Question

我为我的REST项目使用WCF Rest 40（CS）模板通过URL传递数据时没有遇到任何问题：

http://localhost:8525/Device/Login?deviceID=testid&password=a&serialNum=testserial

但是当传递Json数据时，我得到：

方法不允许
（使用Fiddler回复）

在辅助服务中：

namespace WCFRest.Rest
{
    [ServiceContract]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class DeviceComponent
    {
        [WebInvoke(UriTemplate = "Login?deviceID={deviceID}&password={password}&serialNum={serialNum}", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        public WRModel.Entities.Session Login(string deviceID, string password, string serialNum)
        {
            string ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
            WRModel.Interfaces.IDeviceComponent svc = WRModel.Logic.ConfigAndResourceComponent.Containers().Resolve<WRModel.Interfaces.IDeviceComponent>();
            return svc.Login(deviceID, password, serialNum, ip);
        }

        [WebInvoke(UriTemplate = "Logout", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        public bool Logout(WRModel.Entities.DeviceSession deviceSession)
        {
            WRModel.Interfaces.IDeviceComponent svc = WRModel.Logic.ConfigAndResourceComponent.Containers().Resolve<WRModel.Interfaces.IDeviceComponent>();
            return svc.Logout(deviceSession);
        }
    }
}

登录部分正常，但注销会导致错误。我哪里做错了？感谢帮助。这里有一些使用fiddler的图片：

DeviceSession实体

[DataContract(Name = "DeviceSession", Namespace = "http://MySite.com/1.0/DeviceSession")]
public class DeviceSession : IDeviceSession
{
public DeviceSession()
{
}

public DeviceSession(string session, string loginID, string serial)
{
    Session = session;
    LoginID = loginID;
    Serial = serial;
}

string _session;

[DataMember(Order = 0)]
public string Session
{
    get { return _session; }
    set { _session = value; }
}

string _LoginID;

[DataMember(Order = 1)]
public string LoginID
{
    get { return _LoginID; }
    set { _LoginID = value; }
}

string _serial;

[DataMember(Order = 2)]
public string Serial
{
    get { return _serial; }
    set { _serial = value; }
}

}

在每个示例中，您实际上做了一些不同的事情。在第一个示例（登录）中，您将在网址上发布变量，在您正在帖子中发布的第二个变量中。

需要注意的是，您需要在第二个示例中发布的JSON是字符串的json，而不是包含字符串的对象的json。这意味着json对类型字符串无效。

我建议将它包装在一个对象中，或者像在第一个例子中那样在查询字符串上调用它。

例如，您可以使用

 [WebInvoke(UriTemplate = "Login", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
 public WRModel.Entities.Session Login(LoginDetails details)

登录详细信息是包含deviceId密码serialNumber

的类

如何在WCF Rest中传递Json对象？
