SpringBoot+Vue+百度地图实现定位打卡功能：

1、打卡sign表sql：

CREATE TABLE `sign` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '用户名称',
  `location` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '打卡位置',
  `time` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '打卡时间',
  `comment` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

2、获取百度开放平台AK：

https://lbsyun.baidu.com/index.php?title=%E9%A6%96%E9%A1%B5=》右上角控制台

3、定位=》获取当前位置：

【1】public=》index.html

<script type="text/javascript" src="https://api.map.baidu.com/api?v=1.0&type=webgl&ak=你的AK"></script>

【2】获取时间较长=》建议放在login.vue页面

mounted() {
    // 获取地理位置
    var geolocation = new BMapGL.Geolocation();
    geolocation.getCurrentPosition(function (r) {
      if (this.getStatus() == BMAP_STATUS_SUCCESS) {
        const province = r.address.province;
        const city = r.address.city;
        localStorage.setItem("location", province + city);
      }
    });
},

4、后台打卡逻辑：

hutool官网：https://www.hutool.cn/docs/#/core/%E6%97%A5%E6%9C%9F%E6%97%B6%E9%97%B4/%E6%97%A5%E6%9C%9F%E6%97%B6%E9%97%B4%E5%B7%A5%E5%85%B7-DateUtil

 // 新增或者更新
@PostMapping("/addOrUpdate")
public Result save(@RequestBody Sign sign) {
   if (sign.getId() == null) {  // 新增打卡
       String today = DateUtil.today();      //DateUtil是hutool工具类的
       QueryWrapper<Sign> queryWrapper = new QueryWrapper<>();
       queryWrapper.eq("user", sign.getUser());
       queryWrapper.eq("time", today);
       Sign one = signService.getOne(queryWrapper);
       if (one != null) {  // 打过卡了
           return Result.error("-1", "您已打过卡");
       }
       sign.setTime(today);
   }
   signService.saveOrUpdate(sign);//saveOrUpdate是mybits-plus工具类的
   return Result.success();
}

5、前端打卡功能：

<template>
  <div class="main">
    <div class="sign" @click="handleSign">打卡</div>
  </div>
</template>

<script>
export default {
  name: "BaiDuSign",
  data() {
    return {};
  },
  created() {},
  methods: {
    handleSign() {
      let userInfo = JSON.parse(localStorage.getItem("user"));
      let param = {
        location: localStorage.getItem("location"),
        user: userInfo.username,
      };
      this.request.post("/sign/addOrUpdate", param).then((res) => {
        if (res.success) {
          this.$message.success("打卡成功");
        } else {
          this.$message.error(res.msg);
        }
      });
    },
  },
};
</script>

<style  lang="less" scoped >
.main {
  .sign {
    width: 200px;
    height: 200px;
    border-radius: 50%;
    background: #1890ff;

    display: flex;
    align-items: center;
    justify-content: center;

    color: #fff;
    font-size: 30px;
    cursor: pointer;
    box-shadow: 0 0 10px rgba(0, 0, 0, 0.4);
  }
}
</style>
