Flask RuntimeError:会话不可用，因为使用Flask-Session时未设置密钥

Question

由于此错误，我的heroku应用程序不允许我注册

RuntimeError: The session is unavailable because no secret key was set.  Set the secret_key on the application to something unique and secret.

但是，我将会话密钥设置得很好，

run.py

from app import app, db, manager, sess
import os

app.config['SESSION_TYPE'] = 'filesystem'
app.config['SECRET_KEY'] = 'reds209ndsldssdsljdsldsdsljdsldksdksdsdfsfsfsfis'
sess.init_app(app)
app.secret_key()
if __name__ == "__main__":
    app.debug = True;
    app.run()
    # manager.run()

__init__.py

from flask import Flask 
from flask_session import Session

app = Flask(__name__)
sess = Session()
sess.init_app(app)

app.config['SESSION_TYPE'] = 'memcached'
app.config['SECRET_KEY'] = 'redsfsfsfsfis'

from app import views, db

我已经看过secret key not set in flask session了，但它没有解决我的问题。

Answer 1

多亏了戴维主义我弄明白了，

我不得不把

sess.init_app(app)

之后

app.config['SECRET_KEY'] = 'redsfsfsfsfis'
