Question

我是golang的新手，并使用julienschmidt / httprouter进行路由。基于以下片段，能够发送一个参数。但我很困惑发送多个参数，云有人帮助我。

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"))
}

如何在golang中使用julienschmidt / httprouter传递两个或更多参数？
