golang_server_python_client_protobuf

Simple Golang HTTP Server and Python HTTP Client. Both communicates using Protocol Buffer

Main outcome of this repo is to use the Protocol Buffers (Protobuf) in the REST API.

The HTTP Server is written in Golang and the HTTP Client is our Python. This two communicates using Protobuf.(Atleast the Server will always respond with the Protobuf message serialized to bytes)

The Client which receivers the bytes then Deserialize to the Protobuf message.

Details of the Files and Folders:

• http_client - contains the Python HTTP client file and also the compiled proto file output in the pb_files folders

• http_server - contains the Golang HTTP server file

• proto_files - has the proto files

• src - directory for the Golang PB file compiled by protoc

Prerequisites:

• protoc installed

• protoc-go-gen Plugin installed

• protobuf - for both the Python and Golang

PATHS:

• Append the Project's root directory path to the GOPATH and also PYTHONPATH if required

Usage:

• To start the HTTP server, navigate to the http_server folder and execute

    go run main.go
  

• Now, the HTTP server is up and running in the localhost:8090. This URL has been provided to the Python Client file. To run the client, navigate to the http_client folder and execute

    python client.py
           or
    python3 client.py
