Building Micro-services with GO | Part1

  • Developing Microservices in GO.
  • Creating Http Web Server in GO.
  • Read the request body in GO.
  • Write the response back in GO.
  • Handling Error in Go.
  • Accessing the handler from different package in Go.
  • It registers the handler function for the given pattern in the DefaultServeMux.
  • It creates an HttpHandler from it and adds it to the DefaultServeMux.
  • It is responsible for redirecting the paths. It contains the logic to be able to determine, which particular handler is to be called based upon the path.
  • Basically, it determines, which function would get executed whenever a request lands, depending upon where it has been mapped.
  • “http” package does have a DefaultServeMux. If we don’t set anything else up, this is the one, which is used by HandleFunc() function.
  • It allows you to have multiple handlers.
  • First parameter indicates the Port, where this server shall be hosted.
  • Second parameter indicates the Handler as simple as that. If we don’t specify anything
  • In the left-terminal, we have started our server.
  • In the right-terminal, we have verified by hitting to the hosted API.
