ProtoBufJsonConverter

ProtoBufJsonConverter

This project uses protobuf-net to:

• Convert a protobuf message to a JSON string using the proto definition file.
• Convert a protobuf message to an object using the proto definition file.
• Convert a JSON string or an object to a protobuf message using the proto definition file.

Usage

Proto Definition

syntax = "proto3";

// Package name
package greet;

// The greeting service definition.
service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply);
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings
message HelloReply {
  string message = 1;
}

:one: Convert ProtoBuf byte[] to a JSON string

Code

var protoDefinition = "...". // See above

var bytes = Convert.FromBase64String("CgRzdGVm");

var request = new ConvertToJsonRequest(protoDefinition, "greet.HelloRequest", bytes);

var converter = new Converter();

var json = converter.Convert(request);

JSON

{"name":"stef"}

:one: Convert ProtoBuf byte[] to an object

Code

var protoDefinition = "...". // See above

var bytes = Convert.FromBase64String("CgRzdGVm");

var request = new ConvertToObjectRequest(protoDefinition, "greet.HelloRequest", bytes);

var converter = new Converter();

var @object = converter.Convert(request);

:three: Convert JSON string to a ProtoBuf byte[]

Code

var protoDefinition = "...". // See above

var json = @"{""name"":""stef""}";

var request = new ConvertToProtoBufRequest(protoDefinition, "greet.HelloRequest", json);

var converter = new Converter();

var protobuf = converter.Convert(request);

:four: Convert any object to a ProtoBuf byte[]

Code

var protoDefinition = "...". // See above

var obj = new
{
    name = "stef"
};

var request = new ConvertToProtoBufRequest(protoDefinition, "greet.HelloRequest", obj);

var converter = new Converter();

var protobuf = converter.Convert(request);

:five: Convert any object to a ProtoBuf byte[] including the Grpc Header

Code

var protoDefinition = "...". // See above

var obj = new
{
    name = "stef"
};

var request = new ConvertToProtoBufRequest(protoDefinition, "greet.HelloRequest", obj)
    .WithGrpcHeader();

var converter = new Converter();

var protobufWithGrpcHeader = converter.Convert(request);
