php – 通过curl从url获取JSON数据

Posted 2022-07-18 lxwphp

我试图通过curl连接从URL获取JSON数据.当我打开链接时：它显示“version”：“N / A”,“success”：true,“status”：true.
现在,我希望获得以上内容.

到目前为止我使用了这个：

$loginUrl = ‘http://update.protect-website.com/index.php?plugin=firewall&action=getVersion‘;
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$loginUrl);
$result=curl_exec($ch);
curl_close($ch);
var_dump(json_decode($result));

　　但是,我总是得到NULL,有人知道哪里出错了吗？

该网站检查用户代理.添加代理选项,它将起作用.

$loginUrl = ‘http://update.protect-website.com/index.php?plugin=firewall&action=getVersion‘;
$agent= ‘Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)‘;

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$loginUrl);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
$result=curl_exec($ch);
curl_close($ch);
var_dump(json_decode($result));
