从jQuery

Question

我试图从jQuery访问Windows托管的WCF。我在使用POST时无法访问发送到服务器的数据。所以我用'GET＆＃39;并能够将数据发布到服务器。但客户端没有收到服务器的响应。我得到了Cross-Origin＆＃39;请求被阻止＆＃39;错误。

jQuery客户端代码

function callWCF() {
var obj = {};
obj.data = "XLGS";
var inputData = JSON.stringify(obj);
var url = 'http://localhost:8733/TestService/GetData?value=' + 'test';
$.ajax({
    type: 'GET',
    url: url,
    data: {},
    //data: { parameters: "{'process':'AutoComplete', 'getall':'false'}" },
    contentType: '',
    dataType: '',
    success: function (httpResponse) {
        alert("Success");
    },
    error: function (httpResponse) {
        alert("Error");
    }
});}

WCF服务代码

[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml)]
    public string GetData(string value)
    {
        return value + " Response from service";
    }

WCF主机配置

        <add baseAddress="http://localhost:8733/TestService"/>
      </baseAddresses>
    </host>
  </service>
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

<!--<services>
  <service name="WCFAjax.GateWayService">

      </baseAddresses>

  </service>

何解决？
