Django：向日志中添加访问者的源IP地址信息

1、在项目中添加：Log.py

# 自定义中间件
import json
import threading
import logging
import socket

try:
    from django.utils.deprecation import MiddlewareMixin
except ImportError:
    MiddlewareMixin = object
local = threading.local()


class RequestLogFilter(logging.Filter):
    """
    日志过滤器，将当前请求线程的request信息保存到日志的record上下文
    record带有formater需要的信息。
    """

    def filter(self, record):
        record.hostname = getattr(local, 'hostname', None)  # 主机名称
        record.dest_ip = getattr(local, 'dest_ip', None)  # 服务器IP
        record.username = getattr(local, 'username', None)  # 用户
        record.source_ip = getattr(local, 'source_ip', None)  # 客户端IP
        record.request_path = getattr(local, 'request_path', None)
        record.request_params = getattr(local, 'request_params', None)

        return True


class RequestLogMiddleware(MiddlewareMixin):
    """
    将request的信息记录在当前的请求线程上。
    """

    def process_request(self, request):
        local.hostname = socket.gethostname()
        local.dest_ip = socket.gethostbyname(local.hostname)
        local.username = request.user
        x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR', '')
        if x_forwarded_for:
            source_ip = x_forwarded_for.split(',')[0]  # 所以这里是真实的ip
        else:
            source_ip = request.META.get('REMOTE_ADDR')  # 这里获得代理ip
        local.source_ip = source_ip
        local.request_path = request.path
        local.request_params = json.dumps(request.POST)

    def process_response(self, request, response):
        return response

2、修改项目的settings.py

# 日志文件配置
LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,    # 是否禁用已经存在的日志器
    'formatters': {                      # 日志信息显示的格式
        'verbose': {'format': '[%(asctime)s %(levelname)s [%(module)s:%(lineno)d] [%(process)d:%(threadName)s] %(message)s'},
        'simple':  {'format': '%(asctime)s %(levelname)s [%(module)s:%(lineno)d] %(message)s'},
        'complex': {'format': '[%(hostname)s source_ip:%(source_ip)s] [%(asctime)s %(levelname)s [%(module)s:%(lineno)d] [%(process)d:%(threadName)s] %(message)s'},
    },
    'filters': {
        'new_add': {
            '()': 'ironfort.Log.RequestLogFilter',
        },
    },
    'handlers': {          # 日志处理方法
        'console': {      # 向终端中输出日志
            'level': 'INFO',
            'filters': ['new_add'],
            'class': 'logging.StreamHandler',
            'formatter': 'complex'
        },
    },
    'loggers': {
        'django': {      # 定义了一个名为django的日志器
            'handlers': ['console'],              # 可以同时向终端与文件中输出日志
            'level': 'INFO',                      # 日志器接收的最低日志级别
            'propagate': False,                   # 是否继承父类的log信息，0:否 1:是
        },
    }
}
