flask中错误使用flask.redirect('/path')导致的框架奇怪错误

我在首页的位置使用了如下代码：

import flask

@page_index.route('/')

def index():

    flask.redirect('/pythoncgi/')

结果站点出现以下错误：

[11/Nov/2019 15:03:01] "GET / HTTP/1.1" 500 -

Traceback (most recent call last):

  File "/usr/local/lib64/python3.6/site-packages/flask/app.py", line 2463, in __call__

    return self.wsgi_app(environ, start_response)

  File "/usr/local/lib64/python3.6/site-packages/flask/app.py", line 2449, in wsgi_app

    response = self.handle_exception(e)

    return self.finalize_request(rv)

    response = self.make_response(rv)

    "The view function did not return a valid response. The"

TypeError: The view function did not return a valid response. The function either returned None or ended without a return statement.

解决方法如下：

@page_index.route('/')

def index():

    return flask.redirect('/pythoncgi/')
