项目实训第四周第二次记录
1.任务安排
完成了基本的要求，对于申诉管理和报修管理，在测试的过程中，发现了异常情况，导致向用户重复发送了多条消息并且使得用户的违约次数成为了负数。
2.任务分析
通过分析以及和前端同学进行沟通发现，由于前端同学没有设置操作成功后的提示信息，导致前端管理员对于同一个申诉请求多次进行了同意操作。在一开始的设计过程中，我认为同意申诉请求这一操作一旦完成之后，就会在前端展示的待审核的申诉请求列表中消失，从而无法再次进行申诉请求操作。因此，当前端传递给后端appeal_id时，默认该条申诉记录是待审核。但是这样不合理的，即使前端对于操作成功有相应的措施。比如可以通过Postman发送post请求之后，此时的appeal_id可以是任意的，并不能确定这条申诉请求是待审核的还是已经审核过了的。因此，我们需要在一开始根据传递给后端的appeal_id判断当前申诉请求的状态是否是待审核的。如何该申诉请求不是待审核的，那么将返回给前端0，而对于申诉请求是待审核的，那么将根据操作的数量返回对应的值。对于申诉请求的拒绝操作，保修操作的同意，拒绝和维修座位操作也是类似的。
