我正在尝试执行高程服务示例。我使用我的谷歌帐户创建了一个 API 密钥,然后单击“JAVASCRIPT + HTML”部分底部的“YOUR_API_KEY”链接,这帮助我从我的应用程序中选择了一个 API 密钥,然后被插入。然后我将代码复制并粘贴到我的机器上并运行示例,但是我收到以下错误:
此页面无法显示 Google 地图元素。提供的 Google API 密钥无效或本网站无权使用它。错误代码:InvalidKeyOrUnauthorizedURLMapError。
有没有人使用费用 API 密钥成功执行 Google Elevation Service 请求?
这是我尝试执行的代码:
<!DOCTYPE html>

<meta name="viewport" content="initial-scale=1.0, user-scalable=no">

}
#map {

}
</style>
</head>
<body>
<div id="map"></div>
<script>
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,
center: {lat: 63.333, lng: -150.5}, // Denali.
mapTypeId: 'terrain'
});
var elevator = new google.maps.ElevationService;
var infowindow = new google.maps.InfoWindow({map: map});
// Add a listener for the click event. Display the elevation for the LatLng of
// the click inside the infowindow.
map.addListener('click', function(event) {
displayLocationElevation(event.latLng, elevator, infowindow);
});
}
function displayLocationElevation(location, elevator, infowindow) {
// Initiate the location request
elevator.getElevationForLocations({
'locations': [location]
}, function(results, status) {
infowindow.setPosition(location);
if (status === google.maps.ElevationStatus.OK) {
// Retrieve the first result
if (results[0]) {
// Open the infowindow indicating the elevation at the clicked position.
infowindow.setContent('The elevation at this point <br>is ' +
results[0].elevation + ' meters.');
} else {
infowindow.setContent('No results found');
}
} else {
infowindow.setContent('Elevation service failed due to: ' + status);
}
});
}
</script>

更新:
我创建了一个浏览器密钥,现在代码可以工作了!谢谢!
