1.任务安排

需要完成申诉管理，主要用于管理未签到用户的申诉请求。管理员可以同意用户的申诉请求并修正签到信息，或者拒绝用户的申诉请求并填写拒绝理由。

2.任务分析

2.1显示待审核的申诉请求

找出所有审核申诉的结果为审核中申诉请求。返回给前端所需要的信息，并以对象数组的形式提供给前端，包括申诉id，教学名称，教室名称， 座位号，申诉人用户名 ，申诉时间，申诉缘由。其中申诉id可以不显示在前端，主要用于前端进行同意或拒绝操作时向唯一确定是哪一条申诉请求。排序方式按照申诉时间排序，时间早的申诉会排在前面。

2.2同意申诉请求

如果管理员同意用户的申诉请求，需要将申诉的结果从审核中变成已通过，并发消息告知该用户申诉已经通过。然后将用户对应的活动签到记录修改成已签到，已签退，未违约。然后去获取用户的违约次数，如果用户的违约次数是3，说明用户此时在黑名单里面，申诉成功之后违约次数就会减一，所以此时处于一个临界状态。再去根据用户的user_openid去查看黑名单表，如果用户被禁止参加的活动id不为空，那么就将是否禁止参加全部活动从1变成0，如果用户被禁止参加的活动id为空，那么就直接该条记录删除。并发送消息告知该用户已经被移出黑名单。

2.3拒绝申诉请求

如果管理员同意用户的申诉请求，需要将申诉的结果从审核中变成未通过。并发送消息告知该用户申诉没有通过。

3.具体代码
