# 功能说明
|
||||
`basic-auth`插件实现了基于 HTTP Basic Auth 标准进行认证鉴权的功能
|
||||
|
||||
# 配置字段
|
||||
|
||||
| 名称 | 数据类型 | 填写要求 | 默认值 | 描述 |
|
||||
| ----------- | --------------- | -------- | ------ | ---------------------------------------------------- |
|
||||
| `consumers` | array of object | 必填 | - | 配置服务的调用者,用于对请求进行认证 |
|
||||
| `_rules_` | array of object | 选填 | - | 配置特定路由或域名的访问权限列表,用于对请求进行鉴权 |
|
||||
|
||||
`consumers`中每一项的配置字段说明如下:
|
||||
|
||||
| 名称 | 数据类型 | 填写要求 | 默认值 | 描述 |
|
||||
| ------------ | -------- | -------- | ------ | ------------------------ |
|
||||
| `credential` | string | 必填 | - | 配置该consumer的访问凭证 |
|
||||
| `name` | string | 必填 | - | 配置该consumer的名称 |
|
||||
|
||||
`_rules_` 中每一项的配置字段说明如下:
|
||||
|
||||
| 名称 | 数据类型 | 填写要求 | 默认值 | 描述 |
|
||||
| ---------------- | --------------- | ------------------------------------------------- | ------ | -------------------------------------------------- |
|
||||
| `_match_route_` | array of string | 选填,`_match_route_`,`_match_domain_`中选填一项 | - | 配置要匹配的路由名称 |
|
||||
| `_match_domain_` | array of string | 选填,`_match_route_`,`_match_domain_`中选填一项 | - | 配置要匹配的域名 |
|
||||
| `allow` | array of string | 必填 | - | 对于符合匹配条件的请求,配置允许访问的consumer名称 |
|
||||
|
||||
**注意:**
|
||||
- 若不配置`_rules_`字段,则默认对当前网关实例的所有路由开启认证;
|
||||
- 对于通过认证鉴权的请求,请求的header会被添加一个`X-Mse-Consumer`字段,用以标识调用者的名称。
|
||||
|
||||
# 配置示例
|
||||
|
||||
## 对特定路由或域名开启认证和鉴权
|
||||
|
||||
以下配置将对网关特定路由或域名开启 Basic Auth 认证和鉴权,注意凭证信息中的用户名和密码之间使用":"分隔,`credential`字段不能重复
|
||||
|
||||
```yaml
|
||||
# 使用 _rules_ 字段进行细粒度规则配置
|
||||
consumers:
|
||||
- credential: 'admin:123456'
|
||||
name: consumer1
|
||||
- credential: 'guest:abc'
|
||||
name: consumer2
|
||||
_rules_:
|
||||
# 规则一:按路由名称匹配生效
|
||||
- _match_route_:
|
||||
- route-a
|
||||
- route-b
|
||||
allow:
|
||||
- consumer1
|
||||
# 规则二:按域名匹配生效
|
||||
- _match_domain_:
|
||||
- "*.example.com"
|
||||
- test.com
|
||||
allow:
|
||||
- consumer2
|
||||
```
|
||||
|
||||
此例 `_match_route_` 中指定的 `route-a` 和 `route-b` 即在创建网关路由时填写的路由名称,当匹配到这两个路由时,将允许`name`为`consumer1`的调用者访问,其他调用者不允许访问;
|
||||
|
||||
此例 `_match_domain_` 中指定的 `*.example.com` 和 `test.com` 用于匹配请求的域名,当发现域名匹配时,将允许`name`为`consumer2`的调用者访问,其他调用者不允许访问。
|
||||
|
||||
### 根据该配置,下列请求可以允许访问:
|
||||
|
||||
**请求指定用户名密码**
|
||||
|
||||
```bash
|
||||
# 假设以下请求将会匹配到route-a路由
|
||||
# 使用 curl 的 -u 参数指定
|
||||
curl -u admin:123456 http://xxx.hello.com/test
|
||||
# 或者直接指定 Authorization 请求头,用户名密码使用 base64 编码
|
||||
curl -H 'Authorization: Basic YWRtaW46MTIzNDU2' http://xxx.hello.com/test
|
||||
```
|
||||
|
||||
认证鉴权通过后,请求的header中会被添加一个`X-Mse-Consumer`字段,在此例中其值为`consumer1`,用以标识调用方的名称
|
||||
|
||||
### 下列请求将拒绝访问:
|
||||
|
||||
**请求未提供用户名密码,返回401**
|
||||
```bash
|
||||
curl http://xxx.hello.com/test
|
||||
```
|
||||
**请求提供的用户名密码错误,返回401**
|
||||
```bash
|
||||
curl -u admin:abc http://xxx.hello.com/test
|
||||
```
|
||||
**根据请求的用户名和密码匹配到的调用者无访问权限,返回403**
|
||||
```bash
|
||||
# consumer2不在route-a的allow列表里
|
||||
curl -u guest:abc http://xxx.hello.com/test
|
||||
```
|
||||
|
||||
## 网关实例级别开启
|
||||
|
||||
以下配置未指定`_rules_`字段,因此将对网关实例级别开启 Basic Auth 认证
|
||||
|
||||
```yaml
|
||||
consumers:
|
||||
- credential: 'admin:123456'
|
||||
name: consumer1
|
||||
- credential: 'guest:abc'
|
||||
name: consumer2
|
||||
```
|
||||
|
||||
# 相关错误码
|
||||
|
||||
| HTTP 状态码 | 出错信息 | 原因说明 |
|
||||
| ----------- | ------------------------------------------------------------------------------ | ---------------------- |
|
||||
| 401 | Request denied by Basic Auth check. No Basic Authentication information found. | 请求未提供凭证 |
|
||||
| 401 | Request denied by Basic Auth check. Invalid username and/or password | 请求凭证无效 |
|
||||
| 403 | Request denied by Basic Auth check. Unauthorized consumer | 请求的调用方无访问权限 |
