protocol-buffers

问题 I am using the Dialogflow API for Nodejs. This API is apparently implemented by Google via protocol buffers, though it presents a simple JavaScript/JSON based interface that I have used successfully for simple queries. In order to request Dialogflow send me response data for a particular platform, I apparently need to encode a simple JSON object into protobuf format. The linked source gives an example that makes use of a "structjson util" that can presumably be used to do the necessary

问题 I want to compile my .proto file into stubs, but when entering the command: `protoc -I=. ./protos/dummy.proto --js_out=import_style=commonjs,binary:./server --grpc_out=./server --plugin=protoc-gen-grpc=which grpc_tools_node_protoc_plugin I got the following error : --grpc_out: protoc-gen-grpc: %1 is not a valid Win32 application. Thigs I have installed : Windows 10 npm install -g grpc-tools npm install google-protobuf protoc NOTE: I noticed there are a few similar questions already, but I

问题 I can't seem to find a comparison method in the API. So I have these two messages, and they have a lot of different values that sometimes drill down to more values (for example, I have a Message that has a string, an int, and a custom_snapshot, where custom_snapshot is comprised of an int, a string, and so on). I want to see if these two messages are the same. I don't want to compare each value one by one, since that will take a while, so I was wondering if there was a quick way to do this in

问题 I am trying to use Protocol Buffers - Google's data interchange format referring https://github.com/google/protobuf/tree/master/js I tried to follow documentation i am able to get the setup of Protocol Compiler and able to do protoc --js_out=library=myproto_libs,binary:. messages.proto but when i do npm install google-protobuf i am getting npm ERR! 404 Registry returned 404 for GET on https://registry.npmjs.org/google- npm ERR! 404 npm ERR! 404 'google-protobuf' is not in the npm registry.

问题 I'm trying to get a simple Python script up to convert protobuf files into json files (required format for what I'm doing at work). I've seen some recommendations to upgrade to Python 3.6.1 (I'm at 3.6.0), up/downgrade google.protobuf. Neither solution helped. def convert_to_json(directory: str): os.chdir(jsonPath) for (root, dirs, files) in os.walk(os.getcwd()): for file_ in files: if os.path.dirname(file_) != root and file_.endswith(".pb"): json_file: str = MessageToJson(file_) file_name =

问题 my application sends data through protobuf from a server to a client. When I am deserializing the sent payload on the client side eclipse throws a expection of the follogwing type: Exception in thread "main" com.google.protobuf.InvalidProtocolBufferException: Protocol message tag had invalid wire type. The expection happens when I call "parseFrom()". I know that in most cases the error lies in a protobuf file with the wrong syntax. Therefore I hope that it is enough to post the protobuf
