Export whole wiki in cli (xar) via wget and basic auth

Help / Discuss

Hello Community,

im trying to automate a simple xar backup to transfer some pages to a offline backup xwiki instance.

Im using this to authenticate which works:
‘wget ‘https://user:password@hostname.com.donotresolve/xwiki/bin/view/Main/WebHome?basicauth=1’’

Doing the backup works with:
‘https://hostname.com.donotresolve/xwiki/bin/export/Space/Page?format=xar&pages=PAGE.%25’

I tried both togehter with:

wget ‘https://user:password@hostname.org/xwiki/bin/export/Space/Page?basicauth=1&format=xar&pages=PAGE.%25’ -O export.xar

which doesnt work.

Any idea how to combine basic auth with the export url?

Thank you

i figured it out:

Login to xwiki
curl -k -b cookies.txt -c cookies.txt -d
“j_username=xwiki_backup_user &j_password= xwiki_backup_user_password
&j_rememberme=true&submit=Log-in” “https:// xwiki_backup_server
:443/xwiki/bin/loginsubmit/XWiki/XWikiLogin”

download the xar:

curl -k --output "xwiki_backup_file "
-b cookies.txt -c cookies.txt "https:// xwiki_backup_server
/xwiki/bin/export/Space/Page?format=xar&pages=xwiki_backup_page "

if somebody needs that in ansible, heres a simple playbook which does the login and stores the xar export

  • name: Backup xWiki
    hosts: localhost
    gather_facts: true
    vars_files:

    • “vars/main.yml”
      tasks:

    • name: Login to Xwiki
      ansible.builtin.uri:
      url: “https://{{ xwiki_backup_server }}/xwiki/bin/loginsubmit/XWiki/XWikiLogin”
      method: POST
      url_password: “{{ xwiki_backup_user_password }}”
      url_username: “{{ xwiki_backup_user }}”
      status_code: 302
      validate_certs: false
      body_format: form-urlencoded
      force_basic_auth: true
      return_content: true
      register: login

    • name: Download and store export
      ansible.builtin.uri:
