Question

Django 1.4 + python2.7

我的网站有三个域名，例如india.abc.com，usa.abc.com和intl.abc.com。现在我想要的是基于IP地址重定向的域。假设用户属于印度（IP地址）他/她应该转到india.abc.com，如果用户在美国他/她应该转到usa.abc.com。

请指教。这样做的最佳方式是什么？

首先，您需要IP到LOCATION服务才能获得IP的相应位置。无论何时您拥有该服务（或基于数据库的查找算法），您都可以这样做：

# got from here: http://stackoverflow.com/questions/4581789/how-do-i-get-user-ip-address-in-django
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

def get_ip_location(ip):
    # here you need to invoke a IP to location service, or implement your own.
    # It's not that hard. Start here: http://stackoverflow.com/questions/4179000/best-way-to-detect-country-location-of-visitor
    pass

def index(request):
    ip = get_client_ip(request)
    location = get_ip_location(ip)
    if location == 'usa':
        return redirect('http://usa.abc.com')
    elif location == 'japan':
        return redirect('http://jpn.abc.com')
    # you get the idea
    else:
        return redirect('http://global.abc.com')

I.P.基于重定向相同网站的不同域名
