问题 I just simply use the tornado application together with threading as the following code: def MakeApp(): return tornado.web.Application([(r"/websocket", EchoWebSocket), ]) def run_tornado_websocket(): app = MakeApp() http_server = tornado.httpserver.HTTPServer(app, ssl_options={ "certfile": os.path.join(os.path.abspath("."), "server.crt"), "keyfile": os.path.join(os.path.abspath("."), "server_no_passwd.key"), }) http_server.listen(options.port) tornado.ioloop.IOLoop.current().start() if __name

问题 I am trying to make a game server with python, using tornado. The problem is that WebSockets don't seem to work with wsgi. wsgi_app = tornado.wsgi.WSGIAdapter(app) server = wsgiref.simple_server.make_server('', 5000, wsgi_app) server.serve_forever() After looking trough this answer on stackoverflow, Running Tornado in apache, I've updated my code to use a HTTPServer , which works with websockets. server = tornado.httpserver.HTTPServer(app) server.listen(5000) tornado.ioloop.IOLoop.instance()

用pip安装tornado库: python -m pip install tornado 出现问题一: Could not fetch URL https://pypi.org/simple/twisted/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/twisted/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping 解决办法:python -m pip install tornado --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org 即在库名后+ --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org 出现问题二:pip.

1. 什么情况下使用Python语言开发比较好?/你对Python怎么看?/。。。    回答思路:   时间线:   1991年,第一个稳定的Python版本;   2000年,Python2.7稳定版本发布;   2008年,Python3发布;   2020年,Python2不再维护;   空间线:   Python设计哲学;   Python2、3特性;   和其他编程语言(如c++)对比;   语言选型考虑因素;   思路串联:设计哲学(Python本质特性)-> 如何选型(正面回答,取其精华) -> 埋下一个问题引子   示例答案:Python自1991年Rossum编写发布出第一个版本以来,便一直遵循着其设计哲学”简单、明确、优雅“,设计哲学的根本出发点就决定了Python这门语言的编程开发的易用性和工作高效性,同样的业务需求实现,可能传统编程语言C++程序猿需要1周工期,而Python程序猿很有可能三天不到就能完成,而且潜在隐藏的问题会少很多,因为Python本身目前有非常庞大的开源第三方库,同时封装了很多复杂的语言底层操作如内存分配与释放,指针的相关操作等;   在具体的项目实践过程中,开发语言的选型需要考虑到几个方面:项目业务本身的特点适合哪种语言、公司历史的技术栈和人员技术储备倾向于哪种语言、选型的语言当前领域内的生态体系和发展前景(比如是否不在维护)

python web框架之Tornado的简单使用

☆樱花仙子☆ 提交于 2020-12-19 06:44:00
python web框架有很多,比如常用的有django,flask等。今天主要介绍Tornado ,Tornado是一个用Python写的相对简单的、不设障碍的Web服务器架构,用以处理上万的同时的连接口,让实时的Web服务通畅起来。虽然跟现在的一些用Python写的Web架构相似,比如Django,但Tornado更注重速度,能够处理海量的同时发生的流量。接下来,就开始撸起来吧。 1.首先需要安装Tornado库: pip install tornado 2.新建一个python文件(demo.py)代码如下: import tornado.web # 这里定义一个类并继承RequestHandler这类作为路由类 class MainHandler(tornado.web.RequestHandler): # 重写get方法 def get(self): # 输出内容到界面 self.write('Hello, world') # 这里就是路由配置 app = tornado.web.Application([ ('/', MainHandler), ] ) if __name__ =='__main__': # 设置监听端口 app.listen(9999) # 启动服务器 tornado.ioloop.IOLoop.instance().start() 3.运行demo

问题 I'm new to Tornado and web services in general. In my application, I've Qt/c++ client and python Tornado on server side. The Qt client sends commands in the form of text messages(e.g. "ws://192.121.1.213:8080? function =myfunction? args =params..").Now, I want to use secure web socket i.e. wss in stead of ws . What changes are required on server and client side? Pointer to any online example would be also helpful. Thanks. 回答1: Pass the ssl_options argument when constructing your HTTPServer :

cookie 在上节课,我们简单了解了登录过程,但是很明显,每次都需要登录,但是在平常逛网站的只需要登录一次,那么网站是如何记录登录信息的呢? 有没有什么办法可以让浏览器记住登录信息,下次再次打开的时候,可以自动登录呢? 设置cookie与获取cookie import sys import time import tornado.web import tornado.ioloop import tornado.httpserver import tornado.options from tornado.web import RequestHandler from tornado.options import define,options import util.ui_modules import util.ui_methods # import time from data.connect import session from data.user_modules import UserDetails, User define( ' port ' ,default=8080,help= ' run server ' ,type= int) class MainHandler(RequestHandler): def get(self): self.write( ' cookie
