我正在使用Google Places API获取某个地点的详细信息，但它没有返回照片的photo_reference属性。为什么？
以下是我如何称呼它：
var request = {
placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4'
};
service = new google.maps.places.PlacesService(document.createElement('div'));
service.getDetails(request, callback);
function callback(placeD, status) {
console.log( placeD );
console.log( JSON.stringify(placeD) );
if (status == google.maps.places.PlacesServiceStatus.OK) {
console.log( placeD );
}
}
这是回复

如果我使用此网址查看同一地点的详细信息，我可以获取photo_reference属性：
https://maps.googleapis.com/maps/api/place/details/json?reference=CmRaAAAAXa9Pjme9u0GwglGBnp5nlj_r92tKtn3rY9mx22RTSHhZSNnYd3RvNVzl33PB_7qyhodZq_KkKx2KH9JIB0NYXuUNgVz2UKO_OMakrvJGVNrJ2Y6ue78-OVBtO6y5NdE0EhBCQrgjqWR2H2rv2ZWZrmPcGhT_f4ZFK2OYBor8uimEqGIwtBTfew&sensor=false&key=AIzaSyAmUTQw6a8sQESv77boQhf3tvTsaAJy09c

使用javscript库时，照片对象有一个方法＆＃34; getUrl＆＃34;而不是photo_reference。这有点令人困惑，但你可以循环覆盖这些图像，并使用maxHeight和/或maxWidth调用该方法（至少其中一个必须存在），它将返回一个照片网址。
https://developers.google.com/maps/documentation/javascript/3.exp/reference#PlacePhoto
function callback(placeD, status) {
console.log( placeD );
console.log( JSON.stringify(placeD) );
if (status == google.maps.places.PlacesServiceStatus.OK) {
placeD.photos.forEach(photo => {
console.log(photo.getUrl({maxHeight: 300})) // will log a url but no photo_reference
})
}
}
不幸的是，我还没有弄清楚如何从javascript库中获取photo_reference。

您需要从Place Search或Place Details请求中获取照片参考。
Google Places API网络服务的Place Photo service是一个只读API，可让您为应用添加高质量的照片内容。
当您使用地方详情请求获取地点信息时，将返回相关照片内容的照片参考。
对Place Photo服务的所有请求必须包含photoreference。它是唯一标识照片的字符串标识符。照片参考从地方搜索或地方详情请求中返回。
photos[]数组的示例如下所示。
...
"photos" : [
{
"html_attributions" : [],
"height" : 853,
"width" : 1280,
"photo_reference" : "CnRvAAAAwMpdHeWlXl-lH0vp7lez4znKPIWSWvgvZFISdKx45AwJVP1Qp37YOrH7sqHMJ8C-vBDC546decipPHchJhHZL94RcTUfPa1jWzo-rSHaTlbNtjh-N68RkcToUCuY9v2HNpo5mziqkir37WU8FJEqVBIQ4k938TI3e7bf8xq-uwDZcxoUbO_ZJzPxremiQurAYzCTwRhE_V0"
}
...
地方照片请求是以下格式的HTTP网址：
