完成登录 注册 找回密码 激活 验证码集成
将HTML文件拷贝到templates目录下,css,js,img,media,images文件夹拷贝到static文件夹下
QQ截图20180907104837.png
修改index.html和login.html文件中的静态文件路径,全部替换为如下格式
<link rel="stylesheet" type="text/css" href="{% static "css/reset.css" %}">
<link rel="stylesheet" type="text/css" href="{% static "css/animate.css" %}">
<link rel="stylesheet" type="text/css" href="{% static "css/style.css" %}">
在文件最上方加入
{% load staticfiles %}
配置主页面的路由
urlpatterns = [
path('admin/', xadmin.site.urls),
path('',TemplateView.as_view(template_name='index.html'), name='index'),
]
配置登陆页面的路由
path('login/',LoginView.as_view(),name = 'login'),
编写登陆的逻辑代码
users/views.pu
# 实现用户名邮箱均可登录
# 继承ModelBackend类，因为它有方法authenticate，可点进源码查看
from users.models import UserProfile
class CustomBackend(ModelBackend):
def authenticate(self, username=None, password=None, **kwargs):
try:
# 不希望用户存在两个，get只能有一个。两个是get失败的一种原因 Q为使用并集查询
user = UserProfile.objects.get(Q(username=username)|Q(email=username))
# django的后台中密码加密：所以不能password==password
# UserProfile继承的AbstractUser中有def check_password(self, raw_password):
if user.check_password(password):
return user
except Exception as e:
return None
class LoginView(View):
def get(self,request):
return render(request, 'login.html')
def post(self,request):
# 获取用户提交的用户名和密码
user_name = request.POST.get('username', None)
pass_word = request.POST.get('password', None)
# 成功返回user对象,失败None
user = authenticate(username=user_name, password=pass_word)
# 如果不是null说明验证成功
if user is not None:
# 登录
login(request, user)
return render(request, 'index.html')
else:
return render(request, 'login.html', {'msg': '用户名或密码错误'})
在settings.py中启用自定义验证
# 自定义登陆验证
AUTHENTICATION_BACKENDS = (
'users.views.CustomBackend',
)
修改login文件中的form表单
QQ截图20180907113957.png
访问http://127.0.0.1:8000/login/即可进行登陆,成功会跳转到主页面,失败则会显示错误信息
QQ截图20180907142801.png
form实现登陆
在users目录下新建一个forms.py的文件
from django import forms
# 登录表单验证
class LoginForm(forms.Form):
# 用户名密码不能为空
username = forms.CharField(required=True)
password = forms.CharField(required=True, min_length=6)
修改LoginView的内容
def post(self, request):
# 类实例化需要一个字典参数dict:request.POST就是一个QueryDict所以直接传入
# POST中的username,password，会对应到form中
login_form = LoginForm(request.POST)
# is_valid判断我们字段是否有错执行我们原有逻辑，验证失败跳回login页面
if login_form.is_valid():
# 取不到时为空，username，password为前端页面name值
user_name = request.POST.get("username", "")
pass_word = request.POST.get("password", "")
# 成功返回user对象,失败返回null
user = authenticate(username=user_name, password=pass_word)
# 如果不是null说明验证成功
if user is not None:
# 账号是否激活
if user.is_active:
# login 两参数：request, user
# 实际是对request写了一部分东西进去，然后在render的时候：
# request是要render回去的。这些信息也就随着返回浏览器。完成登录
login(request, user)
# 跳转到首页 user request会被带回到首页
return render(request, "index.html")
else:
return render(request, "login.html", {"msg": "用户未激活！"})
# 验证不成功跳回登录页面
# 没有成功说明里面的值是None，并再次跳转回主页面
else:
return render(request, "login.html", {"msg": "用户名或密码错误! "})
# form.is_valid（）已经判断不合法了，所以这里不需要再返回错误信息到前端了,错误信息包含在form.errors中
else:
return render(request,'login.html',{'login_form':login_form})
修改login.html文件内容
QQ截图20180907195000.png
<div class="form-group marb20 {% if login_form.errors.username %}errorput{% endif %}">
<label>用 户 名</label>
<input name="username" id="account_l" type="text" placeholder="手机号/邮箱" />
</div>
<div class="form-group marb8 {% if login_form.errors.username %}errorput{% endif %}">
<label>密 码</label>
<input name="password" id="password_l" type="password" placeholder="请输入您的密码" />
</div>
<div class="error btns login-form-tips" id="jsLoginTips">
{% for key,error in login_form.errors.items %}
{{ error }}
{% endfor %}
{{ msg }}
</div>
使用admin账号进行登陆测试
邮箱注册
注册时需要验证码
这里使用插件 django-simple-captcha
pip install django-simple-captcha
配置到INSTALLED_APPS中
INSTALLED_APPS = [
...,
'captcha',
]
配置路由
path('captcha/',include('captcha.urls')),
映射到数据库
python manage.py makemigrations
