取得地點評論

如要取得地點的評論資料，請在 fetchFields() 中加入 reviews 欄位請求參數產生的 Place 執行個體包含 Review 物件的陣列。以便取得需要的評論資訊。

以下範例顯示如何提出 Place Details 要求以取得評論。

// 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,
});
index.js

Review 執行個體包含下列項目：

AuthorAttribution
使用者提供的 rating。
publishTime (日期) 和 relativePublishTimeDescription (審核相對於目前時間的時間 (例如「一個月前」)。
評論「text」。
textLanguageCode 表示撰寫評論時使用的語言。

如要取得地點的整體評分，請使用 Place.rating 屬性 ( 要求 fetchFields() 要求參數中的 rating 欄位)。

作者資訊來源

顯示評論時，您必須一併顯示該評論的作者作者資訊。使用 AuthorAttribution敬上類別，傳回作者資訊。作者資訊包含作者姓名 (displayName)、Google 地圖個人資料的 URI (uri) 和 URI 供作者相片 (photoURI) 使用。下列程式碼片段顯示 displayName、uri 和 photoURI：

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