From 2872d706533fdbec26516e67a3c0259f3781ef29 Mon Sep 17 00:00:00 2001 From: Dillard Blom Date: Sat, 26 Sep 2026 12:23:28 +0200 Subject: [PATCH] Fix NC34 compatibility: vendor jQuery, send CSRF token explicitly on ajax calls Live-tested against nc01 after its auto-update jumped to NC 34.0.4: - Nextcloud's global jQuery has been deprecated since NC19 and is no longer reliably present/first-loaded on NC34 (other apps like serverinfo hit the same issue). occweb's index.js and the vendored jquery.terminal (term.js) both assume a global jQuery, so ship our own copy (js/jquery.js, 3.7.1 from code.jquery.com) and load it before them in templates/index.php. Fixes a hard "jQuery is not defined" crash that left the terminal blank (black screen). - With that fixed, every ajax call started failing with HTTP 412 "CSRF check failed": core only auto-attaches the requesttoken header to requests made through ITS OWN globally-loaded jQuery, and with occweb now vendoring a separate jQuery instance that no longer happens. A global $.ajaxSetup() call turned out unreliable (another app's later jQuery load can replace window.jQuery afterwards), so each of the three ajax calls (SQL query, initial completion list, occ command execution) now sets the requesttoken header explicitly via OC.requestToken. Bump max-version to 34 - actually verified working on NC 34.0.4 now, not inherited/guessed (see the policy comment in this same file). Version bump to 0.3.5. --- appinfo/info.xml | 4 ++-- js/index.js | 11 ++++++++++- js/jquery.js | 2 ++ templates/index.php | 5 +++++ 4 files changed, 19 insertions(+), 3 deletions(-) create mode 100644 js/jquery.js diff --git a/appinfo/info.xml b/appinfo/info.xml index 672f496..dc7132d 100644 --- a/appinfo/info.xml +++ b/appinfo/info.xml @@ -5,7 +5,7 @@ Extended OCC Web OCC Commands in a web terminal - 0.3.4 + 0.3.5 agpl Dillard Blom OCCWeb @@ -20,7 +20,7 @@ or guessed ahead.
