地理編碼地址 - 獲取某個地址（谷歌API）

Question

我有確切的地址（街道，無，城市，地區/區域，國家）的數據庫的地區。但是，我想知道如果我們在紐約，是否有辦法使用Google API獲取城市的區域（例如「曼哈頓」）？

所有我已經在數據庫中的其他信息，所以我只需要該地區是否有一個（當然這將是隻在較大的城市）...

UPDATE：

我在http://www.techques.com/question/1-3151450/Google-geolocation-API---Use-longitude-and-latitude-to-get-address上找到了這個功能，並試圖將formatted_address更改爲sublocality（即使其他人，如short_name等），但它不會返回任何內容......任何幫助將不勝感激！謝謝！！

function reverse_geocode($lat, $lon) { 
    $url = "http://maps.google.com/maps/api/geocode/json?latlng=$lat,$lon&sensor=false"; 
    $data = json_decode(file_get_contents($url)); 
    if (!isset($data->results[0]->formatted_address)){ 
     return "unknown Place"; 
    } 
    return $data->results[0]->formatted_address; 
} 

Answer 1

您可以訪問sublocality這樣的：

function reverse_geocode($lat, $lon) { 
    $url = "http://maps.google.com/maps/api/geocode/json?latlng=$lat,$lon&sensor=false"; 
    $data = json_decode(file_get_contents($url)); 
    if (!isset($data->results[0]->address_components)){ 
     return "unknown Place"; 
    } 

    if ($data->results[0]->address_components[2]->types[0]=="sublocality") { 

     $return_array['type']="sublocality"; 
     $return_array['sublocality_long_name']=$data->results[0]->address_components[2]->long_name; 
     $return_array['sublocality_short_name']=$data->results[0]->address_components[2]->short_name; 

     return $return_array; 
     } 

} 

Answer 2

你會發現一個地址解析請求這裏面的信息，當存在結果與types設置爲

[ "sublocality", "political" ] 

例子：317 Madison Ave,New York City

功能的修改以上易於訪問響應組件：

/** 
    * @param $a mixed latitude or address 
    * @param $b mixed optional longitude when $a is latitude 
    * @return object geocoding-data 
    **/ 

    function geocode($a, $b=null) { 
    $params=array('sensor'=>'false'); 
    if(is_null($b)) 
    { 
     $params['address']=$a; 
    } 
    else 
    { 
     $params['latlng']=implode(',',array($a,$b)); 
    } 
    $url = 'http://maps.google.com/maps/api/geocode/json?'.http_build_query($params,'','&'); 
    $result=@file_get_contents($url); 

    $response=new StdClass; 
    $response->street_address    = null; 
    $response->route      = null; 
    $response->country      = null; 
    $response->administrative_area_level_1 = null; 
    $response->administrative_area_level_2 = null; 
    $response->administrative_area_level_3 = null; 
    $response->locality     = null; 
    $response->sublocality     = null; 
    $response->neighborhood    = null; 
    $response->postal_code     = null; 
    $response->formatted_address   = null; 
    $response->latitude     = null; 
    $response->longitude     = null; 
    $response->status      = 'ERROR'; 

    if($result) 
    { 
     $json=json_decode($result); 
     $response->status=$json->status; 
     if($response->status=='OK') 
     { 
     $response->formatted_address=$json->results[0]->formatted_address; 
     $response->latitude=$json->results[0]->geometry->location->lat; 
     $response->longitude=$json->results[0]->geometry->location->lng; 

     foreach($json->results[0]->address_components as $value) 
     { 
      if(array_key_exists($value->types[0],$response)) 
      { 
      $response->{$value->types[0]}=$value->long_name; 
      } 
     } 
     } 
    } 
    return $response; 
} 

//sample usage 
echo '<hr/>'.geocode('317 Madison Ave,New York City')->sublocality; 
    //Manhattan 

echo '<hr/>'.geocode('foobar')->status; 
    //ZERO_RESULTS 

echo '<hr/>'.geocode('40.689758, -74.04513800000001')->formatted_address; 
    //1 Liberty Is, Brooklyn, NY 11231, USA

我想出了以下內容。

function geocode() { 
 
    var geocoder = new google.maps.Geocoder(); 
 
    var lat = $('#latitude').val() 
 
    var lng = $('#longitude').val() 
 
    var latlng = {lat: parseFloat(lat), lng: parseFloat(lng)}; 
 

 
    geocoder.geocode(
 
    {'location': latlng}, 
 
    function(results, status) { 
 
     if (status === 'OK') { 
 
     for (var i = 0; i < results[0].address_components.length; i++) 
 
     { 
 
      if (status == google.maps.GeocoderStatus.OK) { 
 
    \t \t \t \t if (results[0]) { 
 
    \t \t \t \t \t for (var i = 0; i < results.length; i++) { 
 
       //alert(results[i].types[0]+','+results[i].types[1]+','+results[i].address_components[0].long_name) 
 
       //district 
 
       if (results[i].types[0]=='political' && results[i].types[1]=='sublocality'){ 
 
        alert(results[i].address_components[0].long_name); 
 
       } 
 
       //City 
 
       if (results[i].types[0]=='locality' && results[i].types[1]=='political'){ 
 
        alert(results[i].address_components[0].long_name); 
 
       } 
 
       //country 
 
       if (results[i].types[0]=='country' && results[i].types[1]=='political'){ 
 
        alert(results[i].address_components[0].long_name); 
 
       } 
 
    \t \t \t \t \t } 
 
    \t \t \t \t } 
 
    \t \t \t \t else {console.log("No reverse geocode results.")} 
 
    \t \t \t } 
 
    \t \t \t else {console.log("Geocoder failed: " + status)} 
 

 

 
     } 
 
    }}) 
 
}
