[GitHub] [apisix] jagerzhang opened a new issue #6368: request help: can Admin API supports route hit detection?
jagerzhang opened a new issue #6368:
URL: https://github.com/apache/apisix/issues/6368
### Issue description
Hi，我想请教下APISIX有没有可能提供一个探测路由配置是否命中的接口？比如想 admin-api POST 一个新的路由配置Body，api告诉这个配置是否命中存量路由。
```
POST /apisix/admin/routes/probe
{
"uris": [
"/demo"
],
"methods": [
"GET",
"POST",
"HEAD"
],
"hosts": [
"demo.domain1.com",
"demo.domain2.com",
]
}
```
比如命中可以返回命中的路由ID等信息：
```
{
"msg": "hit",
"route_id": "xxxx"
"code": 200
}
```
### 可能这个需求有点偏，不过还是想请教下。下面是我的场景描述：
=============================================
### 背景
我们想基于APISIX包装一个HTTP 7层业务网关服务，每个业务在门户中设置租户隔离，业务只能看到和自己相关的服务、上游、路由以及消费者等，业务之间可以通过服务自带的消费者去申请调用权限，其他则不在有数据上的交叉。
### 问题
在这个背景下，希望业务方在添加路由的时候，能够主动探测路由冲突情况，判断是否会覆盖掉现有路由，导致故障。但是APISIX好像并没有这种检测机制，可以随便添加相同或相近的路由配置。
### 解决
方案1：我们在设计网关服务的时候增加限制逻辑，会持久化记录路由配置信息，比如请求方法、域名、url等，然后在业务添加路由的时候判断是否冲突，再做后续的限制或提示逻辑。
方案2：和方案1类似增加限制逻辑，但是判断是否冲突**是通过APISIX的接口**来查询是否命中已有路由，整体更加简单，数据都在APISIX，不额外增加其他存储。
### Environment
- apisix version (cmd: `apisix version`): 2.12.0
- OS (cmd: `uname -a`): docker-centos

How does this interface distinguish `path` from the HTTP request? As we need to use a special path to reach the interface.

Put in the request body? Seems like a bit of a hassle too. It seems like a good option to add a parameter inside debug mode to control this functionality.

如果能做到，这个方案应该更简洁一些，如果不好实现的话，罗总提到的特殊实例+debug这个方案应该也可以满足。
我们这边讨论了下，考虑先在管理层自己做一下限制，有需要的同学可以参考：

Tying the domain name to the business system and dividing the detection area works, I have done a similar design.

can we add a control API and call
```lua
local router = require("apisix.router")
router.router_http.match(api_ctx)
```
in control API function.

Look like we can add a match_only option to the debug.yaml?
When this option is on, we just return matched router so we can deploy a special APISIX instance to check if there is conflict.
