如何在react-native中获取用户位置

import { Geolocation } from 'react-native';

Geolocation.requestAuthorization();

Geolocation.getCurrentPosition(
  position => {
    const latitude = position.coords.latitude;
    const longitude = position.coords.longitude;
    // 处理获取到的位置信息
  },
  error => {
    // 处理获取位置失败的情况
  },
  { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 }
);

const watchId = Geolocation.watchPosition(
  position => {
    const latitude = position.coords.latitude;
    const longitude = position.coords.longitude;
    // 处理位置变化
  },
  error => {
    // 处理获取位置失败的情况
  },
  { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 }
);

Geolocation.clearWatch(watchId);
