如何检查localhost

Question

在c#中是否有办法检查应用程序是否在localhost上运行(而不是生产服务器)？

我正在编写一个群发邮件程序,需要使用某个邮件队列才能在localhost上运行.

if (Localhost)
{
Queue = QueueLocal;
}
else
{
Queue = QueueProduction;
}

Answer 1

由于评论有正确的解决方案,我将把它作为答案发布:

HttpContext.Current.Request.IsLocal 

Answer 2

怎么样的:

public static bool OnTestingServer()
    {
        string host = HttpContext.Current.Request.Url.Host.ToLower();
        return (host == "localhost");
    }

Answer 3

在应用程序配置文件中使用一个值,该值将告诉您所处的环境.

由于您使用的是asp.net,因此您可以利用配置文件转换来确保每个环境的设置都是正确的.

看看这是否有效:

public static bool IsLocalIpAddress(string host)
{
  try
  { // get host IP addresses
    IPAddress[] hostIPs = Dns.GetHostAddresses(host);
    // get local IP addresses
    IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());

    // test if any host IP equals to any local IP or to localhost
    foreach (IPAddress hostIP in hostIPs)
    {
      // is localhost
      if (IPAddress.IsLoopback(hostIP)) return true;
      // is local address
      foreach (IPAddress localIP in localIPs)
      {
        if (hostIP.Equals(localIP)) return true;
      }
    }
  }
  catch { }
  return false;
}

Answer 5

Localhost IP地址是常量,您可以使用它来确定它是localhost还是远程用户.

但要注意,如果您登录到生产服务器,它也将被视为localhost.

这包括IP v.4和v.6:

public static bool isLocalhost( )
{
    string ip = System.Web.HttpContext.Current.Request.UserHostAddress;
    return (ip == "127.0.0.1" || ip == "::1");
}

要完全确定运行代码的服务器,可以使用MAC地址:

public string GetMACAddress()
{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    String sMacAddress = string.Empty;
    foreach (NetworkInterface adapter in nics)
    {
        if (sMacAddress == String.Empty)// only return MAC Address from first card  
        {
            IPInterfaceProperties properties = adapter.GetIPProperties();
            sMacAddress = adapter.GetPhysicalAddress().ToString();
        }
    } return sMacAddress;
}

例如,与web.config中的MAC地址进行比较.

public static bool isLocalhost( )
{
    return GetMACAddress() == System.Configuration.ConfigurationManager.AppSettings["LocalhostMAC"].ToString();
}

不幸的是HttpContext.HttpRequest.IsLocal()，核心中不再有。

但是在 .Net 中检查了原始实现之后，通过检查重新实现相同的行为是很容易的HttpContext.Connection：

private bool IsLocal(ConnectionInfo connection)
{
    var remoteAddress = connection.RemoteIpAddress.ToString();

    // if unknown, assume not local
    if (String.IsNullOrEmpty(remoteAddress))
        return false;

    // check if localhost
    if (remoteAddress == "127.0.0.1" || remoteAddress == "::1")
        return true;

    // compare with local address
    if (remoteAddress == connection.LocalIpAddress.ToString())
        return true;

    return false;
}
