  这并不难：

  (                   # Start of group
      (?=.*\d)        #   must contain at least one digit
      (?=.*[A-Z])     #   must contain at least one uppercase character
      (?=.*[a-z])     #   must contain at least one lowercase character
      (?=.*\W)        #   must contain at least one special symbol
      \w
         .            #   match anything with previous condition checking
          {6,18}      #   length is  characters
      \w 
  )                   # End of group
  

  在一行中：

  ((?=.*\d)(?=.*[A-Z])(?=.*[a-z])(?=.*\W)\w.{6,18}\w)
  

  如果您不喜欢 \w 等于 [a-zA-Z0-9_] ，请将其替换为该组并删除下划线 .

  但是，我完全支持ctwheels的论点 .
