SMTP 通知操作指南¶

简介¶

SMTP 通知器 (airflow.providers.smtp.notifications.smtp.SmtpNotifier) 允许用户在 DAG 级别和 Task 级别使用各种 on_*_callbacks 向 SMTP 服务器发送消息。

示例代码:¶

from datetime import datetime
from airflow import DAG
from airflow.providers.standard.operators.bash import BashOperator
from airflow.providers.smtp.notifications.smtp import send_smtp_notification

with DAG(
    dag_id="smtp_notifier",
    schedule=None,
    start_date=datetime(2023, 1, 1),
    catchup=False,
    on_failure_callback=[
        send_smtp_notification(
            from_email="[email protected]",
            to="[email protected]",
            subject="[Error] The dag {{ dag.dag_id }} failed",
            html_content="debug logs",
        )
    ],
):
    BashOperator(
        task_id="mytask",
        on_failure_callback=[
            send_smtp_notification(
                from_email="[email protected]",
                to="[email protected]",
                subject="[Error] The Task {{ ti.task_id }} failed",
                html_content="debug logs",
            )
        ],
        bash_command="fail",
    )
