Question

我是不熟悉Flask并开始创建此小型应用程序，我想发送电子邮件，但是当flask导入 init 文件的配置时，出现错误“ ImportError：可以不能导入名称邮件”。我已经读过它与我的应用程序的结构有关，但是我无法容纳它，因此没有问题。谢谢您的帮助

这是我的应用程序的结构：

└── my-project
    ├── app
    │   ├── __init__.py
    │   ├── constants
    │   │   ├── __init__.py
    │   │   ├── constants.py

    │   ├── default.py
    │   
    └── api.py

api.py

import os
from app import app

if __name__ == '__main__':
    app.run(host=os.environ["API_IP"], port=5000, debug=os.environ["API_DEBUG"])

app / __ init __。py

from flask import Flask
from flask_mail import Mail
from app.apiL import blueprint as apiL

# logging.config.fileConfig('config/development-logging.conf')

app = Flask(__name__)
app.config.from_object('config.default')


# app.config.from_pyfile('config.py')
app.register_blueprint(api_v1)
mail = Mail(app)

资源/Mail.py

from app import mail # you can now import the Mail() object
from flask_mail import Message


class EmailSend:

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

执行时出现以下消息：

| Traceback (most recent call last):
api_1  |   File "api.py", line 2, in <module>
api_1  |     from app import app
api_1  |   File "/usr/src/api/app/__init__.py", line 5, in <module>
api_1  |     from app.api_v1 import blueprint as api_v1
api_1  |   File "/usr/src/api/app/api_v1.py", line 4, in <module>
api_1  |     from app.resources.Session import nsLogIn, nsSignUP, nsVerifyEmail
api_1  |   File "/usr/src/api/app/resources/Session.py", line 19, in <module>
api_1  |     from app.resources.Mail import EmailSend
api_1  |   File "/usr/src/api/app/resources/Mail.py", line 1, in <module>
api_1  |     from app import mail  # you can now import the Mail() object
api_1  | ImportError: cannot import name 'mail'

感谢您的帮助。

您可能有循环依赖问题。在resources / Mail.py文件中，尝试在send_email函数内导入邮件模块。

您的资源/Mail.py文件将与此类似：

from flask_mail import Message


class EmailSend:

    def send_email(subject, sender, recipients, text_body):
        from app import mail # you can now import the Mail() object
        msg = Message(subject=subject, sender=sender, recipients=recipients)
        msg.body = text_body
        #msg.html = html_body
        mail.send(msg)

请参阅ImportError: cannot import name mail in Flask和ImportError: cannot import name mail。
