Smtp 气流：使用emailoperator时无法分配请求的地址错误

任务失败或使用EmailOperator时无法接收电子邮件

大家好

即使添加了发送电子邮件所需的参数，我也无法从邮箱接收电子邮件

下面是我的默认参数的样子--

在这两者之间，我几乎没有什么HttpsOperator任务——它们工作得很好，也很成功，但它们不会发送错误电子邮件（我特意尝试引入一个错误来检查它们是否发送了任何电子邮件）。下面是我的任务示例

t1 = SimpleHttpOperator(
                   task_id='t1',
                   http_conn_id='http_waterfall',
                   endpoint='/update_data',
                   method='POST',
                   headers={"Content-Type":"application/json"},
                                   xcom_push=True,
                                   log_response=True,
                   dag=dag,
)

这是我的EmailOperator任务

t2 = EmailOperator(
              dag=dag,
                  task_id="send_email",
                  to='phonrao@gmail.com',
                          subject='Success',
                      html_content="<h3>Success</h3>" 
)

t2 >> t1

是否有人遇到此问题以及如何解决此问题的建议？

如果您的气流运行在Kubernetes上（由helm chart安装），您应该查看“airflow-worker-0”pod，并确保SMTP_主机或SMTP_用户的环境变量。。。可在配置文件中找到。只需调试，访问airflow worker的容器，然后运行python，然后尝试这些命令以确保其正常工作

import airflow 
airflow.utils.email.send_email('example@gmail.com', 'Airflow TEST HERE', 'This is airflow status success')

通过解析SMTP的环境变量，我也遇到了同样的问题。现在它可以工作了。

您是否已将气流配置为发送电子邮件？您所说的配置到底是什么意思？请详细说明这是my airflow.cfg```[email]email\u backend=airflow.utils.email.send\u email\u smtp[smtp]#如果您希望airflow在重试、失败时发送电子邮件，并且您希望使用airflow.utils.email.send\u email\u smtp功能，如果要使用smtp身份验证#smtp#用户=airflow#smtp#密码=airflow smtp#端口=25 smtp#邮件#发件人=airflow@example.com```你能在你的问题主体中贴出来吗？这给了我一个警告

警告-在config中找不到section/key[smtp/smtp_user]，然后出现一个错误
{{models.py:1788}错误-[Errno 99]无法分配请求的地址
如果是配置问题，您能告诉我还需要做什么吗？可能的重复项将为您提供配置电子邮件所需的一切。顺便问一下，您是否设置了smtp主机？
