使用 Flask 会话时出现内部服务器错误 [英] Internal Server Error when using Flask session

问题描述

我想在请求之间保存一个 ID，使用 Flask session cookie，但是当我执行请求时，我收到了 Internal Server Error 结果.

I want to save an ID between requests, using Flask session cookie, but I'm getting an Internal Server Error as result, when I perform a request.

我设计了一个简单的 Flask 应用程序来演示我的问题:

I prototyped a simple Flask app for demonstrating my problem:

#!/usr/bin/env python

from flask import Flask, session

app = Flask(__name__)

@app.route('/')
def run():
    session['tmp'] = 43
    return '43'

if __name__ == '__main__':
    app.run()

为什么我在执行请求时无法使用以下值存储 session cookie?

Why I can't store the session cookie with the following value when I perform the request?

推荐答案

根据 Flask 会话文档:

...这意味着用户可以查看您的内容cookie 但不能修改它，除非他们知道用于签字.

... What this means is that the user could look at the contents of your cookie but not modify it, unless they know the secret key used for signing.

为了使用会话，您必须设置密钥.

设置密钥.你应该返回字符串，而不是整数.

Set secret key. And you should return string, not int.

#!/usr/bin/env python

from flask import Flask, session

app = Flask(__name__)

@app.route('/')
def run():
    session['tmp'] = 43
    return '43'

if __name__ == '__main__':
    app.secret_key = 'A0Zr98j/3yX R~XHH!jmN]LWX/,?RT'
    app.run()
