|
|
|
|
NocoBase 采用微内核架构,框架只保留核心,各类功能以插件形式扩展。

## 微服务 - Microservices
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
为了更快的理解 NocoBase,我们先创建一个应用,新建一个 app.js 文件,代码如下:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-14 03:09:26 +00:00
|
|
|
|
const { Application } = require('@nocobase/server');
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
const app = new Application({
|
|
|
|
|
// 省略配置信息
|
|
|
|
|
});
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
// 配置一张 users 表
|
2021-09-14 03:09:26 +00:00
|
|
|
|
app.collection({
|
2021-09-11 10:54:03 +00:00
|
|
|
|
name: 'users',
|
2021-09-16 07:57:21 +00:00
|
|
|
|
schema: [
|
|
|
|
|
{ type: 'string', name: 'username' },
|
|
|
|
|
{ type: 'password', name: 'password' }
|
|
|
|
|
],
|
2021-09-11 10:54:03 +00:00
|
|
|
|
});
|
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
// 解析 argv 参数,终端通过命令行进行不同操作
|
|
|
|
|
app.parse(process.argv);
|
2021-09-11 10:54:03 +00:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
终端运行
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# 根据配置生成数据库表结构
|
2021-09-16 07:57:21 +00:00
|
|
|
|
node app.js db:sync
|
2021-09-11 10:54:03 +00:00
|
|
|
|
# 启动应用
|
2021-09-14 03:09:26 +00:00
|
|
|
|
node app.js start --port=3000
|
2021-09-11 10:54:03 +00:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
相关 users 表的 REST API 就生成了
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
GET http://localhost:3000/api/users
|
|
|
|
|
POST http://localhost:3000/api/users
|
|
|
|
|
GET http://localhost:3000/api/users/1
|
|
|
|
|
PUT http://localhost:3000/api/users/1
|
|
|
|
|
DELETE http://localhost:3000/api/users/1
|
|
|
|
|
```
|
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
以上示例,只用了 10 行左右的代码就创建了真实可用的 REST API 服务。除了内置的 REST API 以外,还可以通过 `app.actions()` 自定义其他操作,如登录、注册、注销等。
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-15 16:36:36 +00:00
|
|
|
|
app.actions({
|
2021-09-11 10:54:03 +00:00
|
|
|
|
async login(ctx, next) {},
|
|
|
|
|
async register(ctx, next) {},
|
|
|
|
|
async logout(ctx, next) {},
|
|
|
|
|
}, {
|
2021-09-15 16:36:36 +00:00
|
|
|
|
resourceName: 'users', // 属于 users 资源
|
2021-09-11 10:54:03 +00:00
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
以上自定义操作的 HTTP API 为:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
POST http://localhost:3000/api/users:login
|
|
|
|
|
POST http://localhost:3000/api/users:register
|
|
|
|
|
POST http://localhost:3000/api/users:logout
|
|
|
|
|
```
|
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
自定义的 HTTP API 依旧保持 REST API 的风格,以 `<resourceName>:<actionName>` 格式表示。实际上 REST API 也可以显式指定 `actionName`,当指定了 `actionName`,无所谓使用什么请求方法,如:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```bash
|
2021-09-15 16:36:36 +00:00
|
|
|
|
# 更新操作
|
|
|
|
|
PUT http://localhost:3000/api/users/1
|
|
|
|
|
# 等同于
|
2021-09-11 10:54:03 +00:00
|
|
|
|
POST http://localhost:3000/api/users:update/1
|
2021-09-15 16:36:36 +00:00
|
|
|
|
|
|
|
|
|
# 删除操作
|
|
|
|
|
DELETE http://localhost:3000/api/users/1
|
|
|
|
|
