如何在 React Native Expo 中获取当前位置？

Question

我想在 React Native Expo 应用程序中获取当前天气。但是我需要我的当前位置来实现，所以我正在使用 Location.getCurrentPositionAsync({}) 并且我收到诸如“请求位置权限时出错”、“未授权使用位置服务”之类的错误

useEffect(() => {
        const fetchWeatherData = async (latitude, longitude) => {
          try {
            const response = await fetch(
              'https://api.openweathermap.org/data/2.5/weatherlat=${latitude}&lon=${longitude}&appid=3d9b9b12834e4fca69c88401aeb73c2e'
            );
            const json = await response.json();
            setWeatherData(json);
            console.log(weatherData.main.temp)
          } catch (error) {
            console.error('Error fetching weather data:', error);
          }
        };
        
        const getLocation = async () => {
            try {
              const granted = await PermissionsAndroid.request(
                PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
                {
                  title: 'Location Permission',
                  message: 'WeatherApp needs access to your location for fetching weather data.',
                  buttonNeutral: 'Ask Me Later',
                  buttonNegative: 'Cancel',
                  buttonPositive: 'OK',
                }
              );
      
              if (granted === PermissionsAndroid.RESULTS.GRANTED) {
                let location = await Location.getCurrentPositionAsync({});
                console.log(location)
                fetchWeatherData(location.coords.latitude, location.coords.longitude);

              } else {
                setLocationError('Location permission denied');
              }
            } catch (error) {
              console.error('Error requesting location permission:', error);
            }
          };
      
          getLocation();

    }, []);
