请问为什么会出现OSError: [Errno 22] Invalid argument错误:
demo.py:
html:
<form action="{{ url_for('login') }}" method="post">
<input class="gv" style="cursor: text" type="text" placeholder="学号" name="student_id">
<input class="gv" style="cursor: text" type="password" placeholder="密码" name="password">
<button id="check-btn2" class="gv" type="submit">提交</button>
报错:
app.run()中的debug=True去掉
