## 名字
`key-auth` 是一个认证插件,它需要与 `consumer` 一起配合才能工作。
添加 Key Authentication 到一个 `service``route`。 然后,`consumer` 将其密钥添加到查询字符串参数或标头中以验证其请求。
## 属性
| 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 |
| ---- | ------ | ------ | ------ | ------ | ------------------------------------------------------------------------------------------------------------- |
| key | string | 可选 | | | 不同的 `consumer` 对象应有不同的值,它应当是唯一的。不同 consumer 使用了相同的 `key` ,将会出现请求匹配异常。 |
## 如何启用
1. 创建一个 consumer 对象,并设置插件 `key-auth` 的值。
```shell
curl http://127.0.0.1:9180/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"username": "jack",
"plugins": {
"key-auth": {
"key": "auth-one"
}
}
}'
```
你可以使用浏览器打开 dashboard`http://127.0.0.1:9080/apisix/dashboard/`,通过 web 界面来完成上面的操作,先增加一个 consumer

然后在 consumer 页面中添加 key-auth 插件:

2. 创建 route 或 service 对象,并开启 `key-auth` 插件。
```shell
curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"methods": ["GET"],
"uri": "/index.html",
"id": 1,
"plugins": {
"key-auth": {}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"39.97.63.215:80": 1
}
}
}'
```
## 测试插件
下面是一个正常通过 `key-auth` 验证的请求:
```shell
$ curl http://127.0.0.2:9080/index.html -H 'apikey: auth-one' -i
HTTP/1.1 200 OK
...
```
如果当前请求没有正确设置 `apikey` ,将得到一个 `401` 的应答。
```shell
$ curl http://127.0.0.2:9080/index.html -i
HTTP/1.1 401 Unauthorized
...
{"message":"Missing API key found in request"}
$ curl http://127.0.0.2:9080/index.html -H 'apikey: abcabcabc' -i
HTTP/1.1 401 Unauthorized
...
{"message":"Invalid API key in request"}
```
## 禁用插件
当你想去掉 `key-auth` 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 -X PUT -d value='
{
"methods": ["GET"],
"uri": "/index.html",
"id": 1,
"plugins": {
},
"upstream": {
"type": "roundrobin",
"nodes": {
"39.97.63.215:80": 1
}
}
}'
```
现在就已经移除了该插件配置,其他插件的开启和移除也是同样的方法。
