How to stream result from grpc-server and how to return result from goroutines grpc server-stream to pass result to api

it should still fix some issue If I understood you correctly -> this is server grpc endpoint and your problem is how to send models.DronePosition back to the client. If so, then you have bidirectional streaming and you can solve this problem as:
code :
dronePosition := models.DronePosition{
                Name:          uavID.Aircraft,
                ItemParameter: itemParameter,
            }
position <- dronePosition
err = stream.Send(&dronePosition)

will be helpful for those in need You havent received any callback method at function definition so i added a callback parameter, this callback method will be called with required parameters. You will receive data at your main method
code :
 getUser(ctx, callback) {
    models.users.findAll({
            where: { userId: ctx.req.userId }
        }).then(function(users){
            // return a list of users
           for (var i = 0, len = users.length; i < len; i++) {
             result.push({'userId': users[i].userId, 'userName': users[i].userName);
           }

           callback(null,{ 'users': result});
        }.bind(this));
     }
   }
function main() {
  var client = new guser_proto.User('localhost:50051',
                                       grpc.credentials.createInsecure());

    client.getUser({userId: '8888'}, function(err, response) {
      console.log(response); // it will print here 
    });
} 

Can we reliably log the result of every gRPC call to our grpc-java server?

hope this fix your issue You want ServerCall.Listener.onComplete() and ServerCall.Listener.onCancel(). onComplete() is called after ServerCall.close() is processed successfully. onCancel() is used for any communication error or cancellation. Note that it is possible to receive onCancel() after the application calls ServerCall.close().

gRPC Unary Stream from Python server -> C# Client: "Stream removed"

To fix this issue Turns out this was a problem with the google-cloud-endpoint/NGINX container being terminated before the gRPC server container in the same pod had a chance to close it's connections gracefully.
If anyone is remotely interested in knowing more, there's a conversation I had with myself over here: https://groups.google.com/forum/#!topic/google-cloud-endpoints/FyfdvD6xS1Q

I wish this helpful for you i programming an Application for my study. , Solved it by Replacing
code :
channel = GrpcChannel.ForAddress(connectionString);
        if (connectionString.Contains("http://"))
        {
            AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);
            string newConString = connectionString.Replace("http://", "");
            return new Channel(newConString, ChannelCredentials.Insecure);
        }
        else
        {
            string newConString = connectionString.Replace("https://", "");
            return new Channel(newConString, new SslCredentials());
        }
