使用手机信号塔信息的 Google 地理定位 - Curl 400 错误请求 PHP

我正在尝试使用以下方法从手机信号塔信息中获取纬度和经度谷歌的地理定位 API。 它需要一个有效的 JSON，其中包含 MCC、MNC、cellId、lac 等信息。我的 PHP post 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);

?>

但是我收到一条错误消息，指出响应中的请求错误。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 正确给出纬度和经度。我究竟做错了什么 ？

Try this
