自定义python框架_Python自定义web框架、Jinja2
WSGI(Web Server Gateway Interface)是一种规范，它定义了使用python编写的web app与web server之间接口格式，实现web app与web server间的解耦。
python标准库提供的独立WSGI服务器称为wsgiref。
标准Web框架
#!/usr/bin/env python
#coding:utf-8
from wsgiref.simple_server import make_server
def RunServer(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/html')])
return '
Hello, web!
'if __name__ == '__main__':
httpd = make_server('', 8000, RunServer)
print "Serving HTTP on port 8000..."
httpd.serve_forever()
自定义Web框架
from wsgiref.simple_server import make_server
def login():
return 'login'
def index():
data = open('index.html','r').read()
return data
url = (
('/login/',login),
('/index/',index),
)
def RunServer(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/html')])
geturl = environ['PATH_INFO']
for item in url:
if item[0] == geturl:
return item[1]()
else:
return '404'
if __name__ == '__main__':

httpd.serve_forever()
MVC和MTV 代码堆放的归类
MVC：Model、View、Controller model存放数据操作，view存放html文件，controller负责逻辑处理
MTV：Model、Template、View
model存放数据操作，Template存放html文件，View负责逻辑处理
Django是 MTV模式
模板渲染jinja2
from wsgiref.simple_server import make_server
import time
from jinja2 import Template
import sys
reload(sys)
sys.setdefaultencoding('utf8') #//解决UnicodeDecodeError
def login():
return 'login'
def index():
data = open('index.html','r').read()
current_time = time.strftime('%Y-%m-%d %H:%M:%S')
template = Template(data) #使用jinja2模板处理
result = template.render(name='yangmv',
age='18',
current_time=current_time,
user_list=['wj','sb',],
num=1,
)
return result.encode('utf-8')
url = (
('/login/',login),
('/index/',index),
)
def RunServer(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/html')])
geturl = environ['PATH_INFO']
for item in url:
if item[0] == geturl:
return item[1]()
else:
return '404'
if __name__ == '__main__':
httpd = make_server('', 8000, RunServer)
print "Serving HTTP on port 8000..."
httpd.serve_forever()
{{ name }}
{{ age }}
{{ current_time }}
{% for item in user_list %}
{{item}}{% endfor %}
{% if num == 1 %}

{% else %}

{% endif %}