# 等同于
|
|
|
|
|
GET http://localhost:3000/api/users:destroy/1
|
|
|
|
|
# 等同于
|
2021-09-11 10:54:03 +00:00
|
|
|
|
POST http://localhost:3000/api/users:destroy/1
|
|
|
|
|
```
|
|
|
|
|
|

NocoBase 的路由(Resourcer)基于资源(Resource)和操作(Action)设计,将 REST 和 RPC 结合起来,提供更为灵活且统一的 Resource Action API。结合客户端 SDK 是这样的:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-15 16:36:36 +00:00
|
|
|
|
const { ClientSDK } = require('@nocobase/sdk');
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
const api = new ClientSDK({
|
|
|
|
|
// 可以适配不同 request
|
|
|
|
|
request(params) => Promise.resolve({}),
|
|
|
|
|
});
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-14 03:09:26 +00:00
|
|
|
|
await api.resource('users').list();
|
|
|
|
|
await api.resource('users').create();
|
|
|
|
|
await api.resource('users').get();
|
|
|
|
|
await api.resource('users').update();
|
|
|
|
|
await api.resource('users').destroy();
|
|
|
|
|
await api.resource('users').login();
|
|
|
|
|
await api.resource('users').register();
|
|
|
|
|
await api.resource('users').logout();
|
2021-09-11 10:54:03 +00:00
|
|
|
|
```

比如一个微型博客的表结构可以这样设计:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
// 用户
|
2021-09-14 03:09:26 +00:00
|
|
|
|
app.collection({
|
2021-09-11 10:54:03 +00:00
|
|
|
|
name: 'users',
|
2021-09-15 16:36:36 +00:00
|
|
|
|
schema: {
|
2021-09-16 07:57:21 +00:00
|
|
|
|

|
|
|
|
|
password: { type: 'password', unique: true },
|
|
|
|
|
posts: { type: 'hasMany' },
|
2021-09-15 16:36:36 +00:00

除了通过 `app.collection()` 配置 schema,也可以直接调用 api 插入或修改 schema,collection 的核心 API 有:
|
|
|
|
|
|
|
|
|
|
- `collection.schema` 当前 collection 的数据结构
|
|
|
|
|
- `schema.has()` 判断是否存在
|
|
|
|
|
- `schema.get()` 获取
|
|
|
|
|
- `schema.set()` 添加或更新
|
|
|
|
|
- `schema.merge()` 添加、或指定 key path 替换
|
|
|
|
|
- `schema.replace()` 替换
|
|
|
|
|
- `schema.delete()` 删除
|
2021-09-16 07:57:21 +00:00
|
|
|
|
- `collection.repository` 当前 collection 的数据仓库
|
|
|
|
|
- `repository.findAll()`
|
|
|
|
|
- `repository.findOne()`
|
|
|
|
|
- `repository.create()`
|
|
|
|
|
- `repository.update()`
|
|
|
|
|
- `repository.destroy()`
|
|
|
|
|
- `collection.model` 当前 collection 的数据模型

|
|
|
type: 'string',
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
// 移除
|
|
|
|
|
collection.schema.delete('content');
|
|
|
|
|
|
|
|
|
|
// 添加、或指定 key path 替换
|
|
|
|
|
collection.schema.merge({
|
|
|
|
|
content: {
|
|
|
|
|
type: 'content',
|
|
|
|
|
},
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
除了全局的 `db.sync()`,也有 `collection.sync()` 方法。
|
|
|
|
|
|
|
|
|
|
await collection.sync();
|
|
|
|
|
```

`db:sync` 是非常常用的命令行之一,数据库根据 collection 的 schema 生成表结构。更多详情见 CLI 章节。`db:sync` 之后,就可以往表里写入数据了,可以使用 Repository 或 Model 操作。

|
- Repository 初步提供了 findAll、findOne、create、update、destroy 核心操作方法。
|
|
|
|
|
- Model 为 Sequelize.Model,详细使用说明可以查看 Sequelize 文档。
|
|
|
|
|
- Model 取决于适配的 ORM,Repository 基于 Model 提供统一的接口。

通过 Repository 创建数据
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
const repository = app.db.getRepository('users');
