# 功能说明
`request-block`插件实现了基于 URL、请求头等特征屏蔽 HTTP 请求,可以用于防护部分站点资源不对外部暴露
# 配置字段
| 名称 | 数据类型 | 填写要求 | 默认值 | 描述 |
| -------- | -------- | -------- | -------- | -------- |
| block_urls | array of string | 选填,`block_urls`,`block_headers`,`block_bodys` 中至少必填一项 | - | 配置用于匹配需要屏蔽 URL 的字符串 |
| block_headers | array of string | 选填,`block_urls`,`block_headers`,`block_bodys` 中至少必填一项 | - | 配置用于匹配需要屏蔽请求 Header 的字符串 |
| block_bodys | array of string | 选填,`block_urls`,`block_headers`,`block_bodys` 中至少必填一项 | - | 配置用于匹配需要屏蔽请求 Body 的字符串 |
| blocked_code | number | 选填 | 403 | 配置请求被屏蔽时返回的 HTTP 状态码 |
| blocked_message | string | 选填 | - | 配置请求被屏蔽时返回的 HTTP 应答 Body |
| case_sensitive | bool | 选填 | true | 配置匹配时是否区分大小写,默认区分 |
# 配置示例
## 屏蔽请求 url 路径
```yaml
block_urls:
- swagger.html
- foo=bar
case_sensitive: false
```
根据该配置,下列请求将被禁止访问:
```bash
curl http://example.com?foo=Bar
curl http://exmaple.com/Swagger.html
```
## 屏蔽请求 header
```yaml
block_headers:
- example-key
- example-value
```
根据该配置,下列请求将被禁止访问:
```bash
curl http://example.com -H 'example-key: 123'
curl http://exmaple.com -H 'my-header: example-value'
```
## 屏蔽请求 body
```yaml
block_bodys:
- "hello world"
case_sensitive: false
```
根据该配置,下列请求将被禁止访问:
```bash
curl http://example.com -d 'Hello World'
curl http://exmaple.com -d 'hello world'
```
## 对特定路由或域名开启
```yaml
# 使用 _rules_ 字段进行细粒度规则配置
_rules_:
# 规则一:按路由名称匹配生效
- _match_route_:
- route-a
- route-b
block_bodys:
- "hello world"
# 规则二:按域名匹配生效
- _match_domain_:
- "*.example.com"
- test.com
block_urls:
- "swagger.html"
block_bodys:
- "hello world"
```
此例 `_match_route_` 中指定的 `route-a``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,将使用此段配置;
此例 `_match_domain_` 中指定的 `*.example.com``test.com` 用于匹配请求的域名,当发现域名匹配时,将使用此段配置;
配置的匹配生效顺序,将按照 `_rules_` 下规则的排列顺序,匹配第一个规则后生效对应配置,后续规则将被忽略。
# 请求 Body 大小限制
当配置了 `block_bodys` 时,仅支持小于 32 MB 的请求 Body 进行匹配。若请求 Body 大于此限制,并且不存在匹配到的 `block_urls``block_headers` 项时,不会对该请求执行屏蔽操作
当配置了 `block_bodys` 时,若请求 Body 超过全局配置 DownstreamConnectionBufferLimits将返回 `413 Payload Too Large`
