Question

我在这里疯了。我查看了以下条目， none 正在纠正我看到的异常行为：

我也看过了，并确认了我的设置：http://www.asp.net/AJAX/documentation/live/ConfiguringASPNETAJAX.aspx

这是我的代码（ASMX代码背后）：

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;
        }
    }

当我从我的localhost实例运行时，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>

我缺少什么？

注意：我正在使用3.5框架（或者至少我认为我的web.config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。你可以在这里试试：http://dev.rivworks.com/services/Negotiate.asmx?op=GetSetup。我们还试图从在另一个站点上运行的基于JS的Web应用程序（此特定服务的主要目的）访问它。我这里没有代码。（对不起，测试表只能从localhost获得。）

更新：我添加了以下测试页面（JsonTest.htm）以尝试查看来回的内容。我得到的只是500错误！我甚至试图加入这个过程并打破我的服务。在ASP管道进入我的代码之前，会抛出500错误。

为什么这么痛苦？！？！：）

更新：通过WCF服务。这是我的设置： 接口：

namespace RivWorks.Web.Services
{
    [ServiceContract(Name = "Negotiater", Namespace = "http://www.rivworks.com/services")]
    public interface INegotiaterJSON
    {
        //[WebMethod]
        [OperationContract]
        [WebInvoke(BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]
        ResultSet GetSetup(string jsonInput);
    }
}

类别：

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    public class Negotiater : INegotiaterJSON

        {
            //code removed for brevity - see ASMX code above if you are really interested.
            return resultSet;
        }
    }

</html>

现在我收到了这个错误： IIS指定的身份验证方案“IntegratedWindowsAuthentication，Anonymous”，但绑定仅支持一种身份验证方案的规范。有效的身份验证方案是Digest，Negotiate，NTLM，Basic或Anonymous。更改IIS设置，以便仅使用单个身份验证方案。

我该如何处理？＆lt; state emotion ='拧干'physical ='beat up'/＆gt;

Answer 1

为什么不将ASMX Web服务迁移到WCF？

.NET Framework 3.5中的WCF API本身支持JSON Web服务。

此外，Microsoft将ASMX称为“遗留技术”，并建议“现在应使用Windows Communication Foundation（WCF）创建Web服务和XML Web服务客户端”。（Source）。

您可以查看这些链接以开始使用：

此外，您可能还想阅读以下我从我自己托管的WCF项目中“提取”的示例。自托管WCF服务不需要IIS，但可以从任何托管的.NET应用程序提供。此示例托管在一个非常简单的 C＃控制台应用程序：

中

<强> IContract.cs

using System;
using System.Collections;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;

namespace MyFirstWCF
{
    [ServiceContract] 
    public interface IContract
    {
        [OperationContract]
        [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "/CustomerName/{CustomerID}")]
        string GET_CustomerName(string CustomerID);
    }
}

<强> Service.cs

using System;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Syndication;
using System.ServiceModel.Web;

namespace MyFirstWCF
{
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.NotAllowed)]
    public class Service : IContract
    {
        public string GET_CustomerName(string CustomerID)
        {
            return "Customer Name: " + CustomerID;
        }
    }
}

WCFHost.cs （控制台应用程序）

using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.ServiceModel.Description;
using System.Threading;
using System.Text;

namespace MyFirstWCF
{
    class Program
    {
        private static WebServiceHost M_HostWeb = null;

        static void Main(string[] args)
        {
            M_HostWeb = new WebServiceHost(typeof(MyFirstWCF.Service));

            M_HostWeb.Open();

            Console.WriteLine("HOST OPEN");
            Console.ReadKey();

            M_HostWeb.Close();
        }
    }
}

<强>的app.config

<?xml version="1.0" encoding="utf-8" ?>

<configuration>
  <system.serviceModel>
    <services>
      <service name="MyFirstWCF.Service">

        <endpoint address="http://127.0.0.1:8000/api"
                  binding="webHttpBinding"
                  contract="MyFirstWCF.IContract" />

      </service>
    </services>

  </system.serviceModel>
</configuration>

以上示例非常基本。如果您使用Fiddler与http://127.0.0.1:8000/api/CustomerName/1000建立请求，则只会返回"Customer Name: 1000"。

确保在请求标头中设置content-type: application/json。要返回更复杂的数据结构，您必须使用数据协定。这些构造如下：

[DataContract]
public class POSITION
{
    [DataMember]
    public int      AssetID { get; set; }

    [DataMember]
    public decimal  Latitude { get; set; }

    [DataMember]
    public decimal  Longitude { get; set; }
}

您需要将System.RuntimeSerialization，System.ServiceModel和System.ServiceModel.Web的.NET引用添加到此示例项目中进行编译。

Answer 2

对方法的请求设置的“内容类型”是什么？

从我对ASP.NET所做的工作来看，如果设置为text/xml，你将获得XML;但如果它设置为application/json，你将获得JSON。

.NET ASMX - 返回纯JSON？
