我正面临错误

警告：第一个参数必须是第17行的对象或现有类 public / visitor.php 的名称

function curl($url){

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$uaa = $_SERVER['HTTP_USER_AGENT'];
curl_setopt($ch, CURLOPT_USERAGENT, "User-Agent: $uaa");

return curl_exec($ch);

}
$ip = $_SERVER['REMOTE_ADDR'];
$ipdat = @json_decode(curl("http://www.geoplugin.net/json.gp?ip=" . $ip));
//get ISO2 country code
if(property_exists($ipdat, 'geoplugin_countryCode')) {
$local_visit = $ipdat->geoplugin_countryCode;
}

echo $local_visit;

Answer 1

试试这个：

$ip = $_SERVER['REMOTE_ADDR'];
$url="http://www.geoplugin.net/json.gp?ip=" . $ip;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$uaa = $_SERVER['HTTP_USER_AGENT'];
curl_setopt($ch, CURLOPT_USERAGENT, "User-Agent: $uaa");
$ipdat=json_decode(curl_exec($ch));

if(property_exists($ipdat, 'geoplugin_countryCode')) 
{
    $local_visit = $ipdat->geoplugin_countryCode;
}

Answer 2

我无法使用以下任何IP地址复制所述问题：

function curl($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "User-Agent: {$_SERVER['HTTP_USER_AGENT']}");
    return curl_exec($ch);
}
$ip   = '61.135.218.30'; /* youdao.com ~ chinese searchengine */
$url  = 'http://www.geoplugin.net/json.gp?ip='.$ip;
$data = curl( $url );

if( !empty( $data ) ){
    $json=json_decode( $data );
    echo ( is_object( $json ) && property_exists( $json,'geoplugin_countryCode') ) ? $json->geoplugin_countryCode : 'Unable to locate property in Object';
    echo '<pre>',print_r( $json,true ),'</pre>';
}

对上述电话的回复是：

CN
stdClass Object
(
    [geoplugin_request] => 61.135.218.30
    [geoplugin_status] => 200
    [geoplugin_credit] => Some of the returned data includes GeoLite data created by MaxMind, available from http://www.maxmind.com.
    [geoplugin_city] => Beijing
    [geoplugin_region] => Beijing
    [geoplugin_areaCode] => 0
    [geoplugin_dmaCode] => 0
    [geoplugin_countryCode] => CN
    [geoplugin_countryName] => China
    [geoplugin_continentCode] => AS
    [geoplugin_latitude] => 39.9289
    [geoplugin_longitude] => 116.3883
    [geoplugin_regionCode] => 22
    [geoplugin_regionName] => Beijing
    [geoplugin_currencyCode] => CNY
    [geoplugin_currencySymbol] => 元
    [geoplugin_currencySymbol_UTF8] => 元
    [geoplugin_currencyConverter] => 6.9112
)

使用isset()代替：）

if (isset($ipdat->geoplugin_countryCode)) {
    $local_visit = $ipdat->geoplugin_countryCode;
}

您需要在$local_visit条件之前初始化if变量，以避免未定义变量出现问题。
