1.创建项目 cmd django-admin startpoject cloudms
2.创建APP cmd django-admin startapp msgapp
3.修改settings,TEMPLATES中
TEMPLATES = [ { 'DIRS': [os.path.join(BASE_DIR,'msgapp/templates')], }
4.编写HTML文件
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>云端留言板(1)首页</title> </head> <body> <h1>提交留言功能区</h1> <form action="/msggate/" method="post"> {% csrf_token %} 发送方 <input type="text" name="userA" /> <br> 接收方 <input type="text" name="userB" /> <br> 消息文 <input type="text" name="msg" /> <br> <input type="submit" value="留言提交" /> </form> <h1>获取留言功能区</h1> <form action="/msggate/" method="get"> 接收方<input type="text" name="userC" /> <br> <input type="submit" value="留言获取"> </form> <table border="1"> <thead> <th>留言时间</th> <th>留言来源</th> <th>留言信息</th> <th>我的留言</th> </thead> <br> <tbody> {% for line in data %} <tr> <td>{{ line.time }}</td> <td align="center">{{ line.userA }}</td> <td>{{ line.msg }}</td> <td>{{ line.userB }}</td> </tr> {% endfor %} </tbody> </table> </body> </html>
5.编写views文件
from django.shortcuts import render # Create your views here. from django.shortcuts import render from datetime import datetime def msgproc(requset): datalist = [] if requset.method == 'POST': userA = requset.POST.get('userA',None) userB = requset.POST.get('userB',None) msg = requset.POST.get('msg',None) time = datetime.now() with open('msgdata.txt','a+') as f: f.write('{}--{}--{}--{}-- '.format(userB,userA, msg,time.strftime('%Y-%m-%d %H:%M:%S'))) if requset.method == 'GET': userC = requset.GET.get('userC',None) if userC != None: with open('msgdata.txt','r') as f: cnt = 0 for line in f: linedata =line.split('--') if linedata[0] == userC: cnt = cnt + 1 d = {'userA':linedata[1],'msg':linedata[2], 'time':linedata[3],'userB':linedata[0]} datalist.append(d) if cnt >= 10: break return render(requset,'MsgSingleWeb.html',{'data':datalist})
6.配置本地路由：新增urls
from django.urls import path from . import views urlpatterns = [ path('', views.msgproc), ]
7.配置全局路由：
from django.contrib import admin from django.urls import path,include urlpatterns = [ path('admin/', admin.site.urls), path('msggate/',include('msgapp.urls')) ]
8.启动项目：cmd python manage.py runserver 0:8080
