我讨厌调试这类错误。
大多数时候，我只是在 Rails 控制台中手动执行控制器中的代码。

这次我猜 404 可能是来自第 111 行

app/controllers/uploads_controller.rb

main


      
                end
            end
          
            render json: uploads.to_json
          end
          
          def show
            # do not serve uploads requested via XHR to prevent XSS
            return xhr_not_allowed if request.xhr?
          
            return render_404 if !RailsMultisite::ConnectionManagement.has_db?(params[:site])
          
            RailsMultisite::ConnectionManagement.with_connection(params[:site]) do |db|
              return render_404 if SiteSetting.prevent_anons_from_downloading_files && current_user.nil?
          
              if upload =
                   Upload.find_by(sha1: params[:sha]) ||
                     Upload.find_by(id: params[:id], url: request.env["PATH_INFO"])
                unless Discourse.store.internal?
                  local_store = FileStore::LocalStore.new
                  return render_404 unless local_store.has_been_uploaded?(upload.url)

Discourse.store.list_missing_uploads(skip_optimized: true) 会给你什么？
