Question

我想通过php脚本获取计算机用户的地理位置（经度和纬度）。我正在使用这个

<?php

// Get lat and long by address      
        $address = $dlocation; // Google HQ
        $prepAddr = str_replace(' ','+',$address);
        $geocode=file_get_contents('http://maps.google.com/maps/api/geocode/json?address='.$prepAddr.'&sensor=false');
        $output= json_decode($geocode);
        $latitude = $output->results[0]->geometry->location->lat;
        $longitude = $output->results[0]->geometry->location->lng;

?>

但问题是，这使用真实地址，我只想让用户登录，询问他是否有权跟踪他（允许位置）以及他是否接受获得所需的值（经度和纬度）。它可以通过 IP地址或其他方式来确定他的位置，但问题是我希望这种方法对于代理和 pratically 完美无缺。 fakies。有关如何做到这一点的任何想法？非常感谢你！

Answer 1

我认为这就是你想要的。简单易用。感谢HTML5 see source here

<html>
<body>
<p id="demo">Click the button to get your coordinates:</p>
<button onclick="getLocation()">Try It</button>
<script>
var x=document.getElementById("demo");
function getLocation()
  {
  if (navigator.geolocation)
    {
    navigator.geolocation.getCurrentPosition(showPosition);
    }
  else{x.innerHTML="Geolocation is not supported by this browser.";}
  }
function showPosition(position)
  {
  x.innerHTML="Latitude: " + position.coords.latitude + 
  "<br>Longitude: " + position.coords.longitude;    
  }
</script>
</body>
</html>

下载geoip.inc - http://www.maxmind.com/download/geoip/api/php-20120410/geoip.inc， geoipcity.inc - http://www.maxmind.com/download/geoip/api/php-20120410/geoipcity.inc， geoipregionvars.php - http://www.maxmind.com/download/geoip/api/php-20120410/geoipregionvars.php，

GeoLiteCity.dat - http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz 请将GeoLiteCity.dat.gz转换为GeoLiteCity.dat和放入geoip命名文件夹

    include("application/libraries/geoip/geoipcity.inc");
    include("application/libraries/geoip/geoipregionvars.php");

    $giCity = geoip_open("application/libraries/geoip/GeoLiteCity.dat", GEOIP_STANDARD);

    $ip =$_SERVER['REMOTE_ADDR'];
    $record = geoip_record_by_addr($giCity, $ip);

    echo "Getting Country and City detail by IP Address <br /><br />";
    echo "IP: " . $ip . "<br /><br />";

    echo "Country Code: " . $record->country_code .  "<br />" .
    "Country Code3: " . $record->country_code . "<br />" .
    "Country Name: " . $record->country_name . "<br />" .
    "Region Code: " . $record->region . "<br />" .
    "Region Name: " . $GEOIP_REGION_NAME[$record->country_code][$record->region] . "<br />" .
    "City: " . $record->city . "<br />" .
    "Postal Code: " . $record->postal_code . "<br />" .
    "Latitude: " . $record->latitude . "<`enter code here`br />" .
    "Longitude: " . $record->longitude . "<br />" .
    "Metro Code: " . $record->metro_code . "<br />" .
    "Area Code: " . $record->area_code . "<br />" ;

为什么不使用我们的地理位置API？只需转到https://smartip.io并注册即可获得一个免费的API密钥，该密钥每月可在Free层上接受250,000个请求。要实现JQuery中所需的功能，只需使用以下代码段即可：

$.ajax ({
  type: "GET",
  url: "https://smartip.io/api/112.126.34.5/?api_key=[YOUR_API_KEY]",
  success: function(response) { alert(response); }
});

JSON响应对象将包含您需要的地理位置信息以及许多其他信息：

{
"ip": "72.229.28.185",
"ip-type": "ipv4",
"hostname": "cpe-72-229-28-185.nyc.res.rr.com",
"country": {
    "country-iso-code": "US",
    "country-two-letter-iso-code": "US",
    "country-name": "United States",
    "capital": "Washington",
    "is-in-europe": false,
    "is-metric": false,
    "country-geo-id": 6252001,
    "continent-name": "North America",
    "continent-code": "NA",
    "continent-geo-id": 6255149,
    "region-name": "New York",
    "region-code": "NY",
    "region-geo-id": 5128638
},
"location": {
    "city": "New York",
    "zip-code": "10009",
    "latitude": "40.7263",
    "longitude": "-73.9818",
    "timezone": "America/New_York",
    "metro-code": 501
}
