登录curl https空白php

Question

对不起，我想问为什么我的脚本只是空白？我想使用curl登录，但这个网站使用https，我想在登录后获取主页。我尝试下载证书，使用{{1 }，所以..如何使这个没有空白？

CURLOPT_CAINFO

这是来自inspect元素的html。

$ch = curl_init('https://ragnarok.gravindo.id/member/login_user');
// Enable HTTP POST
curl_setopt($ch, CURLOPT_POST, 1);

// Use SSL 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "/crt/gravindoid.crt");
// Set POST parameters
curl_setopt($ch, CURLOPT_POSTFIELDS, 'uname=*****&password=*****');
// Imitate classic browser's behavior - handle cookies
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$store = curl_exec($ch);

// Set file to download
curl_setopt($ch, CURLOPT_URL, 'https://ragnarok.gravindo.id/home');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "/crt/gravindoid.crt");
echo $content = curl_exec($ch);
curl_close($ch);
