Sharepoint 2010 WCF服务的问题

Question

我需要为sharepoint 2010创建wcf服务。使用Jquery ajax与此服务进行通信的想法。 但所有服务方法的cals总是失败。 该

我尝试使用WCF测试客户端并获取消息：

Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.

和错误细节：

    The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 227 bytes of the response were: 'A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - Either a required impersonation level was not provided, or the provided impersonation level is invalid.)'.

Server stack trace: 
   at System.ServiceModel.Channels.HttpChannelUtilities.ValidateRequestReplyResponse(HttpWebRequest request, HttpWebResponse response, HttpChannelFactory factory, WebException responseException, ChannelBinding channelBinding)

   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
   at ITV2WCFService.DoWork()
   at TV2WCFServiceClient.DoWork()

但服务http：//localhost/_vti_bin/site/TEMPSERVICE.svc/mex是可用的，并给我正常的响应。

根据msdn上的文章做的一切

问题是什么以及如何处理它？

Answer 1

叶夫根尼：

看起来您的webservice返回标准SOAP XML响应。 JQuery希望使用JSON。 我认为更简单的方法是将JQuery设置为使用XML。 或者，您可以更改Web服务以返回JSON而不是XML。
