如何解析 Google 地图地理编码结果

Question

我想使用地理编码从给定的纬度和经度检索地理地址， 使用网站上给定的示例

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true

在这个例子中我只需要城市名称纽约和国家名称即美国。但问题是出现的次数不止一种 这些词作为long_name。

我的问题是如何在 php 中解析这个 json/xml 以获取城市名称和国家/地区。

$url= file_get_contents('http://maps.googleapis.com/maps/api/geocode/xml?latlng=40.714‌​224,-73.961452&sensor=true'); 
$xml = simplexml_load_string($url); 
$tracks = $xml->result; 
$temp; $city; $country; 
foreach($tracks as $key) 
{ 
    foreach($key->address_component as $val) 
    { 
        $temp= $val->long_name; 
        if($val->type=="locality") 
        { 
          $city=$temp; 
        }else if($val->type=="country") 
       { 
         $country=$temp; 
       }  
    }  
  } 
  echo $country."<br />"; echo $city;

Answer 1

您可以检查 google 响应 (json) 中的 3 个变量来查找当前城市名称。因此，该名称有 3 种不同的解释：

Country
     |
AdministrativeArea
     |
     |_AdministrativeAreaName (cityname)
     |
     |_Locality_LocalityName (cityname)
     | 
     |_SubAdministrativeArea
                 |
                 |_Locality_LocalityName (cityname)



if ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName != NULL) {

  $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName;

} elseif ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName != NULL) {

  $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName;

} 

如果您有多个地标，则需要循环遍历所有数组。

Answer 2

我有一个适用于 Google 地理编码 JSON 结果的简单解决方案。这是一个简单的 for 循环，返回字符串数组中的短版本和长版本。只需调用该函数并在参数中提供“类型”即可。

string[] street_number = GetJSONValueBasedOnType(record.geocode, "street_number");

    public string[] GetJSONValueBasedOnType(NewGoogleGeocode gc, string WhatYouWant)
{
    string[] returns = new string[2];
    returns[0] = string.Empty;
    returns[1] = string.Empty;
    bool isInIt;

    foreach (var v in gc.results[0].address_components)
    {
        isInIt = false;
        foreach (var t in v.types)
        {
            if (t == WhatYouWant)
            {
                isInIt = true;
            }
        }
        if (isInIt)
        {
            returns[0] = v.short_name;
            returns[1] = v.long_name;
        }
    }
    return returns;
}
