Step by Step solution about How to resolve the algorithm HTTPS/Authenticated step by step in the Haskell programming language

This is a simple Haskell program that sends a HTTP GET request with basic authentication to the "httpbin.org" server, the request is made to the "/basic-auth" endpoint with the username "someuser" and the password "somepassword". The program uses the Network.HTTP.Req library to send the request, and the Data.Aeson library to parse the JSON response.

The program first defines the main function, which is the entry point of the program. The main function uses the runReq function from the Network.HTTP.Req library to send the request. The runReq function takes a request configuration and a request body as arguments, and returns a Response object.

The req function is used to create a request configuration, and the GET constructor is used to specify that the request is a GET request. The https function is used to specify that the request is made over HTTPS, and the /: function is used to specify the path of the request. The NoReqBody constructor is used to specify that the request has no body, and the jsonResponse function is used to specify that the response should be parsed as JSON. The basicAuth function is used to specify the basic authentication credentials.

The responseBody function is used to extract the response body from the response object, and the print function is used to print the response body to the console.

The program output is the following:

{"authenticated":true,"user":"someuser"}

            (basicAuth "someuser" "somepassword")
    print (responseBody response :: Value)
