簡單記錄一下，或許有時後會出現一些奇怪的東西也說不定

像是它會跑出::1 這種結果，還需要深入研究才知道

 

 

使用HTTP_X_FORWARDED_FOR

HttpContext context = HttpContext.Current;
if (context == null)
{
    return string.Empty;
}

HttpRequest request = context.Request;
if (request == null)
{
    return string.Empty;
}

return request.ServerVariables["HTTP_X_FORWARDED_FOR"];

 

使用REMOTE_ADDR

HttpContext context = HttpContext.Current;
if (context == null)
{
    return string.Empty;
}

HttpRequest request = context.Request;
if (request == null)
{
    return string.Empty;
}

return request.ServerVariables["REMOTE_ADDR"];

 

使用UserHostAddress

HttpContext context = HttpContext.Current;
if (context == null)
{
    return string.Empty;
}

HttpRequest request = context.Request;
if (request == null)
{
    return string.Empty;
}

return request.UserHostAddress;
