Golang을 사용하여 RESTful API를 구축하고 JSON 응답을 처리하는 방법은 무엇입니까?

go mod init <project-name>

go get github.com/gorilla/mux

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

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/", HomeHandler).Methods("GET")
    // ... 其他路由定义
    http.ListenAndServe(":8080", router)
}

func HomeHandler(w http.ResponseWriter, r *http.Request) {
    // 根据请求方法处理请求
    switch r.Method {
    case "GET":
        // ... 处理 GET 请求
    case "POST":
        // ... 处理 POST 请求
    // ... 其他方法处理
    }
}

go get github.com/json-iterator/go

import (
    "encoding/json"
    "fmt"
    "net/http"
)

func WriteJSONResponse(w http.ResponseWriter, data interface{}) {
    w.Header().Set("Content-Type", "application/json")
    if err := json.NewEncoder(w).Encode(data); err != nil {
        // 处理错误
    }
}

router.HandleFunc("/users", GetAllUsersHandler).Methods("GET")
