谷歌地图无法加载控制html,谷歌地图javascript api。无法加载资源网络错误超时

我在google云平台上生成了一个api密钥,并将其放入脚本中,但仍然不起作用。

/* Set the size of the div element that contains the map */

#map {

height: 400px; /* The height is 400 pixels */

width: 100%; /* The width is the width of the web page */

}

// Initialize and add the map

function initMap() {

/ The location

var location = {lat: 36.512483,lng: -115.064985};

// The map, centered at location

var map = new google.maps.Map(

document.getElementById('map'), {zoom: 8, center: location});

// The marker, positioned at location

var marker = new google.maps.Marker({position: location, map: map});

}
