Virtual File System¶

Cozy applications can use files for storing binary content, like photos or bills in PDF. This service offers a REST API to manipulate easily without having to know the underlying storage layer. The metadata are kept in CouchDB, but the binaries can go to the local system, or a Swift instance.

Directories¶

A directory is a container for files and sub-directories.

Its path is the path of its parent, a slash (/), and its name. It’s case sensitive.

Root directory¶

The root of the virtual file system is a special directory with id io.cozy.files.root-dir.

You can use it in any request where you would use a directory, except you cannot delete it.

POST /files/:dir-id¶

Create a new directory. The dir-id parameter is optional. When it’s not given, the directory is created at the root of the virtual file system.

Query-String¶

Parameter	Description
Type	`directory`
Name	the directory name
Tags	an array of tags
CreatedAt	the creation date

HTTP headers¶

Parameter	Description
Date	The modification date of the directory

Request¶

POST /files/fce1a6c0-dfc5-11e5-8d1a-1f854d4aaf81?Type=directory&Name=phone&Tags=bills,konnectors HTTP/1.1
Accept: application/vnd.api+json
Date: Mon, 19 Sep 2016 12:35:08 GMT

Status codes¶

404 Not Found, when the parent directory does not exist
409 Conflict, when a directory with the same name already exists
422 Unprocessable Entity, when the Type or Name parameter is missing or invalid

GET `/files/_changes`¶

This endpoint is similar to the changes feed of CouchDB for io.cozy.files. There are a few specificities:

it is wrapped in the VFS lock to avoid seeing inconsistent results
it automatically skips design docs
if the requests is coming from an OAuth client, it excludes the files and directories that are in a not synchronized folder
it only supports the options since, limit, and include_docs of CouchDB
it has an option fields to only include those fields in the results
it has an option include_file_path to add the path for files
it has two options skip_deleted and skip_trashed to not send to the client the deleted/trashed files and directories.

POST `/files/_find`¶

Find allows to find documents using a mango selector. You can read more about mango selectors here.

Note that it returns a bookmark in the links, useful to paginate (following the JSON-API pagination). On the last page, there won’t be a links.next.

It is possible to pass a execution_stats parameter to get some information about the query execution. See here for more details.

PATCH /files/:file-id and PATCH /files/metadata¶

Both endpoints can be used to update the metadata of a file or directory, or to rename/move it. The difference is the first one uses an id to identify the file/directory to update, and the second one uses the path.

Some specific attributes of the patch can be used:

dir_id attribute can be updated to move a file or directory
move_to_trash boolean to specify that the file needs to be moved to the trash
permanent_delete boolean to specify that the files needs to be deleted (after being trashed)

HTTP headers¶

It’s possible to send the If-Match header, with the previous revision of the file/directory (optional).

      "meta": {"rev": "2-123123"},
      "attributes": {"move_to_trash": true}
    }
  ]
}

Status codes¶

The same status codes can be encountered as the PATCH /files/:file-id route.

POST /files/archive¶

Create an archive. The body of the request lists the files and directories that will be included in the archive. For directories, it includes all the files and sub-directories in the archive.

It’s possible to give a file by its id (in the ids array) or by its path (in the files array).

The generated archive is temporary and is not persisted.

Request¶

POST /files/archive HTTP/1.1
Content-Type: application/vnd.api+json

{
  "data": {
    "type": "io.cozy.files.archives",
    "attributes": {
      "name": "project-X",
      "ids": ["a51aeeea-4f79-11e7-9dc4-83f67e9494ab"],
      "files": [
        "/Documents/bills",
        "/Documents/images/sunset.jpg",
        "/Documents/images/eiffel-tower.jpg"
      ]
    }
  }
}

Response¶

HTTP/1.1 200 OK
Content-Type: application/vnd.api+json

{
  "links": {
    "related": "/files/archive/4521DC87/project-X.zip"
  },
  "data": {
    "type": "io.cozy.files.archives",
    "id": "4521DC87",
    "attributes": {
      "href": "/files/archive/4521DC87/project-X.zip"
    }
  }
}

GET /files/archive/:key/:name¶

Download a previously created archive. The name parameter is not used in the stack but aims to allow setting a name even for browser / downloader that do not support Content-Disposition filename.

This route does not require Basic Authentification

GET /files/archive/4521DC87/project-X.zip HTTP/1.1
Accept: application/zip
Content-Length: 12345
Content-Disposition: attachment; filename="project-X.zip"
Content-Type: application/zip

POST /files/downloads?Path=file_path¶

Create a file download. The Path query parameter specifies the file to download. The response json API links contains a related link for downloading the file, see below.

POST /files/downloads?Id=file_id¶

Also create a file download. But it takes the id of the file and not its path.

POST /files/downloads?VersionId=file_id/version_id¶

This is a third way to create a file download. But, this time, it is for downloading an old version of a file.

These 3 routes also accept a Filename=... parameter in the query-string to change the filename that will be used for the downloaded file.

GET /files/downloads/:secret/:name¶

Allows to download a file with a secret created from the route above.

The name parameter is not used in the stack but aims to allow setting a name even for browser / downloader that do not support Content-Disposition filename.

By default the content-disposition will be inline, but it will be attachment if the query string contains the parameter Dl=1

This route does not require Basic Authentification

Versions¶

The identifier of the io.cozy.files.versions is composed of the file-id and another string called the version-id, separated by a /. So, when a route makes reference to /something/:file-id/:version-id, you can use the identifier of the version document (without having to prepend the file identifier).

GET /files/download/:file-id/:version-id¶

Download an old version of the file content

By default the content-disposition will be inline, but it will be attachment if the query string contains the parameter Dl=1

Request¶

GET /files/download/9152d568-7e7c-11e6-a377-37cbfb190b4b/1-0e6d5b72 HTTP/1.1

POST /files/:file-id/versions¶

Create a new version of a file, with the same content but new metadata. It requires a permission for PUT on the file, as it is equivalent to upload the same content of the file.

Query-String¶

Parameter	Description
Tags	an array of tags

Request¶

POST /files/9152d568-7e7c-11e6-a377-37cbfb190b4b/metadata HTTP/1.1

      }
    }
  ]
}

POST /files/trash/:file-id¶

Restore the file with the file-id identifiant into its restore_path. If a file already exists at the restore path with the same name, a suffix will be added to avoid any conflict.

The file’s trashed attributes will be set to false.

DELETE /files/trash/:file-id¶

Destroy the file and make it unrecoverable (it will still be available in backups).

DELETE /files/trash¶

Clear out the trash.

Trashed attribute¶

All files that are inside the trash will have a trashed: true attribute. This attribute can be used in mango queries to only get “interesting” files.

Real-time via websockets¶

In addition to the normal events for files, the stack also injects some events when a thumbnail is generated. A permission on io.cozy.files is required to subscribe to those events on io.cozy.files.thumbnails.

Example¶

client > {"method": "AUTH",
          "payload": "xxAppOrAuthTokenxx="}
client > {"method": "SUBSCRIBE",
          "payload": {"type": "io.cozy.files.thumbnails"}}
