//在WeatherWs的服务器上，默认大连城市的 theCityCode = 864

$data = &#39;theCityCode=864&theUserID=&#39;;
$curlobj = curl_init();

curl_setopt($curlobj,CURLOPT_URL,"http://www.webxml.com.cn/WebServices/WeatherWS.asmx/getWeather");
curl_setopt($curlobj,CURLOPT_HEADER,0);
curl_setopt($curlobj,CURLOPT_RETURNTRANSFER,1);
curl_setopt($curlobj,CURLOPT_POST,1);
curl_setopt($curlobj,CURLOPT_POSTFIELDS,$data);
curl_setopt($curlobj,CURLOPT_HTTPHEADER,array("application/x-www-form-urlencoded;charset=utf-8;","Content-length: ".strlen($data)));
curl_setopt($curlobj, CURLOPT_USERAGENT, &#39;Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.152 Safari/537.36&#39;);

$rtn = curl_exec($curlobj);
if(!curl_errno($curlobj)){
    echo $rtn;
}else{
    echo &#39;Curl error: &#39;.curl_errno($curlobj);
}
curl_close($curlobj);

?>
