重置密码：
（1）重置密码激活邮箱的url
re_path('reset/(?P<active_code>.*)/', ResetView.as_view(), name='reset_pwd'),
（2）写重置密码（get方式）后台逻辑
class ResetView(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
return render(request, "password_reset.html", {"email":email})
else:
return render(request, "active_fail.html")
return render(request, "login.html")
（3）创建修改密码的form表单
class ModifyPwdForm(forms.Form):
'''重置密码'''
password1 = forms.CharField(required=True, min_length=5)
password2 = forms.CharField(required=True, min_length=5)
（4）修改密码的url
上面那个是激活邮箱的url，有active_code参数，只能写get方式的逻辑。
这里必须单独新建一个修改密码的url,因为如果以post方式提交的话，post提交的地方跟get方式（url中需要active_code参数）的地址不一样，action="{% url 'modify_pwd' %}
path('modify_pwd/', ModifyPwdView.as_view(), name='modify_pwd'),
（5）修改密码的后台逻辑
class ModifyPwdView(View):
def post(self, request):
modify_form = 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 = UserProfile.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 })
（6）修改password_reset.html
