解决方法 该列表中有两种不同的块. “可执行”块,包含可执行的perl代码,以及包含键值对的非可执行块(与perl哈希不同).

可执行块

<％一次>

This block is executed whenever the component is loaded into memory.
It is executed before any other block.

<％共享>

This block is executed once per request. It is executed before the <%init> block.

<％的init>

This block is executed every time the component is called. It is executed before any other code except for code in <%once> or <%shared> blocks.

不可执行块

<％ARGS>

This block is used to declare the arguments that a component expects.
In addition,it can also be used to specify a default value if none is
given when the component is called.

<％标志>

This block is used to declare special Mason flags,which are used to
affect the component’s behavior. Currently,there is only one flag
defined,inherit.

<％ATTR>

This block is used to declare arbitrary key-value pairs. Unlike the
<%flags> block,the contents are not used by Mason but may be used in
your code.
