用户登录机制(找回密码)

用户登录机制(找回密码)

一、渲染过程

1.urls.py文件

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url('^$',TemplateView.as_view(template_name="index.html"),name='index'),
    url(r'^login/$',views.User_login.as_view(),name='login' ),
    url(r'^reg/$',views.User_reg.as_view(),name='reg' ),
    url(r'^active/(?P<acctive_code>.*)/$',views.AciveUserView.as_view(),name='user_active'),
    url(r'^forget/$',views.ForgetPwdView.as_view(),name='forget_pwd'), #用户忘记密码url
]

2.forms.py文件

class ForgetForm(forms.Form):

    email = forms.EmailField(required=True)
    captcha = CaptchaField(error_messages={"invalid":"验证码错误"})  #直接引用

3.views.py文件

class ForgetPwdView(View):
	def get(self,request):
		forget_form = forms.ForgetForm()
		return  render(request,'forgetpwd.html',{"forget_form":forget_form})

4.前端渲染的效果如图所示

二、重置过程

1.email_send.py文件

def random_str(randomlength=8):
    str = ''
    chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz123456789'
    lengh = len(chars) - 1
    random = Random()
    for i in range(randomlength):
        str+=chars[random.randint(0,lengh)]
    return str
def send_register_email(email,send_type="register"):
    print("进去邮箱")
    email_record = EmailVerifyRecord()
    code =random_str(16)
    email_record.code = code
    email_record.email =email
    email_record.send_type = send_type
    email_record.save()

    ###发送邮件###
    email_title = "" #邮件的title
    email_body = "" #邮件的正文

    if send_type == "register":

        email_title = "苹果官网注册激活链接"
        email_body = "请点击下面的链接激活你的账号：http://127.0.0.1:8000/active/{0}".format(code)

        send_status = send_mail(email_title,email_body,EMAIL_FROM,[email])
        if send_status:
            pass
    elif send_type == "forget":  #用户忘记密码
        email_title = "苹果官网重置密码链接"
        email_body = "请点击下面的链接重置你的密码：http://127.0.0.1:8000/reset/{0}".format(code)
        send_status = send_mail(email_title,email_body,EMAIL_FROM,[email])
        if send_status:
            pass

2.views.py文件

class ForgetPwdView(View):
	def get(self,request):
		forget_form = forms.ForgetForm()
		return  render(request,'forgetpwd.html',{"forget_form":forget_form})
	def post(self,request):
		forget_form = forms.ForgetForm(request.POST)
		if forget_form.is_valid():
			email = request.POST.get("email",'')
			send_register_email(email,'forget')  #发送重置密码邮件
			return render(request,'send_success.html') #该页面用于提示用户邮件发送成功
		else:
			return  render(request,'forgetpwd.html',{"forget_form":forget_form})

###用来验证邮箱后处理的视图函数####


class ResetView(View):
	def get(self,request,active_code):
		all_records = models.EmailVerifyRecord.objects.filter(code=active_code)
		if all_records:
			for record in all_records:
				email = record.email  #查找到验证码
				return render(request,'pasword_reset.html',{"email":email}) #传email的可以判断是哪个用户重置密码需要在前端渲染一个隐藏的input框

		return render(request,'login.html')

####post提交####

class ModifypwdView(View):
	def post(self,request):
		modify_form = forms.ModifyPwdForm(request.POST)
		if modify_form.is_valid():
			pwd1 = request.POST.get("password1",'')
			pwd2 = request.POST.get("password2",'')
			email = request.POST.get("email","")
			if pwd1 != pwd2:
				return render(request,"password_reset.html",{"email":email,"msg":"密码不一致"})
			user = models.Userinfo.objects.get(email=email)
			user.password = make_password(pwd2)
			user.save()
			return render(request,'login.html')
		else:
			email = request.POST.get("email",'')
			return render(request,"password_reset.html",{"email":email,'modify_form':modify_form})

3.urls.py文件

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url('^$',TemplateView.as_view(template_name="index.html"),name='index'),
    url(r'^login/$',views.User_login.as_view(),name='login' ),
    url(r'^reg/$',views.User_reg.as_view(),name='reg' ),
    url(r'^active/(?P<acctive_code>.*)/$',views.AciveUserView.as_view(),name='user_active'),
    url(r'^forget/$',views.ForgetPwdView.as_view(),name='forget_pwd'), #用户忘记密码url
    url(r'^reset/(?P<acctive_code>.*)/$',views.AciveUserView.as_view(),name='user_reset'), #用来处理邮箱验证后的重置url
	url(r'^modify_pwd/$',views.ModifyPwdView.as_view(),name='modify_pwd')  #用来处理邮箱验证中的POST提交的url
]

4.前端页面

前端页面需要注意的url
