Sharepoint 2010 wcf服务。使用jquery调用方法

我有wcf服务在sharepoint应用程序中崩溃。但是当我尝试从jquery调用方法时，它总是失败。与这样的字符串Sharepoint 2010 wcf服务。使用jquery调用方法

我已经测试服务：

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

和有正常的反应。

WCF测试客户端也有响应。

但在我的JavaScript代码，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; 
     } 
    });

浏览器响应：

....什么错误？ – Shoban 2011-02-23 19:06:29

警报（“错误”）; xhr.responseText为空 – Evgeny 2011-02-23 19:09:47

xhr.status的值是多少，您的服务实际上是否存在。 – RobertPitt 2011-02-23 19:14:51

尝试使用MultipleBaseAddressWebServiceHostFactory代替MultipleBaseAddressBasicHttpBindingServiceHostFactory在SVC文件。

1）我无法访问web.config。因为sharepoint和第二我可以达到所有方法从wcf测试客户端。所以我认为这是可能的从ajax做。但是，url应该如何看起来像？ – Evgeny 2011-02-23 19:25:03

为什么不能访问web.config？ – Shoban 2011-02-23 19:30:09

它就像另一个asp.net web应用程序。 – Shoban 2011-02-23 19:36:06
