Hi,
I' ve got a problem to create dynamic message from JSON.
I want to use that message to send it through the MannagedChannel using the
command 'newCall()'
Here is my progress:
File file = new File("/path/to/api_descriptor.pb");
byte[] payload = ByteStreams.toByteArray(new FileInputStream(file));
ExtensionRegistry registry = ExtensionRegistry.newInstance();
registry.add(AnnotationsProto.http);
FileDescriptorSet set = FileDescriptorSet.parseFrom(payload, registry);
//I got only 1 file in the set
FileDescriptorProto fileDescriptor = set.getFile(0);
//Here I get message type which is used from my grpc service
(RegisterCustomerRequest). I am sure it is first one.
DescriptorProto requestDescriptor = descriptor.getMessageType(0);
DynamicMessage.Builder messageBuilder =
DynamicMessage.newBuilder(requestDescriptor);
JsonFormat.parser().merge("{\"customerInfo\":{\"firstName\":\"John\",\"lastName\":\"Doe\"}}",
messageBuilder);
But parsing the message throw an error:
com.google.protobuf.InvalidProtocolBufferException: Cannot find field:
customerInfo in message google.protobuf.DescriptorProto
Can some one guide me what I am doing wrong and how can I parse this JSON
message ?
