정의

네임스페이스:

System.Net

어셈블리:

System.Net.Requests.dll

서버에 인증을 요청하면 Authorization 클래스의 인스턴스를 반환합니다.

public:
 System::Net::Authorization ^ PreAuthenticate(System::Net::WebRequest ^ request, System::Net::ICredentials ^ credentials);

public System.Net.Authorization? PreAuthenticate (System.Net.WebRequest request, System.Net.ICredentials credentials);

abstract member PreAuthenticate : System.Net.WebRequest * System.Net.ICredentials -> System.Net.Authorization

Public Function PreAuthenticate (request As WebRequest, credentials As ICredentials) As Authorization

매개 변수

request

WebRequest

인증 요청과 관련된 WebRequest 인스턴스입니다.

credentials

ICredentials

인증 요청과 관련된 자격 증명입니다.

반환

Authorization

요청에 대한 인증 메시지가 포함된 Authorization 인스턴스입니다.

예제

// The PreAuthenticate method specifies if the authentication implemented
// by this class allows pre-authentication.
// Even if you do not use it, this method must be implemented to obey to the rules
// of interface implemebtation.
// In this case it always returns null.

설명

속성이 CanPreAuthenticate 인 true경우 메서드는 PreAuthenticate 인증 메시지를 포함하는 클래스의 Authorization 인스턴스를 반환합니다.
