Questa guida evidenzia le principali differenze tra il servizio Places legacy e la nuova classe Place. L'upgrade alla classe Place offre vantaggi significativi, tra cui prestazioni migliorate e un nuovo modello di prezzo.
Per ottenere il massimo da Places e assicurarti che le tue app siano aggiornate, familiarizza
con le modifiche descritte in questa guida.
Best practice di fatturazione per la migrazione
warning_amber
Queste indicazioni si applicano se l'utilizzo dell'API è sufficientemente elevato da
passare al prezzo di secondo livello. Quando esegui la migrazione a una versione più recente di un'API,
ti viene addebitato anche un SKU diverso. Per evitare costi maggiori durante il mese di
transizione, ti consigliamo di passare alle nuove API in produzione il più vicino possibile all'inizio del mese. In questo modo, durante il mese della migrazione raggiungerai i livelli di prezzo mensili più convenienti. Per informazioni sui livelli di prezzo, consulta la pagina dei prezzi e le domande frequenti sui prezzi.
Abilita l'API Places
La classe Place si basa sul servizio API Places.
Per utilizzare le funzionalità della nuova classe Place, devi prima attivare l'API Places (New) nel tuo progetto Google Cloud. Per ulteriori
informazioni, consulta la guida introduttiva.
Modifiche generali
La seguente tabella elenca alcune delle principali differenze tra PlacesService
e Place:
La classe Place fornisce un'API per l'utilizzo della libreria Places e supporta
pattern di utilizzo moderni come le promesse. La classe Place espone gli stessi campi di dati e tipi di luogo del servizio Places legacy e include molti nuovi valori per i campi di dati e i tipi di luogo.
Questa tabella mostra la mappatura delle funzionalità del servizio Places
con quelle della classe Place:
Il modo in cui l'app carica la libreria Places dipende dal caricatore bootstrap in uso. Se la tua app utilizza l'importazione dinamica di librerie,
puoi caricare le librerie necessarie in fase di runtime utilizzando l'operatore await per
chiamare importLibrary(), come mostrato qui:
Questa sezione include le seguenti guide per aiutarti a eseguire la migrazione delle tue app in modo che utilizzino
la versione più recente dell'API Places:

Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nThis guide highlights key differences between the legacy\nPlaces Service and the new\nPlace class. Upgrading to the\nPlace class offers significant advantages,\nincluding improved performance and a new [pricing model](/maps/documentation/javascript/usage-and-billing#places-js-library).\nTo get the most out of Places and ensure your apps are up-to-date, familiarize\nyourself with the changes detailed in this guide.\n\n\nBilling best practices for migration\n------------------------------------\n\nwarning_amber\n\nThis guidance applies if your API usage is high enough to\nmove into second-tier pricing. When migrating to a newer version of an API,\nyou're also being billed for a different SKU. To avoid increased costs during the month of\nyour transition, we recommend switching to the new APIs in production as close to the\nbeginning of the month as possible. This will ensure that you reach the most cost-effective\nmonthly pricing tiers during the migration month. For information about pricing tiers,\nsee the [pricing page](/maps/billing-and-pricing/pricing)\nand the [pricing FAQ](/maps/billing-and-pricing/faq).\n\n\u003cbr /\u003e\n\nEnable Places API\n-----------------\n\nThe Place class relies on the Places API service.\nTo use the features of the new Place class, you\nmust first enable Places API (New) in your Google Cloud project.
