Python 随机生成中文验证码的实例代码
python代码 复制代码 代码如下: # -*- coding: utf-8 -*- import Image,ImageDraw,ImageFont import random import math,string class RandomChar(): """用于随机生成汉字""" @staticmethod def Unicode(): val = random.randint(0x4E00,0x9FBF) return unichr(val) @staticmethod def GB2312(): head = random.randint(0xB0,0xCF) body = random.randint(0xA,0xF) tail = random.randint(0,0xF) val = ( head << 8 ) | (body << 4) | tail str = "%x" % val return str.decode('hex').decode('gb2312')
class ImageChar(): def __init__(self,fontColor = (0,0), size = (100,40), fontPath = 'wqy.ttc', bgColor = (255,255,255), fontSize = 20): self.size = size self.fontPath = fontPath self.bgColor = bgColor self.fontSize = fontSize self.fontColor = fontColor self.font = ImageFont.truetype(self.fontPath,self.fontSize) self.image = Image.new('RGB',size,bgColor) def rotate(self): self.image.rotate(random.randint(0,30),expand=0) def drawText(self,pos,txt,fill): draw = ImageDraw.Draw(self.image) draw.text(pos,font=self.font,fill=fill) del draw def randRGB(self): return (random.randint(0, random.randint(0,255)) def randPoint(self): (width,height) = self.size return (random.randint(0,width),random.randint(0,height)) def randLine(self,num): draw = ImageDraw.Draw(self.image) for i in range(0,num): draw.line([self.randPoint(),self.randPoint()],self.randRGB()) del draw
gap = 5 start = 0 for i in range(0,num): char = RandomChar().GB2312() x = start + self.fontSize * i + random.randint(0,gap) + gap * i self.drawText((x,random.randint(-5,5)),RandomChar().GB2312(),self.randRGB()) self.rotate() self.randLine(18) def save(self,path): self.image.save(path) 调用方法 复制代码 代码如下: ic = ImageChar(fontColor=(100,211,90)) ic.randChinese(4) ic.save("1.jpeg") (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
