我正在使用Google Places API 检索有关地点的数据，但找不到如何获取该地点的图片，Google Places API 只是提供了不一样的图标。例如，我需要您在网络浏览器中搜索 Google 地图中的地点时获得的照片。 Panoramio 通常有更多图片，但 Panoramio API 只能按位置搜索图片，而不能按特定餐厅或酒店名称等搜索。有什么想法吗？

我正在创建一个 API，用于在给定 GPS 坐标的情况下获取最佳照片点/位置。有一个免费计划。
您有不同的端点，例如：
您可以在https://getnofilter.com/developers查看API文档
新端点即将推出。
如果您需要延长免费限制，可以给我发电子邮件，我可以做到（查看文档中的电子邮件）
【讨论】：
首先从响应中获取 photo_reference：
var photoRef;
if (data.results[i].photos && Array.isArray(data.results[i].photos)) {
photoRef = data.results[i].photos[0].photo_reference;
}
使用 Google Photos API 端点获取地点照片/图片：
https://maps.googleapis.com/maps/api/place/photo?maxwidth=960&photoreference="+ photoRef +"&key=AIzaSyBp0cy7ti0z5MJMAwWiPMNvbJobmWYGyv4' alt=''/>

【讨论】：
Places API 现在支持为 Place Search request 返回一张地点照片（如果有），为 Place Details request 返回最多十张地点照片。
如果您的请求返回了一个照片数组，您可以使用maxheight 和/或maxwidth、sensor 和key 参数将包含的照片对象中的photo_reference 传递给Place Photo request ：
https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CnRvAAAAwMpdHeWlXl-lH0vp7lez4znKPIWSWvgvZFISdKx45AwJVP1Qp37YOrH7sqHMJ8C-vBDC546decipPHchJhHZL94RcTUfPa1jWzo-rSHaTlbNtjh-N68RkcToUCuY9v2HNpo5mziqkir37WU8FJEqVBIQ4k938TI3e7bf8xq-uwDZcxoUbO_ZJzPxremiQurAYzCTwRhE_V0&sensor=false&key=AddYourOwnKeyHere
更多详情请查看documentation。
【讨论】：
Places API 刚刚添加了直接在 API 中请求照片的功能：https://developers.google.com/maps/documentation/javascript/places#places_photos
【讨论】：
Places API 将为您提供place detail response 中的坐标（纬度和经度）；然后您可以将坐标发送到Panoramio API。
例如（取自 API 文档中的示例）：
https://maps.googleapis.com/maps/api/place/details/json?reference=<big long key for place>&sensor=true&key=AIzaSyAiFpFd85eMtfbvmVNEYuNds5TEF9FjIPI

我们可以看到坐标是 “地点” ： { “纬度”：-33.8669710， “液化天然气”：151.1958750 }
然后我们可以向 Panoramio 发送请求，插入坐标，并在两边加上一点摆动空间（我做了 +/- 0.002 度，赤道处的形状为 200 m x 200 m 正方形，通常更小）。
http://www.panoramio.com/map/get_panoramas.php?set=public&from=0&to=20&minx=-33.868&miny=151.193&maxx=-33.864&maxy=151.197&size=medium&mapfilter=true
您可能需要对响应进行一些过滤以获得最近的照片，但这应该可以为您提供一些工作。

t necessarily give the picture of the right place but i guess its the closest you can get. Its just weird they have pics on website but dont 无论如何在地图或地点 api 中给他们
