Some plugins will register API to serve their purposes.
|
||||
|
||||
Since these API are not added as regular [Route](admin-api.md), we can't add
|
||||
plugins to protect them. To solve the problem, we add a new concept called 'interceptors'
|
||||
to run rules to protect them.
|
||||
|
||||
Here is an example to limit the access of `/apisix/prometheus/metrics` (a route introduced via plugin prometheus)
|
||||
to clients in `10.0.0.0/24`:
|
||||
|
||||
```shell
|
||||
$ curl http://127.0.0.1:9080/apisix/admin/plugin_metadata/prometheus -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -i -X PUT -d '
|
||||
{
|
||||
"interceptors": [
|
||||
{
|
||||
"name": "ip-restriction",
|
||||
"conf": {
|
||||
"whitelist": ["10.0.0.0/24"]
|
||||
}
|
||||
}
|
||||
]
|
||||
}'
|
||||
```
|
||||
|
||||
You can see that the interceptors are configured like the plugins. The `name` is
|
||||
the name of plugin which you want to run and the `conf` is the configuration of the
|
||||
plugin.
|
||||
|
||||
Currently we only support a subset of plugins which can be run as interceptors.
|
||||
|
||||

## Summary
|
||||
|

- [**Description**](#description)
|
||||
- [**Attributes**](#attributes)
|
||||
- [**Example**](#example)
|
||||
|
||||
## Description
|
||||
|
||||
The `public-api` plugin is used to enhance the plugin public API access control.
|
||||
When current users develop custom plugins, they can register some public APIs for fixed functionality, such as the `/apisix/plugin/jwt/sign` API in `jwt-auth`. These APIs can only apply limited plugins for access control (currently only `ip-restriction`) by way of plugin interceptors.
|
||||
|
||||
With the `public-api` plugin, we put all public APIs into the general HTTP API router, which is consistent with the normal Route registered by the user and can apply any plugin. The public API added in the user plugin is no longer expose by default by APISIX, and the user has to manually configure the Route for it, the user can configure any uri and plugin.
|
||||
|
||||
## Attributes
|
||||
|
||||
| Name | Type | Requirement | Default | Valid | Description |
|
||||
| -- | -- | -- | -- | -- | -- |
|
||||
| uri | string | optional | "" | | The uri of the public API. When you set up the route, you can use this to configure the original API uri if it is used in a way that is inconsistent with the original public API uri. |
|
||||
|
||||
## Example
|
||||
|
||||
We take the `jwt-auth` token sign API as an example to show how to configure the `public-api` plugin. Also, the `key-auth` will be used to show how to configure the protection plugin for the public API.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
The use of key-auth and jwt-auth requires the configuration of a consumer that contains the configuration of these plugins, and you need to create one in advance, the process will be omitted here.
|
||||
|
||||
### Basic Use Case
|
||||
|
||||
First we will setup a route.
|
||||
|
||||
```shell
|
||||
$ curl -X PUT 'http://127.0.0.1:9080/apisix/admin/routes/r1' \
|
||||
-H 'X-API-KEY: <api-key>' \
|
||||
-H 'Content-Type: application/json' \
|
||||
-d '{
|
||||
"uri": "/apisix/plugin/jwt/sign",
|
||||
"plugins": {
|
||||
"public-api": {}
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
Let's test it.
|
||||
|
||||
```shell
|
||||
$ curl 'http://127.0.0.1:9080/apisix/plugin/jwt/sign?key=user-key'
|
||||
```
|
||||
|
||||
It will respond to a text JWT.
|
||||
|
||||
### Customize URI
|
||||
|
||||
Let's setup another route.
|
||||
|
||||
```shell
|
||||
$ curl -X PUT 'http://127.0.0.1:9080/apisix/admin/routes/r2' \
|
||||
-H 'X-API-KEY: <api-key>' \
|
||||
-H 'Content-Type: application/json' \
|
||||
-d '{
|
||||
"uri": "/gen_token",
|
||||
"plugins": {
|
||||
"public-api": {
|
||||
"uri": "/apisix/plugin/jwt/sign"
|
||||
}
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
Let's test it.
|
||||
|
||||
```shell
|
||||
$ curl 'http://127.0.0.1:9080/gen_token?key=user-key'
|
||||
```
|
||||
|
||||
It will still respond to a text JWT. We can see that users are free to configure URI for the public API to match.
|
||||
|
||||
### Protect Route
|
||||
|
||||
Let's modify the last route and add `key-auth` authentication to it.
|
||||
|
||||
```shell
|
||||
$ curl -X PUT 'http://127.0.0.1:9080/apisix/admin/routes/r2' \
|
||||
-H 'X-API-KEY: <api-key>' \
|
||||
-H 'Content-Type: application/json' \
|
||||
-d '{
|
||||
"uri": "/gen_token",
|
||||
"plugins": {
|
||||
"public-api": {
|
||||
"uri": "/apisix/plugin/jwt/sign"
|
||||
},
|
||||
"key-auth": {}
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
Let's test it.
|
||||
|
||||
```shell
|
||||
$ curl -i 'http://127.0.0.1:9080/gen_token?key=user-key'
|
||||
-H "apikey: test-apikey"
|
||||
HTTP/1.1 200 OK
|
||||
|
||||
# Failed request
|
||||
$ curl -i 'http://127.0.0.1:9080/gen_token?key=user-key'
|
||||
HTTP/1.1 401 UNAUTHORIZED
|
||||
```
|
||||
|
||||
It will still respond to a text JWT. If we don't add `apikey` to the request header, it will respond with a 401 block request. In this way, we have implemented a plugin approach to protect the public API.

有些插件为实现它的功能会注册额外的接口。
|
||||
|
||||
由于这些接口不是通过 admin API 添加的，所以没办法像管理 Route 那样管理它们。为了能够保护这些接口不被利用，我们引入了 interceptors 的概念。
|
||||
|
||||
下面是通过 interceptors 来保护由 prometheus 插件引入的 `/apisix/prometheus/metrics` 接口，限定只能由 `10.0.0.0/24` 网段的用户访问：
|
||||
|
||||
```shell
|
||||
$ curl http://127.0.0.1:9080/apisix/admin/plugin_metadata/prometheus -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -i -X PUT -d '

|
||||
}
|
||||
}
|
||||
]
|
||||
}'
|
||||
```
|
||||
|
||||
我们能看到配置 interceptors 就像配置 plugin 一样：name 是 interceptor 的名称，而 conf 是它的配置。
|
||||
|
||||
当前我们只支持一部分插件作为 interceptor 运行。
