Authorization Constructor (String^, Boolean, String^)

 

Creates a new instance of the Authorization class with the specified authorization message, completion status, and connection group identifier.

Namespace:   System.Net
Assembly:  System (in System.dll)

public:
Authorization(
	String^ token,
	bool finished,
	String^ connectionGroupId
)

Parameters

token
Type: System::String^

The encrypted authorization message expected by the server.

finished
Type: System::Boolean

The completion status of the authorization attempt. true if the authorization attempt is complete; otherwise, false.

connectionGroupId
Type: System::String^

A unique identifier that can be used to create private client-server connections that are bound only to this authentication scheme.

The following code example creates a new instance of the Authorization class with the specified authorization message, completion status, and connection group identifier.

virtual Authorization^ Authenticate( String^ challenge, WebRequest^ request, ICredentials^ credentials )
{
   try
   {
      String^ message;

      // Check if Challenge String* was raised by a site which requires CloneBasic authentication.
      if ( (challenge == nullptr) || ( !challenge->StartsWith( "CloneBasic" )) )
               return nullptr;
      NetworkCredential^ myCredentials;
      if ( dynamic_cast<CredentialCache^>(credentials) == nullptr )
      {
         myCredentials = credentials->GetCredential( request->RequestUri, "CloneBasic" );
         if ( myCredentials == nullptr )
                     return nullptr;
      }
      else
               myCredentials = dynamic_cast<NetworkCredential^>(credentials);

      // Message encryption scheme :
      // a)Concatenate username and password seperated by space;
      // b)Apply ASCII encoding to obtain a stream of bytes;
      // c)Apply Base64 Encoding to this array of bytes to obtain our encoded authorization message.
      message = String::Concat( myCredentials->UserName, " ", myCredentials->Password );

      // Apply AsciiEncoding to our user name and password to obtain it as an array of bytes.
      Encoding^ asciiEncoding = Encoding::ASCII;
      array<Byte>^byteArray = gcnew array<Byte>(asciiEncoding->GetByteCount( message ));
      byteArray = asciiEncoding->GetBytes( message );

      // Perform Base64 transform.
      message = Convert::ToBase64String( byteArray );

      // The following overloaded contructor sets the 'Message' property of authorization to the base64 String*;
      // that  we just formed and it also sets the 'Complete' property to true and the connection group id;
      // to the domain of the NetworkCredential Object*.
      Authorization^ myAuthorization = gcnew Authorization( String::Concat( "CloneBasic ", message, true, request->ConnectionGroupName ) );
      return myAuthorization;
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception Raised ...: {0}", e->Message );
      return nullptr;
   }
}
