我目前正在开发一个门户网站,以便使用Google Geo-location API,特别是针对MAC地址。
我正在使用PHP和cURL发送API请求,从谷歌解码返回的JSON并进行测试,以回应结果。
我目前已成功将请求提交给Google的API并收到没有错误的结果。
我遇到的问题是返回的位置结果从不与MAC地址的位置相关,而是始终与用于发送请求的IP地址相关。准确度数字也总是非常高(不准确)。
我使用地址中提供的建议谷歌输入进行了测试:
https://developers.google.com/maps/documentation/geolocation/intro#sample-requests
我可以使用VPN可靠地改变API返回的结果。我也确保我的请求包括'thinkIP'是假的。如果没有找到地理定位数据,API应该返回404错误,但是我总是得到200个包含结果的代码。
从我可以看到我的cURL请求是正确的,我完全不知道为什么API在使用他们自己的建议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);
}
答案 0 :(得分:1)
我的代码正常运行。我相信你的请求从API返回默认的基于ip的响应的两个原因是你在数组上使用http_build_query而不是json_encode,并且因为标头中的内容长度是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();
