我在settings.py
中有以下代码:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'filters': {
'require_debug_true': { '()': 'django.utils.log.RequireDebugTrue', },
},
'handlers': {
'console': {
'filters': ['require_debug_true'],
'class': 'logging.StreamHandler',
},
'kodular': {
'level': 'WARNING',
'class': 'account.reporter.KodularExceptionHandler',
},
},
'loggers': {
'django': {
'handlers': ['console', 'kodular'],
'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
},
},
}
KodularExceptionHandler
类如下所示:
from copy import copy
import json
import logging
import requests
from django.conf import settings
from django.utils.log import AdminEmailHandler
from django.views.debug import ExceptionReporter
class KodularExceptionHandler(AdminEmailHandler):
def emit(self, record, *args, **kwargs):
print("Triggered")
try:
request = record.request
subject = record.getMessage()
except Exception:
return
if record.exc_info:
exc_info = record.exc_info
else:
exc_info = (None, record.getMessage(), None)
reporter = ExceptionReporter(request, is_email=True, *exc_info)
message = "%s\n\n%s" % (self.format(copy(record)), reporter.get_traceback_text())
text = "**Error Level**: *%s* | **Status Code**: `%s`\n\n\n" % (record.levelname, record.status_code)
url = 'https://api.github.com/repos/'+settings.GITHUB_ORG+'/'+settings.GITHUB_REPO+'/issues'
session = requests.Session()
session.auth = (settings.GITHUB_USERNAME, settings.GITHUB_PASSWORD)
issue = {'title': subject,
'body': text+message.replace('*', '\*').replace('_', '\_'),
'labels': ["error"]}
r = session.post(url, json.dumps(issue))
if r.status_code != 201:
return
github_issue_url = json.loads(r.content)['html_url']
if record.levelname == "WARNING":
return
attachments = [{
'title': subject,
'color': 'danger',
'actions': [{
'type': 'button',
'text': 'Github Issue',
'url': github_issue_url,
'style': 'primary',
}],
'fields': [{
"title": "Level",
"value": record.levelname,
"short": True
},{
"title": "Method",
"value": request.method if request else 'No Request',
"short": True
},{
"title": "Path",
"value": request.path if request else 'No Request',
"short": True
},{
"title": "User",
"value": ( (request.user.username + ' (' + str(request.user.pk) + ')'
if request.user.is_authenticated else 'Anonymous' )
if request else 'No Request' ),
"short": True
},{
"title": "Status Code",
"value": record.status_code,
"short": True
},{
"title": "UA",
"value": ( request.META['HTTP_USER_AGENT']
if request and request.META else 'No Request' ),
"short": False
},{
"title": 'GET Params',
"value": json.dumps(request.GET) if request else 'No Request',
"short": False
},{
"title": "POST Data",
"value": json.dumps(request.POST) if request else 'No Request',
"short": False
}]
}]
data = { 'payload': json.dumps({'attachments': attachments}) }
webhook_url = settings.SLACK_HOOK
r = requests.post(webhook_url, data=data)
当我在设置中设置DEBUG = True
时,一切正常:控制台处理错误(并打印“ Reached”),创建Github问题,并发送Slack通知。
但是,如果我设置DEBUG = False
,则会出错。可以想象,控制台输出的信息更少;但既不会创建Github问题,也不会发送Slack通知。
我认为记录器处理程序中某个地方存在问题。看来KodularExceptionHandler
没有被触发,因为控制台不会打印“ Reached”,而在启用调试时会触发。
您知道是什么原因导致将debug设置为false时无法触发自定义错误报告类吗?
答案 0 :(得分:1)
之所以发生这种情况,是因为这是AdminEmailHandler
(它是KodularExceptionHandler
类的父类)的默认行为(在配置中定义)。由于django应用正在加载(https://github.com/django/django/blob/stable/2.2.x/django/utils/log.py#L49)时AdminEmailHandler
类已启用django.utils.log.RequireDebugFalse
过滤器,因此该过滤器扩展到从处理程序继承的任何类。
您可以使用设置'disable_existing_loggers': True
,也可以完全不继承自AdminEmailHandler
。如果查看AdminEmailHandler
(https://github.com/django/django/blob/stable/2.2.x/django/utils/log.py#L79)的代码,您会注意到您已覆盖其大部分代码(__init__
除外)。也许您可以改为从logging.Handler
继承。

我的urls.py
文件中有一个小问题。我正在使用自定义错误页面处理程序:
from account import views
handler404 = views.error404
handler500 = views.error500
但是,文件views.py
如下所示:
from django.shortcuts import render
from account.admin import requires_login
def error404(request, *args, **kwargs):
return render(request, 'error/404.html')
def error500(request, *args, **kwargs):
return render(request, 'error/500.html')
我将所有内容更改为
from django.shortcuts import render
from account.admin import requires_login
def error404(request, *args, **kwargs):
return render(request, 'error/404.html', status=404)
def error500(request, *args, **kwargs):
return render(request, 'error/500.html', status=500)
