4.天气

车联网API：http://developer.baidu.com/map/wiki/index.php?title=car/api/weather（接口说明-》天气查询）

 case "天气":
                             $weatherurl="http://api.map.baidu.com/telematics/v3/weather?location=杭州&ak=f6UkU0QqVAhABUeGKSxZBCeb";
                             $apistr = file_get_contents($weatherurl);
                             $apiobj = simplexml_load_string($apistr);
                             $placeobj = $apiobj->results->currentCity;//读取城市名
                             $todayobj = $apiobj->results->weather_data->date;//读取当前时间
                             $weatherobj = $apiobj->results->weather_data->weather;//读取天气
                             $windobj = $apiobj->results->weather_data->wind;//读取风力
                             $temobj = $apiobj->results->weather_data->temperature;//读取温度
                             $pm25obj = $apiobj->results->pm25;//读取pm2.5
                             $contentStr = "{$placeobj}{$todayobj},天气:{$weatherobj},风力:{$windobj},温度:{$temobj},pm2.5:{$pm25obj}.";
                             break;

还可以通过地理位置返回天气信息。（case "location":略）
