处理方式： (很草率啊.. 赶得紧，就先这样。)

$pinyin = new \Pin\Pinyin\pinyin();
$result = $pinyin->pinyin(substr(I('post.city'), 0, -1)); // 将接收的城市名称转换为拼音
$url = 'http://flash.weather.com.cn/wmaps/xml/'.$result.'.xml';
$xml = $this->curl_get($url);   //   获取xml
$xml = (array)simplexml_load_string($xml,'SimpleXMLElement', LIBXML_NOCDATA);
$jsonArray = json_decode(json_encode($xml),true);  //   将xml 解析为普通数组
// 如果接口返回的值有两个以上
if ($jsonArray['city'][0] == null) {  
   $list['stateDetailed'] = $jsonArray['city']['@attributes']['stateDetailed'];
   $list['windPower'] = $jsonArray['city']['@attributes']['windPower'];
} else {
   $list['stateDetailed'] = $jsonArray['city'][0]['@attributes']['stateDetailed'];
   $list['windPower'] = $jsonArray['city'][0]['@attributes']['windPower'];
}
/**
  * curl get method
  */
  function curl_get($url){
      if(function_exists('file_get_contents')){
          $file_contents = file_get_contents($url);
      } else{
          $ch = curl_init();
          $timeout = 5;
          curl_setopt ($ch, CURLOPT_URL, $url);
          curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
