问题 I would like to know if it is possible to use passport-http to secure the REST API of Hyperledger Composer generated with the composer-rest-server and what would be the export COMPOSER_PROVIDERS='{}' configuration.

If it were possible, how would the userID and userSecret be passed, as a special http header, in the body or as a simple basic

问题 EDIT: rest-server gives the option "Specify if you want the generated REST API to be secured: (y/N)", is this to enforce the acl?

问题 I have an AWS instance running Fabric created from an AWS Fabric template. Unfortunately, this is a Linux (not Ubuntu) instance. Now I'm trying to install the composer tools on the same instance. The docs say that I shouldn't install anything as a root, but the system won't let me install Node unless I'm a root. When I'm trying to install composer-cli (w/o sudo), I get various permission errors. Is itpossible at all to install composer on a non-Ubuntu system? Another option is to connect to

REST client's log is as below. I'm using a default generated Angular app. Any suggestions? 回答1: I figured out the issue in my code. It
