如何处理来自 go 的请求方法。我不使用图书馆

Question

在此之前我使用 node js 并且很容易理解如何处理方法节点 js 上的示例：    switch (request.method) {    case 'OPTIONS': return OptionsResponse(response);    case 'GET': return GetSwitch(request, response);    case 'POST': return PostSwitch(request, response);    case 'PUT': return PutSwitch(request, response);    case 'DELETE': return DeleteSwitch(request, response);    default: return ErrorMessage( "Sorry, this method not supported", 501, request);}但我不知道该怎么做package utilsimport (    "log"    "net/http"    "github.com/user/go_rest_api/src/view" // page view    "github.com/user/go_rest_api/src/api" // only api server);如何在 go 中实现相同的处理程序？func HandlerRequestFunc() {http.HandleFunc("/", view.Homepage);/*get method from api server */http.HandleFunc("/api", api.InfoFromApi);/* from db api handler */http.HandleFunc("/api/login", api.Login);http.HandleFunc("/api/registration", api.Registration);/* get your list db */http.HandleFunc("/api/db/list", api.DataBaseList);/* server start function */log.Fatal(http.ListenAndServe(":3000", nil));}如何不在函数内部处理方法

Answer 1

也许这可以帮助你：

type MyHandler struct{}

func (self MyHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {

}

http.ListenAndServe(":3000", &MyHandler{})

Answer 2

这是翻译成 Go 的问题中的 node.js 代码。Go 代码与 node.js 代码非常相似。

func myHandler(response http.ResponseWriter, request *http.Request) {

    switch request.Method {

    case "OPTIONS":

        OptionsResponse(response, request)

    case "GET":

        GetSwitch(response, request)

    case "POST":

        PostSwitch(response, request)

    case "PUT":

        PutSwitch(response, request)

    case "DELETE":

        DeleteSwitch(response, request)

    default:

        http.Error(response, "Sorry, this method not supported", 501)

    }

}

Answer 3

我认为您需要像这样为您的代码编写响应和请求。因为是语言的默认包

func myHandler(w http.ResponseWriter, r *http.Request) {

switch request.Method {

case "OPTIONS":

    OptionsResponse(response, request)

case "GET":

    GetSwitch(response, request)

case "POST":

    PostSwitch(response, request)

case "PUT":

    PutSwitch(response, request)

case "DELETE":

    DeleteSwitch(response, request)

default:

    http.Error(response, "Sorry, this method not supported", 501)

}

}
