NetworkCredential.GetCredential 方法

定义

命名空间:

System.Net

程序集:

System.Net.Primitives.dll

为指定的身份验证类型返回 NetworkCredential 类的一个实例。

重载

GetCredential(String, Int32, String)	针对指定的主机、端口和身份验证类型返回 NetworkCredential 类的实例。
GetCredential(Uri, String)	针对指定的统一资源标识符 (URI) 和身份验证类型返回 NetworkCredential 类的实例。

GetCredential(String, Int32, String)

Source:

NetworkCredential.cs

针对指定的主机、端口和身份验证类型返回 NetworkCredential 类的实例。

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

参数

host

String

对该客户端进行身份验证的主机。

port

Int32

与客户端通信的 host 上的端口。

authenticationType

String

AuthenticationType 属性中定义的所请求的身份验证类型。

返回

NetworkCredential

指定的主机、端口和身份验证协议的 NetworkCredential；如果指定的主机、端口和身份验证协议没有可用的凭据，则为 null。

实现

GetCredential(String, Int32, String)

注解

的值 authType 对应于 IAuthenticationModule.AuthenticationType 属性。

GetCredential(Uri, String)

Source:

NetworkCredential.cs

针对指定的统一资源标识符 (URI) 和身份验证类型返回 NetworkCredential 类的实例。

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

参数

uri

Uri

客户端为其提供身份验证的 URI。

authenticationType

String

AuthenticationType 属性中定义的所请求的身份验证类型。

返回

NetworkCredential

NetworkCredential 对象。

实现

GetCredential(Uri, String)

示例

下面的代码示例使用 GetCredential 方法检索 NetworkCredential 指定 URI 的对象。

// 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()
