Sharepoint 2010 WCF服務的問題

Question

我需要為sharepoint 2010創建wcf服務。使用Jquery ajax與此服務進行通信的想法。 但所有服務方法的cals總是失敗。 該

我嘗試使用WCF測試客戶端並獲取消息：

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.

和錯誤細節：

    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.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)

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

Exception rethrown at [0]:

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

但服務http：//localhost/_vti_bin/site/TEMPSERVICE.svc/mex是可用的，並給我正常的響應。

根據msdn上的文章做的一切

問題是什么以及如何處理它？

葉夫根尼：

看起來您的webservice返回標准SOAP XML響應。 JQuery希望使用JSON。 我認為更簡單的方法是將JQuery設置為使用XML。 或者，您可以更改Web服務以返回JSON而不是XML。
