RuntimeError:在应用程序上下文之外工作。
这通常意味着您尝试使用所需的功能 以某种方式与当前应用程序对象交互。解决 为此,使用app.app_context()设置应用程序上下文。见 文档以获取更多信息。
我以为我已经创建了app_context,但是代码仍然显示运行时错误。请帮忙,谢谢。
答案 0 :(得分:0)
app = current_app._get_current_object()
with app.app_context():
pass
# send email here
或
from main import app
with app.app_context():
pass
# main.py
app = Flask(__name__)
_get_current_object():
返回当前对象。如果出于性能原因一次希望将真实对象放在代理后面,或者因为要将对象传递到不同的上下文,这将很有用。
current_app是Flask代理对象:
current_app = LocalProxy(_find_app)
您只能在当前线程中从current_app获取应用对象
