今天完成的功能是：用户忘记密码后，通过注册邮箱重置密码…
首先还是把前端页面准备好，把forgetpwd.html复制到templates目录下
编辑users.views.py，创建一个忘记密码的类
class ForgetPwdView(View):
def get(self, request):
return render(request, 'forgetpwd.html', {})
配置一条url
...
from users.views import ForgetPwdViewurlpatterns = [
...
url(r'^forget/$', ForgetPwdView.as_view(), name='forget_pwd'),
]
在login.html中，编辑”忘记密码”的url, 顺便把注册也改一下
把forgetpwd.html中的静态文件路径都改下（css/images/js）
然后我们访问这个页面如下：127.0.0.1:8000/forget/
忘记密码需要输入注册时的邮箱，还要填写验证码。因此我们也需要对这两个表单进行form验证，编辑users.forms.py
class ForgetForm(forms.Form):
email = forms.EmailField(required=True)
captcha = CaptchaField(error_messages={'invalid': '验证码错误'})
在后台逻辑加上form验证
...
from .forms import LoginForm, RegisterForm, ForgetFormclass ForgetPwdView(View):
def get(self, request):
forget_form = ForgetForm()
return render(request, 'forgetpwd.html', {'forget_form': forget_form})
编辑forgetpwd.html
现在刷新忘记密码页面，验证码已经显示出来了
用户填写邮箱后需要发送邮件，编辑utrls.email_send.py
from random import Random
from django.core.mail import send_mail
from users.models import EmailVerifyRecord
from mxonline.settings import EMAIL_FROMdef 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 strdef 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 elif send_type == 'forget':
email_title = '慕学在线网密码重置'
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
在templates目录下创建一个邮件发送成功后跳转的页面send_success.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>邮件发送成功</title>
</head>
<body><p>邮件已经发送成功，请注意查收！</p></body>
</html>
完善后台逻辑
class ForgetPwdView(View):
def get(self, request):
forget_form = ForgetForm()
return render(request, 'forgetpwd.html', {'forget_form': forget_form}) def post(self, request):
forget_form = ForgetForm(request.POST)
if forget_form.is_valid():
email = request.POST.get('email', '')
user = UserProfile.objects.filter(email=email)
if user:
sendEmail(email, 'forget')
return render(request, 'send_success.html')
else:
return render(request, 'forgetpwd.html', {'forget_form': forget_form, 'msg': '用户不存在'})
else:
return render(request, 'forgetpwd.html', {'forget_form':forget_form})
再修改下前面页面，添加错误信息显示
启动服务，测试找回密码，收到邮件
[重置密码]
最后，还需要写一个重置密码的接口：用户点击重置密码连接后的动作
把重置密码页面password_reset.html拷贝到templates目录下
编辑users.views.py，写一个处理重置密码的类
class ResetPwdView(View):
def get(self, request, reset_code):
all_records = EmailVerifyRecord.objects.filter(code=reset_code)
if all_records:
for record in all_records:
email = record.email #获取是哪个用户的链接
return render(request, 'password_reset.html', {'email': email})
else:
return render(request, 'reset_fail.html')
return render(request, 'login.html')
在templates创建一个重置密码失败的页面reset_fail.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>重置密码失败</title>
</head>
<body><p>该链接无效！</p></body>
</html>
编辑urls.py配置一条重置密码的url
from users.views import ResetPwdView
...urlpatterns = [
url(r'^reset/(?P<reset_code>.*)/$', ResetPwdView.as_view(), name='reset_pwd'),
]
编辑password_reset.html,添加一个隐藏的input ,这个input的值就是email
现在访问发送到邮箱的重置密码连接，会跳转到重置密码页面
查看网页源码，可以发现之前我们添加的隐藏的input，这样到时提交把这个值传到后台就知道修改哪个账户的密码了
接下来做用户提交后的逻辑
编辑users.form.py来写一个form对重置密码的表单进行验证
class ResetPwdForm(forms.Form):
pwd = forms.CharField(required=True, min_length=6)
repwd = forms.CharField(required=True, min_length=6)
编辑users.view.py写提交的逻辑
class ModifyPwdView(View):
def post(self, request):
resetpwd_form = ResetPwdForm(request.POST)
if resetpwd_form.is_valid():
pwd = request.POST.get('pwd', '')
repwd = request.POST.get('repwd', '')
email = request.POST.get('email', '')
if pwd == repwd:
user = UserProfile.objects.get(email=email)
user.password = make_password(repwd)
user.save()
return render(request, 'login.html')
else:
return render(request, 'password_reset.html', {'msg':'密码不一致'})
else:
return render(request, 'password_reset.html', {'resetpwd_form':resetpwd_form})
添加一个提交的url
...
from users.views import ModifyPwdViewurlpatterns = [
url(r'modifypwd/$', ModifyPwdView.as_view(), name='modify_pwd'),
]
编辑password_reset.html
现在可以重置密码了，修改完成后会跳转到登录页面
