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 utils

import (

    "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)}}