python manage.py migrate
创建一个注册的form
# 引入验证码field
from captcha.fields import CaptchaField
# 验证码form & 注册表单form
class RegisterForm(forms.Form):
# 此处email与前端name需保持一致。
email = forms.EmailField(required=True)
# 密码不能小于5位
password = forms.CharField(required=True, min_length=5)
# 应用验证码
captcha = CaptchaField(error_messages={'invalid': '验证码错误'})
编写注册的逻辑代码
class RegisterView(View):
'''用户注册'''
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', None)
# 如果用户已存在，则提示错误信息
if UserProfile.objects.filter(email = user_name):
return render(request, 'register.html', {'register_form':register_form,'msg': '用户已存在'})
pass_word = request.POST.get('password', None)
# 实例化一个user_profile对象
user_profile = UserProfile()
user_profile.username = user_name
user_profile.email = user_name
user_profile.is_active = False
# 对保存到数据库的密码加密
user_profile.password = make_password(pass_word)
user_profile.save()
send_register_eamil(user_name,'register')
return render(request,'login.html',{"msg":"邮件已发送,进入邮箱激活"})
else:
return render(request,'register.html',{'register_form':register_form})
修改register.html文件
首先修改静态文件路径,接着修改表单配置
TIM截图20180908113139.png
<form id="email_register_form" method="post" action="/register/" autocomplete="off">
<div class="form-group marb20 {% if register_form.errors.email %}errorput{% endif %}">
<label>邮 箱</label>
<input type="text" id="id_email" name="email" value="{{ register_form.email.value|default:"" }}" placeholder="请输入您的邮箱地址" />
</div>
<div class="form-group marb8 {% if register_form.errors.password %}errorput{% endif %}">
<label>密 码</label>
<input type="password" id="id_password" name="password" placeholder="请输入6-20位非中文字符密码" />
</div>
<div class="form-group marb8 captcha1 {% if register_form.errors.captcha %}errorput{% endif %}">
<label>验 证 码</label>
{{ register_form.captcha }}
</div>
<div class="error btns" id="jsEmailTips">
{% for key,error in register_form.errors.items %}
{{ error }}
{% endfor %}
{{ msg }}
</div>
<div class="auto-box marb8">
</div>
<input class="btn btn-green" id="jsEmailRegBtn" type="submit" value="注册并登录" />
{% csrf_token %}
</form>
刷新验证码
刷新验证码的功能是前端完成的
//刷新验证码
function refresh_captcha(event){
$.get("/captcha/refresh/?"+Math.random(), function(result){
$('#'+event.data.form_id+' .captcha').attr("src",result.image_url);
$('#id_captcha_0').attr("value",result.key);
});
return false;
}
发送邮件
这里使用新浪邮箱,首先注册一个新浪邮箱,开启SMTP服务
TIM截图20180908142647.png
TIM截图20180908142751.png
在apps目录下新建一个utils包,在这个包里面新建一个email_send.py文件
#!/usr/bin/env python
# -*- coding: utf-8 -*-
# @Time : 2018/9/7 下午 08:24
# @Author : gao
# @File : email_send.py
from random import Random
from django.core.mail import send_mail
from MxOnline.settings import EMAIL_FROM
from users.models import EmailVerifyRecord
# 生成随机字符串
def random_str(random_length=8):
str = ''
# 生成字符串的可选字符串
chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
length = len(chars) - 1
random = Random()
for i in range(random_length):
str += chars[random.randint(0, length)]
return str
# 发送注册邮件
def send_register_eamil(email, send_type="register"):
# 发送之前先保存到数据库，到时候查询链接是否存在
# 实例化一个EmailVerifyRecord对象
email_record = EmailVerifyRecord()
# 生成随机的code放入链接
code = random_str(16)
email_record.code = code
email_record.email = email
email_record.send_type = send_type
email_record.save()
# 定义邮件内容:
email_title = ""
email_body = ""
if send_type == "register":
email_title = "慕课在线 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)
# 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，发件人邮箱地址，收件人（是一个字符串列表）
send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
# 如果发送成功
if send_status:
pass
if send_type == "forget":
email_title = "慕课在线 找回密码链接"
email_body = "请点击下面的链接找回你的密码: http://127.0.0.1:8000/reset/{0}".format(code)
# 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，从哪里发，接受者list
send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
