一、登陆功能（验证码）
1 from geetest import GeetestLib 2 from django.contrib import auth 3 4 #使用极验滑动验证码的登陆 5 def login(request): 6 if request.method == "POST": 7 #初始化一个返回给ajax的字典 8 ret = {"status":0,"msg":""} 9 #从提交的数据中获取用户名和密码 10 username = request.POST.get("username") 11 password = request.POST.get("password") 12 #获取验证码相关数据 13 gt = GeetestLib(pc_geetest_id, pc_geetest_key) 14 challenge = request.POST.get(gt.FN_CHALLENGE, ‘‘) 15 validate = request.POST.get(gt.FN_VALIDATE, ‘‘) 16 seccode = request.POST.get(gt.FN_SECCODE, ‘‘) 17 status = request.session[gt.GT_STATUS_SESSION_KEY] 18 user_id = request.session["user_id"] 19 20 if status: 21 result = gt.success_validate(challenge, validate, seccode, user_id) 22 else: 23 result = gt.failback_validate(challenge, validate, seccode) 24 25 #如果result有值，则验证成功,利用auth做验证 26 if result: 27 user = auth.authenticate(username=username,password=password) 28 if user: 29 #如果用户名密码正确 30 auth.login(request,user) 31 ret["msg"] = "/index/" 32 else: 33 ret["status"] = 1 34 ret["msg"] = "用户名密码错误" 35 else: 36 #如果验证吗错误 37 ret["status"] = 1 38 ret["msg"] = "验证码错误" 39 return JsonResponse(ret) 40 return render(request,"login.html",locals()) 41 42 #请在官网申请ID使用，示例ID不可使用 43 pc_geetest_id = "b46d1900d0a894591916ea94ea91bd2c" 44 pc_geetest_key = "36fc3fe98530eea08dfc6ce76e3d24c4" 45 46 #获取滑动验证码 47 def get_geetest(request): 48 user_id = ‘test‘ 49 gt = GeetestLib(pc_geetest_id, pc_geetest_key) 50 status = gt.pre_process(user_id) 51 request.session[gt.GT_STATUS_SESSION_KEY] = status 52 request.session["user_id"] = user_id 53 response_str = gt.get_response_str() 54 return HttpResponse(response_str)

二、注册功能（ajax上传数据）
1 def register(request): 2 if request.method == "POST": 3 form_obj = RegisterForm(request.POST) 4 ret = {"status": 0, "msg": ""} 5 if form_obj.is_valid(): 6 form_obj.cleaned_data.pop("re_pwd") 7 avatar = request.FILES.get("avatar") 8 models.UserInfo.objects.create(**form_obj.cleaned_data,avatar=avatar) 9 return JsonResponse(ret) 10 else: 11 ret["status"] = 1 12 ret["msg"] = form_obj.errors 13 return JsonResponse(ret) 14 form_obj = RegisterForm() 15 return render(request,"register.html",locals())
