在Tornado中禁用静态文件缓存

时间：2022-02-02 03:54:45

By default, Tornado puts a Cache-Control: public header on any file served by a StaticFileHandler. How can this be changed to Cache-Control: no-cache?

默认情况下,Tornado在StaticFileHandler提供的任何文件上放置一个Cache-Control:public头。如何将其更改为Cache-Control:no-cache?

Looking into the tornado/web.py it seems that the easiest way is to subclass the StaticFileHandler and override the set_extra_headers method.

查看tornado / web.py似乎最简单的方法是子类化StaticFileHandler并覆盖set_extra_headers方法。

def set_extra_headers(self, path):
    self.set_header("Cache-control", "no-cache")

The accepted answer does not work for Chrome. Subclass StaticFileHandler using the following:

接受的答案不适用于Chrome。子类StaticFileHandler使用以下内容:

class MyStaticFileHandler(tornado.web.StaticFileHandler):
    def set_extra_headers(self, path):
        # Disable cache
        self.set_header('Cache-Control', 'no-store, no-cache, must-revalidate, max-age=0')
