Mt client side uses sync API, as shown below.
class GreeterClient {
public:
GreeterClient(std::shared_ptr<Channel> channel)
: stub_(Greeter::NewStub(channel)) {}
// Assambles the client's payload, sends it and presents the response back
// from the server.
std::string SayHello(const std::string& user) {
// Data we are sending to the server.
HelloMessage request;
request.set_message(user);
// Container for the data we expect from the server.
HelloMessage reply;
// Context for the client. It could be used to convey extra information
to
// the server and/or tweak certain RPC behaviors.
ClientContext context;
std::shared_ptr<ClientReaderWriter<HelloMessage, HelloMessage> >
stream(stub_->SayHello(&context));
// The actual RPC.
stream->Write(request);
stream->Read(&reply);
return reply.message();
}
private:
std::unique_ptr<Greeter::Stub> stub_;
};
int main(int argc, char** argv) {
// Instantiate the client. It requires a channel, out of which the actual
RPCs
// are created. This channel models a connection to an endpoint (in this
case,
// localhost at port 50051). We indicate that the channel isn't
authenticated
// (use of InsecureChannelCredentials()).
GreeterClient greeter(grpc::CreateChannel(
"localhost:50051", grpc::InsecureChannelCredentials()));
std::string user("world");
std::string reply = greeter.SayHello(user);
std::cout << "Greeter received: " << reply << std::endl;
return 0;
}
