我正在使用 Apache TelnetClient通过 telnet 进行连接,并希望将编码更改为纯文本。
在尝试处理VT100响应时,但是String
response 带有color。如何删除颜色编码以获取纯文本?
我最终得到如下片段(仅用于说明):
You say: confusing the hell out of bob.

INFO: You say: confusing the hell out of bob.

Sep 13, 2013 8:13:13 PM telnet.player.RegexWorker parseAndUpdatePlayerCharacter
INFO: say
问题在于 CSI 颜色代码随行而来。如何将String
编码从 VT100 转换为纯文本?
用于说明的Java代码示例:

/***
* This is an example of a trivial use of the TelnetClient class.
* It connects to the weather server at the University of Michigan,
* um-weather.sprl.umich.edu port 3000, and allows the user to interact
* with the server via standard input. You could use this example to
* connect to any telnet server, but it is obviously not general purpose

* inconvenient for use with a remote interactive shell. The TelnetClient
* class used by itself is mostly intended for automating access to telnet
* resources rather than interactive use.

但是,根据您连接到的服务器,响应不会是纯文本的 - 上面的代码仅用于说明目的,以显示ApacheTelnet
.
或者,是否可以将 Apache实例设置为仅通过该字段TelnetClient
接受纯文本?TERMINAL_TYPE
然而,这个领域是最终的......
困难在于在 VT100 彩色文本上运行正则表达式——你如何忽略颜色?或者,只使用纯文本字符串?
