我知道 symfony api 解释说 getMethod() 获取请求预期"方法，而 getRealMethod() 获取真实"请求方法，但我无法弄清楚预期"和真实"是什么意思.谁能告诉我?谢谢

I know the symfony api explain that getMethod() gets the request "intended" method and getRealMethod() gets the "real" request method but i can't figure out what "intended" and "real" means. Can anyone tell me? Thanks

推荐答案

getRealMethod() 返回真实请求方法，而 getMethod()> 返回预期的请求方法，这意味着真正的请求方法是POST，但symfony将其他方法视为DELETE.

getRealMethod() returns the real request method, while getMethod() returns the intended request method, which means the real request method is POST but symfony treat as others like DELETE.

请看下面的例子:

<form method="post" action="..." > <input type="hidden" name="_method" value="DELETE" /> ... </form>

真正的请求方法是POST，而getMethod()会返回DELETE.

The real request method is POST, while getMethod() will return DELETE.
