# 位数

numbers= 4

# 验证码大小

size=( 150 , 60 )

# 背景颜色

bgcolor=( 255 , 255 , 255 )

# 字体颜色

fontcolor=( 0 , 0 , 0 )

#line 干扰线

draw_line= True

# 线数量范围

line_numbers=( 1 , 5 )

# 随机背景颜色

def bgfontrange():

global bgcolor

color1=random.randint( 0 , 255 )

color2 = random.randint( 0 , 255 )

color3 = random.randint( 0 , 255 )

fontcolor=(color1,color2,color3)

# 随机生成四个随机数 :

def make_text():

source1= [ str (x) for x in range ( 0 , 10 )] #0-9 之间

source2=[ "a" , "b" , "c" , "d" , "e" , "f" , "g" , "h" , "i" , "j" , "k" , "l" , "m" , "n" , "o" , "p" , "q" , "r" , "s" , "t" , "u" , "v" , "w" , "x" , "y" , "z" ]

return "" .join(random.sample(source,numbers)) #"", 加上 4 个随机数

# 随机划线

2.汉字随机生成:

# 背景颜色

bgcolor=( 255 , 255 , 255 )

# 字体颜色

fontcolor=( 0 , 0 , 0 )

#line 干扰线

draw_line= True

line_numbers=( 1 , 5 )

# 中文字符

class RandomChar():

# 方法一 :

@staticmethod

def Unicode():

val = random.randint( 0x4E00 , 0x9FA5 ) # 基本汉字的 unicode 编码范围 (0x4E00, 0x9FA5)

# 方法二

@staticmethod

return str
