http_fs base_url: Accesses the HTTP file system rooted at
The following access methods are supported (compare with
path_encoding: Returns the passed
path_encoding. Paths are always encoded.
path_exclusions: is just
read: is supported. All files are considered as binary. The
`Skipflag works, and is translated to a
write: is supported and translated to
PUT. It is assumed that
PUTtruncates existing files, and creates new files. The
`Exclusiveflag is not supported and will be rejected.
size: this works only if the server includes the
Content-lengthheader in responses to
test_list: The tests
`Sshould work. Files are never symlinks.
`Ris handled like
`Xis handled like
`X(i.e. it is assumed that all files are readable, and all directories can be entered). The
`Wtest is never successful.
remove: is translated to a
readdir: works if index pages are generated (see above)
config_pipeline: one can enable further features on the pipeline object (e.g. authentication, proxies)
streaming: if true, the
readmethod only reads as much data from the HTTP connection as requested by the user. This assumes that the user does not pause stream accesses for longer periods as this would risk a server timeout. Also, there is no way for the client to automatically reconnect to the HTTP server after crashes. If false (the default), files are first downloaded to a temporary file before they are made accessible as
in_obj_channel. Streaming can also be enabled for each
`Streamingin the list of flags.
tmp_directory: directory for temporary files
tmp_prefix: file prefix for temporary files (w/o directory)
path_encoding: The encoding that is used for the file names. This must match the encoding the server assumes for translating file names to hyperlinks. Unfortunately, there is no way to query the server for this. The default,
`Enc_utf8, seems to be the de-facto standard on the web (e.g. browsers use UTF-8 when non-ASCII characters are entered in the address line).
is_error_response: This function is invoked with the current call object as soon as the response header arrives. It looks at the response code, and checks whether the response is successful or not. In the latter case the function returns the exception to raise. This function can be called several times during the execution of an operation. If it is called at a moment where only the response header is available but not the response body it is ensured that it will be called again with the full response later. Defaults to
