有没有更好的方法用 Tornado 处理 index.html? [英] is there a better way to handle index.html with Tornado?

问题描述

我想知道是否有更好的方法来使用 Tornado 处理我的 index.html 文件.

我使用 StaticFileHandler 处理所有请求，并使用特定的 MainHandler 处理我的主要请求.如果我只使用 StaticFileHandler 我得到一个 403: Forbidden 错误

GET http://localhost:9000/警告:root:403 GET/(127.0.0.1): 不是文件

这里是我现在的做法:

import os导入 tornado.ioloop导入 tornado.web从龙卷风进口网__author__ = 'gvincent'root = os.path.dirname(__file__)端口 = 9999类 MainHandler(tornado.web.RequestHandler):定义获取(自我):尝试:使用 open(os.path.join(root, 'index.html')) 作为 f:self.write(f.read())除了 IOError 作为 e:self.write("404: 未找到")application = tornado.web.Application([(r"/", MainHandler),(r"/(.*)", web.StaticFileHandler, dict(path=root)),])如果 __name__ == '__main__':application.listen(端口)tornado.ioloop.IOLoop.instance().start()

解决方案

事实证明 Tornado 的 StaticFileHandler 已经包含默认文件名功能.

在 Tornado 版本 1.2.0 中添加了功能:https://github.com/tornadoweb/tornado/commit/638a151d96d681d3bdd42a5cf4bd681d35cf4b5c5c5bdc7b

要指定默认文件名，您需要将default_filename"参数设置为 WebStaticFileHandler 初始化的一部分.

更新您的示例:

导入操作系统导入 tornado.ioloop导入 tornado.webroot = os.path.dirname(__file__)端口 = 9999application = tornado.web.Application([(r"/(.*)", tornado.web.StaticFileHandler, {"path": root, "default_filename": "index.html"})])如果 __name__ == '__main__':application.listen(端口)tornado.ioloop.IOLoop.instance().start()

这将处理根请求:

• / -> /index.html

子目录请求:

• /tests/ -> /tests/index.html

并且似乎可以正确处理目录的重定向，这很好:

• /tests -> /tests/index.html

I want to know if there is a better way to handle my index.html file with Tornado.

I use StaticFileHandler for all the request,and use a specific MainHandler to handle my main request. If I only use StaticFileHandler I got a 403: Forbidden error

GET http://localhost:9000/
WARNING:root:403 GET / (127.0.0.1):  is not a file

here how I doing now:

import os
import tornado.ioloop
import tornado.web
from  tornado import web

__author__ = 'gvincent'

root = os.path.dirname(__file__)
port = 9999

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        try:
            with open(os.path.join(root, 'index.html')) as f:
                self.write(f.read())
        except IOError as e:
            self.write("404: Not Found")

application = tornado.web.Application([
    (r"/", MainHandler),
    (r"/(.*)", web.StaticFileHandler, dict(path=root)),
    ])

if __name__ == '__main__':
    application.listen(port)
    tornado.ioloop.IOLoop.instance().start()

解决方案

Turns out that Tornado's StaticFileHandler already includes default filename functionality.

Feature was added in Tornado release 1.2.0: https://github.com/tornadoweb/tornado/commit/638a151d96d681d3bdd6ba5ce5dcf2bd1447959c

To specify a default file name you need to set the "default_filename" parameter as part of the WebStaticFileHandler initialization.

Updating your example:

import os
import tornado.ioloop
import tornado.web

root = os.path.dirname(__file__)
port = 9999

application = tornado.web.Application([
    (r"/(.*)", tornado.web.StaticFileHandler, {"path": root, "default_filename": "index.html"})
])

if __name__ == '__main__':
    application.listen(port)
    tornado.ioloop.IOLoop.instance().start()

This handles root requests:

• / -> /index.html

sub-directory requests:

• /tests/ -> /tests/index.html

and appears to correctly handle redirects for directories, which is nice:

• /tests -> /tests/index.html
