如何使用多个静态文件夹处理 Tornado 中的静态文件处理程序？

Question

我目前的路由表如下：

routing_table = [
        ("/api/ping", PingHandler),
        ("/css/(.*)", StaticFileHandler, {
             "path": "my-website-path/css"
        }),
        ("/js/(.*)", StaticFileHandler, {
             "path": "my-website-path/js"
        }),
        ("/fonts/(.*)", StaticFileHandler, {
             "path": "my-website-path/fonts"
        })

我只想使用一个正则表达式来处理我的静态文件。像下面这样的东西？

routing_table = [
        ("/api/ping", PingHandler),
        ("/(css|js|fonts)/(.*)", StaticFileHandler, {
             "path": "my-website-path/"
        })

我该怎么做？提前谢谢你。

Answer 1

A RequestHandler 将所有匹配项作为位置参数传递给 http-verb 函数。由于 StaticFileHandler 扩展了它并且您有 2 个捕获的组，因此您的代码将无法按预期工作。因此需要逐步更改正则表达式：

匹配整个路径：/(.*)
第一部分应该是字体，js或者css：((jss|css|fonts)/.*
内部组不应该被捕获-利用?:：((?:jss|css|fonts)/.*

密码

routing_table = [
        ("/api/ping", PingHandler),
        ("/((?:css|js|fonts)/.*)", StaticFileHandler, {
             "path": "my-website-path"
        }

请记住，StaitcFileHandler（如@cricket_007 所述）...

This handler is intended primarily for use in development and light-duty file serving; for heavy traffic it will be more efficient to use a dedicated static file server (such as nginx or Apache). We support the HTTP Accept-Ranges mechanism to return partial content (because some browsers require this functionality to be present to seek in HTML5 audio or video).
