1：一个简单的web框架
# 导包
from wsgiref.simple_server import make_server
#自定义个处理函数
def application(environ,start_response):
start_response("200 OK",[(‘Content-Type‘,‘text/html‘)])
return [b‘<h1>Hello,web!</h1>‘]
httpd = make_server(‘‘,8091,application)
print(‘Serving HTTP on port 8091....‘)
httpd.serve_forever()
HelloWorld
# 导包
from wsgiref.simple_server import make_server
#自定义个处理函数
def application(environ,start_response):
# 获取路径
path = environ["PATH_INFO"]
start_response("200 OK",[(‘Content-Type‘,‘text/html‘)])
if path=="/yang":
return [b‘<h1>Hello,yang!</h1>‘]
elif path=="/Aaron":
return [b‘<h1>Hello,aaron!</h1>‘]
else:
return [b‘<h1>404!</h1>‘]
httpd = make_server(‘‘,8091,application)
print(‘Serving HTTP on port 8091....‘)
httpd.serve_forever()
2.0
# 导包
from wsgiref.simple_server import make_server
def yang():
f=open("yang.html","rb")
data=f.read()
return data
def aaron():
f=open("aaron.html","rb")
data=f.read()
return data
#自定义个处理函数
def application(environ,start_response):
# 获取路径
path = environ["PATH_INFO"]
start_response("200 OK",[(‘Content-Type‘,‘text/html‘)])
if path=="/yang":
return [yang()]
elif path=="/Aaron":
return [aaron()]
else:
return [b‘<h1>404!</h1>‘]
httpd = make_server(‘‘,8091,application)
print(‘Serving HTTP on port 8091....‘)
httpd.serve_forever()
调用HTML内容
# 导包
import time
from wsgiref.simple_server import make_server
def region(req):
pass;
def login(req):
print(req["QUERY_STRING"])
f=open("login.html",‘rb‘)
data=f.read();
return data;
def yang(req):
f=open("yang.html","rb")
data=f.read()
return data
def aaron(req):
f=open("aaron.html","rb")
data=f.read()
return data
def show_time(req):
times=time.ctime()
# 方法一：通过模板使用
# con=("<h1>time:%s</h1>" %str(times)).encode("utf8")
# return con
# 方法二：字符串替换
f = open("show_time.html", "rb")
data = f.read()
data=data.decode("utf8")
data =data.replace("{{time}}",str(times))
return data.encode("utf8")
# 定义路由
def router():
url_patterns=[
("/login",login),
("/region", region),
("/yang", yang),
("/aaron", aaron),
("/show_time",show_time),
]
return url_patterns
#自定义个处理函数
def application(environ,start_response):
# 获取路径
path = environ["PATH_INFO"]
start_response("200 OK",[(‘Content-Type‘,‘text/html‘)])
url_patterns = router()
func =None
for item in url_patterns:
if item[0]==path:
func=item[1]
break
if func:
return [func(environ)]
else:
return [b‘404‘]
httpd = make_server(‘‘,8091,application)
print(‘Serving HTTP on port 8091....‘)
httpd.serve_forever()
模拟路由
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
margin: 0;
padding: 0;
}
</style>
</head>
<body>
<h1>时间：{{time}}}</h1>
</body>
</html>
show_time.html
2：一个简单的django案例
Django的下载与安装
如何检验是否安装成功？
2.1 创建django项目的两种方法
--创建Django项目 django-admin startproject mysite --创建应用 python manage.py startapp blog
通过命令创建
方式2：通过Pycharm创建
创建成功
大致分为三步
a：修改urls.py 类似控制器，把想要展示的内容通过地址配置一下
b:在views中设置具体的逻辑
c：在templates中设置要显示的页面内容
通过命令行启动django。
python manage.py runserver 8091
如何引用js
a：添加static文件，并把js放置到该文件下
b：在setting文件中配置
c：在对应的文件中做引用
URL配置(URLconf)：又叫做路由系统，其本质是提供路径和视图函数之间的调用映射表。
格式：
urlpatterns=[
url(正在表达式，views视图函数，参数，别名)
]
例1：匹配 XXX/articles/年份（只能匹配4位数字）
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from blog import views
urlpatterns = [
path(‘admin/‘, admin.site.urls),
path(‘show_time/‘,views.show_time),
url(r‘^articles/[0-9]{4}/$‘, views.year_archive),
]
urls.py--1.0
from django.shortcuts import render,HttpResponse
import time
def show_time(request):
# return HttpResponse("Hello")
return render(request,"index.html",{"time":time.ctime()})
# Create your views here.
def year_archive(request):
return HttpResponse("2018");
Views.py
例2：如何获取到地址栏中的年份（通过路由添加()匹配）
例3：给分组命名
urls中的配置
url(r‘^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})$‘, views.year_archive),
views视图中的代码
return HttpResponse(year+"-"+month)
例四：注册小练习
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="" method="post">
<p>姓名 <input type="text" name="name"></p>
<p>年龄 <input type="text" name="age"></p>
<p>爱好 <input type="checkbox" name="hobby" value="1">读书
<input type="checkbox" name="hobby" value="2">写字
<input type="checkbox" name="hobby" value="3">看报
</p>
<p><input type="submit"></p>
</form>
</body>
</html>
Register.html
from django.shortcuts import render,HttpResponse
import time
def show_time(request):
# return HttpResponse("Hello")
return render(request,"index.html",{"time":time.ctime()})
# Create your views here.
def year_archive(request,month,year):
return HttpResponse(year+"-"+month)
def Register(request):
if request.method=="POST":
con="Hello,%s，你的年龄是%s"%(request.POST.get("name"),request.POST.get("age"))
return HttpResponse(con)
return render(request,"Register.html")
Views.py
"""django01 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 django.conf.urls import url
from blog import views
urlpatterns = [
path(‘admin/‘, admin.site.urls),
path(‘show_time/‘,views.show_time),
url(r‘^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})$‘, views.year_archive),
url(r‘^Register/‘, views.Register),
]
urls.py
注意：需要把这句代码给注释掉
效果图
在url中给地址设置一个别名，这样后期Register名称的修改将不影响系统中其他调用的功能
URL分发
效果：
