## 启用方式
|
|
|
|
这是一个示例，在指定的路由上启用`uri blocker`插件：
|
|
|
|
```shell
|
|
curl -i http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"uri": "/*",
|
|
"plugins": {
|
|
"uri-blocker": {
|
|
"block_rules": ["root.exe", "root.m+"]
|
|
}
|
|
},
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"127.0.0.1:1980": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
## 测试插件
|
|
|
|

|
|
```
|
|
|
|
## 禁用插件
|
|
|
|
当想禁用`uri blocker`插件时，非常简单，只需要在插件配置中删除相应的 json 配置，无需重启服务，即可立即生效：
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"uri": "/*",
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"127.0.0.1:1980": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
`uri blocker` 插件现在已被禁用，它也适用于其他插件。
