aiohttp_tus

aiohttp_tus.setup_tus(app, *, upload_path, upload_url='/uploads', upload_resource_name=None, allow_overwrite_files=False, decorator=None, on_upload_done=None, json_dumps=<function dumps>, json_loads=<function loads>)[source]

Setup tus protocol server implementation for aiohttp.web application.

It is a cornerstone of aiohttp-tus library and in most cases only thing developers need to know for setting up tus.io server for aiohttp.web application.

Parameters

  • app (Application) – aiohttp.web.Application instance

  • upload_path (Path) –

    pathlib.Path instance to point the directory where to store uploaded files. Please, esnure that given directory is exists before application start and is writeable for current user.

    It is possible to prepend any match_info param from named URL.

  • upload_url (str) – tus.io upload URL. Can be plain as /uploads or named as /users/{username}/uploads. By default: "/uploads"

  • upload_resource_name (Optional[str]) – By default aiohttp-tus will provide auto name for the upload resource, as well as for the chunk resource. But sometimes it might be useful to provide exact name, which can lately be used for URL reversing.

  • allow_overwrite_files (bool) – When enabled allow to overwrite already uploaded files. This may harm consistency of stored data, cause please use this param with caution. By default: False

  • decorator (Optional[Callable[[Callable[[Request], Awaitable[StreamResponse]]], Callable[[Request], Awaitable[StreamResponse]]]]) – In case of guarding upload views it might be useful to decorate them with given decorator function. By default: None (which means ANY client will able to upload files)

  • on_upload_done (Optional[Callable[[Request, Resource, Path], Awaitable[None]]]) – Coroutine to call after upload is done. Coroutine will receive three arguments: request, resource & file_path. Request is current aiohttp.web.Request instance. Resource will contain all data about uploaded resource such as file name, file size (aiohttp_tus.data.Resource instance). While file path will contain pathlib.Path instance of uploaded file.

  • json_dumps (Callable[[Any], str]) –

    To store resource metadata between chunk uploads aiohttp-tus using JSON files, stored into upload_path / ".metadata" directory.

    To dump the data builtin Python function used: json.dumps(), but you might customize things if interested in using ujson, orjson, rapidjson or other implementation.

  • json_loads (Callable[[str], Any]) – Similarly to json_dumps, but for loading data from JSON metadata files. By default: json.loads()

Return type

Application

aiohttp_tus.data

class aiohttp_tus.data.Resource(file_name, file_size, offset, metadata_header, uid=NOTHING)[source]

Dataclass to store resource metadata.

Given dataclass used internally in between resource chunk uploads and is passed to on_upload_done callback if one is defined at aiohttp_tus.setup_tus() call.

Parameters

  • uid (str) – Resource UUID. By default: str(uuid.uuid4())

  • file_name (str) – Resource file name.

  • file_size (int) – Resource file size.

  • offset (int) – Current resource offset.

  • metadata_header (str) – Metadata header sent on initiating resource upload.
