(Note: If you getattempt to concatenate a boolean valueas a response, then it's likely you haven't set thename:firstkey to a value). So now, in a script, we've taken a parameter, looked up a key's value and created a string and returned that as a result. This EVAL command is...

Lua中有8个基本类型分别为:nil、boolean、number、string、userdata、function、thread和table。数据类型描述 nil 这个最简单,只有值nil属于该类,表示一个无效值(在条件表达式中相当于false)。 boolean 包含两个值:false和true。 number 表示双精度类型的实浮点数 string 字符串由一对双引号或单引号来表示 function ...
