在 Admin.Core 中使用 Redis 实现接口限流

Imagine a digital fortress where every request is meticulously counted, not in isolation, but as part of a grand, synchronized symphony across multiple servers. The premise of distributed rate limiting often sounds like a complex engineering hurdle, yet it can be elegantly solved by harnessing the power of Redis to create a unified memory space for traffic control. When an application scales horizontally, adding more instances usually fractures data consistency, but what if every node could peek into the same real-time ledger? This approach transforms the chaos of distributed systems into order, ensuring that no single user can overwhelm the infrastructure regardless of which server they land on. The mechanics are deceptively simple: a key is generated from the client’s identity and endpoint, incremented atomically in Redis, and checked against a threshold before the request ever touches the business logic. If the limit is breached, a crisp 429 status code halts the process, protecting...--AI Generated
