Text Search (新版) 會採用文字查詢,並傳回相符地點清單。
Text Search (新版) 可根據字串 (例如「台南魯肉飯」、「西門町附近的鞋店」或「中正路 123 號」),傳回一組地點的相關資訊。這項服務會傳回與文字字串及位置自訂調整設定相符的地點清單。您可以運用 Text Search (新版) 按照類型搜尋地點、使用營業時間和評分等條件進行篩選,以及將結果的範圍限制或自訂調整為特定地點。
如要使用 Text Search (新版),請務必在 Google Cloud 專案中啟用「Places API (新版)」。詳情請參閱「開始使用」一文。
透過文字查詢尋找多個地點
呼叫 searchByText
即可根據文字查詢或電話號碼傳回地點清單。請使用要求來指定搜尋參數,然後呼叫 searchByText()
。系統會以 Place
物件清單的形式傳回結果,您可從中取得地點詳細資料。以下程式碼片段範例顯示一項要求,以及對 searchByText
的呼叫:
TypeScript
const request = { textQuery: 'Tacos in Mountain View', fields: ['displayName', 'location', 'businessStatus'], includedType: 'restaurant', locationBias: { lat: 37.4161493, lng: -122.0812166 }, isOpenNow: true, language: 'en-US', maxResultCount: 8, minRating: 3.2, region: 'us', useStrictTypeFiltering: false, }; //@ts-ignore const { places } = await Place.searchByText(request);
JavaScript
const request = { textQuery: "Tacos in Mountain View", fields: ["displayName", "location", "businessStatus"], includedType: "restaurant", locationBias: { lat: 37.4161493, lng: -122.0812166 }, isOpenNow: true, language: "en-US", maxResultCount: 8, minRating: 3.2, region: "us", useStrictTypeFiltering: false, }; //@ts-ignore const { places } = await Place.searchByText(request);
- 使用
textQuery
參數指定要搜尋的文字查詢或電話號碼。 - 您可以使用
fields
參數 (必要) 指定半形逗號分隔清單,其中包含一或多個採用駝峰式大小寫的資料欄位。 - 使用
includedType
參數,只傳回指定類型的結果。 - 使用
locationBias
或locationRestriction
,即可將 Text Search 結果限制或自訂調整為特定區域。
如果查詢內含電話號碼,請設定 region 參數。舉例來說,如果您使用電話號碼搜尋日本的地點,且要求網域為 jp
,就必須將 region
參數設為「jp」。如果在要求中省略 region
,API 會預設為美國 (「us」) 區域。
Place
物件清單的形式傳回結果,您可從中取得地點詳細資料。範例
以下範例使用 searchByText
查詢 Mountain View 附近的墨西哥捲餅餐廳,並在地圖中填入標記以顯示查詢結果。
