how to handle request method from go. I don't use libraries-CodePudding

before that I worked with node js and it was easy to understand how to handle methods

example on node js:

    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);

}

but in go i can't figure out how to do it

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
);

How can I implement the same handler in go?

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));

}

how not to process a method inside a function

CodePudding user response：

Here's the node.js code in the question translated to Go. The Go code is very similar to the node.js code.

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)
    }
}

CodePudding user response：

i think you need wiriting response and request for your code like this. because is the default package of the language

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)
}

}
