我試圖設定硬編碼身份驗證只是為了在我的def login()路線中進行測驗，但forms.user_email.data/forms.user_password.data正在回傳None？我也注意到form在我def home()表現出相同的行為。我相信這是多個問題的根源，但老實說我不確定。我已經閱讀了多篇關于使用 request 的帖子 - 但我一直看到其他人使用 FlaskForm 來實作這一目標？
非常感謝任何指導，以及任何一般的 Flask 提示 - 我對 Python/Flask 很陌生。我一直很難理解flask/flask_restful 的最佳實踐/用例，更不用說所有可能的擴展，如flask_bootstrap、FlaskForm、WTForms、FlaskLogin 等。提前致謝。

uj5u.com熱心網友回復：
在你的login.html而不是：
<form class="form-signin" method="POST" action="{{ url_for('home') }}">
行動應該login代替home。所以它應該是這樣的：
<form class="form-signin" method="POST" action="{{ url_for('login') }}">
