我有一段文本:
str_encode = "MTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTEx\nMTExMTExMTExMTExMQ==\n"
?想替换其中的"\n"为"\r\n",就是把<LF>全局替换为<CRLF>
?
代码如下:
irb(main):037:0> m = a.gsub(/\n/, "\r\n")=> "MTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTEx\r\nMTExMTExMTExMTExMQ==\r\n"
?
-------------------------------------------------万恶的分割线-------------------------------------------------------------------
另附错误替换示例
irb(main):038:0> m = a.gsub(/\n/, '\r\n')
?这个错误代码中将"\n"替换成"\\r\\n"
结果如下：
=> "MTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTEx\\r\\nMTExMTExMTExMTExMQ==\\r\\n"
?打印结果如下：
irb(main):039:0> puts mMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTExMTEx\r\nMTExMTExMTExMTExMQ==\r\n=> nil
?
