Server:
- New lib/wxpay.js: native crypto RSA-SHA256 signing, JSAPI prepay,
AES-256-GCM notify decryption, order query (no npm deps)
- New dao/payment-order.dao.js: createOrder, markPrepay,
markPaidAndActivateSubscription (idempotent + transactional)
- New routes/payment.js: GET order status, POST order sync
- New routes/payment-notify.js: WeChat async callback handler with
signature verification, amount/appid/mchid validation
- Modified subscription/purchase: auto-detects wxpay config, returns
real payment_params or mock fallback
- Schema: payment_orders table with out_trade_no unique key
- app.js: express.raw() for notify path, payment routes mounted
- config.js: wxpay block with 7 env vars
- .env.example: all WeChat Pay fields documented
- .gitignore: certs/, *.pem, *.p12
Miniprogram:
- subscribe-plans doPurchase: calls real purchase API, falls back to
mockPurchase only when server returns mock:true
- Added syncAndRedirect for post-payment order confirmation
- api.js: getPaymentOrder, syncPaymentOrder
- Removed "模拟支付"/"测试环境" from UI text
- Login bcrypt migration: write password_salt = '' instead of NULL,
which violated the NOT NULL constraint and caused 500 errors
- Schema: widen password_hash from CHAR(64) to VARCHAR(100) for bcrypt
compatibility, add DEFAULT '' to password_salt
- init-db: add ALTER TABLE migrations for existing databases
- app.js: enrich error logging with method, path, SQL error details
