问题描述

在Zend框架中重定向和转发之间有什么区别?

What is the difference between redirect and forward in Zend framework?

什么时候应该使用重定向，什么时候应该使用转发?

When we should use redirect and when should we use forward?

推荐答案

_forward()只是转发所有内容到另一个控制器操作，而_redirect()发送标头，这意味着您创建了一个新的HTTP请求并完成整个调度过程.

_forward() just forwards everything to another controller action, while _redirect() sends a header, meaning you create a new HTTP Request and go through the entire dispatch process with it.

例如，如果您调用 http://example.com/foo/bar ，您将调用foo控制器和bar动作.如果您将bar动作内部转发到baz动作，例如在相同的请求中，浏览器仍将使用相同的URL，而在进行重定向时，ZF会指示浏览器加载 http://example.com/foo/baz .

For instance, if you call up http://example.com/foo/bar you'd call the foo controller and bar action. If you forward inside the bar action to the baz action, e.g. within the very same request, the browser would still be on the same URL, while when doing a redirect, ZF would instruct the browser to load http://example.com/foo/baz.

基本上，_forward()可以

$request->setActionName($action)
        ->setDispatched(false);

而_redirect()确实

$this->_helper->redirector->gotoUrl($url, $options);

当我想防止重新加载页面导致重新发布表单数据时，我通常会进行重定向.

I usually do redirects when I want to prevent reload a page resulting in reposting form data.
