我想捕獲產生路由錯誤的URL。我的最終目標是更改網址上的網域,以檢查它是否存在於我們的舊網站上(更改了網域),如果是,則重定向到舊網站。這是我所做的。Rails:捕獲產生ActionController :: RoutingError的URL
unless Rails.application.config.consider_all_requests_local
rescue_from Exception, with: :render_500
rescue_from ActionController::RoutingError, with: :check_old_site
rescue_from ActionController::UnknownController, with: :render_404
rescue_from ActionController::UnknownAction, with: :render_404
rescue_from ActiveRecord::RecordNotFound, with: :render_404
end
private
def check_old_site(exception)
#Need to edit the URL but I need access to before I can write the code to modify
captured_and_modified_url = ???
case Net::HTTP.get_response(URI.parse(captured_and_modified_url))
when Net::HTTPSuccess then redirect_to captured_and_modified_url
else render_404(exception)
end
end
def render_404(exception)
@not_found_path = exception.message
respond_to do |format|
format.html { render template: 'errors/error_404', layout: 'layouts/application', status: 404 }
format.all { render nothing: true, status: 404 }
end
end
因此,對於這個問題,我只想得到404錯誤的網址。感謝您的任何幫助。
