How to use CORS to implement JavaScript Google Places API request
Question
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>

@rd3n already answered about why to use Google Maps' SDK, but if you really need to use the API instead of SDK on a web app (reuse code, for exemple), you can bypass CORS using proxy parameter from Webpack's DevServer .
const GMAPS_PLACES_AUTOCOMPLETE_URL = (
process.env.NODE_ENV === 'production'
? 'https://maps.googleapis.com/maps/api/place/autocomplete/json'
: 'place-api' // on development, we'll use the Webpack's dev server to redirect the request
const urlParams = new URLSearchParams([
...
])
const response = await fetch(
`${GMAPS_PLACES_AUTOCOMPLETE_URL}?${urlParams}`,
{ method: 'GET' }
)
And on your webpack.config.js ...
module.exports = {
devServer: {
proxy: {
'/place-api': {
target: 'https://maps.googleapis.com/maps/api/place/autocomplete/json',
changeOrigin: true,
pathRewrite: { '^/place-api': '' }
}
}
}
}

Using the same url you provided, this is for pure front-end (React), but a less secure solution:
var requestURL = 'https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4&key=AIzaSyAW4CQp3KxwYkrHFZERfcGSl--rFce4tNw';
Cut out the following from url: 'https://maps.googleapis.com/maps/api/place' and create a proxy line in your package.json:
"proxy": "https://maps.googleapis.com/maps/api/place"
Then following google documentations you'll be left with the following code (wherever you're fetching the api):
var axios = require('axios');
var config = {
method: 'get',
url: '/details/json?placeid=ChIJN1t_tDeuEmsRUsoyG83frY4&key=AIzaSyAW4CQp3KxwYkrHFZERfcGSl--rFce4tNw', //the rest of your url
secure: false //important
};
axios(config)
.then(function (response) {
console.log(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});

I know this is an old question, and this might not be a direct answer to this question, but just in case someone could use this trick, I always like to go around this issue using PHP to create my own API, then fetch the newly created API using JavaScript:
1# Create an api.php file:
<?php
$google_URL = 'https://maps.googleapis.com/maps/api/place/details/json';
$api = 'YOUR_GOOGLE_API';
$place = 'PLACE_ID';
$field = [
'user_ratings_total',
'rating'
];
$fields = join(",", $field);
$result_url = $google_URL.'?placeid='.$place.'&fields='.$fields.'&key='.$api;
$result_content = file_get_contents($result_url);
$json_data = json_decode($result_content, true);
if ( isset($json_data) && $json_data['status'] === 'OK' ) {
echo json_encode($json_data['result']);
}else {
echo json_encode($json_data['error_message']);
}
header("content-type: application/json");
2# Create a script.js file:
const url = './api.php';
fetch(url)
.then(res => res.json())
.then(data => console.log(data))
.catch(error => console.log(error))
