Pour obtenir des données d'avis sur un lieu, incluez le reviews champ dans les fetchFields()
paramètres de votre requête. L'instance Place résultante contient un tableau d'objets Review,
à partir duquel vous pouvez accéder aux informations d'avis nécessaires.
L'exemple suivant montre comment effectuer une requête Place Details pour obtenir des avis.
// Create a new Place instance. const place = new Place({ id: 'ChIJpyiwa4Zw44kRBQSGWKv4wgA', // Faneuil Hall Marketplace, Boston, MA }); // Call fetchFields, passing 'reviews' and other needed fields. await place.fetchFields({ fields: ['displayName', 'formattedAddress', 'location', 'reviews'], }); // Create an HTML container. const content = document.createElement('div'); const title = document.createElement('div'); const rating = document.createElement('div'); const address = document.createElement('div'); const review = document.createElement('div'); const authorLink = document.createElement('a'); // If there are any reviews display the first one. if (place.reviews && place.reviews.length > 0) { // Get info for the first review. const reviewRating = place.reviews[0].rating; const reviewText = place.reviews[0].text; const authorName = place.reviews[0].authorAttribution.displayName; const authorUri = place.reviews[0].authorAttribution.uri; // Safely populate the HTML. title.textContent = place.displayName || ''; address.textContent = place.formattedAddress || ''; rating.textContent = `Rating: ${reviewRating} stars`; review.textContent = reviewText || ''; authorLink.textContent = authorName; authorLink.href = authorUri || ''; authorLink.target = '_blank'; content.appendChild(title); content.appendChild(address); content.appendChild(rating); content.appendChild(review); content.appendChild(authorLink); } else { content.textContent = `No reviews were found for ${place.displayName}.`; } // Create an infoWindow to display the review. infoWindow = new InfoWindow({ content, ariaLabel: place.displayName, });
L'instance Review
contient les éléments suivants :
- Une
AuthorAttribution - La
ratingattribuée par l'utilisateur. - Le
publishTime(date) et lerelativePublishTimeDescription(heure de l'avis par rapport à l'heure actuelle, par exemple « il y a un mois »). - Le
textde l'avis. - Le
textLanguageCodeindiquant la langue dans laquelle l'avis est rédigé.
Pour obtenir la note globale du lieu, utilisez la Place.rating propriété (vous devez
demander le rating champ dans les paramètres de votre fetchFields() requête).
Attributions d'auteur
Lorsque vous affichez un avis, vous devez également afficher les attributions d'auteur correspondantes. Utilisez la
AuthorAttribution
classe pour renvoyer les attributions. Une attribution inclut le nom de l'auteur
(displayName), un URI pour son profil Google Maps (uri) et un URI
pour la photo de l'auteur (photoURI). L'extrait suivant montre comment renvoyer les éléments
displayName, uri et photoURI pour une attribution.
let authorName = place.reviews[0].authorAttribution!.displayName; let authorUri = place.reviews[0].authorAttribution!.uri; let authorPhoto = place.reviews[0].authorAttribution!.photoURI;
