python3 之 天天生鲜 项目（初学者）3

用户模块

实现:

　　注册----登录    功能     验证

这里views.py使用类方法

from django.conf.urls import url
from users import views

urlpatterns = [
    url(r"^register", views.RigisterView.as_view(),name="register"),
]

class RigisterView(View):
    def get(self,request):
        return render(request,"register.html")
    def post(self,request):
        # 获取注册信息
        username = request.POST.get("user_name")
        password = request.POST.get("pwd")
        cpassword = request.POST.get("cpwd")
        email = request.POST.get("email")
        allow = request.POST.get("allow")
        # 数据处理 验证数据完整性
        if not all([username, password, cpassword, email, allow]):
            return render(request, "register.html", {"errmsg": "数据不完整"})
        # 验证密码是否一致
        if password != cpassword:
            return render(request, "register.html", {"errmsg": "密码不一致"})
        # 验证邮箱    # [w.-]+ 指一个或多个[w.-] 这样的字符，如 "aaa" "-ab" "c" "s._-l"
        if not re.match(r"^[a-z0-9][w.-]*@[a-z0-9-]+(.[a-z]{2,5}){1,2}$", email):
            return render(request, "register.html", {"errmsg": "邮箱格式不正确"})
        # 验证是否勾选协议
        if allow != "on":
            return render(request, "register.html", {"errmsg": "请同意协议"})
        # 验证用户名是否存在(这里使用不重复户用名)
        try:
            user = User.objects.get(username=username)
        except User.DoesNotExist:
            user = None  # 如果不存在 赋值为空
        if user:  # 如果存在
            return render(request, "register.html", {"errmsg": "用名已存在"})
        # 保存到数据库 mysql
        user = User.objects.create_user(username, email, password)
        user.is_active = False  # 0 也可以 邮箱未验证设置为0
        user.save()
        # 邮箱激活
        # 获取token
        token = user.gennerate_activeate_token()
        # 发送邮件
        celery_send_email.delay(email,token)
        return render(request, "login.html")

注册 ---------  功能    mysql.......celery.....redis........

这里使用    异步邮箱验证(celery)   前面有讲到 异步实现的方法  

    代理redis 库4的信息  

填写注册信息

mysql查看注册信息  

 收到激活链接

 接下来就是要实现邮箱验证  active  

from django.conf.urls import url
from users import views

urlpatterns = [
    url(r"^activate(?P<token>.+)/", views.activate,name="activate"),
]

from itsdangerous import TimedJSONWebSignatureSerializer as Serializer

def activate(request,token):
    serializer = Serializer(settings.SECRET_KEY,3600)  # 设置3600秒过期 
    try:
        json_str = serializer.loads(token)
    except:
        return HttpResponse("连接已过期")

    user_id = json_str["confirm"]try:
        user = User.objects.get(id=user_id)
    except User.DoesNotExist:
        return HttpResponse("账号存在异常")
    #邮箱验证通过 修改
    user.is_active = True
    user.save()

    return render(request,"login.html")

后期要用它来 登录验证
