问题 I'm considering using dart-protobuf instead of JSON in one of my projects. The problem is that the library does not provide any example of how to use it, and the tests don't really help either. I'm also a bit confused on how the parsing of .proto files would work. So I'm looking for a simple example of how to use this library in dart. 回答1: I'm not too familiar with dart-protobuf, but it looks like you have to use the protobuf compiler and the dart-protoc-plugin project to generate your Dart

问题 I have a simple setup of one client and one server. The client wants to execute a method in the server using ZeroMQ for communications. I am going to use the REQ and REP sockets because they are suitable for this use case. Nevertheless I have a doubt about the protobuf definitions. I think these two options can be used for achieving the goal: message ControlService{ string control = 1; int32 serverId = 2; bool block = 3; double temperature = 4; } Where "control" contains the name of the

问题 I currently manage a few separate Maven projects in which I use Protobufs as a serialization format and over the wire. I am using David Trott's maven-protoc plugin to generate the code at compile time. All is good and well until I want those project to communicate between one another — or rather, use each other's protobufs. The protobuf language has an "import" directive which does what I want but I'm faced with the challenge of having project A exporting a ".proto" file (or possibly some

问题 message HealthOccurrenceCount { required int64 HealthID=1; required int32 OccCount=2; optional bytes wci=3; } I would like to add data based on HealthID ; If HealthID is already entered then instead of adding a new entry, the program should instead just increment the existing entry's OccCount . HealthOccurrenceCount objHelthOccCount; if(objHelthOccCount.healthid() == healthID) // Is this right or do I need to iterate all the nodes? { occCount++; objHelthOccCount.set_occcount(occCount); } else

问题 I have a program that serializes data with Protobuf in Java, by writing binary data in a byte[] Array and then saving it in ".txt" file. I am receiving that data on the C++ side in a stringstream. Now I want to parse that binary data with C++, but the Protobuf-Parsing-Method "parseFromString()" doesn't work! The fields from my Test Message are not set. I wrote a little test for that and I can show you some code: Java Serialization byte[] s = test.build().toByteArray(); //This is serialized to
