#login.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>请登陆会员账号</title> </head> <body> <h2>请登陆您的会员账号</h2> <form action='{{ url_for('.redirect_to_new_url') }}' method="POST"> <table> <tr> <td>会员名：</td> <td><input type="text" name='username' placeholder="Username" value="BIKMIN"></td> </tr> <tr> <td>密码：</td> <td><input type="password" name='password' placeholder="Password"></td> </tr> <tr> <td><input type="submit" value="登陆"></td> </tr> </table> </form> </body> </html>
