CakePHP加密URL

Question

我正在尝试加密CakePHP中传递的URL。我遵循了这篇文章（http://bakery.cakephp.org/articles/yuri.salame/2008/07/15/encrypting-urls#），但它不起作用。我知道这是一篇旧文章。我正在使用CakePHP 2.x

以下是显示的错误：

Notice (8): Undefined index: url [APP/webroot/index.php, line 108]
Warning (4096): Argument 1 passed to Dispatcher::dispatch() must be an instance of CakeRequest, null given, called in /home/xxx/domains/xxx.com/public_html/xxx/v3/app/webroot/index.php on line 110 and defined [CORE/Cake/Routing/Dispatcher.php, line 140]
Warning (4096): Argument 2 passed to Dispatcher::dispatch() must be an instance of CakeResponse, none given, called in /home/xxx/domains/xxx.com/public_html/xxx/v3/app/webroot/index.php on line 110 and defined [CORE/Cake/Routing/Dispatcher.php, line 140]
Notice (8): Trying to get property of non-object [CORE/Cake/Routing/Filter/AssetDispatcher.php, line 45]

我的 app / webroot / index.php 是（我只显示最后一部分）：

App::uses('Dispatcher', 'Routing');

$url = do_decrypt($_REQUEST["url"]); 
$Dispatcher = new Dispatcher(); 
$Dispatcher->dispatch($url);

$Dispatcher = new Dispatcher();
$Dispatcher->dispatch(
    new CakeRequest(),
    new CakeResponse()
);

Answer 1

在CakePHP 2.x中更改了CakePHP附带的.htaccess文件。它不再设置url变量，因此在$_REQUEST中不可用。相反，您可以使用$_SERVER['REQUEST_URI']来获取网址。然后必须将此URL传递给CakeRequest的构造函数。所以你的代码看起来像：

App::uses('Dispatcher', 'Routing');

$url = do_decrypt($_SERVER["REQUEST_URI"]); 
$Dispatcher = new Dispatcher();
$Dispatcher->dispatch(
    new CakeRequest($url),
    new CakeResponse()
);
