SSL Redirection in CakePHP

Question

当任何用户在cakePHP中键入“ http://www.example.com ”时，我们如何将“ http://www.example.com ”重定向到“ https://www.example.com ”？

Answer 1

You can use a .htacces file to do it before loading any php. Then the servers doesn't need to load the PHP scripts

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L]

Answer 2

While the currently accepted answer focuses on the use of apache's rewrite module, there are a number of cases where this answer doesn't apply, for an obvious example when apache isn't used at all or when rewrite module isn't and can't be enabled.

So a more generic answer would involve you adding this to your AppController

public function beforeFilter(Event $event) {
    if (!env('HTTPS')) {
        return $this->redirect('https://' . $this->request->host() . $this->request->here(), 301);
    }
}

Which would make a permanent redirect to the same url under https if https isn't used.

You don't specify cake's version so the above is cakephp 3 code, just remove Event $event from the function arguments to make it cake 2.
