前言
跟账号相关的功能一般是注册，登录，修改密码，密码找回功能，前面实现了登录和注册功能，本篇讲下修改密码功能实现
修改密码html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>注册页面</title>
</head>
<body>
<h1>新用户注册！</h1>
<form action="" method="post">
{% csrf_token %}
<p>
用户名：<input type="text" id="id_username" name="username", required="required">*
</p>
<p>
密码：<input type="password" id="id_psw" name="password", required="required">*
</p>
<p>
新密码：<input type="password" id="id_new" name="new", required="required">*
</p>
<p>{{ msg }}</p>
<p>
<input type="submit" value="确定">
</p>
</form>
</body>
</html>views和urls
from django.shortcuts import render
from django.contrib.auth.hashers import make_password, check_password
# Create your views here.
def reset_psw(request):
'''修改密码'''
res = ""
if request.method == "GET":
return render(request, 'reset_psw.html', {'msg': res})
if request.method == "POST":
username = request.POST.get('username')
psw = request.POST.get('password')
new_psw = request.POST.get('new')
if psw == new_psw:
res = "新密码和旧密码不能重复"
return render(request, 'reset_psw.html', {'msg': res})
else:
# 先查询数据库是否有此用户名
user_lst = User.objects.filter(user_name=username)
if not user_lst:
# 如果没这个用户
res = "用户未注册：%s" % username
return render(request, 'reset_psw.html', {'msg': res})
else:
# 如果注册过，判断密码对不对
ret = User.objects.filter(user_name=username).first()
# 校验密码
is_psw_true = check_password(psw, ret.psw)
if is_psw_true:
user = User()
user.psw = make_password(new_psw)
user.save()
res = "密码修改成功！"
else:
res = "密码错误！"
return render(request, 'reset_psw.html', {'msg': res})
urls.py访问地址
from django.conf.urls import url
from hello import views
urlpatterns = [
# 新增用户
url(r'^register/', views.register),
url(r'^login/', views.login),
url(r'^reset/', views.reset_psw),
]实现效果如下
