Introduction to Beego framework in Go language

Beego is a Go language web framework based on MVC architecture. It provides a complete set of solutions to simplify the development of web applications. Beego has many built-in functional modules, such as routing, ORM, Session, etc., and also provides many powerful tools and auxiliary functions, allowing developers to develop web applications more efficiently.

Install the Beego framework

First, we need to install the Beego framework in the Go language environment. Installing Beego is very simple, just run the following command in the terminal:

go get -u github.com/astaxie/beego
go get -u github.com/beego/bee

This will install the Beego framework and its command line tool bee.

Create a simple Beego application

Next, let us create a simple Beego application. First, execute the following command to create a new Beego application in the current directory:

bee new hellobeego

This will create a new Beego application named hellobeego in the current directory.

Writing Controller

Next, we need to create a controller to handle HTTP requests. In Beego, controllers are usually placed in the controllers directory. We create a controller named MainController:

package controllers

import (
    "github.com/astaxie/beego"
)

type MainController struct {
    beego.Controller
}

func (c *MainController) Get() {
    c.Ctx.WriteString("Hello, Beego!")
}

In the above code, we define Create a MainController controller, process the GET request in the Get method, and return the Hello, Beego! string to the client.

Define routing

In Beego, routing is configured through the routers file in the conf directory. We open the routers file, define a routing rule, and map the / path to the MainController controller:

package routers

import (
    "hellobeego/controllers"
    "github.com/astaxie/beego"
)

func init() {
    beego.Router("/", &controllers.MainController{})
}

Run the application

Finally, we run our Beego application through the following command:

bee run hellobeego

After successful operation, we visit http://localhost:8080 in the browser, and it will See the output Hello, Beego!.

Summary

Through the above simple example, we have learned how to create a simple application in the Beego framework, including writing controllers, defining routes and running the application. The Beego framework provides many features and tools to help developers develop web applications more efficiently. I hope this article will be helpful to you about the Beego framework.
