Go Web 开发框架
chi is a lightweight, idiomatic and composable router for building Go HTTP services. It's especially good at helping you write large REST API services that are kept maintainable as your project grows and changes. chi is built on the new context package introduced in Go 1.7 to handle signaling, cancelation and request-scoped values across a handler chain.
Package gorilla/mux implements a request router and dispatcher for matching incoming requests to their respective handler.