# 如果发送成功
if send_status:
pass
邮箱激活
# 激活用户的view
class ActiveUserView(View):
def get(self, request, active_code):
# 查询邮箱验证记录是否存在
all_record = EmailVerifyRecord.objects.filter(code = active_code)
# 如果不为空也就是有用户
if all_record:
for record in all_record:
# 获取到对应的邮箱
email = record.email
# 查找到邮箱对应的user
user = UserProfile.objects.get(email=email)
user.is_active = True
user.save()
# 激活成功跳转到登录页面
return render(request, "login.html", )
# 自己瞎输的验证码
else:
return render(request, "active_fail.html")
在templates目录下创建 active_fail.html,代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<p style="color: red;">链接失效</p>
</body>
</html>
添加激活邮箱的路由
re_path('active/(?P<active_code>.*)/',ActiveUserView.as_view(),name='user_active'),
忘记密码
点击忘记密码,跳转到忘记密码界面,输入邮箱和验证码后给该邮箱发送重置密码链接
邮箱收到链接后,点击链接跳转到重置密码界面,输入新密码点击提交,成功后跳转到登陆界面
路由设置
path('forget/',ForgetPwdView.as_view(),name='forget_pwd'),
新建一个form
class ForgetPwdForm(forms.Form):
'''忘记密码'''
email = forms.EmailField(required=True)
captcha = CaptchaField(error_messages={'invalid': '验证码错误'})
逻辑代码
class ForgetPwdView(View):
'''找回密码'''
def get(self,request):
forget_form = ForgetPwdForm()
return render(request,'forgetpwd.html',{'forget_form':forget_form})
# post方法实现
def post(self, request):
forget_form = ForgetPwdForm(request.POST)
# form验证合法情况下取出email
if forget_form.is_valid():
email = request.POST.get("email", "")
# 发送找回密码邮件
send_register_eamil(email, "forget")
# 发送完毕返回登录页面并显示发送邮件成功。
return render(request, "login.html", {"msg": "重置密码邮件已发送,请注意查收"})
# 如果表单验证失败也就是他验证码输错等。
else:
return render(request, "forgetpwd.html", {"forget_from": forget_form})
修改forgetpwd.html表单提交内容
<form id="jsFindPwdForm" method="post" action="/forget/" autocomplete="off">
<div class="form-group marb20 ">
<label>帐 号</label>
<input type="text" id="account" name="email" placeholder="邮箱" />
</div>
<div class="form-group captcha1 marb38">
<label>验 证 码</label>
{{ forget_form.captcha }}
</div>
<div class="error btns" id="jsForgetTips">
{% for key,error in forget_from.errors.items %}
{{ error }}
{% endfor %}
{{ msg }}
</div>
<input type="hidden" name="sms_type" value="1">
<input class="btn btn-green" id="jsFindPwdBtn" type="submit" value="提交" />
<p class="form-p" style="bottom:40px;">您还可以<a href="/login/"> [直接登录]</a></p>
{% csrf_token %}
</form>
密码重置
配置路由
re_path('reset/(?P<active_code>.*)/', ResetView.as_view(), name='reset_pwd'),
逻辑代码
# 重置密码的view
class ResetView(View):
def get(self, request, active_code):
# 查询邮箱验证记录是否存在
all_record = EmailVerifyRecord.objects.filter(code=active_code)
# 如果不为空也就是有用户
if all_record:
for record in all_record:
# 获取到对应的邮箱
email = record.email
# 将email传回来
return render(request, "password_reset.html", {"email":email})
# 自己瞎输的验证码
else:
return render(
request, "forgetpwd.html", {
"msg": "您的重置密码链接无效,请重新请求"})
创建修改密码的form表单
# 重置密码form实现
class ModifyPwdForm(forms.Form):
# 密码不能小于5位
password1 = forms.CharField(required=True, min_length=5)
# 密码不能小于5位
password2 = forms.CharField(required=True, min_length=5)
配置路由
path('modify_pwd/', ModifyPwdView.as_view(), name='modify_pwd'),
逻辑代码
# 修改密码
class ModifyPwdView(View):
def post(self, request):
modiypwd_form = ModifyPwdForm(request.POST)
if modiypwd_form.is_valid():
pwd1 = request.POST.get("password1", "")
pwd2 = request.POST.get("password2", "")
email = request.POST.get("email", "")
# 如果两次密码不相等，返回错误信息
if pwd1 != pwd2:
return render(request, "password_reset.html", {"email": email, "msg": "密码不一致"})
# 如果密码一致
user = UserProfile.objects.get(email=email)
# 加密成密文
user.password = make_password(pwd2)
# save保存到数据库
user.save()
return render(request, "login.html", {"msg": "密码修改成功，请登录"})
# 验证失败说明密码位数不够。
else:
email = request.POST.get("email", "")
return render(request, "password_reset.html", {"email": email, "modiypwd_form":modiypwd_form})
需要两个类是因为get请求和post请求参数不同
html文件根据以前的方法进行配置即可
