.net core 獲取本地ip及request請求端口

1.獲取ip和端口

string str = (Request.HttpContext.Connection.LocalIpAddress.MapToIPv4().ToString() + ":" + Request.HttpContext.Connection.LocalPort);

輸出str,會得到當前服務器的IP及端口("127.0.0.1:5001")

2.獲取ip

var ip = HttpContext.Request.Headers["X-Forwarded-For"].FirstOrDefault();
if (string.IsNullOrEmpty(ip))
{
    ip = HttpContext.Connection.RemoteIpAddress.ToString();
}
return ip;  "127.0.0.1"
