4.2 mux 使用bug

1. 运行环境

win10/go 1.19

2. 问题描述？

• mux这段代码可能已经过时

  homeURL, _ := router.Get("home").URL()
  fmt.Println("homeURL: ", homeURL)

• router.Get返回的是*Router，其结构为

  type Route struct {
    // Request handler for the route.
    handler http.Handler
    // If true, this route never matches: it is only used to build URLs.
    buildOnly bool
    // The name used to build URLs.
    name string
    // Error resulted from building a route.
    err error
  
    // "global" reference to all named routes
    namedRoutes map[string]*Route
  
    // config possibly passed in from `Router`
    routeConf
  }

  这里要获取的是name，可以通过GetName方法拿到Router的name，所以应该为

  homeURL := router.Get("home")
  fmt.Println("homeURL：", homeURL.GetName())
