如何在Django中获取用户的IP ?

我的观点是这样的:

# Create your views
from django.contrib.gis.utils import GeoIP
from django.template import  RequestContext
from django.shortcuts import render_to_response

def home(request):
  g = GeoIP()
  client_ip = request.META['REMOTE_ADDR']
  lat,long = g.lat_lon(client_ip)
  return render_to_response('home_page_tmp.html',locals())

但是我得到了这个错误:

KeyError at /mypage/
    'REMOTE_ADDR'
    Request Method: GET
    Request URL:    http://mywebsite.example/mypage/
    Django Version: 1.2.4
    Exception Type: KeyError
    Exception Value:
    'REMOTE_ADDR'
    Exception Location: /mysite/homepage/views.py in home, line 9
    Python Executable:  /usr/bin/python
    Python Version: 2.6.6
    Python Path:    ['/mysite', '/usr/local/lib/python2.6/dist-packages/flup-1.0.2-py2.6.egg', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/local/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages', '/usr/lib/pymodules/python2.6']

最简单的解决方案(如果你正在使用fastcgi+nignx)是itgorilla评论的:

谢谢你这个好问题。我的fastcgi没有传递REMOTE_ADDR元键。我在nginx.conf中添加了下面的行,并修复了这个问题:——itgorilla

Ps:我添加这个答案只是为了让他的解决方案更明显。

其他回答

def get_client_ip(request):
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        ip = x_forwarded_for.split(',')[0]
    else:
        ip = request.META.get('REMOTE_ADDR')
    return ip

确保你有反向代理(如果有)配置正确(例如mod_rpaf安装Apache)。

注意:上面使用X-Forwarded-For中的第一项,但你可能想使用最后一项(例如,在Heroku的情况下:在Heroku上获取客户端的真实IP地址)

然后把请求作为参数传递给它;

get_client_ip(request)

Django文档HttpRequest。元

django。版本 (2,1,1, 'final', 0) 请求处理程序

sock=request._stream.stream.raw._sock
#<socket.socket fd=1236, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('192.168.1.111', 8000), raddr=('192.168.1.111', 64725)>
client_ip,port=sock.getpeername()

如果你调用以上代码两次,你可能会得到

AttributeError(“_io。BytesIO的对象没有属性“stream”

AttributeError("'LimitedStream'对象没有'raw'属性")

你可以使用django-ipware,它支持Python 2和3,并处理IPv4和IPv6。

安装:

PIP安装django-ipware

简单的用法:

# In a view or a middleware where the `request` object is available

from ipware import get_client_ip
ip, is_routable = get_client_ip(request)
if ip is None:
    # Unable to get the client's IP address
else:
    # We got the client's IP address
    if is_routable:
        # The client's IP address is publicly routable on the Internet
    else:
        # The client's IP address is private

# Order of precedence is (Public, Private, Loopback, None)

先进的用法:

Custom Header - Custom request header for ipware to look at: i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR']) i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR', 'REMOTE_ADDR']) Proxy Count - Django server is behind a fixed number of proxies: i, r = get_client_ip(request, proxy_count=1) Trusted Proxies - Django server is behind one or more known & trusted proxies: i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2')) # For multiple proxies, simply add them to the list i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2', '177.3.3.3')) # For proxies with fixed sub-domain and dynamic IP addresses, use partial pattern i, r = get_client_ip(request, proxy_trusted_ips=('177.2.', '177.3.'))

注:阅读本通知。

在我的情况下,以上都不行,所以我必须检查uwsgi + django源代码,并在nginx中传递静态参数,看看为什么/如何,下面是我发现的。

Env信息: Python版本:2.7.5 Django版本:(1,6,6,'final', 0) Nginx版本:Nginx /1.6.0 uwsgi: 2.0.7

环境设置信息: Nginx作为反向代理监听端口80 Uwsgi作为上游Unix套接字,将最终响应请求

Django配置信息:

USE_X_FORWARDED_HOST = True # with or without this line does not matter

nginx配置:

uwsgi_param      X-Real-IP              $remote_addr;
// uwsgi_param   X-Forwarded-For        $proxy_add_x_forwarded_for;
// uwsgi_param   HTTP_X_FORWARDED_FOR   $proxy_add_x_forwarded_for;

// hardcode for testing
uwsgi_param      X-Forwarded-For        "10.10.10.10";
uwsgi_param      HTTP_X_FORWARDED_FOR   "20.20.20.20";

获取django应用程序中的所有参数:

X-Forwarded-For :       10.10.10.10
HTTP_X_FORWARDED_FOR :  20.20.20.20

结论:

所以基本上,你必须在nginx中指定完全相同的字段/参数名,并使用request。django应用程序中的META[字段/参数]

现在你可以决定是添加一个中间件(拦截器),还是在某些视图中解析HTTP_X_FORWARDED_FOR。

下面是一个简短的一行代码来完成这个任务:

request.META.get('HTTP_X_FORWARDED_FOR', request.META.get('REMOTE_ADDR', '')).split(',')[0].strip()
