Product name (e.g. "快代码科技工作室 100 元") should show the user's
original recharge amount (limitAmount), not the fee-inclusive pay amount.
The gateway receives payAmount separately for actual charging.
Backend:
- Use cfg.RechargeFeeRate in order creation instead of hardcoded 0
- Remove dead getFeeRate stub method
- All amounts computed server-side: order_amount, pay_amount, fee_rate
Frontend - PaymentView:
- Read recharge_fee_rate from checkout-info API (not per-method)
- Show fee breakdown only when fee_rate > 0
- Show credited amount only when multiplier ≠ 1
Frontend - Order display (user + admin):
- Fix fee_rate * 100 bug (fee_rate is already a percentage)
- OrderTable: show pay_amount as primary, fee/credited as sub-lines
- AdminOrderDetail: full breakdown (base/fee/paid/credited)
- AdminRefundDialog: label "到账金额" for clarity
- PaymentResultView: show pay_amount with fee info
Types + i18n:
- Add recharge_fee_rate to CheckoutInfoResponse
- Add fee_rate to CreateOrderResult
- Add translations: creditedAmount, fee, baseAmount, includedInPayAmount
Two issues fixed:
1. Alipay.SupportedTypes() returned ["alipay_direct"] and Wxpay returned
["wxpay_direct"], but the frontend sends payment_type="alipay"/"wxpay".
The registry lookup failed with "payment method (alipay) is not
configured". Fix: return the base types ["alipay"]/["wxpay"].
2. When multiple providers support the same payment type (e.g. EasyPay
and Alipay direct both handle "alipay"), only the last-registered
provider's instances were reachable — the registry mapped one type to
one provider key, and SelectInstance queried by that single key.
Fix: bypass the registry in invokeProvider and let SelectInstance
query across all providers when providerKey is empty. The selected
instance's own ProviderKey (now included in InstanceSelection) is
used to create the correct provider, enabling true cross-provider
load balancing.
Closes#1592
Add a full payment and subscription system supporting EasyPay (Alipay/WeChat),
Stripe, and direct Alipay/WeChat Pay providers with multi-instance load balancing.
