## 如何启用
|
|
|
|
|
|
|
|
|
|
|
|
下面是一个示例，在指定的 route 上开启了 mqtt-proxy 插件:
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
curl http://127.0.0.1:9080/apisix/admin/stream_routes/1 -X PUT -d '
|
|
|
|
|
|
{
|
|
|
|
|
|
"remote_addr": "127.0.0.1",
|
|
|
|
|
|
"plugins": {
|
|
|
|
|
|
"mqtt-proxy": {
|
|
|
|
|
|
"protocol_name": "MQTT",
|
|
|
|
|
|
"protocol_level": 4,
|
|
|
|
|
|
"upstream": {
|
|
|
|
|
|
"ip": "127.0.0.1",
|
|
|
|
|
|
"port": 1980
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
}'
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
#### 禁用插件
|
|
|
|
|
|
|
|
|
|
|
|
当你想去掉插件的时候，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://127.0.0.1:2379/v2/keys/apisix/stream_routes/1 -X DELETE
|
|
|
|
|
|
```
