C++, How to communicate with Python?

Communicate with the cpp program while the Python server is running.

using gRPC protocols

Installation

1. CPP

   > git clone https://github.com/Microsoft/vcpkg.git vcpkg
   > cd .\vcpkg
   > powershell.exe .\bootstrap-vcpkg.bat
   
   # c++ 17
   > git checkout be1e1b72e7c5a9a07268c99c4a50d2ace0e2b469 -- ports/abseil
   > cd .\triplets
   # in x64-windows-static.cmake, x64-windows.cmake
   # append belows
   > set(VCPKG_CXX_FLAGS "/std:c++17")
   > set(VCPKG_C_FLAGS "")
   > cd ..
   
   > .\vcpkg install abseil:x64-windows
   > .\vcpkg install grpc:x64-windows
   > .\vcpkg integrate install

2. Python

   > python -m venv my_env
   > my_env\Scripts\activate
   (my_env) > pip install grpcio
   (my_env) > pip install grpcio-tools

Compile, Build

1. Client

   > %CD%\..\vcpkg\installed\x64-windows\tools\protobuf\protoc.exe --proto_path=%CD% --cpp_out=%CD% --grpc_out=%CD% --plugin=protoc-gen-grpc=%CD%\..\vcpkg\installed\x64-windows\tools\grpc\grpc_cpp_plugin.exe %CD%\service.proto

2. Server

   (my_env) > python -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. service.proto
