## Name
The plugin helps we intercept user requests, we only need to indicate the `block_rules`.
## Attributes
| Name | Type | Requirement | Default | Valid | Description |
| ------------- | ------------- | ----------- | ------- | ---------- | --------------------------------------------------------------------------- |
| block_rules | array[string] | required | | | Regular filter rule array. Each of these items is a regular rule. If the current request URI hits any one of them, set the response code to rejected_code to exit the current user request. Example: `["root.exe", "root.m+"]`. |
| rejected_code | integer | optional | 403 | [200, ...] | The HTTP status code returned when the request URI hit any of `block_rules` |
## How To Enable
Here's an example, enable the `uri blocker` plugin on the specified route:
```shell
curl -i http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{

"plugins": {
"uri-blocker": {
"block_rules": ["root.exe", "root.m+"]
}

}
}
}'
```

## Disable Plugin
When you want to disable the `uri blocker` plugin, it is very simple, you can delete the corresponding json configuration in the plugin configuration, no need to restart the service, it will take effect immediately:
```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
}
}
}'
```
The `uri blocker` plugin has been disabled now. It works for other plugins.
