As far as I understand, an URL consists of the folowing fields:
- Protocol (http, https, ftp, etc.)
- User name
- User Password
- Host address (an IP address or a DNS FQDN)
- Port (which can be implied)
- Path to a document inside the server documents root
- Set of arguments and values
- Document part (#)
as
protocol://user:password@host:port/path/document?arg1=val1&arg2=val2#part
I need a code to get value (or null/empty value if not set) of any of these fields from any given URL string. Am I to implement this myself or there is already a code for this so I don't need to invent a wheel?
I am particularly interested in Scala or Java code. C#, PHP, Python or Perl code can also be useful.
