## 简介
|
||
|
||
`consumer-restriction` 根据选择的不同对象做相应的访问限制。
|
||
|
||
## 属性
|
||
|
||
| 参数名 | 类型 | 可选项 | 默认值 | 有效值 | 描述 |
|
||
| --------- | ------------- | ------ | -----------------| --------------------------------| ----------------------------------------------------------|
|
||
| type | string | 可选 | consumer_name | ["consumer_name", "service_id"] | 根据不同的对象做相应的限制,支持 `consumer_name`、`service_id`。 |
|
||
| whitelist | array[string] | 必选 | | | 与`blacklist`二选一，只能单独启用白名单或黑名单，两个不能一起使用。 |
|
||
| blacklist | array[string] | 必选 | | | 与`whitelist`二选一，只能单独启用白名单或黑名单，两个不能一起使用。 |
|
||
| rejected_code | integer | 可选 | 403 | [200,...] | 当请求被拒绝时，返回的 HTTP 状态码。|
|
||
|
||
对于 `type` 字段是个枚举类型，它可以是 `consumer_name` 或 `service_id` 。分别代表以下含义：
|
||
|
||
* **consumer_name**：把 `consumer` 的 `username` 列入白名单或黑名单（支持单个或多个 consumer）来限制对服务或路线的访问。
|
||
* **service_id**：把 `service` 的 `id` 列入白名单或黑名单（支持一个或多个 service）来限制service的访问，需要结合授权插件一起使用。
|
||
|
||
## 示例
|
||
|
||
### 如何限制 `consumer_name`
|
||
|
||
下面是一个示例，在指定的 route 上开启了 `consumer-restriction` 插件，限制 consumer 访问:
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
|
||
{
|
||
"username": "jack1",
|
||
"plugins": {
|
||
"basic-auth": {
|
||
"username":"jack2019",
|
||
"password": "123456"
|
||
}
|
||
}
|
||
}'
|
||
|
||
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
|
||
{
|
||
"username": "jack2",
|
||
"plugins": {
|
||
"basic-auth": {
|
||
"username":"jack2020",
|
||
"password": "123456"
|
||
}
|
||
}
|
||
}'
|
||
|
||
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"uri": "/index.html",
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
}
|
||
},
|
||
"plugins": {
|
||
"basic-auth": {},
|
||
"consumer-restriction": {
|
||
"whitelist": [
|
||
"jack1"
|
||
]
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
**测试插件**
|
||
|
||
jack1 访问:
|
||
|
||
```shell
|
||
curl -u jack2019:123456 http://127.0.0.1:9080/index.html -i
|
||
HTTP/1.1 200 OK
|
||
...
|
||
```
|
||
|
||
jack2 访问:
|
||
|
||
```shell
|
||
curl -u jack2020:123456 http://127.0.0.1:9080/index.html -i
|
||
HTTP/1.1 403 Forbidden
|
||
...
|
||
{"message":"The consumer_name is forbidden."}
|
||
```
|
||
|
||
### 如何限制 `service_id`
|
||
|
||
`service_id`方式需要与授权插件一起配合使用，这里以key-auth授权插件为例。
|
||
|
||
1、创建两个 service
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/services/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"upstream": {
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
},
|
||
"type": "roundrobin"
|
||
},
|
||
"desc": "new service 001"
|
||
}'
|
||
|
||
curl http://127.0.0.1:9080/apisix/admin/services/2 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"upstream": {
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
},
|
||
"type": "roundrobin"
|
||
},
|
||
"desc": "new service 002"
|
||
}'
|
||
```
|
||
|
||
2、在 `consumer` 上绑定 `consumer-restriction` 插件(需要与一个授权插件配合才能绑定),并添加 `service_id` 白名单列表
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"username": "new_consumer",
|
||
"plugins": {
|
||
"key-auth": {
|
||
"key": "auth-jack"
|
||
},
|
||
"consumer-restriction": {
|
||
"type": "service_id",
|
||
"whitelist": [
|
||
"1"
|
||
],
|
||
"rejected_code": 403
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
3、在 route 上开启 `key-auth` 插件并绑定 `service_id` 为`1`
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"uri": "/index.html",
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
}
|
||
},
|
||
"service_id": 1,
|
||
"plugins": {
|
||
"key-auth": {
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
**测试插件**
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/index.html -H 'apikey: auth-jack' -i
|
||
HTTP/1.1 200 OK
|
||
...
|
||
```
|
||
|
||
说明在白名单列中的 `service_id` 允许访问，插件配置生效。
|
||
|
||
4、在 route 上开启 `key-auth` 插件并绑定 `service_id` 为`2`
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"uri": "/index.html",
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
}
|
||
},
|
||
"service_id": 2,
|
||
"plugins": {
|
||
"key-auth": {
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
**测试插件**
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/index.html -H 'apikey: auth-jack' -i
|
||
HTTP/1.1 403 Forbidden
|
||
...
|
||
{"message":"The service_id is forbidden."}
|
||
```
|
||
|
||
说明不在白名单列表的 `service_id` 被拒绝访问，插件配置生效。
|
||
|
||
## 禁用插件
|
||
|
||
当你想去掉 `consumer-restriction` 插件的时候，很简单，在插件的配置中把对应的 json 配置删除即可，无须重启服务，即刻生效：
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"uri": "/index.html",
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
}
|
||
},
|
||
"plugins": {
|
||
"basic-auth": {}
|
||
}
|
||
}'
|
||
```
|
||
|
||
现在就已移除 `consumer-restriction` 插件，其它插件的开启和移除也类似。