|
|
|
|
|
|
|
|
|
|
const user = await repository.create({
|
|
|
|
|
title: 't1',
|
|
|
|
|
content: 'c1',
|
|
|
|
|
author: 1,
|
|
|
|
|
tags: [1,2,3],
|
|
|
|
|
}, {
|
|
|
|
|
whitelist: [],
|
|
|
|
|
blacklist: [],
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
await repository.findAll({
|
|
|
|
|
filter: {
|
|
|
|
|
title: 't1',
|
|
|
|
|
},
|
|
|
|
|
fields: ['id', 'title', 'content'],
|
|
|
|
|
sort: '-created_at',
|
|
|
|
|
page: 1,
|
|
|
|
|
perPage: 20,
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
await repository.findOne({
|
|
|
|
|
filter: {
|
|
|
|
|
title: 't1',
|
|
|
|
|
},
|
|
|
|
|
fields: ['id', 'title', 'content'],
|
|
|
|
|
sort: '-created_at',
|
|
|
|
|
page: 1,
|
|
|
|
|
perPage: 20,
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
await repository.update({
|
|
|
|
|
title: 't1',
|
|
|
|
|
content: 'c1',
|
|
|
|
|
author: 1,
|
|
|
|
|
tags: [1,2,3],
|
|
|
|
|
}, {
|
|
|
|
|
filter: {},
|
|
|
|
|
whitelist: [],
|
|
|
|
|
blacklist: [],
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
await repository.destroy({
|
|
|
|
|
filter: {},
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
通过 Model 创建数据
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
const User = db.getModel('users');
|
|
|
|
|
const user = await User.create({
|
|
|
|
|
title: 't1',
|
|
|
|
|
content: 'c1',
|
|
|
|
|
});
|
|
|
|
|
await user.updateAssociations({
|
|
|
|
|
author: 1,
|
|
|
|
|
tags: [1,2,3],
|
|
|
|
|
});

## 资源 & 操作 - Resource & Action
|
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
Resource 是互联网资源,互联网资源都对应一个地址。客户端请求资源地址,服务器响应请求,在这里「请求」就是一种「操作」,在 REST 里通过判断请求方法(GET/POST/PUT/DELETE)来识别具体的操作,但是请求方法局限性比较大,如上文提到的登录、注册、注销就无法用 REST API 的方式表示。为了解决这类问题,NocoBase 以 `<resourceName>:<actionName>` 格式表示资源的操作。在关系模型的世界里,关系无处不在,基于关系,NocoBase 又延伸了关系资源的概念,对应关系资源的操作的格式为 `<associatedName>.<resourceName>:<actionName>`。
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
Collection 会自动同步给 Resource,如上文 Collection 章节定义的 Schema,可以提炼的资源有:
|
2021-09-15 16:36:36 +00:00
|
|
|
|
|
|
|
|
|
- `users`
|
|
|
|
|
- `users.posts`
|
|
|
|
|
- `posts`
|
|
|
|
|
- `posts.tags`
|
|
|
|
|
- `posts.comments`
|
|
|
|
|
- `posts.author`
|
|
|
|
|
- `tags`
|
|
|
|
|
- `tags.posts`
|
|
|
|
|
- `comments`
|
|
|
|
|
- `comments.user`
|
|
|
|
|
|
|
|
|
|
<Alert title="Collection 和 Resource 的关系与区别" type="warning">
|
|
|
|
|
|
|
|
|
|
- Collection 定义数据的 schema(结构和关系)
|
|
|
|
|
- Resource 定义数据的 action(操作方法)
|
|
|
|
|
- Resource 请求和响应的数据结构由 Collection 定义
|
|
|
|
|
- Collection 默认自动同步给 Resource
|
|
|
|
|
- Resource 的概念更大,除了对接 Collection 以外,也可以对接外部数据或其他自定义
|
|
|
|
|
|
|
|
|
|
</Alert>
|
|
|
|
|
|
|
|
|
|
资源相关 API 有:
|
|
|
|
|
|
|
|
|
|
- `app.resource()`
|
|
|
|
|
- `app.actions()`
|
|
|
|
|
- `ctx.action`
|
|
|
|
|
|
|
|
|
|
一个资源可以有多个操作。
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
// 数据类
|
|
|
|
|
app.resource({
|
|
|
|
|
name: 'users',
|
|
|
|
|
actions: {
|
|
|
|
|
async list(ctx, next) {},
|
|
|
|
|
async get(ctx, next) {},
|
|
|
|
|
async create(ctx, next) {},
