## 名字

`basic-auth` 是一个认证插件，它需要与 `consumer` 一起配合才能工作。

添加 Basic Authentication 到一个 `service` 或 `route`。 然后 `consumer` 将其用户名和密码添加到请求头中以验证其请求。

有关 Basic Authentication 的更多信息，可参考 [维基百科](https://zh.wikipedia.org/wiki/HTTP%E5%9F%BA%E6%9C%AC%E8%AE%A4%E8%AF%81) 查看更多信息。

## 属性

| 名称     | 类型   | 必选项 | 默认值 | 有效值 | 描述                                                                                                               |
| -------- | ------ | ------ | ------ | ------ | ------------------------------------------------------------------------------------------------------------------ |
| username | string | 必须   |        |        | 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 `username` ，将会出现请求匹配异常。 |
| password | string | 必须   |        |        | 用户的密码                                                                                                         |

## 如何启用

### 1. 创建一个 consumer 对象，并设置插件 `basic-auth` 的值。

```shell
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "username": "foo",
    "plugins": {
        "basic-auth": {
            "username": "foo",
            "password": "bar"
        }
    }
}'
```

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：

![auth-1](../../../assets/images/plugin/basic-auth-1.png)

然后在 consumer 页面中添加 basic-auth 插件：

![auth-2](../../../assets/images/plugin/basic-auth-2.png)

### 2. 创建 Route 或 Service 对象，并开启 `basic-auth` 插件。

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "methods": ["GET"],
    "uri": "/hello",
    "plugins": {
        "basic-auth": {}
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:8080": 1
        }
    }
}'
```

## 测试插件

- 缺少 Authorization header

```shell
$ curl -i http://127.0.0.1:9080/hello
HTTP/1.1 401 Unauthorized
...
{"message":"Missing authorization in request"}
```

- 用户名不存在：

```shell
$ curl -i -ubar:bar http://127.0.0.1:9080/hello
HTTP/1.1 401 Unauthorized
...
{"message":"Invalid user key in authorization"}
```

- 密码错误：

```shell
$ curl -i -ufoo:foo http://127.0.0.1:9080/hello
HTTP/1.1 401 Unauthorized
...
{"message":"Password is error"}
...
```

- 成功请求：

```shell
$ curl -i -ufoo:bar http://127.0.0.1:9080/hello
HTTP/1.1 200 OK
...
hello, foo!
...
```

## 禁用插件

当你想去掉 `basic-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://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "methods": ["GET"],
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:8080": 1
        }
    }
}'
```
