本文实例展示了python生成验证码的方法，具有很好的实用价值。分享给大家供大家参考。具体实现方法如下：
前台页面代码如下：
看不清换一张
《script》
function refreshcode() {
$(‘authcode_img’).src = “/registration/makeimage/” + math.random();
}
《script》
后台程序如下：
import stringio
import image, imagedraw, imagefont, random #相应的模块需要安装
from xxx.settings import authcode_font #请确保改字体存在
def make_image(request):
mp = hashlib.md5()
mp.update(str(datetime.datetime.now())+str(random.random()))
mp_src = mp.hexdigest()
rand_str = mp_src[0:6]
font = imagefont.truetype(authcode_font, 25)
width = 75
height = 30
im = image.new(‘rgb’,(width,height),’#%s’%mp_src[-7:-1])
draw = imagedraw.draw(im)
draw.line((random.randint(0,width),random.randint(0,height),random.randint(0,width),random.randint(0,height)))
draw.line((random.randint(0,width),random.randint(0,height),random.randint(0,width),random.randint(0,height)))
draw.line((random.randint(0,width),random.randint(0,height),random.randint(0,width),random.randint(0,height)))
draw.line((random.randint(0,width),random.randint(0,height),random.randint(0,width),random.randint(0,height)))
draw.line((random.randint(0,width),random.randint(0,height),random.randint(0,width),random.randint(0,height)))
draw.text((5,2), rand_str, font=font)
del draw
buffer = stringio.stringio()
im.save(buffer,’jpeg’)
httpresponse = httpresponse(content=buffer.getvalue(),mimetype=”image/jpeg”)
request.session[‘auth_code’] = rand_str
return httpresponse
程序效果如下：
