Question

在过去的两天中，我一直在研究一个错误，经过所有调试和在黑暗中拍摄之后，它开始使我吃光。

气流似乎不均匀，触发邮件，我将说明如何：

这是我的airflow.cfg设置：

[email]
email_backend = airflow.utils.email.send_email_smtp
SENDGRID_MAIL_FROM=<random-email-id@doesntexist.com>
#SENDGRID_API_KEY=...
[smtp]e
smtp_host = smtp.sendgrid.net
smtp_starttls = True
smtp_ssl = False
# Uncomment and set the user/pass settings if you want to use SMTP AUTH
smtp_user = apikey
smtp_password = ...
smtp_port = 465
smtp_mail_from = <random-email-id@doesntexist.com>

然后，我看到它所引用的文件是utils / email.py，其方法为：send_email_smtp

def send_email(to, subject, html_content, files=None, dryrun=False, cc=None, bcc=None, mime_subtype='mixed'):
    """
    Send email using backend specified in EMAIL_BACKEND.
    """
    path, attr = configuration.get('email', 'EMAIL_BACKEND').rsplit('.', 1)
    module = importlib.import_module(path)
    backend = getattr(module, attr)
    return backend(to, subject, html_content, files=files, dryrun=dryrun, cc=cc, bcc=bcc, mime_subtype=mime_subtype)

def send_email_smtp(to, subject, html_content, files=None, dryrun=False, cc=None, bcc=None, mime_subtype='mixed'):
    """
    Send an email with html content

    >>> send_email('test@example.com', 'foo', '<b>Foo</b> bar', ['/dev/null'], dryrun=True)
    """
    SMTP_MAIL_FROM = configuration.get('smtp', 'SMTP_MAIL_FROM')
    TITU
    to = get_email_address_list(to)
    log.info("!!!!#@Q@$%%%^%!@!@!@!@!@!@!@!@!@!@%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%")
    msg = MIMEMultipart(mime_subtype)
    msg['Subject'] = subject
    msg['From'] = SMTP_MAIL_FROM
    msg['To'] = ", ".join(to)
    recipients = to
    if cc:
        cc = get_email_address_list(cc)
        msg['CC'] = ", ".join(cc)
        recipients = recipients + cc

    if bcc:
        # don't add bcc in header
        bcc = get_email_address_list(bcc)
        recipients = recipients + bcc

    msg['Date'] = formatdate(localtime=True)
    mime_text = MIMEText(html_content, 'html')
    msg.attach(mime_text)

    for fname in files or []:
        basename = os.path.basename(fname)
        with open(fname, "rb") as f:
            part = MIMEApplication(
                f.read(),
                Name=basename
            )
            part['Content-Disposition'] = 'attachment; filename="%s"' % basename
            part['Content-ID'] = '<%s>' % basename
            msg.attach(part)
    #send_MIME_email(SMTP_MAIL_FROM, recipients, msg, dryrun)
    send_MIME_email_sendgrid(SMTP_MAIL_FROM, recipients, msg, dryrun)

def send_MIME_email_sendgrid(e_from, e_to, mime_msg, dryrun=False):
    log = LoggingMixin().log
    sg = SendGridAPIClient('..<my-sendgrid-key>..')
    sg.send(mime_msg)
    log.info("Sent an alert email to %s", e_to)

即使'log.info（'！＃！@ $＃@％@％'）也没有在上面记录。

请帮助。真的无法正确解决此问题-我正在使用Airflow 1.9.0，并在其顶部安装了sendgrid-默认情况下，Airflow 1.10.0及以下版本不带有sendgrid依赖项

Answer 1

这确实被称为。我们需要两个方面：

将任务指定为：

email_on_failure=True,
email=['i.wont@tell.com']

我们的问题在于与sendgrid进行身份验证，该服务用户从中运行气流Web服务器/调度程序。

未呼叫气流电子邮件后端
