今天完成的是用户注册功能...
首先把注册页面的前端文件register.html复制到templates目录下
编辑users.views.py,创建一个注册的类
class RegisterView(View):
def get(self, request):
return render(request, 'register.html', {})
配置注册页面的url
...
from users.views import LoginView, RegisterView
urlpatterns = [
#url(r'^admin/', admin.site.urls),
url(r'^xadmin/', xadmin.site.urls),
url(r'^$', TemplateView.as_view(template_name='index.html'), name='index'),
url(r'^login/$', LoginView.as_view(), name='login'),
url(r'register/$', RegisterView.as_view(), name='register'),
]
【新知识点--静态文件】替换注册页面的静态文件路径，这里我们不用之前的替换方法，而是使用Django提供的
【新知识点-url】修改首页index.html ‘注册’和‘登录’的超链接
【验证码】用户注册我们需要用到一个功能就是验证码
要使用验证码，就需要安装一个验证码开发库，这里我们使用django-simple-captcha
workon mxonline pip install django-simple-captcha
编辑settings.py添加captcha到INSTALLED_APPS
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'users',
'courses',
'organization',
'operation',
'xadmin',
'crispy_forms',
'captcha',
]
配置一条url
from django.conf.urls import url, include
...
urlpatterns = [
#url(r'^admin/', admin.site.urls),
url(r'^xadmin/', xadmin.site.urls),
url(r'^$', TemplateView.as_view(template_name='index.html'), name='index'),
url(r'^login/$', LoginView.as_view(), name='login'),
url(r'register/$', RegisterView.as_view(), name='register'),
url(r'^captcha/', include('captcha.urls')),
]
同步数据表
manage.py@mxonline > makemigrations manage.py@mxonline > migrate
编辑users.forms.py配置表单验证
from captcha.fields import CaptchaField
class RegisterForm(forms.Form):
email = forms.EmailField(required=True)
password = forms.CharField(required=True, min_length=5)
captcha = CaptchaField()
编辑users.views.py
...
from .forms import LoginForm, RegisterForm
class RegisterView(View):
def get(self, request):
register_form = RegisterForm()
return render(request, 'register.html', {'register_form': register_form})
修改register.html
启动服务，看看注册页面
查看数据库，可以发现验证码表已经生成了记录
继续写注册逻辑，当用户提交注册，对验证码进行验证。这里打个断点调试，故意输错验证码
可以看到错误信息"认证码错误"， 我们也可以改成自己想要的信息(改成 验证码错误)，编辑users.forms.py
class RegisterForm(forms.Form):
email = forms.EmailField(required=True)
password = forms.CharField(required=True, min_length=5)
captcha = CaptchaField(error_messages={'invalid': '验证码错误'})
再次断点调试，已经变成我们自定义的信息了
继续注册流程编码
from django.contrib.auth.hashers import make_password
class RegisterView(View):
def get(self, request):
register_form = RegisterForm()
return render(request, 'register.html', {'register_form': register_form})
def post(self, request):
register_form = RegisterForm(request.POST)
if register_form.is_valid():
user_name = request.POST.get('email', '')
pass_word = request.POST.get('password', '')
user_profile = UserProfile() #实例化数据比哦啊
user_profile.username = user_name
user_profile.email = user_name
user_profile.password = make_password(pass_word) #对明文密码进行加密处理
user_profile.save() #保存到数据表
else:
return render(request, 'register.html', {'register_form': register_form})
[邮箱激活]我们使用邮箱注册，就涉及到发送邮件激活
发送邮件需要发送者，我们需要再settings.py中配置（末尾添加如下代码）
EMAIL_HOST = 'smtp.sina.com' EMAIL_PORT = 25 EMAIL_HOST_USER = 'xxxx@sina.com' EMAIL_HOST_PASSWORD = 'xxxxx' EMAIL_USE_TLS = False EMAIL_FROM = xxxx@sina.com'
因此需要写一个邮件基础函数
在apps目录下新建一个Python Package命名为utils，把它专门用来存放一些基础函数
在utils下新建email_send.py
from random import Random
from django.core.mail import send_mail
from users.models import EmailVerifyRecord
from mxonline.settings import EMAIL_FROM
def random_str(randomlength=8):
"""生成随机字符"""
str = ''
chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
length = len(chars) - 1
random = Random()
for i in range(randomlength):
str += chars[random.randint(0, length)]
return str
def sendEmail(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()
if send_type == 'register':
email_title = '慕学在线网激活链接'
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
编辑注册后台逻辑，发送邮件
...
from utils.email_send import sendEmail
class RegisterView(View):
def get(self, request):
register_form = RegisterForm()
return render(request, 'register.html', {'register_form': register_form})
def post(self, request):
register_form = RegisterForm(request.POST)
if register_form.is_valid():
user_name = request.POST.get('email', '')
pass_word = request.POST.get('password', '')
user_profile = UserProfile() #实例化数据比哦啊
user_profile.username = user_name
user_profile.email = user_name
user_profile.password = make_password(pass_word) #对明文密码进行加密处理
user_profile.is_active = False #处于未激活状态
user_profile.save() #保存到数据表
sendEmail(user_name, 'register')
return render(request, 'login.html')
else:
return render(request, 'register.html', {'register_form': register_form})
下面可以进行注册调试了，进去注册页面用邮箱进行注册,去查看邮箱（如果没有，请注意垃圾箱）
查看数据库
如果邮箱和密码不满足条件，form验证失败了，我也和之前login一样，提示给用户，register.html
[用户未激活]
正常情况下，我们刚刚注册的账号没有激活是无法登陆的，所以下我们还需要修改下登录逻辑，只有激活后的账号才能登录
class LoginView(View):
def get(self, request):
return render(request, 'login.html', {})
def post(self, request):
Login_form = LoginForm(request.POST)
if Login_form.is_valid():
user_name = request.POST.get('username', '')
pass_word = request.POST.get('password', '')
user = authenticate(username=user_name, password=pass_word)
if user is not None:
if user.is_active:
login(request, user)
return render(request, 'index.html')
else:
return render(request, 'login.html', {'msg':'用户未激活'})
else:
return render(request, 'login.html', {'msg': '用户名或密码错误'})
else:
return render(request, 'login.html', {'login_form': Login_form})
现在再尝试用刚刚注册的账号登录，无法登陆成功，提示用户未激活
【账号激活】
现在来完成激活功能，编辑users.views.py，创建一个用于激活的类
class ActiveUserView(View):
def get(self, request, active_code): #active_code是url传过来的参数
pass
配置url
...
from users.views import LoginView, RegisterView, ActiveUserView
urlpatterns = [
#url(r'^admin/', admin.site.urls),
url(r'^xadmin/', xadmin.site.urls),
url(r'^$', TemplateView.as_view(template_name='index.html'), name='index'),
url(r'^login/$', LoginView.as_view(), name='login'),
url(r'register/$', RegisterView.as_view(), name='register'),
url(r'^captcha/', include('captcha.urls')),
url(r'^active/(?P<active_code>.*)/$', ActiveUserView.as_view(), name='user_active'),
]
现在断点调试，点击之前发送的激活邮件链接http://127.0.0.1:8000/active/04tMGcH7lPqsgG5G
active_code已经接收到了激活码，现在我们只需要把激活码取出来，然后去数据中查询，如果匹配上了，就把对应的用户激活
from .models import UserProfile, EmailVerifyRecord
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()
return render(request, 'login.html')
现在点击激活链接，就可以激活成功，跳转登录页面，然后账号就可以成功登录了
