Uzyskiwanie opinii o miejscu
Aby uzyskać dane opinii o danym miejscu, umieść na swoim koncie fetchFields()
pole reviews
parametrów żądania. Powstała w ten sposób instancja Place zawiera tablicę obiektów Review
,
w którym znajdziesz potrzebne informacje na temat weryfikacji.
Poniższy przykład pokazuje wysyłanie prośby o informacje o miejscu w związku z opiniami.
// Use a place ID to 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"], }); // 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 = ` <div id="title"><b>${place.displayName}</b></div> <div id="address">${place.formattedAddress}</div> <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 InfoWindow({ content: contentString, ariaLabel: place.displayName, });
Review
instancji zawiera następujące elementy:
AuthorAttribution
- Wartość
rating
podana przez użytkownika. publishTime
(data) irelativePublishTimeDescription
(opinia) w stosunku do bieżącego czasu, np. „miesiąc temu”).- Opinia
text
. - Element
textLanguageCode
wskazujący język, w którym napisana jest opinia.
Aby uzyskać ogólną ocenę miejsca, użyj właściwości Place.rating
(musisz
żądania pola rating
w parametrach żądania fetchFields()
).
Pochodzenie autora
Przy wyświetlaniu opinii musisz też podać informacje o jej autorach. Użyj
AuthorAttribution
do zwrócenia atrybucji. Podanie informacji o autorze zawiera imię i nazwisko autora
(displayName
), identyfikator URI profilu w Mapach Google (uri
) oraz identyfikator URI
dotyczące zdjęcia autora (photoURI
). Ten fragment kodu pokazuje zwracanie wartości
displayName
, uri
i photoURI
na potrzeby atrybucji.
let authorName = place.reviews[0].authorAttribution!.displayName; let authorUri = place.reviews[0].authorAttribution!.uri; let authorPhoto = place.reviews[0].authorAttribution!.photoURI;
