如何在golang中使用julienschmidt/httprouter传递两个或多个参数？

Question

我是新来的戈朗，并使用julienschmidt/httprouter路由。基于下面的片段，能够发送一个参数。但我有点困惑，发送多个参数，云任何人帮助我。

package main

import (
    "fmt"
    "github.com/julienschmidt/httprouter"
    "net/http"
    "log"
)

func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
    fmt.Fprint(w, "Welcome!\n")
}

func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
    fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
}

func main() {
    router := httprouter.New()
    router.GET("/", Index)
    router.GET("/hello/:name", Hello)

    log.Fatal(http.ListenAndServe(":8080", router))
}

Answer 1

只需添加另一个参数：

router.GET("/hello/:first_name/:last_name", Hello)

func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
    fmt.Fprintf(w, "hello, %s %s!\n", ps.ByName("first_name"), ps.ByName("last_name"))
}
