我在这里要疯了。我查看了以下条目并none他们中的一些人正在纠正我所看到的异常行为:
- 如何从 2.0 asmx Web 服务返回 JSON https://stackoverflow.com/questions/288850/how-to-return-json-from-a-2-0-asmx-web-service
- 如何从 ASP.NET .asmx 返回 JSON? https://stackoverflow.com/questions/1678101/how-to-return-json-from-asp-net-asmx
- 如何让 ASMX 文件输出 JSON https://stackoverflow.com/questions/211348/how-to-let-an-asmx-file-output-json
我也查看并确认了我的设置:http://www.asp.net/AJAX/documentation/live/ConfiguringASPNETAJAX.aspx http://www.asp.net/AJAX/documentation/live/ConfiguringASPNETAJAX.aspx
这是我的代码(后面的 ASMX 代码):
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;
}
}
当我从本地主机实例运行此命令时,我得到以下结果集:
<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(或者至少我认为我是这样,因为我的 web.config 中的所有内容都标记为 3.5.0.0)
更新:我正在浏览该服务并使用该页面上的输入框。您可以在这里尝试:http://dev.rivworks.com/services/Negotiate.asmx?op=GetSetup http://dev.rivworks.com/services/Negotiate.asmx?op=GetSetup。我们还尝试从另一个站点上运行的基于 JS 的 Web 应用程序访问它(此特定服务的主要目的)。我这里没有相关代码。 (抱歉,测试表格只能从本地主机获得。)
更新:我添加了以下测试页面(JsonTest.htm)来尝试查看来回发生了什么。我得到的只是 500 错误!我什至尝试附加到该进程并闯入我的服务。在 ASP 管道进入我的代码之前就抛出了 500 错误。

更新:通过 WCF 服务工作。这是我的设置:界面:

现在我收到这个错误:IIS 指定了身份验证方案“IntegratedWindowsAuthentication、Anonymous”,但绑定仅支持指定一种身份验证方案。有效的身份验证方案包括摘要、协商、NTLM、基本或匿名。更改 IIS 设置,以便仅使用单一身份验证方案。
我该如何处理这个问题?
