php如何使用cURL调用WebService来取得天气信息（代码）

相关代码如下：

<?php
$data = 'theCityName=杭州';
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,"http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getWeatherbyCityName");
curl_setopt($curl,CURLOPT_HEADER,0);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl,CURLOPT_POST,1);
curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
curl_setopt($curl,CURLOPT_HTTPHEADER,array(
"application/x-www-form-urlencoded;
charset=utf-8",
"Content-length: ".strlen($data)
));
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.62 Safari/537.36');
$result = curl_exec($curl);
if (!curl_errno($curl)) {
echo $result;
} else {
echo 'Curl error:' . curl_error($curl);
}
curl_close($curl);
