Question

问题here和here没有帮助：（

我试图处理＆＃34; /favicon.ico"但它没有按预期工作。它有线......

我的处理程序如下：

handlers = [ 
    (r'^/$', RootHandler),    # this works fine
    (r'^/favicon\.ico$', IconHandler),
    # other handlers
]

我的IconHandler看起来像是：

class IconHandler(tornado.web.RequestHandler):
    def get(self):
        self.set_header("Content-Type", "image/vnd.microsoft.icon")
        with open(icon_path, 'rb') as f:
            self.write(f.read())
        return self.flush()

但是http://127.0.0.1:8000/favicon.ico给了我404错误：

Traceback (most recent call last):
  File "/home/tyler/.pyenv/versions/3.4.2/lib/python3.4/site-packages/tornado/web.py", line 1334, in _execute
    result = yield result
  File "/home/tyler/.pyenv/versions/3.4.2/lib/python3.4/site-packages/tornado/gen.py", line 628, in run
    value = future.result()
  File "/home/tyler/.pyenv/versions/3.4.2/lib/python3.4/site-packages/tornado/concurrent.py", line 109, in result
    raise_exc_info(self._exc_info)
  File "<string>", line 3, in raise_exc_info
  File "/home/tyler/.pyenv/versions/3.4.2/lib/python3.4/site-packages/tornado/gen.py", line 175, in wrapper
    yielded = next(result)

    self.root, absolute_path)
  File "/home/tyler/.pyenv/versions/3.4.2/lib/python3.4/site-packages/tornado/web.py", line 2286, in validate_absolute_path
    raise HTTPError(404)
tornado.web.HTTPError: HTTP 404: Not Found

所以我更改了网址匹配模式并进行了一些测试：

handler pattern        | url                                   | status
-----------------------|---------------------------------------|--------
r'^/favicon\.ico$'     | http://127.0.0.1:8000/favicon.ico     | 404Error
r'/favicon\.ico'       | http://127.0.0.1:8000/favicon.ico     | 404Error
r'/favicon.ico'        | http://127.0.0.1:8000/favicon.ico     | 404Error
r'^/sub/favicon\.ico$' | http://127.0.0.1:8000/sub/favicon.ico | Works!
r'/sub/favicon\.ico'   | http://127.0.0.1:8000/sub/favicon.ico | Works!
r'/sub/favicon.ico'    | http://127.0.0.1:8000/sub/favicon.ico | Works!

请帮助。我无法理解:(

python：3.4.2

龙卷风：4.0.2

Ubuntu：14.10

我相信您的应用设置中有static_path字段。你的情况会发生什么：

您可以通过将static_path设置作为a发送来提供静态文件关键字参数。

和

请注意，StaticFileHandler可以自动安装 static_path设置

配置static_path设置后，

会自动将Favicon模式插入到处理程序模式列表中。这些自动静态模式的优先级高于您自己的所有模式。

这是你的追溯证明：

  File "/home/tyler/.pyenv/versions/3.4.2/lib/python3.4/site-packages/tornado/web.py", line 2286, in validate_absolute_path
    raise HTTPError(404)

因此，我建议您从应用设置中删除static_path，然后添加您自己的/static模式

(r"/static/(.*)", web.StaticFileHandler, {"path": my_path}),

python-tornado不匹配“/favicon.ico”
