通过

WebClientProtocol.Credentials 属性

  • 参考

定义

命名空间:
System.Web.Services.Protocols
程序集:
System.Web.Services.dll

获取或设置 XML Web services 客户端身份验证的安全凭据。

public:
 property System::Net::ICredentials ^ Credentials { System::Net::ICredentials ^ get(); void set(System::Net::ICredentials ^ value); };
public System.Net.ICredentials Credentials { get; set; }
member this.Credentials : System.Net.ICredentials with get, set
Public Property Credentials As ICredentials

属性值

ICredentials

XML Web services 客户端的 ICredentials。

示例

以下示例是一个 ASP.NET Web 窗体，它调用名为 的 MathXML Web 服务。 在 EnterBtn_Click 函数中，Web 窗体使用 Credentials 属性显式设置身份验证凭据。 用户名、密码和域将传递到 类的构造函数中 NetworkCredential 。

重要

此示例具有一个接受用户输入的文本框，这是一个潜在的安全威胁。 默认情况下，ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。 有关详细信息，请参阅：

注解

使用 Credentials 属性时，XML Web 服务客户端必须实例化实现 ICredentials的类，例如 NetworkCredential，然后设置特定于身份验证机制的客户端凭据。 类 NetworkCredential 可用于使用基本、摘要、NTLM 和 Kerberos 身份验证机制设置身份验证凭据。

如果将 Credentials 属性设置为 CredentialCache.DefaultCredentials，则客户端将与服务器进行协商，并根据服务器的配置方式执行 Kerberos 和/或 NTLM 身份验证。
