如何在c#中为wcf服务中的登录页创建Get和Post方法

[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
    string Login(string username, string password);

    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
    string LoginPost(LoginData loginData);
}

[DataContract]
public class LoginData
{
    [DataMember]
    public string Username { get; set; }

    [DataMember]
    public string Password { get; set; }
}

public class Service : IService
{
    public string Login(string username, string password)
    {
        // 处理登录逻辑
        return "Login successful";
    }

    public string LoginPost(LoginData loginData)
    {
        // 处理登录逻辑
        return "Login successful";
    }
}
