Python 部署在 Elastic Beanstalk 上的 Flask 服务器出现 AWS 内部服务错误，日志显示 SECRET_KEY 从未设置？

Question

我正在尝试使用 Elastic Beanstalk 将我的 Flask 应用程序部署到 AWS。我的应用程序在本地主机上运行完美，但我的应用程序在部署时遇到了问题。我不断收到内部服务错误，当我检查 AWS 上的日志时，他们一直说我的 secret_key 从未设置。以下是来自 AWS 的日志：

Set the secret_key on the application to something unique and secret.

我已经研究了为什么它可以在本地主机上运行而不是在生产环境中运行，之前我在“if name ==”中设置了 application.secret_key main':" 块，而 Elastic Beanstalk 运行我的应用程序的方式会跳过该块。我的目录结构如下所示：

application/
    __init__.py
static/
templates/
application.py
dbhelpers.py
rankgraph.py
scoring_algorithm.py
config.py

我更改了设置密钥的位置，并且尝试了两种不同的方法。这是我设置密钥的地方。

from tinydb import TinyDB
from flask import Flask, render_template, redirect, url_for, request, flash, make_response, session
import os, time, dbhelpers, rankgraph, scoring_algorithm, config

application = app = Flask(__name__)
application.debug = True
application.secret_key = 'asfwoewb09bew'
print(application.config)
db = TinyDB('db.json')

我也在这里设置它，因为第一种方法对我来说仍然没有用，这是我的 init.py.

from flask import Flask


application = Flask(__name__)
application.config.from_object('config')

这是我的 config.py

SECRET_KEY = 'dsaf0897sfdg45sfdgfdsaqzdf98sdf0a'

这里还有 link 到存储库，以防我没有提供足够的信息。 https://github.com/human37/swmac_flask_project

根据评论。

问题的原因尚未确定。

但是，在 Microsoft Azure 上部署相同的应用程序时找到了解决方案。
