Question

我正在开发一个WCF服务，它将向Xamarin客户端提供数据。我正在尝试使用自定义用户名/密码和自定义原则，以便我可以将服务的可用信息附加到身份。经过多次尝试，我无法在客户端上获得除了不同的错误消息之外的任何内容。我认为问题出在WCF配置中，但我无法弄清问题是什么。我的web.config代码如下。任何有关去哪儿的帮助或提示都将不胜感激！

我在Wamarin解决方案的主项目中使用WFC服务作为连接服务。使用以下代码调用该服务：

        Service.ServiceClient _client;

        _client = new Service.ServiceClient();


        _client.ClientCredentials.UserName.UserName = 
"username";
        _client.ClientCredentials.UserName.Password = "password";

        //To allow service to connect even though certificate was not 
validated.
        ServicePointManager.ServerCertificateValidationCallback = 
MyRemoteCertificateValidationCallback;

        lci = await _client.WCFTestMethod();

更新以下评论的帖子。 Xamarin不支持wsHttpBinding，所以我必须使用basicHttpBinding。当我在IIS站点上将身份验证设置为Anonymous时，我已经执行了checkAccessCore过程，但它会抛出此错误＆＃34; No Identity Found＆＃34;当AuthorizationPolicy执行GetClientIdentity时。有没有办法在checkAccessCore中分配一个身份？

Answer 1

我能够以我想要的方式使服务工作，确保IIS上的身份验证方法设置为Anonymous，并且在AuthorizationPolicy的Evaluate方法中我创建了GenericIdentity并使用它（下面的示例代码）而不是调用GetClientIdentity方法。该服务现在似乎正在运行，并且正在checkAccessCore方法中对用户进行身份验证。

    Dim client As IIdentity = New GenericIdentity("User")

    Dim cp As CustomPrincipal = New CustomPrincipal(client)

    evaluationContext.Properties("Identities") = l


    evaluationContext.Properties("Principal") = cp

XAMARIN，WCF，带有自定义用户名/密码和主体
