Zend Framework 2 - Cookie Concept

Question

我衝浪了很多。我想用COOKIE分配和檢索一個值。我如何在ZF2中做？我看到了很多用於在cookie中分配值的示例。請解釋如何從cookie中檢索值。

Answer 1

在HTTP一個cookie（見RFC 2109簡單的東西存儲在請求和發送的每一個請求時的時間。一個響應可以添加其他參數可以另外保存到已經存在的Cookie。

所以餅乾檢索通過Request做的那樣，更新使用Response的cookie。根據RFC 2109，你分別用Cookie頭和Set-Cookie頭，你可以因此直接通過

訪問這些報頭個

$this->getRequest()->getHeaders()->get('Cookie')->foo = 'bar'; 

設置Cookie通過：

$this->getResponse()->getHeaders()->get('Set-Cookie')->foo = 'bar'; 

事情做了一個稍微容易一些，但因爲沒有在請求和響應的代理直接訪問的cookie：

public function fooAction() 
{ 
    $param = $this->getRequest()->getCookie()->bar; 

    $this->getResponse()->getCookie()->baz = 'bat'; 
} 

保持記住Cookie和Set-Cookie標頭實現了ArrayObject對象。要檢查一個cookie是否存在請求，你可以這樣使用offsetExists：

if ($cookie->offsetExists('foo')) { 
    $param = $cookie->offsetGet('foo'); 
} 

/更新：

如果要修改Cookie的屬性，你也在這裏修改Set-Cookie頭。對於所有可用的方法，請看at the class on Github。

輕微摘要：

$cookie = $this->getResponse()->getCookie(); 
$cookie->foo = 'bar'; 
$cookie->baz = 'bat'; 

$this->setDomain('www.example.com'); 
$this->setExpires(time()+60*60*24*30); 

Answer 2

該Cookie訪問通過$this->getResponse()->getCookie()的作品，但就是囉嗦而繁瑣。所以我做了什麼，我擴展了Response和Request類。這裏是什麼樣子：

'service_manager' => array (
    'factories' => array (
     'Request' => 'Application\Mvc\Request\Factory', 
     'Response' => 'Application\Mvc\Response\Factory', 
    ) 
); 

模塊/應用/ src目錄/應用/ MVC /申請/ Factory.php

namespace Application\Mvc\Request; 

use Zend\Console\Request as ConsoleRequest; 
use Zend\Console\Console; 
use Zend\ServiceManager\FactoryInterface; 
use Zend\ServiceManager\ServiceLocatorInterface; 

class Factory implements FactoryInterface 
{ 
    public function createService (ServiceLocatorInterface $serviceLocator) 
    { 
     if (Console::isConsole()) 
     { 
      return new ConsoleRequest(); 
     } 

     return new HttpRequest(); 
    } 
} 

模塊/應用/ src目錄/應用/ MVC /請求/ HttpRequest.php

namespace Application\Mvc\Request; 
use Zend\Http\PhpEnvironment\Request; 

class HttpRequest extends Request 
{ 
    public function hasCookie ($name) 
    { 
     assert ('is_string($name)'); 

     $cookie = $this->getCookie(); 
     if (empty ($cookie)) 
     { 
      return false; 
     } 

     if (isset ($cookie [$name])) 
     { 
      return true; 
     } 

     return false; 
    } 


    public function cookie ($name, $default = null) 
    { 
     assert ('is_string($name)'); 

     if ($this->hasCookie($name)) 
     { 
      $cookie = $this->getCookie(); 
      return $cookie [$name]; 
     } 

     return $default; 
    } 
} 

模塊/應用/ SRC /應用/ MVC /響應/ Factory.php

namespace Application\Mvc\Response; 

use Zend\Console\Response as ConsoleResponse; 
use Zend\Console\Console; 
use Zend\ServiceManager\FactoryInterface; 
use Zend\ServiceManager\ServiceLocatorInterface; 

class Factory implements FactoryInterface 
{ 
    public function createService (ServiceLocatorInterface $serviceLocator) 
    { 
     if (Console::isConsole()) 
     { 
      return new ConsoleResponse(); 
     } 
     return new HttpResponse(); 
    } 
} 

模塊/應用/ src目錄/應用/ MVC /響應/ HttpResponse.php

namespace Application\Mvc\Response; 

use Zend\Http\PhpEnvironment\Response; 
use Zend\Http\Header\SetCookie; 

class HttpResponse extends Response 
{ 
    public function addCookie ($name, $value, $expires = null, $path = null, $domain = null, $secure = false, $httponly = false, $maxAge = null, $version = null) 
    { 
     $cookie = new SetCookie ($name, $value, $expires, $path, $domain, $secure, $httponly, $maxAge, $version); 
     $this->getHeaders() 
      ->addHeader ($cookie); 
    } 
} 

現在，我享受餅乾更容易訪問。

$this->getRequest()->cookie ('ptime'); 
$this->getRequest()->cookie ('alarm', 'last'); 

和

$this->getResponse()->addCookie ('ptime', time());
