使用百度的开放接口获取天气预报信息
在百度地图开放平台找了好久都没找到天气预报的api文档说明。以下的代码都是参考某个在用系统的天气预告部分代码来写的，写来测试测试。简单通过百度天气预报api获取天气预报的有关信息。简单的PHP代码如下：
";
echo "天气预报信息
";
print_r($result);
echo "
天气预报信息";
exit();
/*
* 用GET方式获取指定URL的数据
*/
function getData($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
?>网页输出情况如下：
