func FileServer ¶

func FileServer(root FileSystem) http.Handler

FileServer returns a handler that serves HTTP http.Requests with the contents of the file system rooted at root.

To use the operating system's file system implementation, use http.Dir:

http.Handle("/", http.FileServer(http.Dir("/tmp")))

As a special case, the returned file server redirects any http.Request ending in "/index.html" to the same path, without the final "index.html".

func ServeContent ¶

func ServeContent(w http.ResponseWriter, req *http.Request, name string, modtime time.Time, content io.ReadSeeker)

ServeContent replies to the http.Request using the content in the provided ReadSeeker. The main benefit of ServeContent over io.Copy is that it handles Range http.Requests properly, sets the MIME type, and handles If-Match, If-Unmodified-Since, If-None-Match, If-Modified-Since, and If-Range http.Requests.

If the response's Content-Type header is not set, ServeContent first tries to deduce the type from name's file extension and, if that fails, falls back to reading the first block of the content and passing it to DetectContentType. The name is otherwise unused; in particular it can be empty and is never sent in the response.

If modtime is not the zero time or Unix epoch, ServeContent includes it in a Last-Modified header in the response. If the http.Request includes an If-Modified-Since header, ServeContent uses modtime to decide whether the content needs to be sent at all.

The content's Seek method must work: ServeContent uses a seek to the end of the content to determine its size.

If the caller has set w's ETag header formatted per RFC 7232, section 2.3, ServeContent uses it to handle http.Requests using If-Match, If-None-Match, or If-Range.

Note that *os.File implements the io.ReadSeeker interface.

func ServeFile ¶

func ServeFile(w http.ResponseWriter, r *http.Request, name string)

ServeFile replies to the http.Request with the contents of the named file or directory.

If the provided file or directory name is a relative path, it is interpreted relative to the current directory and may ascend to parent directories. If the provided name is constructed from user input, it should be sanitized before calling ServeFile.

As a precaution, ServeFile will reject http.Requests where r.URL.Path contains a ".." path element; this protects against callers who might unsafely use filepath.Join on r.URL.Path without sanitizing it and then use that filepath.Join result as the name argument.

As another special case, ServeFile redirects any http.Request where r.URL.Path ends in "/index.html" to the same path, without the final "index.html". To avoid such redirects either modify the path or use ServeContent.

Outside of those two special cases, ServeFile does not use r.URL.Path for selecting the file or directory to serve; only the file or directory provided in the name argument is used.
