You can set the GRPC_TRACE environment variable to all to have grpc dump a whole bunch of data about what the connection is doing: export GRPC_TRACE=all edit from comment: apparently you also need to set: export GRPC_VERBOSITY=DEBUG
the missing plugin has been implemented at https://github.com/grpc/grpc-go. command below should fix it go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
The command line you are showing does not enable the grpc plugin. You need to specify an _out argument for the grpc plugin, which enables the plugin and specifies where it should output files. Since the plugin is likely not in your PATH, you also need to tell protoc how to find the plugin with … Read more
It seems like you have some verion conflict Expected directory: node-v57-linux-x64-glibc Found: [node-v59-linux-x64-glibc] Have you tried running npm rebuild in your app folder?
Include additional error details in the response Metadata. However, still make sure to provide a useful status code and message. In this case, you can add RegisterUserResponse to the Metadata. In gRPC Java, that would look like: Metadata.Key<RegisterUserResponse> REGISTER_USER_RESPONSE_KEY = ProtoUtils.keyForProto(RegisterUserResponse.getDefaultInstance()); … Metadata metadata = new Metadata(); metadata.put(REGISTER_USER_RESPONSE_KEY, registerUserResponse); responseObserver.onError( Status.INVALID_ARGUMENT.withDescription(“Email or password malformed”) .asRuntimeException(metadata)); … Read more
When done correctly, REST improves long-term evolvability and scalability at the cost of performance and added complexity. REST is ideal for services that must be developed and maintained independently, like the Web itself. Client and server can be loosely coupled and change without breaking each other. RPC services can be simpler and perform better, at … Read more
If it’s still relevant for you, I’ve created gRPC spring-boot-starter here. grpc-spring-boot-starter auto-configures and runs the embedded gRPC server with @GRpcService-enabled beans. The simplest example : @GRpcService(grpcServiceOuterClass = GreeterGrpc.class) public static class GreeterService implements GreeterGrpc.Greeter { @Override public void sayHello(GreeterOuterClass.HelloRequest request, StreamObserver<GreeterOuterClass.HelloReply> responseObserver) { // omitted } } There is also an example of how … Read more
async req / res communication (inproc or remote) between nodes Both libraries allow for synchronous or asynchronous communication depending on how to implement the communication. See this page for gRPC: http://www.grpc.io/docs/guides/concepts.html. Basically gRPC allow for typical HTTP synchronous request/response or a ‘websocket-like’ bidirectional streaming. For 0mq you can setup a simple REQ-REP connection which is … Read more
First, upgrade pip pip3 install –upgrade pip Then, update the setup tools: python3 -m pip install –upgrade setuptools At last, install grpcio using : pip3 install –no-cache-dir –force-reinstall -Iv grpcio==<version_number>
Tannisha Hill indicated that the following package had to be added: sudo apt install protobuf-compiler In my case, I also had to add this one: sudo apt install golang-goprotobuf-dev
