Detailed Description

This abstract class describes the authorisation mechanism for a Universal Resource Locator.

Member Function Documentation

static void PHTTPAuthority::DecodeBasicAuthority ( const PString authInfo,
PString username,
PString password 
)
staticprotected
Parameters
authInfoAuthority information string.
usernameUser name decoded from authInfo
passwordPassword decoded from authInfo
virtual PString PHTTPAuthority::GetRealm ( const PHTTPRequest request) const
pure virtual

Get the realm or name space for the user authorisation name and password as required by the basic authorisation system of HTTP/1.0.

Returns
String for the authorisation realm name.
Parameters
requestRequest information.

Implemented in PHTTPMultiSimpAuth, and PHTTPSimpleAuth.

virtual PBoolean PHTTPAuthority::IsActive ( ) const
virtual

Determine if the authorisation is to be applied.

This could be used to distinguish between net requiring authorisation and requiring autorisation but having no password.

The default behaviour is to return true.

Returns
true if the authorisation in the realm is to be applied.

Reimplemented in PHTTPMultiSimpAuth, and PHTTPSimpleAuth.

virtual PBoolean PHTTPAuthority::Validate ( const PHTTPRequest request,
const PString authInfo 
) const
pure virtual

Validate the user and password provided by the remote HTTP client for the realm specified by the class instance.

Returns
true if the user and password are authorised in the realm.
Parameters
requestRequest information.
authInfoAuthority information string.

Implemented in PHTTPMultiSimpAuth, and PHTTPSimpleAuth.
