> If you want to use the grpc client to access APISIX, you need to enable the [grpc-transcode](https://github.com/apache/apisix/blob/master/docs/en/latest/plugins/grpc-transcode.md) plugin. > > `"scheme": "grpc"` in upstream configures the protocol for accessing upstream to be `grpc`. my call chain like this: 1.[RequestFilter return] --?--> GrpcClient (report error) GrpcClient --grpc--> Apisix --?--> Go-plugin-runner(ext-plugin-post-req) 2.[RequestFilter continue] --grpc--> GrpcServer --grpc--> Apisix --grpc--> GrpcClient(ok) in Go-plugin-runner, func RequestFilter like this: ``` func (p *Say) RequestFilter(conf interface{}, w http.ResponseWriter, r pkgHTTP.Request) { w.Header().Set("Content-Type", r.Header().Get("Content-Type")) num := rand.Int() if num%2 == 1 { w.WriteHeader(http.StatusOK) w.Header().Set("mykey", "test") w.Header().Set("Grpc-Status", "0") w.Header().Set("Grpc-Message", "ok") w.Header().Set("Grpc-Status-Details-Bin", "") return // here retrun to GrpcClient, is above chain 1, client report "server closed the stream without sending trailers" } return // here continue to GrpcServer then return to GrpcClient, is above chain 2, ok } ``` above not use grpc-transcode，grpc-transcode ot suitable for our scene。Please have a look and help， thanks a lot! -- This is an automated message from the Apache Git Service.
