Django獲取內網ip

1. 創建middleware.py

class InternalIPMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        # 獲取請求頭中的X-Forwarded-For字段
        forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
        if forwarded_for:
            # 以逗號爲分隔符，獲取最後一個IP地址
            internal_ip = forwarded_for.split(',')[-1].strip()
            # 如果獲取到的IP地址是內網IP，則設置到request的內網IP屬性中
            if self.is_internal_ip(internal_ip):
                request.internal_ip = internal_ip
        else:
            request.internal_ip = request.META.get('REMOTE_ADDR')
        return self.get_response(request)

    def is_internal_ip(self, ip):
        # 判斷IP地址是否爲內網IP地址
        internal_ip_ranges = [
            ('10.0.0.0', '10.255.255.255'),
            ('172.16.0.0', '172.31.255.255'),
            ('192.168.0.0', '192.168.255.255'),
        ]
        for start, end in internal_ip_ranges:
            if self.is_in_range(ip, start, end):
                return True
        return False

    def is_in_range(self, ip, start, end):
        # 判斷IP地址是否在指定的IP地址範圍內
        ip_int = self.ip_to_int(ip)
        start_int = self.ip_to_int(start)
        end_int = self.ip_to_int(end)
        return start_int <= ip_int <= end_int

    @staticmethod
    def ip_to_int(ip):
        # 將IP地址轉換爲整數
        parts = [int(part) for part in ip.split('.')]
        return (parts[0] << 24) + (parts[1] << 16) + (parts[2] << 8) + parts[3]

 

2. setting.py註冊中間件

MIDDLEWARE = [
    # ... 其他中間件 ...
    'myapp.middlewares.InternalIPMiddleware',
]

3. 視圖函數捕獲

def my_view(request):
    internal_ip = getattr(request, 'internal_ip', None)
