Simple gRPC calculator implementation with SSL, login and headers interceptors.
gRPC Unary:
rpc Sum(SumRequest) returns (SumResponse);- Error Handling:
rpc Sqrt(SqrtRequest) returns (SqrtResponse);
gRPC Server Streaming:
rpc Primes(PrimesRequest) returns (stream PrimesResponse)
gRPC Client Streaming:
rpc Average(stream AverageRequest) returns (AverageResponse)
gRPC Bidirectional:
rpc Max(stream MaxRequest) returns (stream MaxResponse)
- Install protobuf go plugins
$ go install google.golang.org/protobuf/cmd/[email protected]
$ go install google.golang.org/grpc/cmd/[email protected]
$ export PATH="$PATH:$(go env GOPATH)/bin"- Compile proto files
$ cd proto
$ protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative *.proto- Uncomment client/main.go with the function to test
//DoSum(c, &pb.SumRequest{FirstValue: 1, SecondValue: 1})
//DoSumDeadline(c, &pb.SumRequest{FirstValue: 1, SecondValue: 1}, 5*time.Second) // no error
//DoSumDeadline(c, &pb.SumRequest{FirstValue: 1, SecondValue: 1}, 1*time.Second) // timeout error
//DoPrimes(c, 400)
//DoAverage(c, []float64{1, 2, 3, 4})
//DoMax(c, []int32{1, 5, 3, 6, 2, 20})
//DoSqrt(c, -9)
- Generate certs
$ cd ssl
$ bash generate-certs.sh- Compile server and client
$ cd ..
$ go build -o server/server server/*.go
$ go build -o client/client client/*.go- Run server and client
# Run server
$ ./server/server
# Run client on another terminal
$ ./client/client
