這里一篇寫 注冊 登錄 用戶激活 這三個功能

Captcha 包的使用 驗證碼 關(guān)于captfcha的使用 我新寫了一篇 介紹簡單的使用 這一篇 有點雜了

captcha使用：http://www.itdecent.cn/p/a045ddae9144

首先 來 簡單的 登錄吧

LoginView

from django.shortcuts import render
from django.views import View
from django.contrib.auth import authenticate, login, logout
from django.http import HttpResponse, HttpResponseRedirect
from django.urls import reverse
from django.contrib.auth.views import get_user_model
from django.contrib.auth.hashers import make_password
from django.contrib.auth.backends import ModelBackend
from django.db.models import Q

from .models import UserProfile,EmailVerifyRecord
from .forms import LoginForm, RegisterForm
from utils.email_send import send_type_email

# 使用郵箱或用戶名登錄都行
class LoginView(View):
    def get(self, request):
        login_form = LoginForm()
        return render(request, "login.html", {'login_form': login_form})

    def post(self, request):
        login_form = LoginForm(request.POST)
        if login_form.is_valid():
            user_name = request.POST.get('username', "")
            password = request.POST.get('password', "")
            user = authenticate(username=user_name, password=password) #驗證用戶
            if user is not None:    #如果有這個用戶  就會取到這個用戶的信息
                if user.is_active:    # 判斷用戶是否 激活
                    login(request, user)                
                    return HttpResponseRedirect(reverse('index'))
                else:
                    return render(request, 'login.html', {"msg": "用戶未激活！"})
            else:
                return render(request, 'login.html', {"msg": "用戶名或者密碼錯誤！"})
        else:
            return render(request, 'login.html', {"login_form": login_form})

LoginForm 兩個字段 一個用戶名或郵箱 一個密碼字段

class LoginForm(forms.Form):
    username = forms.CharField(required=True)
    password= forms.CharField(min_length=5,required=True)

這里還有一個 就是我們要修改 django自帶的authenticated驗證 它自帶的 只能驗證username字段 我們希望 用戶使用email同樣可以登錄

所以 寫一個 驗證view

# 重寫驗證方法  他會自動來這里  使用這個驗證方法
class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = UserProfile.objects.get(Q(username=username) | Q(email=username))
            if user.check_password(password):
                return user
        except Exception as e:
            return None

就可以測試登錄了 附上簡單的html html太長了 就算了

ReigsterView

# 只能是用郵箱注冊
class RegisterView(View):
    def get(self, request):
        register_form = RegisterForm(request.POST)
        return render(request, 'register.html', {"register_form": register_form})

    def post(self, request):
        register_form = RegisterForm(request.POST)
        if register_form.is_valid():
            user_profile = UserProfile()
            user_name = request.POST.get('email', "")
            if UserProfile.objects.filter(username=user_name):
                return render(request, "register.html", {"register_form": register_form, "msg": "用戶已經(jīng)存在"})
            pass_word = request.POST.get('password', "")
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.password = make_password(pass_word)
            user_profile.is_active = False #默認(rèn)為未激活
            user_profile.save()

            send_type_email(user_name, "register")   #發(fā)送 郵件  讓用戶激活
            return render(request, 'login.html', {})
        else:
            return render(request, "register.html", {"register_form": register_form})

RegisterForm 這里引入了一個新東西 第三方包 驗證碼的使用

class RegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=5)
    captcha = CaptchaField(error_messages={"invalid": "驗證碼錯誤"})

關(guān)鍵來了 上面 注冊時 需要給用戶發(fā)送郵件 讓用戶激活

這里我們創(chuàng)一個 utils文件夾 來保存我們的 email_send.py 文件

# coding:utf-8
__author__ = "dfk"
__date__ = "2018/1/20 11:41"
from random import Random,choices
from django.core.mail import send_mail

from user.models import EmailVerifyRecord
from dj_game.settings import EMAIL_FROM


# 隨機字符串
def random_str(randomlength=8):
    str = ""
    chars = "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789"
    length = len(chars) -1
    random = Random()
    for i in range(randomlength):
        str += chars[random.randint(0,length)]
    return str

def send_type_email(email,send_type = 'register'):
    email_record  = EmailVerifyRecord()
    code = random_str(16)
    email_record.code = code
    email_record.email = email
    email_record.send_type = send_type
    email_record.save()      #保存code 和  email 用于 激活 認(rèn)證

    email_title =""
    email_body = ""

    if send_type == 'register':
        email_title = "小學(xué)生游戲網(wǎng)注冊激活鏈接"
        email_body = "請點擊下面的鏈接激活你的賬戶: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

同樣需要在settings中配置 email信息

#郵箱信息

EMAIL_HOST = "smtp.163.com"
EMAIL_PORT = 25
EMAIL_HOST_USER = "xxxx@163.com"
EMAIL_HOST_PASSWORD = '你的授權(quán)碼'   
EMAIL_USER_TLS = False
EMAIL_FROM = "xxxx@163.com"

這樣就可以測試注冊了

既然 說到了 激活 所以我們還要寫一個激活view來激活

激活 主要就是 發(fā)給用戶 一個 帶有code的鏈接 當(dāng)用戶 點擊這個連接時，我們拿到這個code和 我們數(shù)據(jù)庫中的email驗證 如果相同 就 激活用戶

# 激活
class ActiveUserView(View):
    def get(self, request, active_code):
        all_records = EmailVerifyRecord.objects.filter(code=active_code)
        if all_records:
            for record in all_records:
                email = record.email
                user = UserProfile.objects.get(email=email)
                user.is_active = True
                user.save()
        else:
            return render(request, 'active_fail.html')
        return render(request, 'login.html')

登出功能

LogouView

class LogoutView(View):
    def get(self, request):
        logout(request)
        return HttpResponseRedirect(reverse('index'))

注意配置urls 否則無法測試登錄 注冊功能

import xadmin
from django.conf.urls import url,include
from django.contrib import admin

from game.views import GamedetailView, GameIndexView, GamelistView
from user.views import LoginView, LogoutView, ActiveUserView, RegisterView

urlpatterns = [
    url(r'^xadmin/', xadmin.site.urls),
    #首頁
    url(r'^$', GameIndexView.as_view(), name='index'),
    #游戲列表
    url(r'^gamelist/(?P<tag_id>.*)/$', GamelistView.as_view(), name='gamelist'),
    #游戲詳情
    url(r'^games/(?P<game_id>.*)/$', GamedetailView.as_view(), name='games'),
    #登錄
    url(r'^login/$', LoginView.as_view(), name='login'),
    #注冊
    url(r'^register/$', RegisterView.as_view(), name='register'),
    #退出
    url(r'^logout/$', LogoutView.as_view(), name='logout'),
    #激活
    url(r'^active/(?P<active_code>.*)/$', ActiveUserView.as_view(), name='active'),
    #驗證碼相關(guān)url
    url(r'^captcha/', include('captcha.urls')),
]
