你给我提供一个 vue-amap 的代码吗 注意是vue-amap 代码功能为：（1）全屏展示地图以及地物的坐标信息，能够在地图上查询相关位置。（2）能够用鼠标画线闭合划定区块，标注显示区块的信息，对所划定区块进行面积计算。（3）能够用鼠标选择某个地点 进行标注 填写信息

好的，下面是一个使用 vue-amap 实现的地图功能的代码示例：

<template>
  <div>
    <amap :zoom="zoom" :center="center" :plugins="plugins" :events="events">
      <amap-tool-bar :offset="offset"></amap-tool-bar>
      <amap-scale :offset="offset"></amap-scale>
      <amap-overview :offset="offset"></amap-overview>
      <amap-control-bar :position="position"></amap-control-bar>
      <amap-circle :center="[lng, lat]" :radius="radius" :options="circleOptions"></amap-circle>
      <amap-polygon v-for="polygon in polygons" :key="polygon.id" :path="polygon.path" :options="polygonOptions" @click="showPolygonInfo(polygon)"></amap-polygon>
      <amap-marker v-for="marker in markers" :key="marker.id" :position="marker.position" :options="markerOptions" @click="showMarkerInfo(marker)"></amap-marker>
      <amap-info-window v-if="selectedMarker" :position="selectedMarker.position" :isCustom="true">
        <div class="info-window">
          <h3>{{selectedMarker.title}}</h3>
          <p>{{selectedMarker.content}}</p>
        </div>
      </amap-info-window>
      <amap-info-window v-if="selectedPolygon" :position="selectedPolygon.center" :isCustom="true">
        <div class="info-window">
          <h3>{{selectedPolygon.name}}</h3>
          <p>面积：{{selectedPolygon.area.toFixed(2)}} 平方米</p>
        </div>
      </amap-info-window>
      <amap-mouse-tool :events="mouseToolEvents"></amap-mouse-tool>
    </amap>
  </div>
</template>

          tool.on('draw', (e) => {
            if (e.obj.CLASS_NAME === 'AMap.Polygon') {
              const polygon = {
                id: new Date().getTime(),
                name: '',
                path: e.obj.getPath(),
                area: e.obj.getArea()
              }
              this.polygons.push(polygon)
              this.selectedPolygon = polygon
              tool.close(true)
            }
          })
        }
      }
    }
  },
  methods: {
    showMarkerInfo(marker) {
      this.selectedMarker = marker
    },
    showPolygonInfo(polygon) {
      this.selectedPolygon = polygon
    }
  },
  mounted() {
    AMap.initAMapApiLoader({
      key: 'your amap key',
      plugin: ['AMap.MouseTool'],
      callback: () => {
        console.log('amap loaded')
      }
    })
  }
}
</script>

这个代码实现了以下功能：

1. 在地图上展示一个圆形和多个多边形和标注点；
2. 点击多边形或标注点，会在地图上显示对应的信息窗口；
3. 使用鼠标画多边形，会在地图上添加一个新的多边形，并计算出其面积。

需要注意的是，为了使代码正常运行，需要在代码中填写自己的高德地图开发者 key。
