如何使用CORS实现JavaScript Google Places API请求 [英] How to use CORS to implement JavaScript Google Places API request
问题描述
我真的不明白我应该如何完成这项工作：
var requestURL ='https：// maps.googleapis.com/maps/api/place/details/json?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4&key=AIzaSyAW4CQp3KxwYkrHFZERfcGSl--rFce4tNw;
console.log（requestURL）;
$ b $ .getJSON（requestURL，function（data）{
// data
console.log（data）;
}）;
和我的HTML档案：
< body>
src =https://code.jquery.com/jquery-2.2.4.min.js
integrity =sha256-BbhdlvQf / xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44 =
crossorigin =anonymous>< / script>
< script src =main.jscharset =utf-8>< / script>
< / body>
我总是收到否'Access-Control-Allow-Origin'头部请求的资源。消息...即使我去
I really do NOT understand how I'm supposed to make this work:
var requestURL = 'https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4&key=AIzaSyAW4CQp3KxwYkrHFZERfcGSl--rFce4tNw';
console.log(requestURL);
$.getJSON( requestURL, function( data ) {
// data
console.log(data);
});
and my HTML file:
<body>
<script
src="https://code.jquery.com/jquery-2.2.4.min.js"
integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44="
crossorigin="anonymous"></script>
<script src="main.js" charset="utf-8"></script>
</body>
I always get the No 'Access-Control-Allow-Origin' header is present on the requested resource. message... even though if I go to https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4&key=AIzaSyAW4CQp3KxwYkrHFZERfcGSl--rFce4tNw in my browser I get the proper JSON returned.
I am lead to believe that CORS can help me here. I don't understand CORS. Please, can anyone help me in plain simple terms? What should I change to make this work??
Thanks
You are trying to use the Google Places API Web Service on client side whereas it is designed for server side applications. That's probably why appropriate CORS response headers are not set by the server.
As explained in the Notes at the beginning of the Place Details documentation, you should use the Places Library in the Google Maps JavaScript API:
If you're building a client-side application, take a look at the Google Places API for Android, the Google Places API for iOS, and the Places Library in the Google Maps JavaScript API.
Note: you will need to enable the Google Maps JavaScript API in your Google Developer Console first.
Here is a way you can proceed to get place details (based on the example from the documentation):
<head>
<script type="text/javascript">
function logPlaceDetails() {
var service = new google.maps.places.PlacesService(document.getElementById('map'));
service.getDetails({
placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4'
}, function (place, status) {
console.log('Place details:', place);
});
}
</script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAW4CQp3KxwYkrHFZERfcGSl--rFce4tNw&libraries=places&callback=logPlaceDetails"></script>
</head>
<body>
<div id="map"></div>
</body>
