本節會比較地點相片的程式碼,說明 Places 服務和 Place 類別之間的差異。程式碼片段會顯示在各個 API 上要求地點相片所需的程式碼。
地點服務 (舊版)
下列程式碼片段顯示如何使用 PlacesService 傳回相片,並在網頁上顯示第一張相片結果。在本範例中,地點詳細資料要求會指定地點 ID,以及 name 和 photos 欄位。檢查服務狀態後,頁面會顯示第一張相片。
執行個體化 PlacesService 時,必須指定地圖或 div 元素;由於這個範例沒有地圖,因此使用 div 元素。
functiongetPhotos(){// Construct the Place Details request.constrequest={placeId:"ChIJydSuSkkUkFQRsqhB-cEtYnw",fields:["name","photos"],};// Create an instance of PlacesService.constattributionDiv=document.getElementById("attribution-div");constservice=newgoogle.maps.places.PlacesService(attributionDiv);// Check status and display the first photo in an img element.service.getDetails(request,(place,status)=>{if(status===google.maps.places.PlacesServiceStatus.OK && place){constphotoImg=document.getElementById('image-container');photoImg.src=place.photos[0].getUrl({maxHeight:400});}});}
PlacesService中的作者出處資訊
PlacesService 會以 html_attributions 字串形式傳回必要的作者出處資訊,其中包含指向作者 Google 個人資料頁面的網址。以下程式碼片段顯示如何擷取第一個相片結果的歸因資料。
下列程式碼片段顯示如何使用 fetchFields() 方法傳回地點詳細資料,包括顯示名稱和地點相片。首先,系統會使用地點 ID 例項化新的 Place 物件,然後呼叫 fetchFields(),並指定 displayName 和 photos 欄位。頁面隨即會顯示第一名相片。使用 Place 類別時,系統會自動處理服務狀態,因此不必檢查。
asyncfunctiongetPhotos(){// Use a place ID to create a new Place instance.constplace=newgoogle.maps.places.Place({id:'ChIJydSuSkkUkFQRsqhB-cEtYnw',// Woodland Park Zoo, Seattle WA});// Call fetchFields, passing the needed data fields.awaitplace.fetchFields({fields:['displayName','photos']});console.log(place.displayName);console.log(place.photos[0]);// Add the first photo to an img element.constphotoImg=document.getElementById('image-container');photoImg.src=place.photos[0].getURI({maxHeight:400});}
Place 類別中的作者出處資訊
Place 類別會以 AuthorAttribution 例項的形式傳回作者出處資訊,包括作者姓名、作者 Google 個人資料頁面的 URI,以及作者個人資料相片的 URI。以下程式碼片段顯示如何擷取第一張相片結果的歸因資料。

In the case of `textSearch()` and `nearbySearch()` the first place photo is returned by default if available.\n- The `Place` class returns an array of up to 10 [`Photo`](/maps/documentation/javascript/reference/place#Photo) objects as part of a `fetchFields()` request if the `photos` field is specified in the request.\n\nThe following table lists some of the main differences in the use of place\nphotos between the `Place` class and `PlacesService`:\n\n| [`PlacesService`](/maps/documentation/javascript/reference/places-service) (Legacy) | [`Place`](/maps/documentation/javascript/reference/place) (New) |\n|-----------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------|\n| [`PlacePhoto`](/maps/documentation/javascript/reference/places-service#PlacePhoto) interface | [`Photo`](/maps/documentation/javascript/reference/place#Photo) class |\n| `PlacePhoto` returns [`html_attributions`](/maps/documentation/javascript/reference/places-service#PlacePhoto.html_attributions) as a string. | `Photo` returns an [`AuthorAttribution`](/maps/documentation/javascript/reference/place#AuthorAttribution) instance. |\n| Methods require the use of a callback to handle the results object and `google.maps.places.PlacesServiceStatus` response. | Uses Promises, and works asynchronously. |\n| Methods require a `PlacesServiceStatus` check. | No required status check, can use standard error handling.

