PHP：具有API的真實IP地址

Question

您好，我使用此api： http : //ipapi.co/json來獲得localhost（127.0.0.1）中的國家/地區，城市和真實IP地址，但工作正常，但是當我將代碼放入網站時，我的代碼未顯示地址客戶端，但服務器地址我該如何解決？

我可以用$_SERVER['REMOTE_ADDR'];獲得客戶端的IP地址$_SERVER['REMOTE_ADDR']; 但是我需要這個api來獲得國家和城市： http : //ipapi.co/json 。

Function TTT() {
    $ip = false;
    $city = false;
    $region = false;
    $country = false;
    $country_code = false;

    if($json = @file_get_contents("http://www.geoplugin.net/json.gp")) {
      $obj = json_decode($json);
      if(isset($obj->geoplugin_request) && $obj->geoplugin_request != false) {
        $ip = "IP: ". $obj->geoplugin_request. "</br>";
      }
      if(isset($obj->geoplugin_city) && $obj->geoplugin_city != false) {
        $city = "City: ". $obj->geoplugin_city. "</br>";
      }
      if(isset($obj->geoplugin_city) && $obj->geoplugin_city != false) {
        $region = "Region: ". $obj->geoplugin_city. "</br>";
      }
      if(isset($obj->geoplugin_countryName) && $obj->geoplugin_countryName != false) {
        $country = "Country: ". $obj->geoplugin_countryName. "</br>";
      }
      if(isset($obj->geoplugin_countryCode) && $obj->geoplugin_countryCode != false) {
        $country_code = "Country Code: ". $obj->geoplugin_countryCode. "</br>";
      }

      return $ip. $city. $region. $country. $country_code;
    }
}

echo TTT();

Answer 1

在http://ipapi.co/json使用api

$obj = json_decode($json);

將此JSON放入關聯數組中：

{
    "ip": "00.00.00.00",
    "city": "Atlanta",
    "region": "Georgia",
    "country": "US",
    "postal": "31532",
    "latitude": 34.461,
    "longitude": -85.9877,
    "timezone": "America/New_York"
}

像這樣訪問城市和地區：

if(isset($obj->city) && $obj->city != false) {
    $city = "City: ". $obj->city. "</br>";
  }
if(isset($obj->region) && $obj->region != false) {
    $region = "Region: ". $obj->region. "</br>";
  }

看來您沒有使用最初聲明的API。

您必須在對遠程服務的請求中包括訪問者的IP。 根據我的測試，您可以將客戶端IP地址放在如下網址中：

function TTT() {
    $ip = false;
    $city = false;
    $region = false;
    $country = false;
    $country_code = false;

    if($json = @file_get_contents("http://ipapi.co/" . $_SERVER['REMOTE_ADDR'] . "/json")) {
      $obj = json_decode($json);
      if(isset($obj->ip) && $obj->ip != false) {
        $ip = "IP: ". $obj->ip. "</br>";
      }
      if(isset($obj->city) && $obj->city != false) {
        $city = "City: ". $obj->city. "</br>";
      }
      if(isset($obj->region) && $obj->region != false) {
        $region = "Region: ". $obj->region. "</br>";
      }
      if(isset($obj->country) && $obj->country != false) {
        $country = "Country: ". $obj->country. "</br>";
      }

      return $ip. $city. $region. $country;
    }
}

echo TTT();

注意：該API的響應如下：

{
  "ip": "8.8.8.8",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "postal": "94035",
  "latitude": 37.386,
  "longitude": -122.0838,
  "timezone": "America/Los_Angeles"
}
