小编tbo*_*ins的帖子

我是web api的新手,我似乎遇到了在post方法中获取已登录用户名的问题.我正在使用

RequestContext.Principal.Identity.Name

但是,这似乎只是返回一个空字符串.它在我的get方法中工作正常,但不在帖子中.这是我的整个方法

[Route("receive")]
        [HttpPost]
        public HttpResponseMessage Receive(PostmarkInboundMessage message)
        {
            if (message != null)
            {
                // To access message data
                var headers = message.Headers ?? new List<Header>();

                // To access Attachments
                if (message.Attachments != null)
                {
                    var attachments = message.Attachments;

                    var c = new CVService();
                    var user = string.IsNullOrEmpty(RequestContext.Principal.Identity.Name) ? "unknown" : RequestContext.Principal.Identity.Name;

                    c.UpdateLog(user);

                    foreach (var attachment in attachments)
                    {
                        // Access normal members, etc
                        var attachmentName = attachment.Name;

                        // To access file data and save to c:\temp\
                        //if …

我只是想知道当我注册它时是否可以调用我的服务中的方法。

public interface IDataService
{
   User GetUserById(int id);
   void SaveUser(int id, User user);
}

public class DataService : IDataService
{
    public User GetUserById(int id) 
    { 
       // do stuff 
    };

    public void SaveUser(int id, User user) 
    { 
       // do stuff 
    };

    public void InitialiseService() { };
}

当我注册此组件时，是否可以调用 InitialiseService 来初始化我的服务？

builder.RegisterType<DataService>()
                    .Keyed<IDataService>(FiberModule.Key_DoNotSerialize)
                    .AsImplementedInterfaces()
                    .SingleInstance();
