components/Profile.vue
<template> <form class="form-widget" @submit.prevent="updateProfile"> <div> <label for="email">Email</label> <input id="email" type="text" :value="store.user.email" disabled /> </div> <div> <label for="username">名称</label> <input id="username" type="text" v-model="username" /> </div> <div> <label for="website">网址</label> <input id="website" type="website" v-model="website" /> </div> <div> <input type="submit" class="button block primary" :value="loading ? 'Loading ...' : '修改'" :disabled="loading" /> </div> <div> <button class="button block" @click="signOut" :disabled="loading"> 登出 </button> </div> </form> </template> <script> import { supabase } from "../supabaseClient" import { store } from "../store" import { onMounted, ref } from "vue" export default { setup() { const loading = ref(true) const username = ref("") const website = ref("") const avatar_url = ref("") async function getProfile() { try { loading.value = true store.user = supabase.auth.user() let { data, error, status } = await supabase .from("profiles") .select(`username, website, avatar_url`) .eq("id", store.user.id) .single() if (error && status !== 406) throw error if (data) { username.value = data.username website.value = data.website avatar_url.value = data.avatar_url } } catch (error) { alert(error.message) } finally { loading.value = false } } async function updateProfile() { try { loading.value = true store.user = supabase.auth.user() const updates = { id: store.user.id, username: username.value, website: website.value, avatar_url: avatar_url.value, updated_at: new Date(), } let { error } = await supabase.from("profiles").upsert(updates, { returning: "minimal", // Don't return the value after inserting }) alert('修改成功!') if (error) throw error } catch (error) { alert(error.message) } finally { loading.value = false } } async function signOut() { try { loading.value = true let { error } = await supabase.auth.signOut() if (error) throw error } catch (error) { alert(error.message) } finally { loading.value = false } } onMounted(() => { getProfile() }) return { store, loading, username, website, avatar_url, updateProfile, signOut, } }, } </script>
修改项目入口文件
现在我们已经准备好所有组件,让我们更新App.vue:
src/App.vue
<template> <div class="container" style="padding: 50px 0 100px 0"> <Profile v-if="store.user" /> <Auth v-else /> </div> </template> <script> import { store } from "./store" import { supabase } from "./supabaseClient" import Auth from "./components/Auth.vue" import Profile from "./components/Profile.vue" export default { components: { Auth, Profile, }, setup() { store.user = supabase.auth.user() supabase.auth.onAuthStateChange((_, session) => { store.user = session.user }) return { store, } }, } </script>
你可以通过 --port 参数来配置服务的运行端口。
package.json
{ "scripts": { "preview": "vite preview --port 3000" } }
完成后,在终端窗口中运行它:
npm run build npm run preview
然后打开终端提示的端口链接,你应该会看到完整的应用程序。

实现:上传头像及更新用户信息
每个 MemFire Cloud 项目都配置了存储,用于管理照片和视频等大文件。
创建上传小组件
让我们为用户创建一个头像,以便他们可以上传个人资料照片。我们可以从创建一个新组件开始:
src/Avatar.vue
<template> <div> <img v-if="src" :src="src" alt="Avatar" class="avatar image" :style="{ height: size, width: size }" /> <div v-else class="avatar no-image" :style="{ height: size, width: size }" /> <div :style="{ width: size }"> <label class="button primary block" for="single"> {{ uploading ? "Uploading ..." : "Upload" }} </label> <input style="visibility: hidden; position: absolute" type="file" id="single" accept="image/*" @change="uploadAvatar" :disabled="uploading" /> </div> </div> </template> <script> import { ref, toRefs, watch } from "vue" import { supabase } from "./supabaseClient" export default { props: { path: String, }, emits: ["upload", "update:path"], setup(prop, { emit }) { const { path } = toRefs(prop) const size = ref("10em") const uploading = ref(false) const src = ref("") const files = ref() const downloadImage = async () => { try { const { data, error } = await supabase.storage .from("avatars") .download(path.value) if (error) throw error src.value = URL.createObjectURL(data) } catch (error) { console.error("Error downloading image: ", error.message) } } const uploadAvatar = async (evt) => { files.value = evt.target.files try { uploading.value = true if (!files.value || files.value.length === 0) { throw new Error("请选择一个图片上传") } const file = files.value[0] const fileExt = file.name.split(".").pop() const fileName = `${Math.random()}.${fileExt}` const filePath = `${fileName}` let { error: uploadError } = await supabase.storage .from("avatars") .upload(filePath, file) if (uploadError) throw uploadError emit("update:path", filePath) emit("upload") } catch (error) { alert(error.message) } finally { uploading.value = false } } watch(path, () => { if (path.value) downloadImage() }) return { size, uploading, src, files, uploadAvatar, } }, } </script>
将组建引入到Profile.vue页面
src/components/Profile.vue
<template> <form class="form-widget" @submit.prevent="updateProfile"> <div> <label for="email">Email</label> <input id="email" type="text" :value="store.user.email" disabled /> </div> <div> <label for="username">名称</label> <input id="username" type="text" v-model="username" /> </div> <div> <label for="website">网址</label> <input id="website" type="website" v-model="website" /> </div> <Avatar v-model:path="avatar_url" @upload="updateProfile" /> <div> <input type="submit" class="button block primary" :value="loading ? 'Loading ...' : '修改'" :disabled="loading" /> </div> <div> <button class="button block" @click="signOut" :disabled="loading"> 登出 </button> </div> </form> </template> <script> import { supabase } from "../supabaseClient" import { store } from "../store" import { onMounted, ref } from "vue" import Avatar from './Avatar.vue' export default { components: { Avatar, }, setup() { const loading = ref(true) const username = ref("") const website = ref("") const avatar_url = ref("") async function getProfile() { try { loading.value = true store.user = supabase.auth.user() let { data, error, status } = await supabase .from("profiles") .select(`username, website, avatar_url`) .eq("id", store.user.id) .single() if (error && status !== 406) throw error if (data) { username.value = data.username website.value = data.website avatar_url.value = data.avatar_url } } catch (error) { alert(error.message) } finally { loading.value = false } } async function updateProfile() { try { loading.value = true store.user = supabase.auth.user() const updates = { id: store.user.id, username: username.value, website: website.value, avatar_url: avatar_url.value, updated_at: new Date(), } let { error } = await supabase.from("profiles").upsert(updates, { returning: "minimal", // Don't return the value after inserting }) alert('修改成功!') if (error) throw error } catch (error) { alert(error.message) } finally { loading.value = false } } async function signOut() { try { loading.value = true let { error } = await supabase.auth.signOut() if (error) throw error } catch (error) { alert(error.message) } finally { loading.value = false } } onMounted(() => { getProfile() }) return { store, loading, username, website, avatar_url, updateProfile, signOut, } }, } </script>
恭喜!在这个阶段,您拥有一个功能齐全的应用程序!
