我试图通过Google的Geocode API获取经度和经度。 $url我使用输出正确的JSON,但我的脚本中的某些内容无法正常工作。它没有输出$lati& $longi个变量。请查看以下脚本:

PHP:

<?php
$address   = 'Tempe AZ';
$address   = urlencode($address);
$url       = "https://maps.google.com/maps/api/geocode/json?sensor=false&address={$address}";
$resp_json = file_get_contents($url);
$resp      = json_decode($resp_json, true);

    if ($resp['status'] == 'OK') {
        // get the important data
        $lati  = $resp['results'][0]['geometry']['location']['lat'];
        $longi = $resp['results'][0]['geometry']['location']['lng'];
        echo $lati;
        echo $longi;

    } else {
        return false;
    }

?>

原来是一个代理问题。该主题帮助:Using proxy with file_get_contents

补充说:

$opts = array(
    'http' => array(
        'method' => "GET",
        'header' => "Accept-language: en\r\n".
        "Cookie: foo=bar\r\n",
        'proxy' => 'tcp://proxy.proxy.com:8080',
    )
);
$context = stream_context_create($opts);

// open the file using the HTTP headers set above
$file = file_get_contents($url, false, $context);

你的脚本也适合我。也许你会收到一个错误的电话:

$resp_json = file_get_contents($url);

如果发生这种情况,你应该这样做:

$resp_json = @file_get_contents($url);
 if ($resp_json === FALSE) {
  ///logic for exception
} else {
  ///do your logic hear
}

我在Laravel文件/类的顶部引入了Guzzle http包:请使用GuzzleHttp \ Client;

然后,要获取一个地址并将其转换为lat和lng以使用PHP / Laravel和Google Maps API保存,我在save()方法中添加了以下代码:

    // get latitude and longitude of address with Guzzle http package and Google Maps geocode API
    $client = new Client(); // GuzzleHttp\Client
    $baseURL = 'https://maps.googleapis.com/maps/api/geocode/json?address=';
    $addressURL = urlencode(request('street')) . ',' . urlencode(request('city')) . ',' . urlencode(request('state')) . '&key=' . env('GOOGLE_MAPS_API_KEY');
    $url = $baseURL . $addressURL;
    $request = $client->request('GET', $url);
    $response = $request->getBody()->getContents();
    $response = json_decode($response);
    $latitude = $response->results[0]->geometry->location->lat;
    $longitude = $response->results[0]->geometry->location->lng;
