url: 'https://dev.virtualearth.net',
key: 'YOUR_BING_MAPS_KEY'
});
调用geocode
方法:
bingMapsGeocoder.geocode('纽约市').then(result => {
console.log(result);
}).catch(error => {
console.error(error);
});
geocode
方法返回一个Promise对象,该对象解析为地理编码数据。地理编码数据包含以下属性:
{
displayName: 'New York, NY, USA',
destination: Cartesian3.fromDegrees(-73.935242, 40.730610),
entityType: 'PopulatedPlace',
