将 BIN 文件解码为 JSON 文件、协议缓冲区、Visual Studio 代码

Question

I have to decode BIN file downloaded from a company server to.txt or JSON File format using protocol buffer/compiler (which I have installed). I am using the following decode command in VS Code terminal for the purpose but do not able to deduce the error. I am an automotive systems engineer with no knowledge of coding language and have to decode the BIN file to complete my graduation thesis, so any help will be great full.

Windows Powershell error:

PS C:\Users\user\Desktop\MyPrograms> C:\protoc-3.14.0-win64\bin\protoc --decode=se.niradynamics.ncs.protobuf.output.RoadLayerTile roadlayertile.proto "< road_roughness_aggregation_23602633.bin >" output.txt
Could not make proto path relative: < road_roughness_aggregation_23602633.bin >: No such file or directory

Answer 1

It's just that it can't find the bin file, you have to search for it with the Windows file manager .

Answer 2

You should not have quotes around the pipe ( < and > ) operations, otherwise instead of redirecting stdin / stdout, you are looking for the literal file with > and < in the path, which isn't a thing that can exist. Take away the double quotes entirely.

To be honest though: using protoc here is very much doing this the hard way. If this was me, I'd run the.proto through either protoc or protogen to get a code model that represents the schema in my language of choice, and deserialize into that , then run that model through any JSON serializer.