The code snippets show the code\nrequired to request place photos on each respective API.\n\n### Places service (legacy)\n\nThe following snippet shows returning photos using `PlacesService`, and\ndisplaying the first photo result on the page. In this example, the place\ndetails request specifies a place ID, along with the `name` and `photos` fields.\nThe first photo is then displayed on the page after checking service status.\nWhen instantiating the `PlacesService`, a map or a `div` element must be\nspecified; since this example does not feature a map, a `div` element is used. \n\n function getPhotos() {\n // Construct the Place Details request.\n const request = {\n placeId: \"ChIJydSuSkkUkFQRsqhB-cEtYnw\",\n fields: [\"name\", \"photos\"],\n };\n\n // Create an instance of PlacesService.\n const attributionDiv = document.getElementById(\"attribution-div\");\n const service = new google.maps.places.PlacesService(attributionDiv);\n\n // Check status and display the first photo in an img element.\n service.getDetails(request, (place, status) =\u003e {\n if (\n status === google.maps.places.PlacesServiceStatus.OK && place\n ) {\n const photoImg = document.getElementById('image-container');\n photoImg.src = place.photos[0].getUrl({maxHeight: 400});\n }\n });\n }\n\n#### Author attributions in `PlacesService`\n\nThe `PlacesService` returns the required author attributions as an\n[`html_attributions`](/maps/documentation/javascript/reference/places-service#PlacePhoto.html_attributions)\nstring containing a URL pointing to the author's Google profile page. The\nfollowing snippet shows retrieving attribution data for the first photo result. \n\n let attributionUrl = place.photos[0].html_attributions;\n\n#### Learn more\n\n- [See the documentation](/maps/documentation/javascript/places#places_photos)\n- [`getDetails` reference](/maps/documentation/javascript/reference/places-service#PlacesService.getDetails)\n- [`PlacePhoto` interface reference](/maps/documentation/javascript/reference/places-service#PlacePhoto)\n\n### Place class (new)\n\nThe following snippet shows using the\n[`fetchFields()`](/maps/documentation/javascript/reference/place#Place.fetchFields)\nmethod to return place details including the display name and place photos.\nFirst a new `Place` object is instantiated using a place ID, followed by a call\nto `fetchFields()` where the `displayName` and `photos` fields are specified.\nThe first place photo is then displayed on the page. There is no need to check\nservice status when using the `Place` class, as this is handled automatically. \n\n async function getPhotos() {\n // Use a place ID to create a new Place instance.\n const place = new google.maps.places.Place({\n id: 'ChIJydSuSkkUkFQRsqhB-cEtYnw', // Woodland Park Zoo, Seattle WA\n });\n\n // Call fetchFields, passing the needed data fields.\n await place.fetchFields({ fields: ['displayName','photos'] });\n\n console.log(place.displayName);\n console.log(place.photos[0]);\n // Add the first photo to an img element.\n const photoImg = document.getElementById('image-container');\n photoImg.src = place.photos[0].getURI({maxHeight: 400});\n }\n\n#### Author attributions in the `Place` class\n\nThe `Place` class returns author attributions as an\n[`AuthorAttribution`](/maps/documentation/javascript/reference/place#AuthorAttribution)\ninstance including the author's name, a URI for the author's Google profile\npage, and a URI for the author's profile photo. The following snippet shows\nretrieving attribution data for the first photo result. \n\n let name = place.photos[0].authorAttributions[0].displayName;\n let attributionUrl = place.photos[0].authorAttributions[0].uri;\n let photoUrl = place.photos[0].authorAttributions[0].photoUri;\n\n#### Learn more\n\n- [See the full example](/maps/documentation/javascript/examples/place-photos)\n- [See the documentation](/maps/documentation/javascript/place-photos)\n- [`fetchFields()` reference](/maps/documentation/javascript/reference/place#Place.fetchFields)\n- [`Photo` class reference](/maps/documentation/javascript/reference/place#Photo)"]]
