Mencoba Contoh

Mendapatkan ulasan untuk suatu tempat

Untuk mendapatkan data ulasan tempat, sertakan kolom reviews dalam parameter permintaan fetchFields(). Instance Place yang dihasilkan berisi array objek Review, tempat Anda dapat mengakses informasi ulasan yang diperlukan.

Contoh berikut menunjukkan cara membuat permintaan Place Details untuk ulasan.

// 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,
});

Instance Review berisi hal berikut:

  • AuthorAttribution
  • rating yang diberikan oleh pengguna.
  • publishTime (Tanggal), dan relativePublishTimeDescription (waktu peninjauan relatif terhadap waktu saat ini, misalnya "satu bulan yang lalu").
  • Ulasan text.
  • textLanguageCode yang menunjukkan bahasa yang digunakan untuk menulis ulasan.

Untuk mendapatkan rating keseluruhan tempat, gunakan properti Place.rating (Anda harus meminta kolom rating dalam parameter permintaan fetchFields()).

Atribusi penulis

Saat menampilkan ulasan, Anda juga harus menampilkan atribusi penulis untuk ulasan tersebut. Gunakan class AuthorAttribution untuk menampilkan atribusi. Atribusi mencakup nama penulis (displayName), URI untuk profil Google Maps-nya (uri), dan URI untuk foto penulis (photoURI). Cuplikan berikut menunjukkan pengembalian displayName, uri, dan photoURI untuk atribusi.

  let authorName = place.reviews[0].authorAttribution!.displayName;
  let authorUri = place.reviews[0].authorAttribution!.uri;
  let authorPhoto = place.reviews[0].authorAttribution!.photoURI;
