请教一个 Flask 中模态框中提交表单的问题

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：
