How to use a Seafile generated upload-link w/o authentication token from command line

Question

With Seafile one is able to create a public upload link (eg https://cloud.seafile.com/u/d/98233edf89/ ) to upload files via Browser w/o authentication.

Seafile webapi does not support any upload w/o authentication token.

How can I use such kind of link from command line with curl or from python script?

Answer 1

needed 2 hours to find a solution with curl, it needs two steps:

1. make a get-request to the public uplink url with the repo-id as query parameter as follows:

curl 'https://cloud.seafile.com/ajax/u/d/98233edf89/upload/?r=f3e30b25-aad7-4e92-b6fd-4665760dd6f5' -H 'Accept: application/json' -H 'X-Requested-With: XMLHttpRequest'

The answer is (json) a id-link to use in next upload-post eg:

{"url": "https://cloud.seafile.com/seafhttp/upload-aj/c2b6d367-22e4-4819-a5fb-6a8f9d783680"}

2. Use this link to initiate the upload post:

curl 'https://cloud.seafile.com/seafhttp/upload-aj/c2b6d367-22e4-4819-a5fb-6a8f9d783680' -F file=@./tmp/index.html -F filename=index.html -F parent_dir="/my-repo-dir/"

The answer is json again, eg

[{"name": "index.html", "id": "0a0742facf24226a2901d258a1c95e369210bcf3", "size": 10521}]

done ;)

#!/usr/bin/env bash

# print vars key and value when DEBUG eq on
[[ "on" == "$DEBUG" ]] && echo -e "USER:${USER} PASSWORD:${PASSWORD} HOST:${HOST} FILE:${FILE} PARENT_DIR:${PARENT_DIR} REPO:${REPO} DEBUG:${DEBUG}"

# login and get token
TOKEN=$(curl -s --location --request POST "${HOST}/api2/auth-token/" --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode "username=${USER}" --data-urlencode "password=${PASSWORD}" | jq -r ".token")

[ -z "$TOKEN" ] && echo -e "${RED}login seafile faild${NC}, call your administrator plz!\n" && exit 1

# gen upload link 
UPLOAD_LINK=$(curl -s --header "Authorization: Token ${TOKEN}" "${HOST}/api2/repos/${REPO}/upload-link/?p=${PARENT_DIR}" | jq -r ".")

# upload file

# print upload result
[[ "on" == "$DEBUG" ]] && echo -e "TOKEN:${TOKEN} UPLOAD_LINK:${UPLOAD_LINK} UPLOAD_RESULT:${UPLOAD_RESULT}"

save as seafile-upload.sh

# ubuntu 
apt install -y jq
# centos 
# yum install -y jq
chmod +x ./seafile-upload.sh

./seafile-upload.sh -u <username> -p <password> -h <seafile server host> -f <upload file path> -d <parent dir default value is /,must be start with /> -r <repo id> -t <print debug info switch off/on,default off>
