我正在使用谷歌地图Api,这就是我的工作:
我只使用文档中的示例...所以我不明白为什么会这样做!
这是我的代码:(查看控制台,地图上什么都没有,这是正常的)
var map;
var service;
// MapInit()
function MapInit() {
// Initial position, the problem doesn't come from the location, you can test
var initialPosition = new google.maps.LatLng(48.8589507, 2.2770201); // Paris
//var initialPosition = new google.maps.LatLng(40.6976701, -74.2598681); // New York
//var initialPosition = new google.maps.LatLng(35.6735408, 139.5703028); // Tokyo
// I create the map
map = new google.maps.Map(document.getElementById('map'), {
center: initialPosition,
zoom: 15
});
// I prepare the request for nearbySearch()
var request = {
location: initialPosition,
radius: '1000',
types: ['restaurant']
};
// I do the nearbySearch() request to found restaurants around the initial position
service = new google.maps.places.PlacesService(map);
service.nearbySearch(request, NearbySearchCallback);
}
// This function is called when nearbySearch() has done
function NearbySearchCallback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
// 20 results for this search
console.log("### All results for nearbySearch() ###");
for (var i = 0; i < results.length; i++) {
console.log(results[i].name);
}
// I do a new search for the details with getDetails(), but it will only return me 9 results instead of 20
console.log("### All results for getDetails() ###");
// For each results of the nearbySearch() request
for (var i = 0; i < results.length; i++) {
// I prepare the request for getDetails()
var place = results[i];
var request = {
placeId: place.place_id
};
// I do the getDetails() request for each results
service = new google.maps.places.PlacesService(map);
service.getDetails(request, getDetailsCallback);
}
}
}
// This function is called when getDetails() has done
function getDetailsCallback(place, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
console.log(place.name);
}
}
这是console.log:

我确定我错过了一些东西,但我已经知道了2天,我仍然不明白发生了什么。
如果我的代码完全错误,我的主要问题是:如何从20个结果中获得评论和评分?
非常感谢你的帮助。 :)
答案 0 :(得分:0)
所有Google的服务都受到费率限制和配额的限制。在执行长期限制(每秒约1次)之前,速率限制将您限制为大约10个结果。检查响应中的status
(您当前默默地忽略失败),如果OVER_QUERY_LIMIT
您需要放慢请求速度。如果您对用户操作执行详细信息请求(例如点击标记或链接,则不会出现此问题。)
