添加新的处理程序来运行 python Tornado 服务器 [英] Adding new handler to running python tornado server

问题描述

我是 Python Tornado 服务器的新手，我正在为我的下一个必须在实时环境中工作的项目评估 Python Tornado.我已经使用 Web Socket 实现从 github 运行了一个示例代码.

I'm new to python tornado server, and I were evaluating python tornado for my next project that has to work on real time environment. I've run a sample code from github with Web Socket implementation.

这是示例代码片段.

    app = web.Application([
       (r'/', IndexHandler),
       (r'/ws', SocketHandler),
       (r'/api', ApiHandler),
       (r'/(favicon.ico)', web.StaticFileHandler, {'path': '../'}),
       (r'/(rest_api_example.png)', web.StaticFileHandler, {'path': './'}),
   ])

   if __name__ == '__main__':
       app.listen(8080)
       ioloop.IOLoop.instance().start()

代码按预期正常工作.

是否可以提供类似云的解决方案，以便我可以向 Web 应用程序动态添加新路由和处理程序，而无需重新启动侦听端口的服务器.

Whether it is possible to give a cloud like solution so that I could add new routes and handlers dynamically to the web application without restarting the server listening a port.

例如；服务器开始运行并为路由/"提供 index.html，它有 n 个查看器.如果一个新的需求伴随着路由/foo"来提供 foo.html 而不会阻塞路由/"的 n 个查看者.如果有的话，有哪些不重启服务器的可能处理方式.

For example; The server starts running and serves index.html for the route '/' and it has n viewers. If a new requirement came with route '/foo' to be served foo.html without blocking the n viewers of route '/'. What are the possible ways to handle without restarting the server, if any.

推荐答案

你需要 tornado.web.Application 的 add_handlers 方法；像这样使用它:

You'll need the tornado.web.Application's add_handlers method; use it like this:

app.add_handlers(
    r".*",  # match any host
    [
        (
            r"/foo/([^/]*)",
            FooHandler
        ),
        (
            r"/bar/([^/]*)",
            BarHandler
        ),
    ]
)

从它的代码来看，它不会阻塞任何东西.

Judging by its code, it does not block anything.
