Django 使用者認證如果自己不想寫就可以用django內建的認證

首選匯入模組 models.py

#!/usr/bin/env python#_*_ coding:utf8 _*_from __future__ import unicode_literalsfrom django.db import modelsfrom django.core.exceptions import ValidationErrorfrom django.contrib.auth.models import User

每建立一個使用者都在

class UserProfile(models.Model):    user = models.OneToOneField(User)    name = models.CharField(max_length=64)    school = models.ForeignKey(‘School‘)    def __unicode__(self):        return self.name

OneToOneField欄位是一對一不能重複關聯的關係

使用者認證

首選實現一個簡單的訪問

大項目urls.py

from django.conf.urls import url,includefrom django.contrib import adminfrom app01 import viewsurlpatterns = [    url(r‘^admin/‘, admin.site.urls),    url(r‘^$‘, views.index),]

views.py views.py在app01下面

#!/usr/bin/env python
#_*_ coding:utf8 _*_
from django.shortcuts import render,redirect
import models
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger


def index(request):    return render(request,‘crm/index.html‘)

在crm下面建立index.html 代碼如下：

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title></head><body>Welcome to Oldboy CRM</body></html>

訪問http://127.0.0.1:8000

認證之後才能看到頁面資訊如何?呢這個在實際工作當中經常遇到的如何?呢一步一步實現

views.py

#!/usr/bin/env python#_*_ coding:utf8 _*_from django.shortcuts import render,redirectimport modelsfrom django.core.paginator import Paginator, EmptyPage, PageNotAnIntegerfrom app01 import formsfrom django.contrib.auth.decorators import login_required@login_requireddef index(request):    return render(request,‘crm/index.html‘)

匯入模組 login_required 在函數下面加上裝飾器進行驗證

再次訪問試試

跳轉到http://127.0.0.1:8000/accounts/login/?next=/ 這個連結地址

好我們來寫個簡單的登入頁面

urls代碼如下

from django.conf.urls import url,includefrom django.contrib import adminfrom app01 import viewsurlpatterns = [    url(r‘^admin/‘, admin.site.urls),    url(r‘^$‘, views.index),    url(r‘^accounts/login/$‘, views.acc_login),]

views.py代碼如下：

#!/usr/bin/env python
#_*_ coding:utf8 _*_
from django.shortcuts import render,redirect,HttpResponseRedirect
import models
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
from app01 import forms
from django.contrib.auth.decorators import login_required
from  django.contrib.auth import authenticate,login,logout


@login_requireddef index(request):    return render(request,‘crm/index.html‘)def acc_login(request):    if request.method == ‘POST‘:        print(request.POST)        user = authenticate(username=request.POST.get(‘username‘),                            password=request.POST.get(‘password‘))        if user is not None:            login(request,user)            return HttpResponseRedirect(‘/‘)        else:            login_err = "Wrong username or password!"            return render(request,‘crm/login.html‘,{‘login_err‘:login_err})    return render(request,"crm/login.html")

建立模板html index.html

index.html代碼如下

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title></head><body><h1>Oldboy Welcome</h1>{% block page-container %}Welcome to Oldboy CRM<div>{% if request.user.is_authenticated %}<span>{{ request.user.userprofile.name }}</span>{% else %} <span>登入/註冊</span> {% endif %}</div>{% endblock %}</body></html>

{% extends ‘crm/index.html‘ %}{% block page-container %}    <form action="" method="post"> {% csrf_token %}   Username: <input type="text" name="username">   Password: <input type="password" name="password">            <input type="submit" value="Log me in">    {% if login_err %}    <div style="color: red">{{ login_err }}</div>    #前端判斷錯誤 如果錯誤顯示views裡面的內容    {% endif %}    </form>{% endblock %}]

好我們實現了訪問使用者限制

http://127.0.0.1:8000 自動跳轉到

我們輸入正確的使用者名稱密碼會跳轉到index.html頁面

user = authenticate(username=request.POST.get(‘username‘),                            password=request.POST.get(‘password‘))        if user is not None:            login(request,user)            return HttpResponseRedirect(‘/‘)

顯示使用者名稱登入成功名字如何顯示和退出系統

顯示登入成功的名字需要在最上層顯示

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title></head><body><h1>Oldboy Welcome</h1>{% block page-container %}Welcome to Oldboy CRM<div>{% if request.user.is_authenticated %}<span>{{ request.user.userprofile.name }}</span>{% else %} <span>登入/註冊</span> {% endif %}</div><div><a href="/accounts/logout/">退出系統</a></div>{% endblock %}</body></html>

看紅色顯示部分

退出系統代碼看黃色部分前端

url代碼如下

from django.conf.urls import url,includefrom django.contrib import adminfrom app01 import viewsurlpatterns = [    url(r‘^admin/‘, admin.site.urls),    url(r‘^$‘, views.index),    url(r‘^accounts/login/$‘, views.acc_login),    url(r‘^accounts/logout/$‘, views.acc_logout),]

views.py代碼如下：

def acc_logout(request):    logout(request)    return HttpResponseRedirect(‘/‘)

點擊退出系統跳轉到

<a href="/accounts/logout/">退出系統</a>

def acc_logout(request):    logout(request)    return HttpResponseRedirect(‘/‘) 跳轉到登入頁面
