通过云功能通过云存储桶更改发送邮件

Question

我试图配置云功能，以便在文件被推送到 GCP 中的一个云存储桶时发送邮件，而不使用第三方工具。我已经查看了此处的概念，并确保我的发件人电子邮件已注册为授权发件人。

https://cloud.google.com/appengine/docs/standard/python/mail/sending-mail-with-mail-api

requirements.txt 添加了以下值：

google-cloud-storage==1.23.0
googleapis-common-protos==1.3.5
google-api-python-client

在需求文件中。但仍然得到同样的错误。

但是，当我尝试使用以下脚本时，结果出现了这个错误：

ModuleNotFoundError: No module named 'google.appengine' .

提前感谢您的建议和帮助。

from google.appengine.api import app_identity
from google.appengine.api import mail
import webapp2


def send_approved_mail(sender_address):
    # [START send_mail]
    mail.send_mail(sender=sender_address,
                   to="Albert Johnson <Albert.Johnson@example.com>",
                   subject="Your account has been approved",
                   body="""Dear Albert:
Your example.com account has been approved.  You can now visit
http://www.example.com/ and sign in using your Google Account to
access new features.
Please let us know if you have any questions.

""")
    # [END send_mail]


class SendMailHandler(webapp2.RequestHandler):
    def get(self):
        send_approved_mail('{}@appspot.gserviceaccount.com'.format(
            app_identity.get_application_id()))
        self.response.content_type = 'text/plain'
        self.response.write('Sent an email to Albert.')


app = webapp2.WSGIApplication([
    ('/send_mail', SendMailHandler),
], debug=True)

Answer 1

您需要与第三方电子邮件服务（例如 Sendgrid）集成，并将您的云函数构建为云函数，例如：

# using SendGrid's Python Library
# https://github.com/sendgrid/sendgrid-python
import os
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail

sg = SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))

def send_mail(data, context):
    message = Mail(
        from_email='from_email@example.com',
        to_emails='to@example.com',
        subject='This is the subject',
        html_content='This is the content'
    )
    response = sg.send(message)
