通过curl从url获取JSON数据
问题描述：
我正在尝试通过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，我想获得以上内容。
I am trying to get JSON data from the url via curl connection. When I open the link: it shows {"version":"N/A","success":true,"status":true}.
Now, I want to get above content.
到目前为止，我已经使用过：
So far I have use this:
$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，有人知道哪里错了吗？
However, I always get NULL, Does someone have idea where is wrong?
答
网站检查用户代理。添加代理选项，它将起作用。
The website check the user agent. Add an agent option, and it will work.
$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));