|
|
|
|
|
async update(ctx, next) {},
|
|
|
|
|
async destroy(ctx, next) {},
|
|
|
|
|
},
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
// 非数据类
|
|
|
|
|
app.resource({
|
|
|
|
|
name: 'server',
|
|
|
|
|
actions: {
|
|
|
|
|
// 获取服务器时间
|
|
|
|
|
getTime(ctx, next) {},
|
|
|
|
|
// 健康检测
|
|
|
|
|
healthCheck(ctx, next) {},
|
|
|
|
|
},
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
常规操作可以用于不同资源
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
app.actions({
|
|
|
|
|
async list(ctx, next) {},
|
|
|
|
|
async get(ctx, next) {},
|
|
|
|
|
async create(ctx, next) {},
|
|
|
|
|
async update(ctx, next) {},
|
|
|
|
|
async destroy(ctx, next) {},
|
|
|
|
|
}, {
|
|
|
|
|
// 不指定 resourceName 时,全局共享
|
|
|
|
|
resourceNames: ['posts', 'comments', 'users'],
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
在资源内部定义的 action 不会共享,常规类似增删改查的操作建议设置为全局,`app.resource()` 只设置参数,如:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-14 03:09:26 +00:00
|
|
|
|
app.resource({
|
2021-09-11 10:54:03 +00:00
|
|
|
|
name: 'users',
|
|
|
|
|
actions: {
|
|
|
|
|
list: {
|
|
|
|
|
fields: ['id', 'username'], // 只输出 id 和 username 字段
|
|
|
|
|
filter: {
|
|
|
|
|
'username.$ne': 'admin', // 数据范围筛选过滤 username != admin
|
|
|
|
|
},
|
|
|
|
|
sort: ['-created_at'], // 创建时间倒序
|
|
|
|
|
perPage: 50,
|
|
|
|
|
},
|
|
|
|
|
get: {
|
|
|
|
|
fields: ['id', 'username'], // 只输出 id 和 username 字段
|
|
|
|
|
filter: {
|
|
|
|
|
'username.$ne': 'admin', // 数据范围筛选过滤 username != admin
|
|
|
|
|
},
|
|
|
|
|
},
|
|
|
|
|
create: {
|
|
|
|
|
fields: ['username'], // 白名单
|
|
|
|
|
},
|
|
|
|
|
update: {
|
|
|
|
|
fields: ['username'], // 白名单
|
|
|
|
|
},
|
|
|
|
|
destroy: {
|
|
|
|
|
filter: { // 不能删除 admin
|
|
|
|
|
'username.$ne': 'admin',
|
|
|
|
|
},
|
|
|
|
|
},
|
|
|
|
|
},
|
|
|
|
|
});
|
2021-09-15 16:36:36 +00:00
|
|
|
|
|
|
|
|
|
// app 默认已经内置了 list, get, create, update, destroy 操作
|
|
|
|
|
app.actions({
|
|
|
|
|
async list(ctx, next) {},
|
|
|
|
|
async get(ctx, next) {},
|
|
|
|
|
async create(ctx, next) {},
|
|
|
|
|
async update(ctx, next) {},
|
|
|
|
|
async destroy(ctx, next) {},
|
|
|
|
|
});
|
2021-09-11 10:54:03 +00:00
|
|
|

在 Middleware Handler 和 Action Handler 里,都可以通过 `ctx.action` 获取到当前 action 实例,提供了两个非常有用的 API:
|
|
|
|
|
|
|
|
|
|
- `ctx.action.params`:获取操作对应的参数
|
|
|
|
|
- `ctx.action.mergeParams()`:处理多来源参数合并
|
|
|
|
|
|
|
|
|
|
`ctx.action.params` 有:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
- 定位资源和操作
|
|
|
|
|
- `actionName`
|
|
|
|
|
- `resourceName`
|
|
|
|
|
- `associatedName`
|
|
|
|
|
- 定位资源 ID
|
|
|
|
|
- `resourceId`
|
|
|
|
|
- `associatedId`
|
|
|
|
|
- request query
|
|
|
|
|
- `filter`
|
|
|
|
|
- `fields`
|
|
|
|
|
- `sort`
|
|
|
|
|
- `page`
|
|
|
|
|
- `perPage`
|
|
|
|
|
- 其他 query 值
|
|
|
|
|
- request body
|
|
|
|
|
- `values`

|
|
|
|
示例:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
async function (ctx, next) {
|
|
|
|
|
const { resourceName, resourceId, filter, fields } = ctx.action.params;
|
|
|
|
|
// ...
