> 看了一下2.15版本的APISIX发现和代码也对上了，走了ext-plugin-post-resp.lua插件的重试逻辑 Retries don't happen every time, only if the java plugin runner has handled the exception, ref: https://github.com/apache/apisix/blob/master/apisix/plugins/ext-plugin/init.lua#L730-L742 ``` local ok, err = send(sock, constants.RPC_HTTP_RESP_CALL, builder:Output()) if not ok then return nil, "failed to send RPC_HTTP_RESP_CALL: " .. err end local ty, resp = receive(sock) if ty == nil then return nil, "failed to receive RPC_HTTP_RESP_CALL: " .. resp end if ty ~= constants.RPC_HTTP_RESP_CALL then return nil, "failed to receive RPC_HTTP_RESP_CALL: unexpected type " .. ty end ``` I have reproduced it again in [Debug mode](https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/how-it-works.md#debug) I still can't reproduce it. Here is my reproduction process: 1. upstream(an openresty server) ``` master_process on; worker_processes 2; error_log logs/error.log warn; pid logs/nginx.pid; worker_rlimit_nofile 20480; events { accept_mutex off; worker_connections 10620; } worker_shutdown_timeout 3; http { server { listen 1980; access_log off; location / { content_by_lua_block { ngx.status = 204 ngx.say("hello, world") } } } } ``` test ``` curl http://127.0.0.1:1980/get -i HTTP/1.1 204 No Content Server: openresty/1.21.4.1 Date: Thu, 25 Aug 2022 04:19:24 GMT Connection: keep-alive ``` 2. route ``` curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "uri":"/get", "plugins":{ "ext-plugin-post-resp":{ "conf":[ { "name":"TestResponseFilter", "value":"{\"rewrite_path\":\"token\",\"validate_url\":\"https://www.sso.foo.com/token/validate\",\"rejected_code\":\"403\"}"; } ] } }, "upstream":{ "nodes":{ "127.0.0.1:1980":1 }, "type":"roundrobin" } }' ``` config.yaml ``` apisix: admin_key: - name: admin key: edd1c9f034335f136f87ad84b625c8f1 # using fixed API token has security risk, please update it when you deploy to production environment role: admin ext-plugin: path_for_test: "/tmp/runner.sock" ``` 4. java plugin runner: https://github.com/tzssangglass/java-plugin-runner-demo-1 5. test proxy by APISIX and connect to java plugin runner ``` curl http://127.0.0.1:9080/get -i HTTP/1.1 204 No Content Connection: keep-alive Date: Thu, 25 Aug 2022 04:15:20 GMT Date: Thu, 25 Aug 2022 04:15:20 GMT Server: APISIX/2.15.0 ``` the logs of java plugin runner ``` 2022-08-25 12:15:14.714 INFO 2521381 --- [ main] c.e.d.DemoApplication : No active profile set, falling back to 1 default profile: "default" 2022-08-25 12:15:15.229 INFO 2521381 --- [ main] c.e.d.DemoApplication : Started DemoApplication in 0.898 seconds (JVM running for 1.716) 2022-08-25 12:15:15.362 WARN 2521381 --- [ main] o.a.a.p.r.s.ApplicationRunner : java runner is listening on the socket file: /tmp/runner.sock 2022-08-25 12:15:20.278 WARN 2521381 --- [ntLoopGroup-2-2] c.e.d.TestResponseFilter : status : 204 ``` -- This is an automated message from the Apache Git Service.
