Question

我在sharepoint应用程序中使用了wcf服务。但是当我尝试从jquery调用方法时，它总是失败。

我用这样的字符串测试了服务：

ttp://localhost/_vti_bin/webservices/wcfservice.svc/**mex**

并有正常的回应。

WCF测试客户端也有响应。

但是在我的javascript代码中，我总是收到错误。为什么？我做错了什么？

   $.ajax({
        url: "/_vti_bin/webservices/wcfservice.svc/HelloWorld",
        dataType: 'json',
        contentType: "application/json",
        success: function (res) {
            alert("good answer");
        },
        error: function (xhr) {
            alert("error");

            return;
        }
    });

服务守则：

[BasicHttpBindingServiceMetadataExchangeEndpoint]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    [ServiceContract]
    public class WCFService 
    {
        // To test this service, use the Visual Studio WCF Test client
        // set the endpoint to http://<Your server name>/_vti_bin/WebServices/WCFService.svc/mex
        [OperationContract]
        //[WebGet(UriTemplate = "HelloWorld", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
        [WebInvoke(RequestFormat = WebMessageFormat.Json, UriTemplate="/HelloWorldM", BodyStyle = WebMessageBodyStyle.Wrapped)]
        public string HelloWorld()
        {
            return "Hello World from WCF and SharePoint 2010";
        }
    }

Answer 1

尝试在SVC文件中使用MultipleBaseAddressWebServiceHostFactory而不是MultipleBaseAddressBasicHttpBindingServiceHostFactory。
