我目前正在开发一个门户网站,以利用 Google 地理位置 API,特别是 MAC 地址。
我正在使用 PHP 和 cURL 发送 API 请求,解码从 google 返回的 JSON 并用于测试目的,回显结果。
我目前的代码已成功向 Google 的 API 提交请求并收到没有错误的结果。
我遇到的问题是,返回的定位结果永远不会与 MAC 地址的位置相关,而总是与用于发送请求的 IP 地址相关。准确度数字也总是非常高(不准确)。
我已经使用地址中给出的建议谷歌输入对此进行了测试:
https://developers.google.com/maps/documentation/geolocation/intro#sample-requests
我可以使用 VPN 可靠地更改 API 返回的结果。我还确保我的请求中包含的“considerIP”是错误的。如果没有找到地理位置数据,API 应该返回 404 错误,但我总是得到 200 个代码和结果。
据我所知,我的 cURL 请求是正确的,但我完全不明白为什么 API 在使用他们自己建议的示例时会返回有关我的 IP 地址的信息。
代码如下所示:
function askGoogle(){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/geolocation/v1/geolocate?key=[MYAPIKEY]");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$JSONArray = array (
'considerIp' => 'false',
'wifiAccessPoints' =>
array (
0 =>
array (
'macAddress' => '00:25:9c:cf:1c:ac',
),
1 =>
array (
'macAddress' => '00:25:9c:cf:1c:ad',
),
),
);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($JSONArray));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$headers = array();
$headers[] = "Content-Type: application/json";
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: application/json", "Content-Length: 0"));
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
echo "The curl completion is ".$httpCode."<br>";
$message = json_decode($result, true); //converts the returned JSON message into an array.
print_r(array_values($message));
echo "<br>";
curl_close ($ch);
}
我让你的代码工作了。我相信您的请求从 API 返回默认的基于 ip 的响应的两个原因是您在数组上使用 http_build_query 而不是 json_encode,并且因为标头中的内容长度为 0 而不是 json 有效负载的字符串长度。
function askGoogle()
{
$ch = curl_init();
curl_setopt(
$ch,
CURLOPT_URL,
"https://www.googleapis.com/geolocation/v1/geolocate?key=[MYAPIKEY]"
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$payloadArray = [
'considerIp' => false,
'wifiAccessPoints' => [
[
'macAddress' => '00:25:9c:cf:1c:ac',
"signalStrength" => -25,
"signalToNoiseRatio" => -101
],
[
'macAddress' => '00:25:9c:cf:1c:ad',
"signalStrength" => -25,
"signalToNoiseRatio" => -101
],
],
];
$payloadJson = json_encode($payloadArray);
curl_setopt(
$ch,
CURLOPT_HTTPHEADER,
["Content-type: application/json", "Content-Length: ".strlen($payloadJson)]
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadJson);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
echo "The curl completion is ".$httpCode."<br>";
$message = json_decode($result, true); //converts the returned JSON message into an array.
print_r($message);
echo "<br>";
curl_close($ch);
}
askGoogle();
我按照这个例子,但无论我添加什么MAC,它都会给出404 not found
