Http Server

Presentation

• First Request Handler approach

Pitfalls

• Socket Server

  • Reading the whole response is not possible with readLine() or lines() (Stream)
    • Problem: The request stays open until the response is coming from the server
    • Solution: extract the Content-Length and read only char by char!
  • Postman sends 2 requests towards localhost. The first one acts like a ping and is cancelled shortly after
    • Problem: The server crashed because of the wrong handling of the client request
    • Solution: Proper Exception handling at every level

• Reflections

  • First time using it so I had to read a bit into it
  • One important feature was automatically knowing which parameter in the method belongs to which path variable in the url
  • So I just use the parameter name and compare it to the path (ex. "/api/{username}"). Problem: Method Parameter names are generalized by the compiler by default (String username => String arg1).
  • Solution: Add Compiler Argument -parameters => does not change the parameter name (since Java 8).