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
`ctx.action.mergeParams()` 主要用于多来源参数合并,以 `filter` 参数为例。如:客户端请求日期 2021-09-15 创建的文章
|
2021-09-15 16:36:36 +00:00
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
GET /api/posts:list?filter={"created_at": "2021-09-15"}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
资源设置锁定只能查看已发布的文章
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
app.resource({
|
|
|
|
|
name: 'posts',
|
|
|
|
|
actions: {
|
|
|
|
|
list: {
|
|
|
|
|
filter: { status: 'publish' }, // 只能查看已发布文章
|
|
|
|
|
},
|
|
|
|
|
},
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
权限设定,只能查看自己创建的文章
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
app.use(async (ctx, next) => {
|
|
|
|
|
const { resourceName, actionName } = ctx.action.params;
|
|
|
|
|
if (resourceName === 'posts' && actionName === 'list') {
|
|
|
|
|
ctx.action.mergeParams({
|
|
|
|
|
filter: {
|
|
|
|
|
created_by_id: ctx.state.currentUser.id,
|
|
|
|
|
},
|
|
|
|
|
});
|
|
|
|
|
}
|
|
|
|
|
await next();
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
以上客户端、资源配置、中间件内我们都指定了 filter 参数,三个来源的参数最终会合并在一起作为最终的过滤条件:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
async function list(ctx, next) {
|
|
|
|
|
// list 操作中获取到的 filter
|
|
|
|
|
console.log(ctx.params.filter);
|
2021-09-16 07:57:21 +00:00
|
|
|
|
// filter 是特殊的 and 合并
|
2021-09-15 16:36:36 +00:00
|
|
|
|
// {
|
|
|
|
|
// and: [
|
|
|
|
|
// { created_at: '2021-09-15' },
|
|
|
|
|
// { status: 'publish' },
|
|
|
|
|
// { created_by_id: 1, }
|
|
|
|
|
// ]
|
|
|
|
|
// }
|
|
|
|
|
}
|
|
|
|
|
```

## 事件 - Event
|
|
|
|
|
|
2021-09-14 03:09:26 +00:00
|
|
|
|
在操作执行前、后都放置了相关事件监听器,可以通过 `app.db.on()` 和 `app.on()` 添加。区别在于:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-14 03:09:26 +00:00
|
|
|
|
- `app.db.on()` 添加数据库层面的监听器
|
|
|
|
|
- `app.on()` 添加服务器应用层面的监听器
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-14 03:09:26 +00:00
|
|
|
|
以 `users:login` 为例,在数据库里为「查询」操作,在应用里为「登录」操作。也就是说,如果需要记录登录操作日志,要在 `app.on()` 里处理。
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
// 创建数据时,执行 User.create() 时触发
|
2021-09-15 16:36:36 +00:00
|
|
|
|
app.db.on('users.beforeCreate', async (model) => {});
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
// 客户端 `POST /api/users:login` 时触发
|
2021-09-15 16:36:36 +00:00
|
|
|
|
app.on('users.beforeLogin', async (ctx, next) => {});
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
// 客户端 `POST /api/users` 时触发
|
2021-09-15 16:36:36 +00:00
|
|
|
|
app.on('users.beforeCreate', async (ctx, next) => {});
|
2021-09-11 10:54:03 +00:00
|

## 中间件 - Middleware
|
