我用 cakephp 为移动应用程序开发后端
我有一个列出城市的函数,我想计算与这个城市的用户的距离,代码是:
$origins='origins=casablanca,maroc';
$destinations='&destinations=';
$url='http://maps.googleapis.com/maps/api/distancematrix/json?';
$this->paginate = array(
'limit' => 10,
'fields'=>array('cityId','cityFileName','cityName','stateId','stateFileName','stateName',
'countryCode','countryFileName','countryName','count(id) as num_hotels'),
'order' => 'num_hotels desc',
'group' =>array('cityId')
);
$hotels = $this->paginate();
for ($i = 0; $i < count($hotels); ++$i) {
$destination=($i==0?'':'|');
$destination.=$hotels[$i]['Hotel']['cityName'].','.$hotels[$i]['Hotel']['countryName'];
$destinations.=$destination;
}
$url.=$origins.$destinations.'&mode=driving&language=fr-FR&sensor=false';
$json = file_get_contents($url,0,null,null);
$details = json_decode($json, TRUE);
for ($i = 0; $i < count($hotels); ++$i) {
$hotels = Set::insert($hotels, $i.'.Hotel.distance',$details['rows']['0']['elements']['0']['distance']['value']);
}
$this->set(compact('hotels'));
$this -> viewPath = "hotels";
$this -> render("json/index","json/default");
问题是当我用第一页(分页)进行测试时,结果很好,但是当我访问其他页面> = 2时,我收到了这个警告,我无法获得距离
错误是:
Warning (2): file_get_contents(http://maps.googleapis.com/maps/api/distancematrix/json?origins=casablanca,maroc&destinations=Zagora,Morocco|Meknes,Morocco|Chefchaouen,Morocco|Tinghir,Morocco|M'hamid,Morocco|El Jadida,Morocco|Erfoud,Morocco|Skoura,Morocco|Tetouan,Morocco|Imlil,Morocco&mode=driving&language=fr-FR&sensor=false) [function.file-get-contents]: failed to open stream: HTTP request failed!
