我在模态框中设置了一个表单，使用 POST 提交，遇到的问题是提交后收不到表单数据，第一次在模态框中写表单，求教是哪里的问题。

模态框代码:

    <!-- 模态框（ Modal ） -->     <form action="{{ url_for('dashboard.freeze_user') }}" method="POST">     <div class="modal fade" id="freeze_users" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">       <div class="modal-dialog">           <div class="modal-content">               <div class="modal-header">                   <h4 class="modal-title -align-center" id="myModalLabel">确定冻结该账户？</h4>                   </div>                   <div class="modal-body">                      <input type="username" name="user" id="user" value="" disabled="disabled">                     <input type="submit" class="btn btn-danger" value="确认">                     <button type="button" class="btn btn-dark" data-dismiss="modal">关闭</button>                    </div>           </div><!-- /.modal-content -->       </div><!-- /.modal -->     </div>     </form> 

后端代码：

@dashboard_bp.route('/api/users/freeze', methods=['POST']) @admins_only def freeze_user():     user = request.form.get("user")     print(request.data)     print(user)     # if user:     #     print(user)     return redirect(url_for('dashboard.users_info')) 

打印信息：
