# Overview
|
|
|
|
HTTP API of NocoBase is designed based on Resource & Action, a superset of REST API. The operation includes but not limited to create, read, update and delete. Resource Action can be extended arbitrarily in NocoBase.
|
|
|
|
## Resource
|
|
|
|
In NocoBase, resource has two expressions:
|
|
|
|
- `<collection>`
|
|
- `<collection>.<association>`
|
|
|
|
<Alert>
|
|
|
|
- Collection is the set of all abstract data
|
|
- Association is the associated data of collection
|
|
- Resource includes both collection and collection.association
|
|
|
|
</Alert>
|
|
|
|
### Example
|
|
|
|
- `posts` Post
|
|
- `posts.user` Post user
|
|
- `posts.tags` Post tags
|
|
|
|
## Action
|
|
|
|
Action on resource is expressed by `:<action>`
|
|
|
|
- `<collection>:<action>`
|
|
- `<collection>.<association>:<action>`
|
|
|
|
Built-in global actions for collection or association:
|
|
|
|
- `create`
|
|
- `get`
|
|
- `list`
|
|
- `update`
|
|
- `destroy`
|
|
- `move`
|
|
|
|
Built-in association actions for association only:
|
|
|
|
- `set`
|
|
- `add`
|
|
- `remove`
|
|
- `toggle`
|
|
|
|
### Example
|
|
|
|
- `posts:create` Create post
|
|
- `posts.user:get` Get post user
|
|
- `posts.tags:add` Add tags to post (associate existing tags with post)
|
|
|
|
## Request URL
|
|
|
|
```bash
|
|
<GET|POST> /api/<collection>:<action>
|
|
<GET|POST> /api/<collection>:<action>/<collectionIndex>
|
|
<GET|POST> /api/<collection>/<collectionIndex>/<association>:<action>
|
|
<GET|POST> /api/<collection>/<collectionIndex>/<association>:<action>/<associationIndex>
|
|
```
|
|
|
|
### Example
|
|
|
|
posts resource
|
|
|
|
```bash
|
|
POST /api/posts:create
|
|
GET /api/posts:list
|
|
GET /api/posts:get/1
|
|
POST /api/posts:update/1
|
|
POST /api/posts:destroy/1
|
|
```
|
|
|
|
posts.comments resource
|
|
|
|
```bash
|
|
POST /api/posts/1/comments:create
|
|
GET /api/posts/1/comments:list
|
|
GET /api/posts/1/comments:get/1
|
|
POST /api/posts/1/comments:update/1
|
|
POST /api/posts/1/comments:destroy/1
|
|
```
|
|
|
|
posts.tags resource
|
|
|
|
```bash
|
|
POST /api/posts/1/tags:create
|
|
GET /api/posts/1/tags:get
|
|
GET /api/posts/1/tags:list
|
|
POST /api/posts/1/tags:update
|
|
POST /api/posts/1/tags:destroy
|
|
POST /api/posts/1/tags:add
|
|
GET /api/posts/1/tags:remove
|
|
```
|
|
|
|
## Locate Resource
|
|
|
|
- Collection resource locates the data to be processed by `collectionIndex`, `collectionIndex` must be unique.
|
|
- Association resource locates the data to be processed by `collectionIndex` and `associationIndex` jointly, `associationIndex` may not be unique, but the joint index of `collectionIndex` and `associationIndex` must be unique.
|
|
|
|
When viewing details of association resource, the requested URL needs to provide both `<collectionIndex>` and `<associationIndex>`, `<collectionIndex>` is necessary as `<associationIndex>` may not be unique.
|
|
|
|
For example, `tables.fields` represents the fields of a data table:
|
|
|
|
```bash
|
|
GET /api/tables/table1/fields/title
|
|
GET /api/tables/table2/fields/title
|
|
```
|
|
|
|
Both table1 and table2 have the title field, title is unique in one table, but other tables may also have fields of that name.
|
|
|
|
