Question

我正在我们的烧瓶应用程序中实现烧瓶邮件，但无法摆脱应用程序用完的上下文错误。任何帮助，将不胜感激。我已将mail_server params放在配置文件中。

/app.py - app在create_web_apis

中实例化

def create_app(config):
"""Creates an instance of the app according to `config`

:param config: An instance of :class:`flask.config.Config`

:returns: The configured application. This can be passed to a WSGI
  container.

"""
app = create_web_apis()

app.config.update(config)
mail = Mail(app)
...

/emails.py

from flask import current_app
from flask.ext.mail import Mail, Message


mail = Mail(current_app) 

def send_email(subject, sender, recipients, text_body, html_body):
    msg = Message(subject, sender = sender, recipients = recipients)
    msg.body = text_body
    msg.html = html_body
    mail.send(msg)

这里是完整的跟踪

您应该在测试中提供应用程序上下文，例如使用app.test_request_context。您可以在official docs

中阅读更多内容

你可以试试这个：

emails.py

from flask import current_app
from flask.ext.mail import Mail, Message

def send_email(subject, sender, recipients, text_body, html_body):
    mail = Mail(current_app) 
    msg = Message(subject, sender = sender, recipients = recipients)
    msg.body = text_body
    msg.html = html_body
    mail.send(msg)

test.py

import unittest
from app import create_app
from flask.ext.mail import Message
from emails import send_email

class AppTestCase(unittest.TestCase):
    def setUp(self):
       self.app = create_app()

    def test_mail(self):
        with self.app.test_request_context('/'):
            send_email("Hello",
                  sender="from@example.com",
                  recipients=["to@example.com"],
                  text_body='',
                  html_body='',
            )

if __name__ == '__main__':
    unittest.main()

注意：

如果您在Mail中创建app.py个实例，请不要在emails.py中重复。某物如下所示应该足够了：

app.py

from flask import Flask def create_app(): app = Flask(__name__) return app

test.py

import unittest from app import create_app from flask.ext.mail import Message class AppTestCase(unittest.TestCase): def setUp(self): self.app = create_app() def test_mail(self): with self.app.test_request_context('/'): self.app.mail.send(Message("Hello", sender="from@example.com", recipients=["to@example.com"])) if __name__ == '__main__': unittest.main()

您可以使用DebuggingServer
进行测试
python -m smtpd -n -c DebuggingServer localhost:1025
