为什么在 grails 中转发和重定向不会停止初始动作的执行? [英] Why forward and redirect in grails don't stop initial action execution?

问题描述

我了解了 forward 和 redirect 在 Grails 中，不明白为什么下面的代码会打印foo".

I read about forward and redirect in Grails and don't understant why the code bellow prints "foo".

见:

def bar = {
   redirect (controller: "public", action: "index") // same happens with forward
   println "foo" // prints this in console?? WHY?
}

在我看来重定向/转发必须跳过当前方法的执行...

In my opinion redirect/forward must skip current method execution...

这是错误还是我理解错误?

Is this a bug or I understand the concept wrong?

推荐答案

因为这些是 只是函数调用 - 他们不能从调用函数(您的操作)中退出.只需将 return 放在后面即可.

Because these are just function calls - they can't exit from a calling function (your action). Just put return afterwards.
