使用手机信号塔信息的谷歌地理定位 - Curl 400 Bad request PHP

问题描述

我正在尝试使用 Google 的手机信号塔信息获取纬度和经度地理位置API.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.

I'm trying to get latitude and longitude from cell tower info using Google's geolocation api. It requires a valid JSON with information like MCC, MNC, cellId, lac etc.., My PHP post request looks like this.

<?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.

However I get an error saying bad request in the response. The error is shown below.

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，但它正在执行以下命令行，所以这不是问题.

I thought my JSON was not in the correct format but it was working with the following command line execution, so that can't be the issue.

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

终端中的上述命令在文件中使用相同的 JSON 正确地给出纬度和经度.我做错了什么?

The above command in terminal gives lattitude and longitude properly with the same JSON in a file. What am I doing wrong ?

推荐答案

试试这个

    $DadosLBS['homeMobileCountryCode'] = $data['MCC'];
    $DadosLBS['homeMobileNetworkCode'] = $data['MNC'];
    $DadosLBS['radioType'] = 'gsm';

别忘了在谷歌控制台上创建我们的密钥.

Don't forget to create our key on google console.
