Golang 関数ライブラリのインストールと使用ガイド

// 安装 github.com/gorilla/mux 路由函数库
go get github.com/gorilla/mux

import "github.com/gorilla/mux"

func main() {
    router := mux.NewRouter()
}

package main

import (
    "fmt"
    "log"
    "net/http"
    "github.com/gorilla/mux"
)

func main() {
    // 创建路由器
    router := mux.NewRouter()
    router.HandleFunc("/users", getUsers).Methods(http.MethodGet)
    router.HandleFunc("/users/{id}", getSingleUser).Methods(http.MethodGet)

    // 启动 HTTP 服务器
    http.Handle("/", router)
    log.Fatal(http.ListenAndServe(":8080", nil))
}

func getUsers(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Get all users")
}

func getSingleUser(w http.ResponseWriter, r *http.Request) {
    id := mux.Vars(r)["id"]
    fmt.Fprintf(w, "Get user with ID: %s", id)
}
