Django 요청한 IP 주소 가져오기

django 공식 문서에 리퀘스트가 있습니다.META의 설명:
HttpRequest.META A standard Python dictionary containing all available HTTP headers. Available headers depend on the client and server, but here are some examples: •CONTENT_LENGTH – The length of the request body (as a string). •CONTENT_TYPE – The MIME type of the request body. •HTTP_ACCEPT – Acceptable content types for the response. •HTTP_ACCEPT_ENCODING – Acceptable encodings for the response. •HTTP_ACCEPT_LANGUAGE – Acceptable languages for the response. •HTTP_HOST – The HTTP Host header sent by the client. •HTTP_REFERER – The referring page, if any. •HTTP_USER_AGENT – The client’s user-agent string. •QUERY_STRING – The query string, as a single (unparsed) string. •REMOTE_ADDR – The IP address of the client. •REMOTE_HOST – The hostname of the client. •REMOTE_USER – The user authenticated by the Web server, if any. •REQUEST_METHOD – A string such as “GET” or “POST”. •SERVER_NAME – The hostname of the server. •SERVER_PORT – The port of the server (as a string). With the exception of CONTENT_LENGTH and CONTENT_TYPE, as given above, any HTTP headers in the request are converted to META keys by converting all characters to uppercase, replacing any hyphens with underscores and adding an HTTP_ prefix to the name. So, for example, a header called X-Bender would be mapped to the META key HTTP_X_BENDER. Note that runserver strips all headers with underscores in the name, so you won’t see them in META. This prevents header-spoofing based on ambiguity between underscores and dashes both being normalizing to under- scores in WSGI environment variables. It matches the behavior of Web servers like Nginx and Apache 2.4+.
META 정보를 보려면 다음과 같이 하십시오.

request_meta = request.META
info = []
for k, v in request_meta.items():
    info.append(k)
print(info)

일반적으로 요청할 때마다 IP가 포함되어 있기 때문에 다음과 같은 방법으로 사용자의 실제 IP를 얻을 수 있습니다.

# X-Forwarded-For:  XFF ，      ，   HTTP       IP，      HTTP                   。
def get_ip(request):
    '''      IP  '''
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')  #         
    if x_forwarded_for:
        ip = x_forwarded_for.split(',')[0]  #          ip
    else:
        ip = request.META.get('REMOTE_ADDR')  #        IP
    return ip
