用户名和密码验证:
首先在settings.py 把csrf注释如图:

修改login.html 代码如下:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" href="/static/commons.css" />
<style>
label{
width: 80px;
text-align: right;
display: inline-block;
}
</style>
</head>
<body>
<form action="/login" method="post">
<p>
<label for="username">用户名：</label>
<input id="username" name="user" type="text" />
</p>
<p>
<label for="password">密码：</label>
<input id="password" name="pwd" type="password" />
<input type="submit" value="提交" />
<span style="color: red;">{{ error_msg }}</span>
</p>
</form>
<script src="/static/jquery.min.js"></script>
</body>
</html>
注意form不要写错
- 修改
- 修改views.py 代码如下:
from django.shortcuts import render
# Create your views here.
from django.shortcuts import HttpResponse
from django.shortcuts import render
def login(request):
# 包含用户提交的所有信息
# 获取用户提交方法
print(request.method)
return render(request, 'login.html')
# def login(request):
# # f = open('templates/login.html', 'r', encoding='utf-8')
# # date = f.read()
# # f.close()
# # return HttpResponse(date)
# return render(request,'login.html')
def home(request):
return HttpResponse('<h1>CMDB</h1>')
- 运行django访问( http://127.0.0.1:8000/login )
- 效果图如下(GET方式访问服务器):
- 能得到用户是用GET方式访问服务器
-
- 效果图如下(POST方式访问服务器)点击提交:
-
获取用户表单输入的数据:
from django.shortcuts import render
# Create your views here.
from django.shortcuts import HttpResponse
from django.shortcuts import render
def login(request):
# 包含用户提交的所有信息
# 获取用户提交方法
# print(request.method)
# 判断用户名和密码
if request.method == "POST":
# 获取用户通过POST提交过来的数据
user = request.POST['user']
pwd = request.POST['pwd']
print(user,pwd)
return render(request, 'login.html')
# def login(request):
# # f = open('templates/login.html', 'r', encoding='utf-8')
# # date = f.read()
# # f.close()
# # return HttpResponse(date)
# return render(request,'login.html')
def home(request):
return HttpResponse('<h1>CMDB</h1>')
- 运行(效果图)
上述再修改views.py 进行改进:
- views.py :
from django.shortcuts import render
# Create your views here.
from django.shortcuts import HttpResponse
from django.shortcuts import render
# 重定向
from django.shortcuts import redirect
def login(request):
# 包含用户提交的所有信息
# 获取用户提交方法
# print(request.method)
# 判断用户名和密码
if request.method == "POST":
# 获取用户通过POST提交过来的数据(用户不存在返回None)
user = request.POST.get('user',None)
pwd = request.POST.get('pwd',None)
if user == 'root' and pwd == "123":
# 去跳转到(重定向)
return redirect('http://www.baidu.com')
# user = request.POST['user']
# pwd = request.POST['pwd']
# print(user,pwd)
return render(request, 'login.html')
# def login(request):
# # f = open('templates/login.html', 'r', encoding='utf-8')
# # date = f.read()
# # f.close()
# # return HttpResponse(date)
# return render(request,'login.html')
def home(request):
return HttpResponse('<h1>CMDB</h1>')
输入(u: root, m: 123)
- 效果图:
- 扩充
- views.py 添加以下({'error_msg': '123'}):
- 注意这里:
效果图(不输入密码):
上述再修改:
from django.shortcuts import render
# Create your views here.
from django.shortcuts import HttpResponse
from django.shortcuts import render
# 重定向
from django.shortcuts import redirect
def login(request):
# 包含用户提交的所有信息
# 获取用户提交方法
# print(request.method)
# 判断用户名和密码
error_msg = ""
if request.method == "POST":
# 获取用户通过POST提交过来的数据(用户不存在返回None)
user = request.POST.get('user',None)
pwd = request.POST.get('pwd',None)
if user == 'root' and pwd == "123":
# 去跳转到(重定向)
return redirect('http://www.baidu.com')
else:
# 用户密码不正确
error_msg = "用户名或密码错误"
# user = request.POST['user']
# pwd = request.POST['pwd']
# print(user,pwd)
return render(request, 'login.html', {'error_msg': error_msg})
# def login(request):
# # f = open('templates/login.html', 'r', encoding='utf-8')
# # date = f.read()
# # f.close()
# # return HttpResponse(date)
# return render(request,'login.html')
def home(request):
return HttpResponse('<h1>CMDB</h1>')
