【问题标题】:Authentication failed while calling WCF service from ASP.NET从 ASP.NET 调用 WCF 服务时身份验证失败
【发布时间】:2011-11-22 05:34:26
【问题描述】:

平台:VS 2008、.NET 3.5、C#、Oracle 11g

我创建了一个 WCF 服务,它获取一些数据元素,然后将它们插入数据库表并返回一个整数。我还创建了一个小型 ASP.NET Web 应用程序来测试该服务。测试 Web 应用只有一个包含字段和按钮的页面,单击该按钮实际上会调用 Web 服务来插入数据并返回一个整数值。

我采取的步骤:

  • 构建 WCF 服务
  • 发布 WCF 服务
  • 使用 svcutil 生成代理类 (.cs) 和 app.config
  • 构建测试 asp.net 应用并添加上述步骤中生成的代理类和配置设置。
  • 破坏测试应用

当我在我的计算机(Windows XP、IIS 5.1)上同时部署 WCF 和测试 Web 应用程序时,它工作正常。但是,每当我尝试将它们部署在远程服务器上时,它都不起作用。当我尝试使用该服务(部署在远程服务器 - Windows 2003 服务器、IIS 6 上)时,我收到以下错误:

无法满足对安全令牌的请求,因为 身份验证失败。

异常详细信息:System.ServiceModel.FaultException:请求 由于身份验证失败,无法满足安全令牌。

以下是 .config 文件内容:

调用 ASP.NET Web 应用(Consumer)的 Web.Config 的 wcf 部分:

    【解决方案1】:

    可能与wcf服务的安全配置有关,具体来说,Windows凭据类型需要有效的域用户名和密码信息。

    尝试在客户端提供以下属性;

    proxy.ClientCredentials.Windows.ClientCredential.UserName = "UserName ";
    proxy.ClientCredentials.Windows.ClientCredential.Password = "Password ";
    proxy.ClientCredentials.Windows.ClientCredential.Domain = "Domain ";
