我的脚本是从Google apis中对lat进行地理编码.它在我的托管服务提供商服务器上在线工作,但不在localhost上工作..为什么？

$latlng = "44.3585230889,8.57745766643";
$lang = "it";
$geocodeURL = "http://maps.googleapis.com/maps/api/geocode/json?latlng=$latlng&sensor=false&language=$lang";

$ch = curl_init($geocodeURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

if ($httpCode == 200) {
    $geocode = json_decode($result);

    $location   = $geocode->results[0]->address_components[0]->long_name;
    $city       = $geocode->results[0]->address_components[1]->long_name; 
    $province   = $geocode->results[0]->address_components[2]->long_name; 
    $region     = $geocode->results[0]->address_components[3]->long_name;
    $country    = $geocode->results[0]->address_components[4]->long_name;

    $geo_status = $geocode->status;     
    $geo_str    = "$location, $city, $province, $region, $country";
} else {
    $geo_status = "HTTP_FAIL_$httpCode";
    $geo_str    = "Failed: $geo_status";
}

Answer 1

这不是关于代理,而是关于如何使用googleapis.

添加CURLOPT_SSL_ on您的代码并将其设置为false

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

Answer 2

在具有自签名证书的本地服务器（例如 XAMPP）上，您必须使用：

curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, false);

注意：尽管对于测试环境来说不安全，但它解决了问题。
记得激活生产服务器！

Answer 3

这可能是防火墙问题.默认情况下,卷曲尝试使用端口1080,该端口可能未在您的localhost /路由器/ ISP上打开.
