grpc client code:

)
func main() {
conn, err := grpc.Dial(address, grpc.WithInsecure())
if err != nil {
log.Fatal("did not connect: ", err)
}
defer conn.Close()
c := pb.NewGreeterClient(conn)
r, err := c.SayHello(context.Background(), &pb.HelloRequest{Name: "xiaoming"})
if err != nil {
log.Fatal("could not greet: %v", err)
}
fmt.Println(r)

> I think you should read the error message of your gRPC client carefully.
yes. This is a very basic question. You just need to check the error message more carefully

The following is related to APISIX processing of the gRPC protocol
1. gRPC Web Client -> APISIX -> gRPC server
use `grpc-web` plugin.
2. HTTP(s) -> APISIX -> gRPC server
use `grpc-transcode` plugin
3. gRPC server -> APISIX -> gRPC server
use
```
"upstream": {
"scheme": "grpc",
```
Depending on your needs, select the plugin or specify the upstream schema.

@tao12345666333 i used grpc example and made a simple modification. In addition, apisix configuration also refers to the official website. Note that there is no GRPC plugin.