|
|
|
|
|
2021-09-14 03:09:26 +00:00
|
|
|
|
Server Application 基于 Koa,所有 Koa 的插件(中间件)都可以直接使用,可以通过 `app.use()` 添加。如:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-14 03:09:26 +00:00
|
|
|
|
const responseTime = require('koa-response-time');
|
|
|
|
|
app.use(responseTime());
|
|
|
|
|
|
|
|
|
|
app.use(async (ctx, next) => {
|
|
|
|
|
await next();
|
2021-09-11 10:54:03 +00:00
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
与 `koa.use(middleware)` 略有不同,`app.use(middleware, options)` 多了个 options 参数,可以用于限定 resource 和 action,也可以用于控制中间件的插入位置。
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { middleware } from '@nocobase/server';
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
app.use(async (ctx, next) => {}, {
|
2021-09-11 10:54:03 +00:00
|
|
|
|
name: 'middlewareName1',
|
2021-09-16 07:57:21 +00:00
|
|
|
|
resourceNames: [], // 作用于资源内所有 actions
|
|
|
|
|
actionNames: [
|
|
|
|
|
'list', // 全部 list action
|
|
|
|
|
'users:list', // 仅 users 资源的 list action,
|
|
|
|
|
],
|
2021-09-11 10:54:03 +00:00
|
|
|
|
insertBefore: '',
|
|
|
|
|
insertAfter: '',
|
2021-09-16 07:57:21 +00:00
|
|
|
|
});
|
2021-09-11 10:54:03 +00:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 命令行 - CLI
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
Application 除了可以做 HTTP Server 以外,也是 CLI(内置了 Commander)。目前内置的命令有:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
- `init` 初始化
|
|
|
|
|
- `db:sync --force` 用于配置与数据库表结构同步
|
2021-09-11 10:54:03 +00:00
|
|
|
|
- `start --port` 启动应用
|
2021-09-16 07:57:21 +00:00
|
|
|
|
- `plugin:**` 插件相关
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
自定义:
|
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-14 03:09:26 +00:00
|
|
|
|
app.command('foo').action(async () => {
|
2021-09-11 10:54:03 +00:00
|
|
|
|
console.log('foo...');
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 插件 - Plugin
|
|
|
|
|
|
|
|
|
|
上文,讲述了核心的扩展接口,包括但不局限于:
|
|
|
|
|
|
|
|
|
|
- Database/Collection
|
2021-09-14 03:09:26 +00:00
|
|
|
|
- `app.db` database 实例
|
2021-09-15 16:36:36 +00:00
|
|
|
|
- `app.collection()` 等同于 `app.db.collection()`
|
2021-09-11 10:54:03 +00:00
|
|
|
|
- Resource/Action
|
2021-09-14 03:09:26 +00:00
|
|
|
|
- `app.resource()` 等同于 `app.resourcer.define()`
|
2021-09-15 16:36:36 +00:00
|
|
|
|
- `app.actions()` 等同于 `app.resourcer.registerActions()`
|
2021-09-11 10:54:03 +00:00
|
|
|
|
- Hook/Event
|
2021-09-14 03:09:26 +00:00
|
|
|
|
- `app.on()` 添加服务器监听器
|
|
|
|
|
- `app.db.on()` 添加数据库监听器
|
2021-09-11 10:54:03 +00:00
|
|
|
|
- Middleware
|
2021-09-14 03:09:26 +00:00
|
|
|
|
- `app.use()` 添加中间件
|
