解析Ruby日志消息的正则表达式

Posted 2021-02-25

# parse ruby log message
# customize as needed
LOG_EXPRESSION = /([w]+),s+[([^]s]+)s+#([^]]+)]s+(w+)s+--s+(w+)?:s+(.+)/
 
# sample log output from this call:
#   logger.info("Ubiquitously") { "[dequeud] #{JSON.generate(params)}"}
string = 'I, [2010-08-15T16:16:46.142801 #81977]  INFO -- Ubiquitously: {"title":"Google","url":"google.com","tags":"search, google, api","services":["meta_filter","mixx"],"description":"a search engine!"}'
 
sample_output.gsub(LOG_EXPRESSION) do |match|
  severity  = $1
  date      = $2 # Time.parse(date)
  pid       = $3
  label     = $4
  app       = $5
  message   = $6
end
