本文介绍了使用Windows身份验证的WCF jsonP - 可能吗?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在托管输出jsonp的wcf服务。 IIS的响应(启用了Windows身份验证)是

I am hosting a wcf service which outputs jsonp. The response from IIS (with windows authentication turned on) is

经过身份验证的服务不支持跨域javascript回调。

Cross domain javascript callback is not supported in authenticated services.

有办法解决这个问题吗?我必须打开Windows身份验证,但是也想使用wcf来服务我的jsonp

Is there a way to work around this? I must have windows authentication turned on but would like to use wcf as well to server my jsonp

我的网络配置如下

<system.serviceModel>
  <behaviors>
    <endpointBehaviors>
      <behavior name="webHttpBehavior">
        <webHttp />
      </behavior>
    </endpointBehaviors>
  </behaviors>
  <bindings>
    <webHttpBinding>
      <binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" >
        <security mode="TransportCredentialOnly">
          <transport clientCredentialType="Ntlm"/>
        </security>
      </binding>
    </webHttpBinding>
  </bindings>
  <services>
    <service name="ServiceSite.CustomersService">
      <endpoint address="" binding="webHttpBinding"
                bindingConfiguration="webHttpBindingWithJsonP" contract="ServiceSite.CustomersService"
                behaviorConfiguration="webHttpBehavior"/>
    </service>
  </services>
</system.serviceModel>


推荐答案

有点晚了,我知道,但是因为有没有发布答案,我遇到了类似的问题:

A bit late, I see, but since there are no answers posted and I encountered a similar problem:

我能够使用从Windows访问的经过Windows身份验证的WCF服务(在IIs 7.5中托管)的唯一方法跨域客户端是让客户端通过代理进行调用。有一个额外的跳回代理,但现在我不再依赖JSONP。该服务设置了两个端点,soap和json - 我将整个serviceModel卡在底部以供参考。

The only way I was able to use a windows-authenticated WCF service (hosted in IIs 7.5) that was accessed from a cross-domain client was to have the clients call through a proxy. There’s an extra hop back to the proxy, but now I no longer rely on JSONP. The service is setup with two endpoints, soap and json – I stuck the entire serviceModel at the bottom for reference.

所以客户端应用程序(都是.NET网络应用程序) )或者:

So the client apps (which are all .NET web apps) either:

A)对页面方法(或[HttpPost] MVC控制器方法)进行$ .ajax POST,该方法将WCF称为soap Web引用:

A) Make an $.ajax POST to a page method (or [HttpPost] MVC controller method) which calls the WCF as a soap web reference:

function EmployeeSearch() {
    var searchname = $("#userSearchText").val();
    if (searchname.length > 0) {
        var d = { name: searchname, pageSize: _pageSize, page: _currentPage };
        var jsonData = JSON.stringify(d);
        if (json.length > 0) {
            $.ajax({
                type: "POST",
                url: "Home/EmployeeSearch",
                data: jsonData,
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: employeeSearchSuccess,
                error: onError
            });
        }
    }
}

和控制器方法(或页面方法):

And the controller method (or page method):

    [HttpPost]
    public ActionResult EmployeeSearch(string name, int pageSize, int page)
    {
        var client = new EmployeeServiceClient();
        var searchResult = client.EmployeeSearch(name);
        var count = searchResult.Count();
        var employees = searchResult.Skip((page - 1) * pageSize).Take(pageSize).ToList();

        var viewModel = new EmployeeSearchViewModel
                            {
                                Employees = employees,
                                Size = count
                            };

        return Json(viewModel);
    }

OR

B)为HttpHandler创建$ .getJSON,如Dave Wards中所述

B) Make a $.getJSON to an HttpHandler, as described in Dave Wards http://encosia.com/use-asp-nets-httphandler-to-bridge-the-cross-domain-gap/

在上面的示例中,处理程序的ProcessRequest方法中的WebClient.DownoadString()将采用以下url字符串:

In the example above the WebClient.DownoadString() in the handler’s ProcessRequest method would take the following url string:

这两种方法都允许我的服务保持在Windows身份验证下,并且客户端有一些访问服务的方法。额外的跳是令人生气的,但我尽量不考虑它。

Both approaches allow my service to remain under windows auth and the clients have a couple means of accessing the service. The extra hop is irritating, but I try not to think about it.

这里是整个WCF serviceModel供参考:

And here’s the entire WCF serviceModel for reference:

<behaviors>
    <serviceBehaviors>
        <behavior name="EmployeeServiceBehavior">
            <serviceTimeouts transactionTimeout="01:00:00"/>

            <serviceDebug includeExceptionDetailInFaults="true"/>
            <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
        </behavior>
    </serviceBehaviors>

一个补充 - 上述示例方法的OperationContract在ServiceContract中设置如下:

One addition - the OperationContract for the above sample method is setup as follows in the ServiceContract:

    [OperationContract]
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "EmployeeSearch/{name}")]
    List<Employee> EmployeeSearch(string name);
