Go语言API网关：统一入口与路由

Go语言API网关统一入口与路由1. API网关概述API网关作为微服务的统一入口提供路由、认证、限流等功能。2. 网关实现package gateway import ( github.com/gin-gonic/gin ) type Gateway struct { router *gin.Engine services map[string]*ServiceConfig } type ServiceConfig struct { URL string Routes []Route } type Route struct { Path string Method string Target string } func NewGateway() *Gateway { return Gateway{ router: gin.Default(), services: make(map[string]*ServiceConfig), } } func (g *Gateway) AddService(name string, config *ServiceConfig) { g.services[name] config } func (g *Gateway) Build() *gin.Engine { for name, svc : range g.services { group : g.router.Group(/ name) for _, route : range svc.Routes { group.Handle(route.Method, route.Path, func(c *gin.Context) { c.Redirect(http.StatusMovedPermanently, svc.URLroute.Target) }) } } return g.router }3. 总结API网关是微服务架构的核心组件可以简化客户端调用统一处理横切关注点。
