Hi,
Any one tested AF_UNIX socket file descriptor on gRPC C++? I have issue
connecting the client to server. and also I am not sure whether server
started with file descriptor or not. appreciated if any one give some
points in that front.
I changed hello world example to following:
server.cpp:
int socketFd = socket( AF_UNIX, SOCK_STREAM , 0);
struct sockaddr_un server_address;
server_address.sun_family = AF_UNIX;
strcpy(server_address.sun_path, "server_socket");
int server_len = sizeof(server_address);
bind(socketFd, (struct sockaddr *)&server_address, server_len);
std::string server_address2("127.0.0.1:50051");
GreeterServiceImpl service;
ServerBuilder builder;
builder.AddListeningPort(server_address2, grpc::InsecureServerCredentials
());
builder.RegisterService(&service);
std::unique_ptr<Server> server(builder.BuildAndStart());
grpc::AddInsecureChannelFromFd(server.get(), socketFd);
server->Wait();
client.cpp
int socketFd = socket( AF_UNIX, SOCK_STREAM, 0);
struct sockaddr_un address;
address.sun_family = AF_UNIX;
strcpy(address.sun_path, "server_socket");
int len = sizeof(address);
int st = connect( socketFd, (struct sockaddr *)&address, sizeof(address)
);
std::cout << "st " << st << std::endl;
GreeterClient greeter(grpc::CreateInsecureChannelFromFd("localhost",
socketFd));
if I change the address family to AF_INET then client gets the response
from server.
