将protobuf枚举消息发送到grpc服务器

Question

Given a

message Foo {
enum State {
    STATE1 = 0;
    STATE2 = 1;
    STATE3 = 2;
}
}

and a grpc service definition of

rpc Method(stream Foo) returns (Empty) {}

What does the go grpc client code to send this to a grpc server look like? To clarify, suppose I have a streamClient.Send(). What would I pass to Send()? How do I construct the enum?

Answer 1

You define State but you do not have a State field in Foo.

Try this

syntax="proto3";
option go_package ="enumpb";
message Foo {
  enum State {
    STATE1 = 0;
    STATE2 = 1;
    STATE3 = 2;
  }
  State myState = 1;
}

And this in go

enumExample := enumpb.Foo{
    MyState: enumpb.Foo_STATE1,
}
fmt.Println("enumExample", enumExample)
