元服务如何获取逆地理编码

import { site } from '@kit.MapKit';
@Entry
@Component
struct Demo {
  build() {
    Button('查询逆地理编码')
      .onClick(async () => {
        let params: site.ReverseGeocodeParams = {
          location: {
            latitude: 31.984410259206815,
            longitude: 118.76625379397866

          language: 'cn',
          radius: 200
        };
        try {
          const result = await site.reverseGeocode(params);
          console.info(`逆地理编码查询成功: ${JSON.stringify(result)}`);
        } catch (err) {
          console.error(`逆地理编码查询失败, fail err =  ${JSON.stringify(err)}`);
        }
      })
  }
}
