我想用PHP的cURL来访问WeatherWS
官网给出的请求示例：
1
540POST /WebServices/WeatherWS.asmx/getWeather HTTP/1.1
Host: www.webxml.com.cn
Content-Type: application/x-www-form-urlencoded
Content-Length: length
theCityCode=string&theUserID=string我写的代码：
$data = 'theCityCode=广州&theUserID=""';
$curlObj = curl_init();
curl_setopt($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)));
$rtn = curl_exec($curlObj);
if(!curl_errno($curlObj)){
echo $rtn;
}else{
echo 'Curl error:'.curl_error($curlObj);
}
curl_close($curlObj);说是免费用户的话theUserID留空，可是执行的结构就是
发现错误：用户验证失败。http://www.webxml.com.cn/如果不加入theUserID又会提示：
缺少参数: theUserID。求解？？
