.net HTTP_X_FORWARDED_FOR在localhost上为NULL [英] .net HTTP_X_FORWARDED_FOR NULL on localhost
问题描述
道歉,如果已经回答了其他地方,我找不到它。
Apologises if this has been answered else where, I could not find it.
如果没有,我试图找到访问该网站的机器的原始IP。
In the case it has not, I am trying to find the original IP of a machine who has accessed the site.
在我的基本理解中,变量 HTTP_X_FORWARDED_FOR
将显示用户的IP,无论代理和其他过滤器如何。如果这是真的,我正在尝试编码,但我得到一个空字符串
In my basic understanding, the variable HTTP_X_FORWARDED_FOR
will display the user's IP regardless of proxy's and other filters. if this is true, I am trying to code this but I get a null string
System.Web.HttpContext context = System.Web.HttpContext.Current;
string ipAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
可能出现的问题 HTTP_X_FORWARDED_FOR
未出现在HTTP HEADERS /服务器变量列表中,还是我使用的是localhost?使用 REMOTE_ADDR
,将显示localhost IP。
Possible problems are HTTP_X_FORWARDED_FOR
doesn't appear in the HTTP HEADERS / server variable list, or I am using localhost? Using REMOTE_ADDR
, the localhost IP is displayed.
我是在正确的位置还是我的理解不正确?
Am I on the right lines or is my understanding incorrect?
谢谢
推荐答案
HTTP_X_FORWARDED_FOR标头通常包含代理值,因此您不会在本地计算机上看到任何内容,因为您没有通过任何代理
HTTP_X_FORWARDED_FOR header usually hold proxy values so it is normal you dont see any content on your local machine since you are not going through any proxies
