Ajax调用:

   $.ajax({
        type: "POST",
        url: "http://SomeService/ServiceName.svc/GetSearchResults",
        data: JSON.stringify({ parameters: serviceParameters }),
        contentType: "application/json; charset=utf-8",
        dataType: "XML",
        success: function (response) {
            $("#xmlText").text(response.xml);
        },
        error: function (msg) {
            alert(msg.toString);
        }
    })

WCF接口:

[OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Xml, RequestFormat = WebMessageFormat.Json,
                    UriTemplate = "GetSearchResults")]
        XElement GetSearchResults(inputParameters parameters);

        [OperationContract]
        [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, UriTemplate = "getFile")]
        Stream GetFile(DocInfo info);
