How to use Golang to build a RESTful API and use logging

Introduction

Building a RESTful API is a common task for Go developers. Logging is also crucial for any application. This article will guide you in building a basic RESTful API using Golang and introduce how to implement logging.

Prerequisites

  • Go 1.18 or higher
  • Text Editor or IDE

Create Project

Create a new Go project:

go mod init golang-restful-api

Build API

1. Routing

Create a new filerouter.go, which contains the route to handle the request:

package main

import (
    "github.com/gin-gonic/gin"
)

func main() {
    router := gin.Default()

    router.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })

    router.Run()
}

2. Start the API

In the main function, gin.Engine is instantiated and a route handler is added that handles GET requests from the /ping route. It will return message "pong".

Logging

1. Configure logging

Create a new filelogger.go, which contains logging configuration:

package main

import (
    "log"
    "os"
)

var logger = log.New(os.Stdout, "", 0)

2. Using logging

In the API handler, use logger to log information:

func main() {
    // ...

    router.GET("/ping", func(c *gin.Context) {
        logger.Println("Received ping request")
        // ...
    })
}

Practical case

Use curl to test the API:

curl http://localhost:8080/ping

This will output the following log record:

Received ping request
