asp.net-mvc - 从 mvc 的视图中使用 json wcf 服务

Question

我正在尝试将我的“用户”表的所有信息存储在 wcf 中。并以 json 格式返回。当我调用服务时，我可以看到实体。但我的问题是如何在我看来调用此服务。我尝试过使用 ajax 调用它，但所发出的只是错误消息:( 请帮助

服务.svc.cs

namespace jsonwcf
{

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    public class Service1 : IService1
    {
        [WebInvoke(
       Method = "POST",
       ResponseFormat = WebMessageFormat.Json,
       BodyStyle = WebMessageBodyStyle.WrappedRequest
     )]
        public List<UserDetails> SelectUserDetails()
        {
            pasDataContext db = new pasDataContext();
            List<UserDetails> results = new List<UserDetails>();

            foreach (User u in db.Users)
            {
                results.Add(new UserDetails()
                {
                    UserID = u.UserID,

                    EmpName = u.EmpName,
                    Email = u.EmailID,
                    UserName = u.UserName,
                    UserRole = u.UserRole,
                    Password = u.Password,
                    Telephone = u .Telephone
                });
            }
            return results;
        }
    }
}
