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()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="">
<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('{}--{}--{}--{}--\n'.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 =
for line in f:
linedata =line.split('--')
if linedata[] == userC:
cnt = cnt +
d = {'userA':linedata[],'msg':linedata[],\
'time':linedata[],'userB':linedata[]}
datalist.append(d)
if cnt >= :
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
