檢查表單提交的URL是否具有HTTPS

Question

我有一個腳本，檢查當前頁面的SSL，但我需要它的工作，所以當用戶輸入一個URL到表單並點擊提交按鈕，它會請回復說「你輸入的URL具有SSL」，或者如果沒有，則返回「本網站沒有SSL」。

這裏是我的PHP代碼：

if (!empty($_SERVER['HTTPS'])) { 
 
      echo "<p>This page does not have SSL. It would be worth adding SSL to this website as it's a ranking factor</p>"; 
 
     }else{ 
 
      echo '<p>Good job, this page has SSL.</p>'; 
 
     }

在此先感謝。

Answer 1

看來，你允許用戶查看他們的網站，基於這一點，你可以使用：

$url = parse_url('https://user.url'); 
if($url['scheme'] == 'https') 
{ 
    echo '<p>Good job, this page has SSL.</p>'; 
}else{ 
    echo "<p>This page does not have SSL. It would be worth adding SSL to this website as it's a ranking factor</p>"; 
}

OLD答案 - 並不適用於任擇議定書的答案，但可以有用的檢查當前的URL是使用HTTPS：

if ($_SERVER['REQUEST_SCHEME'] == "https") 
{ 
    echo '<p>Good job, this page has SSL.</p>'; 
}else{ 
    echo "<p>This page does not have SSL. It would be worth adding SSL to this website as it's a ranking factor</p>"; 
} 

您還可以使用：

if (isset($_SERVER['HTTPS']) && 'on' === $_SERVER['HTTPS']) 
{ 
    echo '<p>Good job, this page has SSL.</p>'; 
}else{ 
    echo "<p>This page does not have SSL. It would be worth adding SSL to this website as it's a ranking factor</p>"; 
}

最後一個選項似乎是確定https最安全的方法。
