與谷歌的地理編碼地圖HTTP 500錯誤

Question

這裏是我的代碼：

public function geocode($address){ 
     $a = urlencode($address); 
     $geocodeURL = "http://maps.googleapis.com/maps/api/geocode/json?address=$a&sensor=false"; 
     $ch = curl_init($geocodeURL); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
     $result = curl_exec($ch); 
     $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
     curl_close($ch); 

     if ($httpCode == 200) { 
       $geocode = json_decode($result); 
       $lat = $geocode->results[0]->geometry->location->lat; 
       $lng = $geocode->results[0]->geometry->location->lng; 
       var_dump($lat); 
       var_dump($lng); 
       //return this->getClosest($lat, $lng); 
     } else { 
       $geo_status = "HTTP_FAIL_$httpCode"; 
       //return -1; 
     } 

    } 


    public function executeGet() 
    { 
     global $my_neighbor_lists; 
     $valid = $this->hasRequiredParameters($this->requiredParams); 
     if ($valid instanceof Frapi_Error) { 
      return $valid; 
     } 

     $origin_address = $this->getParam('origin', self::TYPE_STRING)); 
     $this->geocode($origin_address); 
    } 

爲什麼給我一個500 HTTP錯誤......有一些語法，我很想念？談到調用地理編碼刪除此錯誤

這裏是我的錯誤日誌：

2011/03/12十九時58分32秒[錯誤] 9966＃0：* 4555的FastCGI在標準錯誤發送：「PHP致命錯誤：在從上游讀取響應標頭時，調用未定義的函數curl_init（）在第128行的「/var/www/api/src/frapi/custom/Action/Find_route.php」，同時從客戶端讀取響應標頭：70.176.18.156，server：api.frapi，request ：「GET /route.printr?origin=1510%20E.%209th%20Street,%20Tucson,%20AZ & destination = 32％20North％20Campbell％20Avenue，％20Tucson，％20AZ HTTP/1.1」，upstream：「fastcgi： //127.0.0.1:9000「，主機：」api.adasherasdasbang.me「

Answer 1

這意味着未安裝cURL o你的系統。

您可能只需要在您的php.ini中啓用該模塊。請參閱http://www.php.net/manual/en/curl.installation.php
