ChatECNU

ChatECNU is the ChatArch ECNU campus portal and campus-network automation package extracted from ChatNet.

It owns ECNU application-layer behavior: login/session handling, home/user/log reads, visitor account operations, ECNU ChatEnv schema, optional CAPTCHA automation, and a fail-closed wrapper around the external ECNU campus-network auth_client binary. Generic browser/session/table helpers are imported from ChatNet.

Quick start

pip install -e ".[dev]"
chatecnu --help
python -m pytest -q

Optional CAPTCHA automation:

pip install -e ".[captcha]"
chatecnu login --username "$ECNU_USERNAME" -i

Campus-network auth_client wrapper:

# Check current auth_client login state; this does not require a password.
chatecnu network-auth check \
  --auth-client /usr/local/bin/auth_client \
  --json

# Put ECNU_USERNAME/ECNU_PASSWORD in process env or ChatEnv, or use -i to prompt.
# Default login is fail-closed: it will not pass a password to auth_client argv.
chatecnu network-auth ensure-login \
  --auth-client /usr/local/bin/auth_client \
  -I

# Legacy opt-in only after accepting same-host process-list exposure:
chatecnu network-auth ensure-login \
  --auth-client /usr/local/bin/auth_client \
  --allow-argv-password \
  -I

ChatECNU does not vendor or redistribute the Linux-only auth_client binary. Pass its runtime path explicitly or set ECNU_AUTH_CLIENT in ChatEnv. Set ECNU_AUTH_SETTING_FILE only when your deployment needs an auth_client setting file; otherwise ChatECNU runs the same bare auth_client check shape as the legacy Precision scripts. The upstream binary appears to accept passwords only through -p PASSWORD; therefore ChatECNU refuses login by default and requires --allow-argv-password / allow_argv_password=True for the legacy wrapper path.

Sensitive values such as passwords, cookies, SMS codes, and session tokens must not be printed or committed.
