wheel部分有個小例子，代碼不貼了。

其中有幾行：

? ? ? ? # 告訴ReadLine監(jiān)控終端
?

? ? ? ? $console->get( 'input your message, bye to quit: ');
?

? ? ? ? $heap->{console} = $console;
?

原以為$console->get僅僅是終端輸出，所以在copy腳本的時候就刪掉了。結果怎么調代碼都不回顯，server端也收不到東西。

cpan上關于這個get函數(shù)的說明：

get

get() causes POE::Wheel::ReadLine to display a prompt and then wait for input. Input is not noticed unless get() has enabled the wheel's internal I/O watcher.

After get() is called, the next line of input or exception on the console will trigger an InputEvent with the appropriate parameters. POE::Wheel::ReadLine will then enter an inactive state until get() is called again.

Calls to get() without an argument will preserve the current prompt. Calling get() with an argument before a whole line of input is received will change the prompt on the fly.

悲催啊。。。。。
