Django can determine the source of a request by using the attributes of the request object. Here are some commonly used attributes:<\/p>\n

    \n
  1. The request.META.get(‘HTTP_REFERER’) method returns a string containing the source page where the user clicked the link to access the current page. If the user directly visits the current page or enters it through bookmarks, browser history, etc., the value of this property will be an empty string.<\/li>\n
  2. request.get_host(): returns a string containing the hostname of the current request. For example, if the user is accessing http:\/\/example.com\/mypage, the value of this attribute will be example.com.<\/li>\n
  3. request.META.get(‘REMOTE_ADDR’): returns the user’s IP address.<\/li>\n
  4. request.META.get(‘HTTP_USER_AGENT’): Returns a string containing the user’s browser agent.<\/li>\n<\/ol>\n

    Based on the values of these attributes, you can determine the source of access, such as:<\/p>\n

    def my_view(request):\r\n    referer = request.META.get('HTTP_REFERER')\r\n    host = request.get_host()\r\n    remote_addr = request.META.get('REMOTE_ADDR')\r\n    user_agent = request.META.get('HTTP_USER_AGENT')\r\n\r\n    # \u5224\u65ad\u662f\u5426\u4e3a\u76f4\u63a5\u8bbf\u95ee\r\n    if referer == '':\r\n        # \u5904\u7406\u76f4\u63a5\u8bbf\u95ee\u7684\u60c5\u51b5\r\n        pass\r\n\r\n    # \u5224\u65ad\u662f\u5426\u4e3a\u5916\u90e8\u94fe\u63a5\r\n    if 'example.com' not in referer and host != 'example.com':\r\n        # \u5904\u7406\u5916\u90e8\u94fe\u63a5\u7684\u60c5\u51b5\r\n        pass\r\n\r\n    # \u5224\u65ad\u662f\u5426\u4e3a\u7279\u5b9aIP\u5730\u5740\r\n    if remote_addr == '127.0.0.1':\r\n        # \u5904\u7406\u7279\u5b9aIP\u5730\u5740\u7684\u60c5\u51b5\r\n        pass\r\n\r\n    # \u5224\u65ad\u7528\u6237\u7684\u6d4f\u89c8\u5668\u7c7b\u578b\r\n    if 'Mozilla' in user_agent:\r\n        # \u5904\u7406Mozilla\u6d4f\u89c8\u5668\u7684\u60c5\u51b5\r\n        pass\r\n\r\n    # \u5176\u4ed6\u5224\u65ad\u903b\u8f91...\r\n<\/code><\/pre>\n
    Please note that request.META is a dictionary containing all the metadata for the HTTP request. You can refer to the Django official documentation for more information on the request object and the META attribute.<\/p>\n","protected":false},"excerpt":{"rendered":"
