调⽤天⽓服务
methods: {
predict() {
//调⽤百度API
//渭滨区
this.$('/bapi/weather/v1/?district_id=610302&data_type=all&ak=4PmNGerqU4hZujfCbGOWjTFwvfFQ73jq&output=json')        .then(response => {
this.pushPredata(response.data)
})
.catch(function (error) {
console.log(error);
});
//陈仓区

});
//凤县

},
...mapMutations('warning', ['pushPredata'])
},
}
</script>
效果：
使⽤百度API实现热⼒图
<script>
import {mapState} from 'vuex'
export default {
computed: {
...mapState('response', {tourists: 'items', location: 'location'})//将warning模块内items数据映射为data  },
data() {
return {}
},
methods: {
onPageLoad() {
var map = new BMapGL.Map("container");  // 创建地图实例
var point = new BMapGL.Point(107, 34);  // 创建点坐标
map.setTrafficOn();                              // 添加交通流量图层
var view = new mapvgl.View({
map: map
});
var heatmap = new mapvgl.HeatmapLayer({
size: 5000, // 单个点绘制⼤⼩
max: 300, // 最⼤阈值
height: 0, // 最⼤⾼度，默认为0
unit: 'm', // 单位，m:⽶，px: 像素
gradient: { // 对应⽐例渐变⾊
0.25: 'rgba(0, 0, 255, 0.8)',
0.55: 'rgba(0, 255, 0, 0.8)',
0.85: 'rgba(255, 255, 0, 0.8)',
1: 'rgba(255, 0, 0, 0.8)'
}
});
view.addLayer(heatmap);
heatmap.urists);
for (var i = 0; i < this.location.length; i++) {
var point = new BMapGL.Point(this.location[i][0], this.location[i][1]);
var opts = {
position: point,    // 指定⽂本标注所在的地理位置
offset: new BMapGL.Size(0, 15)    //设置⽂本偏移量
}
var label = new BMapGL.Label(this.location[i][2], opts);
label.setStyle({
color: 'black',
fontSize: '15px',
height: '20px',
lineHeight: '20px',
fontFamily: '微软雅⿊'
});
map.addOverlay(label);
}
}
},
mounted() {
}
}
