捕获celery task异常的两种方式, sentry, mail

sentry (sentry 记录异常.)

import sentry_sdk
 
from sentry_sdk.integrations.celery import CeleryIntegration
 
 
sentry_sdk.init(
    dsn="", # dsn地址.
    integrations=[CeleryIntegration()],
 
    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for performance monitoring.
    # We recommend adjusting this value in production,
    traces_sample_rate=1.0,
)

mail (捕获异常, 发送邮件.)

import smtplib
import traceback
 
from email.header import Header
from email.mime.text import MIMEText
 
 
# 第三方 SMTP 服务
mail_host = ""  # 设置服务器
mail_user = ""  # 用户名
mail_pass = ""  # 密码
 
sender = ""
receivers = [""]  # 接收邮件, 设置邮箱
 
 
def celery_exception_decorator(task):
 
    def decorator(*args, **kwargs):
        try:
            task(*args, **kwargs)
        except Exception:
            celery_exception_trace_info(task.__name__, str(traceback.format_exc()))
 
    return decorator
 
 
def celery_exception_trace_info(name, info):
    message = MIMEText('{}: {}'.format(name, info), 'plain', 'utf-8')
    message['From'] = Header("CJ 运维组", 'utf-8')
    message['To'] = Header("CJ 开发组", 'utf-8')
 
    subject = 'celery 任务异常'
    message['Subject'] = Header(subject, 'utf-8')
 
    try:
        smtp_obj = smtplib.SMTP()
        smtp_obj.connect(mail_host, 25)  # 25 为 SMTP 端口号
        smtp_obj.login(mail_user, mail_pass)
        smtp_obj.sendmail(sender, receivers, message.as_string())
        print("邮件发送成功")
    except smtplib.SMTPException:
        print("Error: 无法发送邮件")
