How do I parse a web URL?

Question

I need to be able to break a URL down into different segments. Take this path for example:

http://login:password@somehost.somedomain.com:8080/some_path/somet         


        

Answer 1

XE2 ships with Indy, which has a TIdURI class for that purpose, eg:

uses
  ..., IdURI;

var
  URI: TIdURI;

URI := TIdURI.Create('http://login:password@somehost.somedomain.com:8080/some_path/something_else.html?param1=val¶m2=val');
try
  // Protocol = URI.Protocol
  // Username = URI.Username
  // Password = URI.Password
  // Host = URI.Host
  // Port = URI.Port
  // Path = URI.Path
  // Query = URI.Params
finally
  URI.Free;
end;
