## 名字
`referer-restriction` 插件可以根据 Referer 请求头限制访问。
## 属性
| 参数名 | 类型 | 可选项 | 默认值 | 有效值 | 描述 |
| --------- | ------------- | ------ | ------ | ------ | -------------------------------- |
| whitelist | array[string] | 必须 | | | 域名列表。域名开头可以用'*'作为通配符 |
| bypass_missing | boolean | 可选 | false | | 当 Referer 不存在或格式有误时,是否绕过检查 |
## 如何启用
下面是一个示例,在指定的 route 上开启了 `referer-restriction` 插件:
```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": {
"referer-restriction": {
"bypass_missing": true,
"whitelist": [
"xx.com",
"*.xx.com"
]
}
}
}'
```
## 测试插件
`Referer: http://xx.com/x` 请求:
```shell
$ curl http://127.0.0.1:9080/index.html -H 'Referer: http://xx.com/x'
HTTP/1.1 200 OK
...
```
`Referer: http://yy.com/x` 请求:
```shell
$ curl http://127.0.0.1:9080/index.html -H 'Referer: http://yy.com/x'
HTTP/1.1 403 Forbidden
...
{"message":"Your referer host is not allowed"}
```
不带 `Referer` 请求:
```shell
$ curl http://127.0.0.1:9080/index.html
HTTP/1.1 200 OK
...
```
## 禁用插件
当你想去掉 `referer-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://127.0.0.1:2379/v2/keys/apisix/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d value='
{
"uri": "/index.html",
"plugins": {},
"upstream": {
"type": "roundrobin",
"nodes": {
"39.97.63.215:80": 1
}
}
}'
```
现在就已移除 `referer-restriction` 插件,其它插件的开启和移除也类似。
