django注册用邮箱发送验证码的实现

lis = []#设置一个空列表用来存放发送的验证码，用来验证
def yzm1():
    res1 = ""
    for i in range(4):#用四个随机数组成验证码
        num = random.randint(0, 9)
        res1 += str(num)
    lis.append(res1)#将验证码放入空的列表中
    return res1#返回验证码
class zc(View):
    def get(self, request):
        return render(request, 'zc.html', locals())
    def post(self, request):
        name = request.POST['qq']#获取前端传递进来的数据
        subject = '验证码'
        message = vercode()#获取验证码
        form = '837620306@qq.com'#获取发送验证码的邮箱
        # EMAIL_HOST_USER
        rcipient_list = [name]
        res = send_mail(subject=subject, message=message, from_email=form, recipient_list=rcipient_list)#发送验证码返货真或假，假代表没有发送成功
        if res == 1:#判断是否发送成功
            return redirect('/app01/yzm/')#成功的话跳转到验证的网页
        else:#不成功的话返回注册界面
            return render(request, 'zc.html', locals())
def yzm2(request):
    if request.method == 'GET':
        return render(request, 'yzm.html', locals())
    elif request.method == 'POST':
        a = request.POST['much']#获取到用户输入的验证码
        if a == lis[-1]:#取最新的验证码
            return HttpResponse('验证码正确')
        else:
            return HttpResponse('no')
