Le recensioni dei luoghi ti consentono di aggiungere recensioni e valutazioni degli utenti alle tue pagine web. Questa pagina
spiega le differenze tra le recensioni dei luoghi utilizzate nelle classi Place
(nuova) e PlacesService
(legacy) e fornisce alcuni snippet di codice per
il confronto.
PlacesService
(legacy) restituisce un array di istanze PlaceReview
come parte dell'oggetto PlaceResult
per qualsiasi richiesta getDetails()
se il campo reviews
è specificato nella richiesta.
Place
(nuovo) restituisce un array di istanze Review
nell'ambito di una richiesta fetchFields()
se il campo reviews
è
specificato nella richiesta.
La seguente tabella elenca alcune delle principali differenze nell'utilizzo delle recensioni
di luoghi tra la classe Place
e PlacesService
:
PlacesService (legacy) |
Place (nuovo) |
Interfaccia PlaceReview |
Review |
I metodi richiedono l'utilizzo di un callback per gestire l'oggetto dei risultati e
la risposta google.maps.places.PlacesServiceStatus . |
Utilizza le promesse e funziona in modo asincrono. |
I metodi richiedono un controllo PlacesServiceStatus . |
Nessun controllo dello stato richiesto, è possibile utilizzare la gestione degli errori standard.
Ulteriori informazioni. |
PlacesService deve essere istanziato utilizzando una mappa o un elemento div. |
Place può essere istanziato ovunque sia necessario, senza un riferimento a una mappa o a un elemento della pagina. |
PlaceReview restituisce i dati di attribuzione per la recensione utilizzando i campi author_name , author_url e profile_photo_url . |
Review restituisce i dati di attribuzione per la recensione utilizzando
un'istanza
AuthorAttribution . |
Confronto del codice
Questa sezione confronta il codice per i metodi di ricerca di testo per illustrare le differenze
tra le recensioni di Place nella classe PlacesService
precedente e in quella Place
più recente.
Servizio Places (legacy)
Il seguente snippet chiama getDetails()
per richiedere i dettagli del luogo, incluse le recensioni, e mostra il primo risultato della recensione in una finestra informativa.
const request = {
placeId: "ChIJpyiwa4Zw44kRBQSGWKv4wgA", // Faneuil Hall Marketplace, Boston, MA
fields: ["name", "formatted_address", "geometry", "reviews"],

service.getDetails(request, (place, status) => {
if (
status === google.maps.places.PlacesServiceStatus.OK &&
place &&
place.geometry &&
place.geometry.location
) {
// If there are any reviews display the first one.
if (place.reviews && place.reviews.length > 0) {
// Get info for the first review.
let reviewRating = place.reviews[0].rating;
let reviewText = place.reviews[0].text;
let authorName = place.reviews[0].author_name;
let authorUri = place.reviews[0].author_url;
// Format the review using HTML.
contentString =`

<div id="rating"><p>Review: ${reviewText}</p></div>`;
} else {
contentString = `No reviews were found for ${place.name}`;
}
const infowindow = new google.maps.InfoWindow({
content: contentString,
ariaLabel: place.displayName,
});
// Add a marker.
const marker = new google.maps.Marker({
map,
position: place.geometry.location,

});
Place class (new)
Il seguente snippet chiama il metodo fetchFields()
per richiedere i dettagli del luogo, comprese le recensioni, e mostra il primo risultato della recensione in una finestra informativa.
// Use a place ID to create a new Place instance.
const place = new google.maps.places.Place({
id: "ChIJpyiwa4Zw44kRBQSGWKv4wgA", // Faneuil Hall Marketplace, Boston, MA
});

await place.fetchFields({
fields: ["displayName", "formattedAddress", "location", "reviews"],
});
// If there are any reviews display the first one.
if (place.reviews && place.reviews.length > 0) {
// Get info for the first review.
let reviewRating = place.reviews[0].rating;
let reviewText = place.reviews[0].text;
let authorName = place.reviews[0].authorAttribution.displayName;
let authorUri = place.reviews[0].authorAttribution.uri;
// Format the review using HTML.
contentString =`

<a href="${authorUri}" target="_blank">Author: ${authorName}</a>
<div id="rating">Rating: ${reviewRating} stars</div>
<div id="rating"><p>Review: ${reviewText}</p></div>`;
} else {
contentString = `No reviews were found for ${place.displayName}`;
}
// Create an infowindow to display the review.
infoWindow = new google.maps.InfoWindow({
content: contentString,
ariaLabel: place.displayName,
});
// Add a marker.
const marker = new google.maps.marker.AdvancedMarkerElement({
map,
position: place.location,
title: place.displayName,
});
// Show the info window.
infoWindow.open({
anchor: marker,
map,
