NetworkCredential 类

  • 项目

为基于密码的身份验证方案（如基本、简要、NTLM 和 Kerberos 身份验证）提供凭据。

**命名空间:**System.Net
**程序集:**System（在 system.dll 中）

语法

声明
Public Class NetworkCredential
    Implements ICredentials, ICredentialsByHost
用法
Dim instance As NetworkCredential

public class NetworkCredential : ICredentials, ICredentialsByHost

public ref class NetworkCredential : ICredentials, ICredentialsByHost

public class NetworkCredential implements ICredentials, ICredentialsByHost

public class NetworkCredential implements ICredentials, ICredentialsByHost

备注

NetworkCredential 类是为基于密码的身份验证方案（如基本、简要、NTLM 和 Kerberos）提供凭据的基类。实现 ICredentials 接口的类（如 CredentialCache 类）返回 NetworkCredential 对象。

此类不支持基于公钥的身份验证方法，如安全套接字层 (SSL) 客户端身份验证。

示例

下面的代码示例将 NetworkCredential 对象与 CredentialCache 中的一组统一资源标识符 (URI) 相关联。它随后将 CredentialCache 传递给 WebRequest 对象，后者使用此信息对向 Internet 服务器发出的请求进行身份验证。

Dim myCred As New NetworkCredential(SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain )
       
Dim myCache As New CredentialCache()
       
myCache.Add(New Uri("www.contoso.com"), "Basic", myCred)
myCache.Add(New Uri("app.contoso.com"), "Basic", myCred)
       
Dim wr As WebRequest = WebRequest.Create("www.contoso.com")
wr.Credentials = myCache

NetworkCredential myCred = new NetworkCredential(
    SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain);
 
CredentialCache myCache = new CredentialCache();
 
myCache.Add(new Uri("www.contoso.com"), "Basic", myCred);
myCache.Add(new Uri("app.contoso.com"), "Basic", myCred);
 
WebRequest wr = WebRequest.Create("www.contoso.com");
wr.Credentials = myCache;

NetworkCredential^ myCred = gcnew NetworkCredential(
   SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain );

CredentialCache^ myCache = gcnew CredentialCache;

myCache->Add( gcnew Uri( "www.contoso.com" ), "Basic", myCred );
myCache->Add( gcnew Uri( "app.contoso.com" ), "Basic", myCred );

WebRequest^ wr = WebRequest::Create( "www.contoso.com" );
wr->Credentials = myCache;

NetworkCredential myCred =new NetworkCredential(securelyStoredUserName,
    securelyStoredPassword,securelyStoredDomain);
CredentialCache myCache = new CredentialCache();

myCache.Add(new Uri("www.contoso.com"), "Basic", myCred);
myCache.Add(new Uri("app.contoso.com"), "Basic", myCred);

WebRequest wr = WebRequest.Create("www.contoso.com");
wr.set_Credentials(myCache);

var myCred : NetworkCredential = new NetworkCredential(
   SecurelyStoredUserName, SecurelyStoredPassword, SecurelyStoredDomain )
       
var myCache : CredentialCache = new CredentialCache()
       
myCache.Add(new Uri("www.contoso.com"), "Basic", myCred)
myCache.Add(new Uri("app.contoso.com"), "Basic", myCred)
       
var wr : WebRequest = WebRequest.Create("www.contoso.com")
wr.Credentials = myCache
