Download file content

GET /data/{id}/content

Returns the content of a file or directory specified by $FILE_ID.

If $FILE_ID is a regular file, returns its binary content. Partial content download is also supported using Range header.

If $FILE_ID is a directory, returns a TAR archive with its contents. Any nested files or subdirectories to which the client does not have access (e.g. due to insufficient POSIX permissions or ACLs) are omitted in the resulting archive. Request for directory download results in a redirection URL (in Location header) that contains the ID of a temporary download session. The URL can be used to download the tarball, with support for resuming interrupted downloads using the Range header (where the range start is the number of already downloaded bytes and the range end is omitted).

Example cURL requests

Download entire file content

curl -H "X-Auth-Token: $TOKEN" \
-X GET "https://$PROVIDER_HOST/api/v3/oneprovider/data/$FILE_ID/content"

abcdefghijklmno

Download only part of the file content

curl -H "X-Auth-Token: $TOKEN" \
-X GET "https://$PROVIDER_HOST/api/v3/oneprovider/data/$FILE_ID/content" \
-H "Range: bytes=5-8"

fghi

Download a directory as tar archive

curl -sD - -H "X-Auth-Token: $TOKEN" \
-X GET "https://$PROVIDER_HOST/api/v3/oneprovider/data/$DIR_ID/content" | grep location

location: https://$PROVIDER_HOST/download/$DOWNLOAD_ID

curl https://$PROVIDER_HOST/download/$DOWNLOAD_ID > directory.tar

Download a directory as tar archive in a single request

curl -L -H "X-Auth-Token: $TOKEN" \
-X GET "https://$PROVIDER_HOST/api/v3/oneprovider/data/$DIR_ID/content"

Resume download of a directory (previous download failed after 12345678 bytes)

curl -H "Range: bytes=12345678-" https://$PROVIDER_HOST/download/$DOWNLOAD_ID >> directory.tar

Download a directory as tar archive in a single request without resolving symlinks

curl -L -H "X-Auth-Token: $TOKEN" \
-X GET "https://$PROVIDER_HOST/api/v3/oneprovider/data/$DIR_ID/content?follow_symlinks=false"