2021-09-11 10:54:03 +00:00
|
|
|
|
- CLI
|
2021-09-14 03:09:26 +00:00
|
|
|
|
- `app.cli` commander 实例
|
|
|
|
|
- `app.command()` 等同于 `app.cli.command()`
|
|
|
|
|
|
2021-09-16 07:57:21 +00:00
|
|
|
|
基于以上扩展接口,进一步提供了模块化、可插拔的插件,可以通过 `app.plugin()` 添加。插件的流程包括安装、升级、激活、载入、禁用、卸载,不需要的流程可缺失。如:
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
**最简单的插件**
|
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-14 03:09:26 +00:00
|
|
|
|
app.plugin(function pluginName1() {
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
2021-09-15 16:36:36 +00:00
|
|
|
|
这种方式添加的插件会直接载入,无需安装。

## 测试 - Testing
|
|
|
|
|
|
|
|
|
|
有代码就需要测试,@nocobase/test 提供了 mockDatabase 和 mockServer 用于数据库和服务器的测试,如:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { mockServer, MockServer } from '@nocobase/test';
|
|
|
|
|
|
|
|
|
|
describe('mock server', () => {
|
|
|
|
|
let api: MockServer;
|
|
|
|
|
|
|
|
|
|
beforeEach(() => {
|
|
|
|
|
api = mockServer({
|
|
|
|
|
dataWrapping: false,
|
|
|
|
|
});
|
2021-09-15 16:36:36 +00:00
|
|
|
|
api.actions({
|
2021-09-11 10:54:03 +00:00
|
|
|
|
list: async (ctx, next) => {
|
|
|
|
|
ctx.body = [1, 2];
|
|
|
|
|
await next();
|
|
|
|
|
},
|
|
|
|
|
});
|
|
|
|
|
api.resource({
|
|
|
|
|
name: 'test',
|
|
|
|
|
});
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
afterEach(async () => {
|
|
|
|
|
return api.destroy();
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
it('agent.get', async () => {
|
|
|
|
|
const response = await api.agent().get('/test');
|
|
|
|
|
expect(response.body).toEqual([1, 2]);
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
it('agent.resource', async () => {
|
|
|
|
|
const response = await api.agent().resource('test').list();
|
|
|
|
|
expect(response.body).toEqual([1, 2]);
|
|
|
|
|
});
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 客户端 - Client
|
|
|
|
|
|
|
|
|
|
为了让更多非开发人员也能参与进来,NocoBase 提供了配套的客户端插件 —— 无代码的可视化配置界面。客户端插件需要与 @nocobase/client 配合使用,可以直接使用,也可以自行改造。
|
|
|
|
|
|
|
|
|
|
插件配置
|
|
|
|
|
|
|
|
|
|
```ts
|
2021-09-14 03:09:26 +00:00
|
|
|
|
app.plugin('@nocobase/plugin-client', {
|
2021-09-11 10:54:03 +00:00
|
|
|
|
// 自定义 dist 路径
|
|
|
|
|
dist: path.resolve(__dirname, './node_modules/@nocobase/client/app'),
|
|
|
|
|
});
|

可以自行扩展组件,以上组件基于 Formily 构建,怎么自定义组件大家查看相关组件源码或 Formily 文档,这里说点不一样的。
|
2021-09-11 10:54:03 +00:00
|
|
|
|
|
|
|
|
|
- 如何扩展数据库字段?
|
|
|
|
|
- 如何将第三方区块添加到 AddNew 模块中?
|
|
|
|
|
- 如何在操作栏里添加更多的内置操作?
|
|
|
|
|
- 如何自定义配置工具栏?
|
|
|
|
|
|
|
|
|
|
除了组件具备灵活的扩展以外,客户端也可以在任意前端框架中使用,可以自定义 Request 和 Router,如:
|
|
|
|
|
|
|
|
|
|
<pre lang="tsx">
|
|
|
|
|
import React from 'react';
