How to handle these routes: /example/log and /example/:id/log?
问题
我尝试了类似这样的代码：
router.GET("/example/log", logAllHandler)
router.GET("/example/:id/log", logHandler)
但是 Gin 不允许这样做，并在启动时出现错误。

我已经成功完成了。希望这对你有所帮助：
package main
import (
"fmt"
"github.com/julienschmidt/httprouter"
"log"
"net/http"
)
func logAll(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
if ps.ByName("id") == "log" {
fmt.Fprintf(w, "Log All")
}
}
func logSpecific(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
fmt.Fprintf(w, "Log Specific, %s!\n", ps.ByName("id"))
}
func main() {
router := httprouter.New()
router.GET("/example/:id", logAll)
router.GET("/example/:id/log", logSpecific)
log.Fatal(http.ListenAndServe(":8081", router))
}
运行示例：
$ curl http://127.0.0.1:8081/example/log
Log All
$ curl http://127.0.0.1:8081/example/abc/log
Log Specific, abc!
