bug: the page status was not changed after the vote

[zhanyeye]

缺陷描述：

进入投票页面后，第一次投票，页面没有变化；第二次投票出现异常，但前端异常信息为null, (这里其实是后端 Duplicate entry 'v_id-u_id' for key, 重复投票的异常)

问题分析：

投票后确实发送到后端了，但是前端没有正确切换到投票状态页面，后端异常信息也没提示 ”用户已投票“

• 前端异常log：

POST http://47.104.103.33:8089/api/vote/52 500 ()
{timestamp: "2021-12-03", status: 500, error: "Internal Server Error", message: "", path: "/api/vote/52"}

• 后端异常log:

Duplicate entry '52-27' for key 'vote_detail.UK61vpx1woxr2v6exm8a2hxwtgb'

• 原先投票之后，会取这里的值更新页面状态
