web-services - SharePoint 2013 中的自定义 Web 服务与模拟

Question

对于 SharePoint 2010，我们使用自定义 Web 服务(不是 SOAP!)使一些第 3 方数据可用于浏览器显示的页面中的 JS 代码。这是敏感数据，因此我们使用模拟来确保只有正确的用户才能访问它。我们的解决方案在 SharePoint 2013 中不再适用。由于原始解决方案相当复杂，我在 SP 2013 中构建了一个小而简单的服务，以研究如何设置具有模拟的 Web 服务。该服务部署到 ISAPI 的子文件夹。

这是没有模仿的基础，它有效:

测试服务.svc:

<%@ ServiceHost 
    Language="C#"
    Debug="true" 
    Service="Sandbox.TestService, $SharePoint.Project.AssemblyFullName$" 
    CodeBehind="TestService.svc.cs" 
    Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressWebServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

TestService.svc.cs 后面的代码是:

using Microsoft.SharePoint.Client.Services;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Activation;
using System.ServiceModel;
using System.ServiceModel.Web;

namespace Sandbox
{
    [ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class TestService
    {
        [OperationContract]
        [WebGet(UriTemplate = "GetAllNumbers",
            ResponseFormat = WebMessageFormat.Json)]
        List<int> GetAllNumbers()
        {
            List<int> result = new List<int>();
            result.AddRange(new[] { 1, 1, 2, 3, 5, 8, 13 });
            return result;
        }
    }
}

当我在 http://pc00175/_vti_bin/Sandbox/TestService.svc/GetAllNumbers 上执行 GET 时我收到了预期的共鸣 [1,1,2,3,5,8,13] .到目前为止还好。现在我尝试使用模拟:

using Microsoft.SharePoint.Client.Services;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Activation;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Security.Principal;

namespace Sandbox
{
    [ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class TestService
    {
        [OperationContract]
        [WebGet(UriTemplate = "GetAllNumbers",
            ResponseFormat = WebMessageFormat.Json)]
        List<int> GetAllNumbers()
        {
            List<int> result = new List<int>();
            WindowsImpersonationContext ctx = ServiceSecurityContext.Current.WindowsIdentity.Impersonate();
            try
            {
                result.AddRange(new[] { 1, 1, 2, 3, 5, 8, 13 });
            }
            finally
            {
                ctx.Undo();
            }
            return result;
        }
    }
}

现在我得到一个 System.InvalidOperationException 消息“匿名身份无法执行模拟”。调用 ServiceSecurityContext.Current.WindowsIdentity.Impersonate() 时.我需要告诉 WCF 我们需要模拟该调用。所以我添加了一个属性 [OperationBehavior(Impersonation=ImpersonationOption.Required)] :

using Microsoft.SharePoint.Client.Services;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Activation;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Security.Principal;

namespace Sandbox
{
    [ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class TestService
    {
        [OperationContract]
        [WebGet(UriTemplate = "GetAllNumbers",
            ResponseFormat = WebMessageFormat.Json)]
        [OperationBehavior(Impersonation=ImpersonationOption.Required)]
        List<int> GetAllNumbers()
        {
            List<int> result = new List<int>();
            WindowsImpersonationContext ctx = ServiceSecurityContext.Current.WindowsIdentity.Impersonate();
            try
            {
                result.AddRange(new[] { 1, 1, 2, 3, 5, 8, 13 });
            }
            finally
            {
                ctx.Undo();
            }
            return result;
        }
    }
}

现在我在 SharePoint 日志中发现以下错误:

Error when open web service: System.InvalidOperationException: The contract operation 'GetAllNumbers' requires Windows identity for automatic impersonation. A Windows identity that represents the caller is not provided by binding ('WebHttpBinding','http://tempuri.org/') for contract ('TestService','http://tempuri.org/'.     at System.ServiceModel.Dispatcher.SecurityValidationBehavior.WindowsIdentitySupportRule.ValidateWindowsIdentityCapability(Binding binding, ContractDescription contract, OperationDescription operation)     at System.ServiceModel.Dispatcher.SecurityValidationBehavior.WindowsIdentitySupportRule.Validate(ServiceDescription description)     at System.ServiceModel.Dispatcher.SecurityValidationBehavior.System.ServiceModel.Description.IServiceBehavior.Validate(ServiceDescriptio...

然后我猜我必须在 TestService.svc 旁边添加一个 web.config 并添加 TransportCredentialsOnly 模式，但这没有帮助:

<?xml version="1.0"?>
<configuration>
  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding>
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Ntlm"/>
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

我在 SharePoint 日志文件中收到相同的错误。

我希望有人对我有提示。

谢谢你读到这里!

如果你想使用 REST，为什么不简单地为此创建一个应用程序呢？这比在 SharePoint 中公开 WCF 服务要容易得多。然后，您可以配置自己的安全设置。
