我正在尝试使用Google 的 geolocation api从手机信号塔信息中获取纬度和经度。它需要一个包含 MCC、MNC、cellId、lac 等信息的有效 JSON，我的 PHP 发布请求如下所示。

<?php
header("Access-Control-Allow-Origin: *");

$mcc = $_POST["mcc"];
$mnc = $_POST["mnc"];
$cellId = $_POST["cellId"];
$lac = $_POST["lac"];

$post_array = array(
                "cellId" => (int) $cellId,
                "locationAreaCode" => (int) $lac,
                "mobileCountryCode" => (int) $mcc,
                "mobileNetworkCode" => (int) $mnc,
            );

$post_data = json_encode(array('cellTowers' => array($post_array)));

echo $post_data;


$url = "https://www.googleapis.com/geolocation/v1/geolocate?key=".$api_key; // not including api key here but its there in my code

$ch = curl_init();
curl_setopt_array($ch, array(
    CURLOPT_URL => $url,
    CURLOPT_POST => true,
    CURLOPT_HEADER => false,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_SSL_VERIFYHOST => 2,
    CURLOPT_HTTPHEADER => array(
        'Content-Type: application/json'
    ),
    CURLOPT_POSTFIELDS => $post_data
));
$result = curl_exec($ch);

echo "Result: ".$result;

curl_close($ch);

?>

但是，我在响应中收到错误请求。错误如下所示。

Result: {
 "error": {
  "errors": [
   {
    "domain": "geolocation",
    "reason": "invalidRequest",
    "message": "Bad Request"
   }
  ],
  "code": 400,
  "message": "Bad Request"
 }
}

我认为我的 JSON 格式不正确，但它正在使用以下命令行执行，所以这不是问题。

$ curl -d @your_filename.json -H "Content-Type: application/json" -i "https://www.googleapis.com/geolocation/v1/geolocate?key=API_KEY"

终端中的上述命令使用文件中的相同 JSON 正确提供纬度和经度。我究竟做错了什么 ？

尝试这个

    $DadosLBS['homeMobileCountryCode'] = $data['MCC'];
    $DadosLBS['homeMobileNetworkCode'] = $data['MNC'];
    $DadosLBS['radioType'] = 'gsm';
    $DadosLBS['carrier'] = $data['MNCOperator'];
    $DadosLBS['cellTowers'] = [
        [
            'mobileCountryCode' => $data['MCC'],
            'mobileNetworkCode' => $data['MNC'],
            'age' => $data['Age'],
            'timingAdvance' => $data['TA'],
