登录页面设计

在login.html中

{% csrf_token %} ##注意form，注意action就是当前页面，method是post还是get将触发后台的动作，整个form由submit来触发。 ##注意{% csrf_token %}。django默认启动 'django.middleware.csrf.CsrfViewMiddleware'中间件， 这个中间件就是来验证csrf_token的。如果没有加csrf_token，就会出错。 在view.py中 def login(request): loginfo = data_gen.login() userid = 0 userkey = 0 global qxpro global qxfunc if request.method == "POST": userid = request.POST.get("uid") userkey = request.POST.get("ukey") if (userid==loginfo.user01[0][0] and userkey==loginfo.user01[0][1]): qxpro = loginfo.user01[1] qxfunc = loginfo.user01[2] response = HttpResponseRedirect('/index/') response.set_cookie("username", 'kdkj') return response elif (userid==loginfo.user02[0][0] and userkey==loginfo.user02[0][1]): qxpro = loginfo.user02[1] qxfunc = loginfo.user02[2] response = HttpResponseRedirect('/index/') response.set_cookie("username", 'shzf') return response return render(request, 'login.html') 在data_gen中 class login(): user01 = (('kdkj','123456'),(1,1,1,0,0),(1,1,1,1,1,1,1,1,1)) user02 = (('shzf', 'shzf'), (1, 1, 0, 0, 0), (1, 1, 1, 0, 0, 0, 1, 0, 0)) ###eb\pd\ac\gl\pv\es\tf\dd def __str__(self): return self.ID ###在类login中建立用户账号和权限 # 用户权限配置 View.Py： def login(request): loginfo = basic.log() username = 0 userkey = 0
