4.天氣

車聯網API：http://developer.baidu.com/map/wiki/index.php?title=car/api/weather（接口說明-》天氣查詢）

 1 case "天氣":
 2                             $weatherurl="http://api.map.baidu.com/telematics/v3/weather?location=杭州&ak=f6UkU0QqVAhABUeGKSxZBCeb";
 3                             $apistr = file_get_contents($weatherurl);
 4                             $apiobj = simplexml_load_string($apistr);
 5                             $placeobj = $apiobj->results->currentCity;//讀取城市名
 6                             $todayobj = $apiobj->results->weather_data->date;//讀取當前時間
 7                             $weatherobj = $apiobj->results->weather_data->weather;//讀取天氣
 8                             $windobj = $apiobj->results->weather_data->wind;//讀取風力
 9                             $temobj = $apiobj->results->weather_data->temperature;//讀取溫度
10                             $pm25obj = $apiobj->results->pm25;//讀取pm2.5
11                             $contentStr = "{$placeobj}{$todayobj},天氣:{$weatherobj},風力:{$windobj},溫度:{$temobj},pm2.5:{$pm25obj}.";
12                             break;

還可以通過地理位置返回天氣信息。（case "location":略）
