Hy all
We have two clients (c++ and c#). We're generating a c++ and a c# object
out of our proto2 proto-definition:
syntax = "proto2";
option csharp_namespace = "xxx.yyy";
message Data {
required int32 id = 1;
optional Data2 data2 = 2;
}
message Data2 {
optional int32 id = 1;}
}
...
We need to use proto2 (this is a requirement of the framework we use in our
c++ application). For generating the c# class, we use the following
protoc-version:
- protoc-3.0.0-alpha-3-win32>
...because this is the latest version, which works with proto2 definitions.
*****************
We would also like to expose functionality from our c# application to other
external clients, so we're discussing this two scenarios:
- Variant A: Using GPRC
- Variant B: Using a REST Service
Variant A:
We added the service definition to our proto-file:
syntax = "proto2";
option csharp_namespace = "xxx.yyy";
service TestService {
rpc SendData (Data) returns (Data) {}
}
message Data {
required int32 id = 1;
optional Data2 data2 = 2;
}
message Data2 {
optional int32 id = 1;}
}
Then we've tried to create the server/client stub according to:
https://grpc.io/docs/quickstart/csharp.html
...but this does not work with our proto2 defined proto file:
C# code generation only supports proto3 syntax
-> So this will not work with our proto2-definition right?
Variant B:
How can we expose our auto-generated ProtoBuf object to REST without
writing a new Object and doing a mapping all the time?
Thanks for your help!
Kind regards,
Peter
