推荐答案

您可以真正使用两种。一般来说，虽然形式发布后，你想，这样刷新页面不会导致形式重新发布重定向。但是，有时它不是状态复制到新的页面可行的，你的处理幂这样刷新就不会伤害任何东西。

You can really use either. Generally speaking, though, after a form is posted you want to redirect so that refreshing the page doesn't cause the form to repost. Sometimes, however, it's not feasible to copy state to the new page and your processing is idempotent so refresh wouldn't hurt anything.

这并不是说有一个坚硬和快速的规则。你有种必须权衡的利弊和得失。

It's not that there's a hard-and-fast rule. You kind of have to weigh the pros and the cons.
