我还查看并确认了我的设置:http://www.asp.net/AJAX/documentation/live/ConfiguringASPNETAJAX.aspx
这是我的代码(ASMX代码后台):
namespace RivWorks.Web.Services
{
/// <summary>
/// Summary description for Negotiate
/// </summary>
[WebService(Namespace = "http://rivworks.com/webservices/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[ScriptService]
public class Negotiate : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public RivWorks.Data.Objects.rivProduct GetSetup(string jsonInput)
{
// Deserialize the input and get all the data we need...
// TODO: This is a quick hack just to work with this for now...
char[] tokens = { '(', '{', '}', ')', ',', '"' };
string[] inputs = jsonInput.Split(tokens);
string inputRef = "";
string inputDate = "";
string inputProductID = "";
for (int i = 0; i < inputs.Length; i++)
{
if (inputs[i].Equals("ref", StringComparison.CurrentCultureIgnoreCase))
inputRef = inputs[i+2];
if (inputs[i].Equals("dt", StringComparison.CurrentCultureIgnoreCase))
inputDate = inputs[i+2];
if (inputs[i].Equals("productid", StringComparison.CurrentCultureIgnoreCase))
inputProductID = inputs[i+2];
}
Guid pid = new Guid(inputProductID);
RivWorks.Data.Objects.rivProduct product = RivWorks.Data.rivProducts.GetProductById(pid);
return product;
}
}
当我从本地主机运行时,我得到了这个结果集:
<ResultSet>
<uiType>modal</uiType>
<width>775</width>
<height>600</height>
<swfSource>
http://localhost.rivworks.com/flash/negotiationPlayer.swf
</swfSource>
<buttonConfig>
http://cdn1.rivworks.com/Element/Misc/734972de-40ae-45f3-9610-5331ddd6e8f8/apple-logo-2.jpg
</buttonConfig>
</ResultSet>
我错过了什么???
注意:我正在使用3.5框架(或者至少我认为我在用,因为我的web.config中的所有内容都标记为3.5.0.0)
更新:我正在浏览服务并使用该页面上的输入框。您可以在此处尝试:http://dev.rivworks.com/services/Negotiate.asmx?op=GetSetup。我们还尝试从在另一个站点上运行的基于JS的Web应用程序访问它(这个特定服务的主要目的)。我这里没有那个代码。(抱歉,测试表单仅在本地主机上可用。)
更新:我添加了以下测试页面(JsonTest.htm)以尝试查看来回传输的内容。但是我只收到500错误!我甚至尝试附加到进程并中断我的服务。但是在ASP管道进入我的代码之前就会抛出500错误。

更新:通过WCF服务进行工作。这是我的设置: 接口:

现在我遇到了这个错误:
IIS指定的身份验证方案为“IntegratedWindowsAuthentication,Anonymous”,但绑定只支持指定一个身份验证方案。有效的身份验证方案包括Digest、Negotiate、NTLM、Basic或Anonymous。更改IIS设置,仅使用单个身份验证方案。我该如何处理? <state emotion='wrung out' physical='beat up' />
