得到的ASP.NET Web API网页API消费者的IP地址和主机名 [英] Get Web Api consumer IP Address and HostName in ASP.NET Web API

问题描述

我主持在ASP.net开发的Web API。我想如果有人打电话给我的API，这样我就可以登录数据库中，以便以后如果我想用C＃拒绝来自特定ID请求。

什么是得到消费者的IP和主机名的最佳做法？

 公共静态字符串GetIP4Address（）
  {
    字符串IP4Address =的String.Empty;    的foreach（ip地址IPA在Dns.GetHostAddresses（Request.ServerVariables [REMOTE_ADDR]。的ToString（））））
    {
      如果（IPA.AddressFamily.ToString（）==网间）
      {
        IP4Address = IPA.ToString（）;
        打破;
      }
    }    如果（IP4Address！=的String.Empty）
    {
      返回IP4Address;
    }    的foreach（ip地址IPA在Dns.GetHostAddresses（Dns.GetHostName（）））
    {
      如果（IPA.AddressFamily.ToString（）==网间）
      {
        IP4Address = IPA.ToString（）;
        打破;
      }
    }    返回IP4Address;
  }
 

解决方案

解析名称听起来像一个坏主意。如果你是从客户机叫什么DNS没有解决？我告诉你，DNS需要永远，然后失败，你必须赶上和记录为未知主机名。

异常

至于申请地址，只是把它

  HttpContext.Current.Request.UserHostAddress
 

I have hosted Web Api developed in ASP.net. I want if someone call my API so I can log in database so later on if I want to reject request from particular id using C#.

What is best practice to get consumer IP and HostName?

public static string GetIP4Address()
  {
    string IP4Address = String.Empty;

    foreach (IPAddress IPA in Dns.GetHostAddresses(Request.ServerVariables["REMOTE_ADDR"].ToString())))
    {
      if (IPA.AddressFamily.ToString() == "InterNetwork")
      {
        IP4Address = IPA.ToString();
        break;
      }
    }

    if (IP4Address != String.Empty)
    {
      return IP4Address;
    }

    foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
    {
      if (IPA.AddressFamily.ToString() == "InterNetwork")
      {
        IP4Address = IPA.ToString();
        break;
      }
    }

    return IP4Address;
  }

解决方案

Resolving names sounds like a bad idea. What if you are called from a client machine that dns doesn't resolve? I tell you, dns takes forever and then fails with an exception you have to catch and log as "unknown host name".

As for request address, just get it with

 HttpContext.Current.Request.UserHostAddress
