GetCredential(String, Int32, String)

來源:

NetworkCredential.cs

傳回指定主機、連接埠和驗證類型之 NetworkCredential 類別的執行個體。

public:
 virtual System::Net::NetworkCredential ^ GetCredential(System::String ^ host, int port, System::String ^ authenticationType);

public System.Net.NetworkCredential GetCredential (string? host, int port, string? authenticationType);

abstract member GetCredential : string * int * string -> System.Net.NetworkCredential
override this.GetCredential : string * int * string -> System.Net.NetworkCredential

Public Function GetCredential (host As String, port As Integer, authenticationType As String) As NetworkCredential

參數

host

String

驗證用戶端的主機電腦。

port

Int32

用戶端將與之通訊的 host 連接埠。

authenticationType

String

要求驗證的類型，如同在 AuthenticationType 屬性中的定義。

傳回

NetworkCredential

指定主機、連接埠和驗證通訊協定的 NetworkCredential，如果指定主機、連接埠和驗證通訊協定沒有認證，則為 null。

實作

GetCredential(String, Int32, String)

備註

的值 authType 會對應至 IAuthenticationModule.AuthenticationType 屬性。

GetCredential(Uri, String)

public:
 virtual System::Net::NetworkCredential ^ GetCredential(Uri ^ uri, System::String ^ authenticationType);

public System.Net.NetworkCredential GetCredential (Uri? uri, string? authenticationType);

abstract member GetCredential : Uri * string -> System.Net.NetworkCredential
override this.GetCredential : Uri * string -> System.Net.NetworkCredential

Public Function GetCredential (uri As Uri, authenticationType As String) As NetworkCredential

參數

uri

Uri

用戶端為其提供驗證的 URI。

authenticationType

String

要求驗證的類型，如同在 AuthenticationType 屬性中的定義。

傳回

NetworkCredential

NetworkCredential 物件。

實作

GetCredential(Uri, String)

範例

下列程式代碼範例會 GetCredential 使用 方法來擷取 NetworkCredential 指定 URI 的物件。

// Create an empty instance of the NetworkCredential class.
NetworkCredential^ myCredentials = gcnew NetworkCredential( userName,password );

// Create a webrequest with the specified URL.
WebRequest^ myWebRequest = WebRequest::Create( url );
myWebRequest->Credentials = myCredentials->GetCredential( gcnew Uri( url ), "" );
Console::WriteLine( "\n\nUser Credentials:- UserName : {0} , Password : {1}",
   myCredentials->UserName, myCredentials->Password );

// Send the request and wait for a response.
Console::WriteLine( "\n\nRequest to Url is sent.Waiting for response...Please wait ..." );
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Process the response.
Console::WriteLine( "\nResponse received successfully" );

// Release the resources of the response object.
myWebResponse->Close();

// Create an empty instance of the NetworkCredential class.
NetworkCredential myCredentials = new NetworkCredential(userName,password);
// Create a webrequest with the specified URL.
WebRequest myWebRequest = WebRequest.Create(url);
myWebRequest.Credentials = myCredentials.GetCredential(new Uri(url),"");
Console.WriteLine("\n\nUser Credentials:- UserName : {0} , Password : {1}",myCredentials.UserName,myCredentials.Password);
// Send the request and wait for a response.
Console.WriteLine("\n\nRequest to Url is sent.Waiting for response...Please wait ...");
WebResponse myWebResponse = myWebRequest.GetResponse();
// Process the response.
   Console.WriteLine("\nResponse received successfully");
// Release the resources of the response object.
myWebResponse.Close();

' Create an empty instance of the NetworkCredential class.
Dim myCredentials As New NetworkCredential(userName, password)
' Create a WebRequest with the specified URL. 
Dim myWebRequest As WebRequest = WebRequest.Create(url)
' GetCredential returns the same NetworkCredential instance that invoked it, 
' irrespective of what parameters were provided to it. 
 myWebRequest.Credentials = myCredentials.GetCredential(New Uri(url), "")
Console.WriteLine(ControlChars.Cr + ControlChars.Cr + "User Credentials:- UserName : {0} , Password : {1}", myCredentials.UserName, myCredentials.Password)
' Send the request and wait for a response.
Console.WriteLine(ControlChars.Cr + ControlChars.Cr + "Request to Url is sent.Waiting for response...Please wait ...")
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
' Process the response.
Console.WriteLine(ControlChars.Cr + "Response received successfully")
' Release the resources of the response object.
myWebResponse.Close()
