1.创建Django工程。
参考https://www.cnblogs.com/CK85/p/10159159.html中步骤。
2.在urls.py文件中添加url分发路径
"""Django_test URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/2.1/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path(‘‘, views.home, name=‘home‘) Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path(‘‘, Home.as_view(), name=‘home‘) Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path(‘blog/‘, include(‘blog.urls‘)) """ from django.contrib import admin from django.urls import path from app01 import views urlpatterns = [ path(‘admin/‘, admin.site.urls), path(‘login/‘, views.login, name=‘login‘), path(‘authentication/‘, views.authentication, name=‘authentication‘), ]
路径分发时编辑name可以为路径取一个别名,在html文件中通过别名进行访问,避免过多的命名的改变。
3.在view.py中添加两个界面的试图函数。
from django.shortcuts import render, HttpResponse import time # Create your views here. def login(request): return render(request, ‘login.html‘, locals()) def authentication(request): # print(request.method) user_name = request.GET.get(‘user‘) pwd = request.GET.get(‘pwd‘) user_dic = { ‘ck‘: ‘123‘, ‘ck1‘: ‘123‘, ‘ck2‘: ‘123‘, } if user_name in user_dic: if user_dic[user_name] == pwd: print(‘authentication passed‘) user = user_name output = render(request, ‘well_come.html‘, {‘username‘: user}) else: print(‘incorrect username or password‘) output = HttpResponse(‘<h1>incorrect username or password</h1>‘) else: print(‘不在‘) output = HttpResponse(‘<h1>the user dose not exist</h1>‘) return output
login视图函数在用户访问时将login.html发送给用户。
authentication进行用户登入信息的验证和处理。
HttpResponse返回一个http响应。
4.在templates文件夹中创建对应的html文件:
login.html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>登入</h1> <div> <form action="{% url "authentication" %}" > <p>手机号:<input type="text" name="user"></p> <p>密码:<input type="text" name="pwd"></p> <p><input type="submit" value="提交"></p> {% csrf_token %} </form> </div> </body> </html>
login界面是用户在登入时看到的界面,需要用户在该页面中输入账号和密码。
其中使用form表单进行读取数据,action=“/authentication/”与action=“{% url "authentiction" %}”相同,前者使用路径访问,后者使用别名访问。
在form表单中input标签type=’text‘ 和type=’submit‘组合使用,使得在用户点击提交按钮时使用form表单method中传入的方法将两个text中的值与text的name组成键值对传给在form表单action路径的文件。
well_come.html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>你好! {{ username }}</h1> </body> </html>
well_come界面为用户成功登入之后的欢迎界面。
