Authentication

All the api requests except for login require an Authorization header. The header pattern is: Authorization: Bearer <token>. The token can be obtained from the login api.

A token expires in 24 hours. A new token is needed once the old one expires. Tokens can be re-used in multiple requests before exiration.

Security

This program encrypts all the traffic end-to-end using https. It requires you to set up a digital certificate. There are many ways that you can get a free digital certificate. You may also generate your own self-signed digital certificate:

cd ~/shadowsocks-restful-api/
openssl req -nodes -x509 -newkey rsa:4096 -keyout server.key -out server.cert -days 365

Reliability

This program aims to achieve best reliability. It will attempt to re-open the ports upon restart of shadowsocks or this program itself. It also keeps monitoring the opened ports. Should anyone were dropped (due to any unprecedented reason), this program would attemp to re-open it.
