c#之CRM 2011 SecurityNegotiationException 尝试访问 Web 服务_编程设计

尝试连接到 CRM 2011 Web 服务时出现意外错误。这是背景:

连接字符串(已删除敏感信息):"ServiceUri=https://crmdomain.com/OrgName/XRMServices/2011/Organization.svc; Url=https://crmdomain.com/OrgName; Username= appusername; Password=hidden"/>

按如下方式创建连接:

将conn字符串解析成CRMConnection:var conn = Microsoft.Xrm.Client.CrmConnection.Parse(connString);(此时，CrmConnection对象中的属性看起来正确，包括 ClientCredentials)
创建组织代理:var orgProxy = new OrganizationServiceProxy(conn.ServiceUri, conn.HomeRealmUri, conn.ClientCredentials, conn.DeviceCredentials);
创建数据上下文:var context = new MyContext(orgProxy);

此时，当从 context 中检索任何数据时，会发生以下 WCF 异常:

发生System.ServiceModel.Security.SecurityNegotiationException Message=调用者未通过服务的身份验证。 来源=mscorlib 堆栈跟踪: 服务器堆栈跟踪: 在 System.ServiceModel.Security.IssuanceTokenProviderBase'1.DoNegotiation(TimeSpan 超时) 在 System.ServiceModel.Security.SspiNegotiationTokenProvider.OnOpen(TimeSpan 超时) 在 System.ServiceModel.Security.WrapperSecurityCommunicationObject.OnOpen(TimeSpan 超时)

...等等。

InnerException 显示 IsSenderFault=True 和 IsPredefinedFault=True。

这是怎么回事？

请您参考如下方法:

我找到了解决方案。首先请下载 CRM SDK 2011 的 RTW 版本。

连接代码将是:

public static IOrganizationService Service()  
{ 
    ClientCredentials Credentials = new ClientCredentials();  
    Credentials.Windows.ClientCredential.UserName ="<username>";  
    Credentials.Windows.ClientCredential.Password ="<password>";  
 
    //This URL needs to be updated to match the servername and Organization for the environment. 
    Uri OrganizationUri = new Uri("http://<server name>/<organization name>/XRMServices/2011/Organization.svc");  
    Uri HomeRealmUri = null;  
 
    //OrganizationServiceProxy serviceProxy;  
    using (OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(OrganizationUri, HomeRealmUri, Credentials, null))  
    { 
        IOrganizationService service = (IOrganizationService)serviceProxy;  
        return service;  
    } 
}

给你...

干杯!享受编码。
