我在Visual Studio 2008中使用带有C＃的ASP.NET 3.5。 我对WCF很天真。我已经创建了一个示例wcf应用程序，并在Visual Studio中的asp.net开发服务器上运行它。我正在调用GetData（）方法，即在创建应用程序并获得400个错误请求时自动生成。我已经尝试了很多，但结果令人沮丧。
我的界面 IService1.cs 如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Web;
using System.ServiceModel.Activation;
namespace WcfService1
{
// NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(RequestFormat=WebMessageFormat.Json,ResponseFormat=WebMessageFormat.Json,Method="GET",UriTemplate="/getdata/{}")]
string GetData(int value);
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
// TODO: Add your service operations here
}
// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class CompositeType
{
bool boolValue = true;
string stringValue = "Hello ";
[DataMember]
public bool BoolValue
{
get { return boolValue; }
set { boolValue = value; }
}
[DataMember]
public string StringValue
{
get { return stringValue; }
set { stringValue = value; }
}
}
}
Class Service1.svc.cs 文件如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WcfService1
{
// NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in Web.config and in the associated .svc file.
public class Service1 : IService1
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
public CompositeType GetDataUsingDataContract(CompositeType composite)
{
if (composite.BoolValue)
{
composite.StringValue += "Suffix";
}
return composite;
}
}
}
web.config如下：
<?xml version="1.0"?>

有人可以帮忙吗？
答案 0 :(得分：15)
有4个错误：
首先，您应该使用webHttpBinding而不是wsHttpBinding。 wsHttpBinding仅用于SOAP服务 - 不是REST服务。
其次，您需要添加端点行为。
因此，您的端点将如下所示：
<endpoint address="" binding="webHttpBinding" contract="WcfService1.IService1" behaviorConfiguration="webBehavior">
在行为部分你应该
<endpointBehaviors>
<behavior name="webBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
第三，您的URI模板应该是
UriTemplate="/getdata/{value}"
而不是
UriTemplate="/getdata/{}"
最后，您在URI模板中使用的参数必须是string类型，所以
string GetData(string value);
而不是
string GetData(int value);
在服务操作中，您必须将字符串值解析为正确的类型。
总的来说，使用ASP.Net WebAPI而不是WCF REST更容易使用 MUCH 进行REST。如果您可以转移到.Net 4而不是3.5，那么您将获得更快的进展，并且您将使用适当支持的平台。
此外，对于开发，您应该设置
<serviceDebug includeExceptionDetailInFaults="true"/>
因此，您可以获得有关出错的更多信息。请记住将其重新设置为false以进行制作。

我遇到了这个问题，我不完全确定原因，但是当我删除了“工厂”时。属性到我的.SVC文件（你需要将它显式拖到Visual Studio），我得到了我的WSDL。
我删除了 Factory =＆＃34; System.ServiceModel.Activation.WebServiceHostFactory＆＃34; ，所以我的.SVC文件来自：
<%@ ServiceHost Language="C#" Debug="true" Service="ServiceNameSpace.ServiceName" CodeBehind="ServiceName.svc.cs" Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
到此：
<%@ ServiceHost Language="C#" Debug="true" Service="ServiceNameSpace.ServiceName" CodeBehind="ServiceName.svc.cs" %>
