Ajax呼叫无效 - 从商家交易页面收集信息

Question

我是Ajax的新手。我希望在付款处理后从商家网站检索交易详情。我的ajax调用脚本无效。请帮忙。

C＃方法

public class RetrieveCache
{
    [WebMethod]
    public string RetrieveTransactionData(string ID)
    {
        ChannelFactory<ServiceSoap> PayChannelFactory = new ChannelFactory<ServiceSoap>("ServiceSoap12");
        ServiceSoap Paychannel = PayChannelFactory.CreateChannel();
        XmlNode node = Paychannel.RetrieveCachedData(ID);
        return node.InnerXml;
    }
}

Ajax调用HTML页面中的脚本来调用上面的c＃方法

Html Page URL: http://localhost:55014/SuccessPage.html?id=29473740923

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            var url = window.location.search;
            debugger;
            var token = (url.replace("?", "").split("=")[1]).toString();
            debugger;
            var dataval = JSON.stringify({ token: token });
            $.ajax({
                url: "http://localhost:55014/RetrieveCache.cs/RetrieveTransactionData",
                type: 'post',
                data: JSON.stringify({ token: token }),
                contentType: 'application/json; charset=utf-8',
                dataType: 'json',
                success: function(data){

                        alert(data);

                },
                error: function (err) {
                    alert(err)
                }
            });
        });
    </script>
