help request: how to get route_id

[RangoStack]

Description

自定义插件怎么获取到请求的route_id呢？ ngx.ctx.api_ctx.route_id这种方式获取到的route_id与实际请求的route_id不一致的情况。

Environment

• APISIX version (run apisix version):
• Operating system (run uname -a):
• OpenResty / Nginx version (run openresty -V or nginx -V):
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info):
• APISIX Dashboard version, if relevant:
• Plugin runner version, for issues related to plugin runners:
• LuaRocks version, for installation issues (run luarocks --version):

@RangoStack Can you elaborate further? In which plugin are you trying to access the route id?

@RangoStack Please use English in the public channel, thx Back to your question, can you provide reproduction steps? How do check the route id is not the ngx.ctx.api_ctx.route_id?

[lingsamuel]

Please give a minimal reproducible example. I can't repro this on my side.

Here is my reproduce way with APISIX 3.2

1. edit request-id plugin

   
   function _M.header_filter(conf, ctx)
   if not conf.include_in_response then
       return
   end

• core.log.info("request-id got route_id: ", ngx.ctx.api_ctx.route_id) local headers = ngx.resp.get_headers() if not headers[conf.header_name] then core.response.set_header(conf.header_name, ctx["request-id-" .. conf.header_name]) end end

2. generate many routes

3. create a simple route with request-id plugin

   curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{
   "uri": "/*",
   "plugins": {
       "request-id": {
        }
   },
   "upstream": {
       "type": "roundrobin",
       "nodes": {
           "baidu.com:80": 1
       }
   }
   }'

4. query the route multiple times
