在Django中實(shí)現(xiàn)MySQL數(shù)據(jù)庫(kù)審計(jì)功能,可以通過以下幾個(gè)步驟來完成:
確保已經(jīng)安裝了Django和MySQL連接器。如果沒有安裝,可以使用以下命令進(jìn)行安裝:
pip install django
pip install mysql-connector-python
在Django項(xiàng)目的settings.py
文件中,配置MySQL數(shù)據(jù)庫(kù)連接信息:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'your_database_name',
'USER': 'your_database_user',
'PASSWORD': 'your_database_password',
'HOST': 'localhost',
'PORT': '3306',
}
}
在Django應(yīng)用的models.py
文件中,創(chuàng)建一個(gè)審計(jì)日志模型,用于存儲(chǔ)審計(jì)信息:
from django.db import models
from django.utils import timezone
class AuditLog(models.Model):
ACTION_CHOICES = (
('CREATE', 'Create'),
('UPDATE', 'Update'),
('DELETE', 'Delete'),
)
user = models.CharField(max_length=100)
action = models.CharField(max_length=10, choices=ACTION_CHOICES)
table_name = models.CharField(max_length=100)
record_id = models.IntegerField()
timestamp = models.DateTimeField(default=timezone.now)
def __str__(self):
return f"{self.user} {self.action} on {self.table_name} (ID: {self.record_id})"
在Django項(xiàng)目的middleware.py
文件中,創(chuàng)建一個(gè)中間件用于攔截?cái)?shù)據(jù)庫(kù)操作并記錄審計(jì)日志:
import logging
from django.db import connection
from .models import AuditLog
logger = logging.getLogger(__name__)
class AuditMiddleware:
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
response = self.get_response(request)
return response
def process_response(self, request, response):
if connection.use_debug_cursor:
with connection.cursor() as cursor:
for sql, params in connection.queries:
if sql.strip().lower().startswith("select"):
continue
audit_log = AuditLog(
user=request.user.username if request.user.is_authenticated else 'Anonymous',
action=sql.split()[0].upper(),
table_name=params[0] if params else '',
record_id=params[-1] if len(params) > 0 and isinstance(params[-1], int) else 0,
)
audit_log.save()
return response
在Django項(xiàng)目的settings.py
文件中,將剛剛創(chuàng)建的中間件添加到MIDDLEWARE
列表中:
MIDDLEWARE = [
# ...
'your_project_name.middleware.AuditMiddleware',
]
現(xiàn)在,每當(dāng)執(zhí)行數(shù)據(jù)庫(kù)操作時(shí),Django都會(huì)自動(dòng)記錄審計(jì)日志。請(qǐng)注意,這個(gè)示例僅適用于簡(jiǎn)單的數(shù)據(jù)庫(kù)操作,對(duì)于復(fù)雜的查詢和事務(wù),可能需要進(jìn)一步定制審計(jì)日志模型和中間件。
