ruby的生成隨機驗證碼

網上找的使用ruby生成的隨機驗證碼

require 'rubygems'
require 'rmagick'
class validationimage
include magick
attr_reader :code, :image
jiggle = 15
wobble = 15
def initialize(len = 4)
chars = ('a'..'z').to_a + ('0'..'9').to_a
rand_chars = 
1.upto(len) #生成驗證碼
background_type = "netscape:" #彩條 "granite:" #花崗岩 "xc:#edf7e7" #指定背景色 "null:" #純黑
background = magick::imagelist.new(background_type)  #背景畫布
canvas = magick::imagelist.new  #新建乙個畫布
canvas.new_image(32*len, 30, magick::texturefill.new(background)) #把背景加到畫布上
gc = magick::draw.new  #新建乙個畫筆
gc.font_family = 'times'
gc.pointsize = 20
cur = 10
#在畫布上把驗證碼寫上去？
rand_chars.each
cur += 30
}@code = rand_chars.to_s
@image = canvas.to_blob
endend
v=validationimage.new
#生成filename= file.new('c:\1.jpg',"w+")
filename.binmode
puts v.code
filename.puts v.image
filename.puts v.code
