Unified payment gateway system based on intelligent payment routing

The invention provides a unified payment gateway system based on intelligent payment routing, and solves the problems that routing rule maintenance is very tedious and the effect is not expected by providing multiple routing modes, manual routing, rule routing and automatic routing. routing is performed to an optimal channel for payment according to a preset rule, classification processing is performed according to error categories after payment failure, rerouting operation is automatically performed on part of the orders, and available channels for continuous payment are automatically switched; and when all available channels fail, the order is marked as fail, and the payment success rate can be improved through rerouting processing. Performance and stability are improved by adopting a large number of asynchronization modes, distributed services are supported, and corresponding service protection capacity is achieved. The system encapsulates a three-party payment channel externally and provides a unified pay
