From 7467361d706e38aa53b6bd2fcb919153327175ed Mon Sep 17 00:00:00 2001 From: ThibG Date: Sat, 12 May 2018 16:48:32 +0200 Subject: Fetch boosted statuses on behalf of a follower (fixes #7426) (#7459) When an ActivityPub Announce is processed and the boosted toot is not known, fetch it on behalf of one of the booster's followers. This is to allow fetching self-boosts of previously-unknown private toots. If fetching on behalf of a user fails, try fetching it anonymously: the selected follower of a boosting user may be banned by the boosted toot's author. --- app/helpers/jsonld_helper.rb | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) (limited to 'app/helpers/jsonld_helper.rb') diff --git a/app/helpers/jsonld_helper.rb b/app/helpers/jsonld_helper.rb index e9056166c..9d2b6cf00 100644 --- a/app/helpers/jsonld_helper.rb +++ b/app/helpers/jsonld_helper.rb @@ -52,18 +52,22 @@ module JsonLdHelper graph.dump(:normalize) end - def fetch_resource(uri, id) + def fetch_resource(uri, id, on_behalf_of = nil) unless id - json = fetch_resource_without_id_validation(uri) + json = fetch_resource_without_id_validation(uri, on_behalf_of) return unless json uri = json['id'] end - json = fetch_resource_without_id_validation(uri) + json = fetch_resource_without_id_validation(uri, on_behalf_of) json.present? && json['id'] == uri ? json : nil end - def fetch_resource_without_id_validation(uri) + def fetch_resource_without_id_validation(uri, on_behalf_of = nil) + build_request(uri, on_behalf_of).perform do |response| + return body_to_json(response.body_with_limit) if response.code == 200 + end + # If request failed, retry without doing it on behalf of a user build_request(uri).perform do |response| response.code == 200 ? body_to_json(response.body_with_limit) : nil end @@ -85,8 +89,9 @@ module JsonLdHelper private - def build_request(uri) + def build_request(uri, on_behalf_of = nil) request = Request.new(:get, uri) + request.on_behalf_of(on_behalf_of) if on_behalf_of request.add_headers('Accept' => 'application/activity+json, application/ld+json') request end -- cgit
