/ static /在此代码中是什么意思？

Question

Im trying to serve static html file in GO. This is how my code in main() looks like.

http.Handle("/", http.FileServer(http.Dir("/static/")))
http.ListenAndServe(":8989", nil)

It works but i dont understand what does static mean! Someone please explain.

This means that whenever you handle requests that serves HTTP requests with the contents of the file system rooted at root, it try to server files declared in http.Dir which uses the operating system's file system implementation.

This means that whenever you access your web server index url it will try to serve files under the operating system /static/ directory.

To serve a directory on disk under an alternate URL path you can use StripPrefix to modify the request URL's path before the FileServer sees it.

http.Handle("/static/", http.StripPrefix("/static/", http.FileServer(http.Dir("/your/directory/to/static/files"))))
http.ListenAndServe(":8989", nil)
