You can extract any component from the URI using TUriC8::Extract(), passing a TUriComponent flag for example, EUriQuery or EUriPath.

The code fragment shows how to extract a scheme component. Parse the URI before the component is extracted calling TUriParser8::Parse().

_LIT8(KUri,"http://web.intra/Dev/Sysdoc/devlib.htm");
TUriParser8 parser;// Uri parser object
TInt result = parser.Parse(KUri);//parse the Uri descriptor     

//Extract the scheme component from the parsed URI
const TDesC8& des = parser.Extract(EUriScheme);

where des is a descriptor that contains the extracted scheme component. Other components such as userinfo, host, port and so on defined in TUriComponent can be extracted in a similar way.

To retrieve a specific authority component from the URI, call TAuthority8::Extract().

_LIT8(KAuthorityDesc,       "http://user:[email protected]");
TAuthorityParser8 authorityParser;  //authority parser object 

authorityParser.Parse(KAuthorityDesc);  //Parse the authority descriptor    
const TDesC8& des = authorityParser.Extract(EAuthorityUserinfo); //extract the user info from the authority component

where, des contains the user info that is extracted from the authority component. EAuthorityUserinfo is an enum value of TAuthorityComponent. Similarly, host and port can be extracted using EAuthorityHost and EAuthorityPort respectively which are defined in TAuthorityComponent.

To create a new descriptor containing the desired component or the full URI, call TUriC8::DisplayFormL().

This converts a component into a new descriptor. The component to be converted can take any value between EUriScheme and EUriFragment or EUriComplete(for the full URI). This method is used to get a pointer to a 16 bit descriptor for GUI display of URI.

HBufC16* uri= parsedUri->DisplayFormL(EUriComplete);

where EUriComplete indicates that all the components in the URI are displayed.

To fetch the URI, call TUriC8::UriDes(). This returns a pointer to 8 bit descriptor(TDesC8) containing the URI, which is used for HTTP requests.

To create a new descriptor containing a specific component or the full authority component, call TAuthority8::DisplayFormL().

This converts a component into a new descriptor. The component to be converted can take any value between EAuthorityUserinfo and EAuthorityPort or the full authority, EAuthorityComplete.

HBufC authority= parsedUri->DisplayFormL(EAuthorityComplete);

where EAuthorityComplete means that the complete authority is displayed.
