Use DELETE HTTP Method in GoLang RESTful Web API

Install Libraries

Make sure Git is installed on your machine and in your system’s PATH. Install the packages to your $GOPATH with the go tool from shell:

$ go get -u github.com/gorilla/mux
$ go get -u github.com/gorilla/handlers

Web APIs

In src folder, create new folder named apis. In this folder, create new web api as below:

Product API

In apis folder, create new folder named productapi. In productapi folder, create new go file named product.api.go as below:

package productapi

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

	"github.com/gorilla/mux"
)

type ResponseResult struct {
	Id string `json:"id"`
}

func Delete(response http.ResponseWriter, request *http.Request) {
	vars := mux.Vars(request)
	id := vars["id"]
	respondWithJSON(response, http.StatusOK, ResponseResult{Id: id})
}

func respondWithJSON(response http.ResponseWriter, statusCode int, data interface{}) {
	result, _ := json.Marshal(data)
	response.Header().Set("Content-Type", "application/json")
	response.WriteHeader(statusCode)
	response.Write(result)
}

Structure of Project

Run Application

In src folder, create new file named main.go as below and use go run main.go command to run program:

package main

import (
	"apis/productapi"
	"fmt"
	"net/http"

	"github.com/gorilla/mux"
)

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

	router.HandleFunc("/api/product/delete/{id}", productapi.Delete).Methods("DELETE")

	err := http.ListenAndServe(":3000", router)
	if err != nil {
		fmt.Println(err)
	}
}

Test Web API

Use PostMan Tool test web api with url: http://localhost:3000/api/product/delete/p01
