创建 templates 文件夹，在该文件夹下创建 register.html 文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>欢迎注册用户</h1>
<form action="/register" method="post">
<p><input type="text" name="username" placeholder="用户名"></p>
<p><input type="password" name="password" placeholder="密码"></p>
<p><input type="password" name="repassword" placeholder="确认密码"></p>
<p><input type="submit" value="注册"></p>
</form>
</body>
</html>
在 app.py 下添加
@app.route(\'/register\', methods=[\'GET\', \'POST\'])
def register():
if request.method == \'POST\':
print(request.form.get(\'username\'))
print(request.form.get(\'password\'))
print(request.form.get(\'repassword\'))
return \'注册成功\'
return render_template(\'register.html\')
