Authorization Constructor (String)

Creates a new instance of the Authorization class with the specified authorization message.

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

	String^ token


Type: System::String
The encrypted authorization message expected by the server.

The Authorization instance is created with the Message property set to token and the Complete property set to true.

The following code example shows how to create an Authorization object. For a complete example, refer to the AuthenticationManager class.

   // Authenticate is the core method for this custom authentication.
   // When an internet resource requests authentication, the WebRequest::GetResponse
   // method calls the AuthenticationManager::Authenticate method. This method, in
   // turn, calls the Authenticate method on each of the registered authentication
   // modules, in the order they were registered. When the authentication is
   // complete an Authorization object is returned to the WebRequest, as
   // shown by this routine's retun type.
   virtual Authorization^ Authenticate( String^ challenge, WebRequest^ request, ICredentials^ credentials )
      Encoding^ ASCII = Encoding::ASCII;

      // Get the username and password from the credentials
      NetworkCredential^ MyCreds = credentials->GetCredential( request->RequestUri, "Basic" );
      if ( PreAuthenticate( request, credentials ) == nullptr )
            Console::WriteLine( "\n Pre-authentication is not allowed." );
            Console::WriteLine( "\n Pre-authentication is allowed." );

      // Verify that the challenge satisfies the authorization requirements.
      bool challengeOk = checkChallenge( challenge, MyCreds->Domain );
      if (  !challengeOk )
            return nullptr;

      // Create the encrypted string according to the Basic authentication format as
      // follows:
      // a)Concatenate username and password separated by colon;
      // b)Apply ASCII encoding to obtain a stream of bytes;
      // c)Apply Base64 Encoding to this array of bytes to obtain the encoded
      // authorization.
      String^ BasicEncrypt = String::Concat( MyCreds->UserName, ":", MyCreds->Password );
      String^ BasicToken = String::Concat( "Basic ", Convert::ToBase64String( ASCII->GetBytes( BasicEncrypt ) ) );

      // Create an Authorization object using the above encoded authorization.
      Authorization^ resourceAuthorization = gcnew Authorization( BasicToken );

      // Get the Message property which contains the authorization string that the
      // client returns to the server when accessing protected resources
      Console::WriteLine( "\n Authorization Message: {0}", resourceAuthorization->Message );

      // Get the Complete property which is set to true when the authentication process
      // between the client and the server is finished.
      Console::WriteLine( "\n Authorization Complete: {0}", resourceAuthorization->Complete );

      Console::WriteLine( "\n Authorization ConnectionGroupId: {0}", resourceAuthorization->ConnectionGroupId );
      return resourceAuthorization;
