<pre class="brush:php;toolbar:false;">use Geocoder\Provider\GoogleMaps\GoogleMaps;
use Geocoder\Provider\Cache\ProviderCache;
use Geocoder\StatefulGeocoder;
use Http\Discovery\Psr18Client;
use Cache\Adapter\PHPArray\ArrayCachePool;
use Geocoder\Query\GeocodeQuery;

// 1. 创建一个HTTP客户端
$httpClient = new Psr18Client();

// 2. 创建一个地理编码Provider，例如Google Maps
$provider = new GoogleMaps($httpClient);

// 3. 创建一个PSR-6兼容的缓存驱动，例如ArrayCachePool
$psr6Cache = new ArrayCachePool();

// 4. 使用Geocoder Cache Provider包装地理编码Provider
$cachedProvider = new ProviderCache(
    $provider, // Provider to cache
    $psr6Cache, // PSR-6 compatible cache
    600 // Cache expiry, in seconds
);

// 5. 创建Geocoder实例
$geocoder = new StatefulGeocoder($cachedProvider, 'en');

// 第一次调用，会从Google Maps API获取数据
$result1 = $geocoder->geocodeQuery(GeocodeQuery::create('Buckingham Palace, London'));

// 第二次调用，会直接从缓存中获取数据，无需调用API
$result2 = $geocoder->geocodeQuery(GeocodeQuery::create('Buckingham Palace, London'));
