import tornado.ioloop

import tornado.web
INPUT_LIST=[]
class MainHandle(tornado.web.RequestHandler):
    def get(self):
        #self.write("Hello,world")
        self.render('s1.html',xxxooo=INPUT_LIST)
    def post(self, *args, **kwargs):
        name=self.get_argument('xxx')
        INPUT_LIST.append(name)
        self.render('s1.html',xxxooo=INPUT_LIST)
settings={
    "template_path" : "template",
    "static_path" : "static",
}
#路由映射，路由系统
application=tornado.web.Application([
    (r"/index",MainHandle),
],**settings)

if __name__=="__main__":
    application.listen(8000)
    tornado.ioloop.IOLoop.instance().start()

3.tornado框架

写：

-继承类

-application

-run

-配置文件

-模板路径

补充

self.get_argument("xxx") #获取用户提交数据

POST只能通过input提交

GET可以通过url传送给后台

模板预演：

{% for item in xxxooo %}

{% end %}

模板语言：

{{}}

{}

-uimethod

def func(self,arg):
    return arg.lower()

-uimodule

from tornado.web import UIModule
from tornado import escape

class custom(UIModule):
    def render(self, *args, **kwargs):
        return "1234"

import tornado.ioloop
import uimethod as mt
import uimodule as md
import tornado.web
INPUT_LIST=[]
class MainHandle(tornado.web.RequestHandler):
    def get(self):
        #self.write("Hello,world")
        self.render('s1.html',nap="NMP888",xxxooo=INPUT_LIST)
    def post(self, *args, **kwargs):
        name=self.get_argument('xxx')
        INPUT_LIST.append(name)
        self.render('s1.html',xxxooo=INPUT_LIST)
settings={
    "template_path" : "template",
    "static_path" : "static",
    "ui_methods":mt,
    "ui_modules":md,
}
#路由映射，路由系统
application=tornado.web.Application([
    (r"/index",MainHandle),
],**settings)

if __name__=="__main__":
    application.listen(8000)
    tornado.ioloop.IOLoop.instance().start()
