我有一個RegisterForm和LoginForm與瓶制成，與SHA256散列。的RegisterForm作業，但在登錄頁面不回傳任何東西。我留在同一個登錄頁面，唯一的區別是 url 回傳這個：
HTTP/1.1[0m" 304 -INFO:werkzeug:127.0.0.1 - - [27/Nov/2021 04:56:29]
"GET /?username=alex29&password=12345&submit=Login HTTP/1.1" 200 -
網址更改為：
http://localhost:5000/?username=alex29&password=12345&submit=Login
