在Zend框架2中的Controller-Action中获取GET参数的不同方法之间有什么区别？

Question

I found several ways to get GET parameters inside Controller > Action in Zend Framework 2 :

 $this->params()->fromRoute('id');

 $this->params('id');

 $this->getRequest()->getQuery()->get('id');

Is there any difference among these ways?

I guess, params('id') may give values from GET and POST both. fromRoute and getQuery will give value from GET only, but fromRoute may give some advantages like sanitation or something?

Answer 1

$this->params()->fromRoute('id');

This uses the params plugin and returns a single named route parameter. This is used for parameters in segment routes (eg 'slug' from /blog/:slug or 'year' from /archive/:year/:month/:day ).

$this->params('id');

This is just shorthand for $this->params()->fromRoute('id'); .

$this->getRequest()->getQuery()->get('id');

This grabs a value from the query string.
