tornado之参数和模板

上一部分介绍了tornado的最基本的部分

现在送上tornado的参数和模板的使用

废话不多说直接上demo

#！/usr/bin/env python  #python2要加上这句，否则会乱码
import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web

from tornado.options import define,options

define('port',default=8000,help='run port',type=int)
# define('version',default='0.0.1',help='version 0.0.1',type=str)



class TestIndexHandler(tornado.web.RequestHandler):
    def get(self):
        name = self.get_argument('name','no')
        self.write('hello '+name + '\n')
        # abc = self.get_arguments('abc')
        # self.write(','.j· oin(abc))
        print(name)

class UserHandler(tornado.web.RequestHandler):
    def get(self,name,age):
        self.write('---name=%s---age=%s'%(name,age))

class BookNameHandler(tornado.web.RequestHandler):
    def get(self,name,age):
        '''通过url传入参数名是固定的'''
        print (self.request.remote_ip)
        self.write('---name=%s---age=%s'%(name,age))

class HtmlHandler(tornado.web.RequestHandler):
    def get(self, *args, **kwargs):
        self.render('index.html')

    def post(self, *args, **kwargs):
        name = self.get_argument('name','no')
        passwd = self.get_argument('password','no')
        st = '---name=%s---password=%s'%(name,passwd)
        self.write(st)

class MyHandler(tornado.web.RequestHandler):
    def get(self):
        self.write(self.request.remote_ip)
        print(self.request.remote_ip)
        print(self.request.connection)
        print(self.request.full_url())
        print(self.request.request_time())

if __name__ == '__main__':
    tornado.options.parse_command_line()
    # print(options.port)
    # print(options.version)
    app = tornado.web.Application(
        handlers=[
            (r'/test',TestIndexHandler),
            (r'/user/(.+)/([1-9]+)',UserHandler),
            (r'/bookname/(?P<name>.+)/(?P<age>[1-9]+)', BookNameHandler), #http://192.168.***.***:8000/bookname/jingqi/19
            (r'/html',HtmlHandler),
            (r'/request', MyHandler),
        ],
        template_path = 'templates',
        debug=True,
    )
    http_server = tornado.httpserver.HTTPServer(app)
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()

　首先在根文件夹下创建一个templates的文件夹，所有的HTML文件放置其中

导入代码中所示你会看到

template_path='templates'　#此处告诉脚本你的HTML问价你的路径
debug=True,    #此处是打开调试模式，这样设置之后就不必每次重启服务
