PyFilesystem can open a filesystem via an FS URL, which is similar to a URL you might enter in to a browser. FS URLs are useful if you want to specify a filesystem dynamically, such as in a conf file or from the command line.
FS URLs are formatted in the following way:
<protocol>://<username>:<password>@<resource>
The components are as follows:
<protocol>
Identifies the type of filesystem to create. e.g.osfs
,ftp
.<username>
Optional username.<password>
Optional password.<resource>
A resource, which may be a domain, path, or both.
Here are a few examples:
osfs://~/projects
osfs://c://system32
ftp://ftp.example.org/pub
mem://
ftp://will:daffodil@ftp.example.org/private
If <type>
is not specified then it is assumed to be an ~fs.osfs.OSFS
, i.e. the following FS URLs are equivalent:
osfs://~/projects
~/projects
Note
The username and passwords fields may not contain a colon (:
) or an @
symbol. If you need these symbols they may be percent encoded.
FS URLs may also be appended with a ?
symbol followed by a url-encoded query string. For example:
myprotocol://example.org?key1=value1&key2
The query string would be decoded as {"key1": "value1", "key2": ""}
.
Query strings are used to provide additional filesystem-specific information used when opening. See the filesystem documentation for information on what query string parameters are supported.
To open a filesysem with a FS URL, you can use ~fs.opener.registry.Registry.open_fs
, which may be imported and used as follows:
from fs import open_fs
projects_fs = open_fs('osfs://~/projects')
