我正在尝试检测用户是否从欧洲国家/地区访问我的网站。我正在使用 Cloudflare 代理和 CDN，因此必须使用它们传递的 header (像这样):

$country_code = $_SERVER["HTTP_CF_IPCOUNTRY"];

我不确定我应该从 Cloudflare 监听哪些返回值可以让我做这样的事情:

if($location == '1' || $location == '2' || $location == '3'){
    // Europe
}else{
    // Not Europe
}

那么谁能帮我算出我应该处理的值？

感谢您的帮助!

最佳答案

$_SERVER["HTTP_CF_IPCOUNTRY"] 的值是一个国家代码。所以首先你需要一个 list所有欧洲国家代码。

$europe = array('AD', 'AL', 'AT', 'AX', 'BA', 'BE', 'BG', 'BY', 'CH', 'CZ', 'DE', 'DK', 'EE', 'ES', 'FI', 'FO', 'FR', 'GB', 'GG', 'GI', 'GR', 'HR', 'HU', 'IE', 'IM', 'IS', 'IT', 'JE', 'LI', 'LT', 'LU', 'LV', 'MC', 'MD', 'ME', 'MK', 'MT', 'NL', 'NO', 'PL', 'PT', 'RO', 'RS', 'RU', 'SE', 'SI', 'SJ', 'SK', 'SM', 'UA', 'VA');

然后您可以使用此列表来验证请求:

if(in_array($country_code, $europe)) {
  // Europe
} else {
  // Not Europe
}

如果您想定位特定区域，可以使用这些列表:

$eastern = array('BG', 'BY', 'CZ', 'HU', 'MD', 'PL', 'RO', 'RU', 'SK', 'UA');
$northern = array('AX', 'DK', 'EE', 'FI', 'FO', 'GB', 'GG', 'IE', 'IM', 'IS', 'JE', 'LT', 'LV', 'NO', 'SE', 'SJ');
$southern = array('AD', 'AL', 'BA', 'ES', 'GI', 'GR', 'HR', 'IT', 'ME', 'MK', 'MT', 'PT', 'RS', 'SI', 'SM', 'VA');
$western = array('AT', 'BE', 'CH', 'DE', 'FR', 'LI', 'LU', 'MC', 'NL');

例如:

if(in_array($country_code, $eastern)) {
  // Eastern Europe
} else {
  // Not Eastern Europe
}

我联系了 CloudFlare 以确保国家代码列表有效。他们向我发送了 $_SERVER["HTTP_CF_IPCOUNTRY"] 的可能值列表。我验证了上述数组，这些数组中的所有国家/地区代码都在可能值列表中。
