删除ASCII颜色代码

本文介绍了删除ASCII颜色代码的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 所以，我遇到了问题。我从记录器中捕获了一些东西，输出看起来像这样：So, I'm having an issue. I'm catching some stuff from a Logger, And the output looks something like this:11:41:19 [INFO] ←[35;1m[Server] hi←[m我需要知道如何删除那些讨厌的ASCII颜色代码（或解析它们）。I need to know how to remove those pesky ASCII color codes (or to parse them).推荐答案如果它们完好无损，它们应该由ESC组成（ U + 001B ）加上 [加上以分号分隔的数字列表，再加上 m 。 （请参阅 https://stackoverflow.com/a/9943250/978917 。）在这种情况下，您可以删除它们写作：If they're intact, they should consist of ESC (U+001B) plus [ plus a semicolon-separated list of numbers, plus m. (See https://stackoverflow.com/a/9943250/978917.) In that case, you can remove them by writing:final String msgWithoutColorCodes = msgWithColorCodes.replaceAll("\u001B\\[[;\\d]*m", "");。 。 。或者您可以在检查日志时使用 less -r 来利用它们。 ： - ）. . . or you can take advantage of them by using less -r when examining your logs. :-)（注意：这是特定于颜色代码。如果你还找到其他ANSI转义序列，你会想要概括一点。我认为相当一般的正则表达式是 \\\\\ [[; \\\\] * * - - / * * [@ - 〜] 。你可能会发现 http://en.wikipedia.org/wiki/ANSI_escape_code 有用。）(Note: this is specific to color codes. If you also find other ANSI escape sequences, you'll want to generalize that a bit. I think a fairly general regex would be \u001B\\[[;\\d]*[ -/]*[@-~]. You may find http://en.wikipedia.org/wiki/ANSI_escape_code to be helpful.)如果序列不完好无损—也就是说，如果他们以某种方式受到损害—那么你将不得不调查并弄清楚究竟发生了什么错误。If the sequences are not intact — that is, if they've been mangled in some way — then you'll have to investigate and figure out exactly what mangling has happened. 这篇关于删除ASCII颜色代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
