那就是geocoordinates.php文件:
<?php
if(isset($_POST['lat'], $_POST['lng'])) {
$lat = $_POST['lat'];
$lng = $_POST['lng'];
$url = sprintf("https://maps.googleapis.com/maps/api/geocode/json?latlng=%s,%s", $lat, $lng);
$content = file_get_contents($url); // get json content
$metadata = json_decode($content, true); //json decoder
if(count($metadata['results']) > 0) {
// for format example look at url
// https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452
$result = $metadata['results'][0];
// save it in db for further use
echo $result['formatted_address'];
}
else {
// no results returned
}
}
?>
我发现这是前一个问题的答案,但是当我在浏览器上运行时,它给出了一个错误:用户拒绝了goelocation所以任何人都可以帮助?????
