使用Hubot從Slack查詢MYSQL; CoffeeScript不起作用

我對CoffeeScript沒有任何經驗，所以如果過於簡單，我會提前道歉。以下是腳本。我試圖使用鬆弛，以便我可以鍵入mysql配置文件，它會查詢並返回結果。使用Hubot從Slack查詢MYSQL; CoffeeScript不起作用

# Description: 
# Profile a MySQL Query 
# 
# Notes: 
# This script requires a MySQL user with SELECT priviliges. 
# You can create a user like so: GRANT SELECT ON some_db.* TO 'hubot_mysql'@'hubot_host' IDENTIFIED BY 'some_pass'; 
# !! Warning. In order to collect a profile the query is executed. It is very strongly recommended that you use a read only user on a MySQL slave !! 
# 
# Dependencies: 
# "cli-table" : "https://github.com/LearnBoost/cli-table" 
# "mysql"  : "https://github.com/felixge/node-mysql" 
# "validator" : "https://github.com/chriso/validator.js" 
# 
# Configuration: 
# HUBOT_MYSQL_CHATOPS_HOST = localhost 
# HUBOT_MYSQL_CHATOPS_DATABASE = removed 
# HUBOT_MYSQL_CHATOPS_USER = removed 
# HUBOT_MYSQL_CHATOPS_PASS = removed 
# 
# Commands: 
# hubot mysql profile <sql> - Run MySQL profile on <sql> 

mysql = require 'mysql' 
table = require 'cli-table' 
validator = require 'validator' 

module.exports = (robot) -> 

    robot.respond /mysql profile (.*)/i, (msg) -> 
    msg.reply "This will run and profile a query against MySQL. To run this fo realz use mysql profile!. Be careful ;)" 
    return 

    robot.respond /mysql profile! (.*)/i, (msg) -> 
    query = validator.blacklist(msg.match[1], [';']) 

    unless process.env.HUBOT_MYSQL_CHATOPS_HOST? 
     msg.reply "Would love to, but kind of missing HUBOT_MYSQL_CHATOPS_HOST!" 
     return

     return

    @client.on 'error', (err) -> 
     robot.emit 'error', err, msg 

    @client.query "SET PROFILING = 1", (err, results) => 
     if err 
     msg.reply err 
     return 
     @client.query "#{query}", (err, results) => 
     if err 
      msg.reply err 
      return 
     @client.query "SHOW PROFILE FOR QUERY 1", (err, results) => 
      if err 
      msg.reply err 
      return 

      status_max = 0 
      duration_max = 0 

      rows = [] 

      for row in results 
      profile = ["#{row.Status}", "#{row.Duration}"] 
      padding = 8 
      if profile[0].length + padding > status_max 
       status_max = profile[0].length + padding 
      if profile[1].length + padding > duration_max 
       duration_max = profile[1].length + padding 
      rows.push profile 

      @grid = new table 
      head: ['Status', 'Duration (secs)'] 
      style: { head: false } 
      colWidths: [status_max, duration_max] 

      for row in rows 
      @grid.push row 

      msg.reply "\n#{@grid.toString()}" 
      @client.destroy()

在鬆弛的輸出：

This will run and profile a query against MySQL. To run this fo realz use mysql profile!. Be careful ;)

TL; DR;你很近！但我認爲你需要使用mysql profile!命令。

基於the hubot docs，看來你的代碼是否正常工作。

眼下This will run and profile...回調響應命令mysql profile。爲了實際調用執行你的MySQL查詢的回調，你需要用mysql profile!開始你的消息（注意尾部感嘆號）。
