Quickly build web applications using Golang's web framework beego
With the development and popularization of Internet technology, there are more and more demands for Web applications. Building Web applications quickly and efficiently has become an urgent need for developers. Golang's dynamic characteristics, efficient execution capabilities and rich web frameworks have become the first choice for many developers.
Among many Golang web frameworks, beego is a fast, concise, efficient and easy-to-use web framework. It relies on Go's native HTTP package, has RESTful support, MVC mode, and comes with its own ORM and template engine. and many other powerful features.
In this article, we will introduce how to use beego to quickly build a simple web application.
1. Install beego and bee
First, we need to install beego and bee tools, which can be achieved in the command line through the following command:
go get -u github.com/astaxie/beego go get -u github.com/beego/bee
After installation, We can create a new project using the bee tool. Enter your favorite development folder on the command line and type the following command:
bee new project_name
The project_name here can be named by yourself, and a new folder named project_name will be created.
2. Run the beego service
After completing the project creation, we need to run the beego service in the project directory. We can use the bee tool to easily start the beego server:
bee run
By default, the default listening port is 8080. If we need to change the port, we can use the following command line:
bee run -p <your_port>
3 , Create Controller
In the beego framework, requests and responses can be easily processed through the controller. We can quickly create a Controller through the bee tool, just type the following command in the project directory:
bee generate controller <controller_name>
Among them, controller_name is the name of the controller that needs to be created. For example, we need to create a controller called IndexController:
bee generate controller Index
After generating the code, we open the controller file (under the controllers folder) and find IndexController , and edit the method:
package controllers
import (
"github.com/astaxie/beego"
)
type IndexController struct {
beego.Controller
}
func (c *IndexController) Get() {
c.Ctx.WriteString("Hello, world!")
}In the Get method, we send a simple "Hello, world!" message to the user.
At this point, we have created a basic controller to handle Hello world requests.
4. Create Router
Next, we need to route the request to the controller for processing, which can be achieved through Router.
In the beego framework, Router can define routing rules through class objects. We can define the corresponding routing rules by creating the router.go file under the routers folder. First register the IndexController:
package routers
import (
"github.com/astaxie/beego"
"project_name/controllers"
)
func init() {
beego.Router("/", &controllers.IndexController{})
}Among them, the beego.Router method is used to define routing rules, and the first parameter is the URL. , the second parameter is Controller.
5. Run the Web application
We have completed the process of creating controllers and routes, and now we can access the routes we just defined in the browser. Start the beego server on the command line, open the browser, enter http://localhost:8080/, and we will see the "Hello, world!" page.
6. Add a view template
In addition to outputting strings in the controller, beego also supports using the built-in template engine to output HTML pages. We can create a view template of index.tpl in the views folder, the code is as follows:
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1 id="">{{.}}</h1>
</body>
</html>Then, in the Get method of IndexController, you can modify the code and output the defined template, as follows:
package controllers
import (
"github.com/astaxie/beego"
)
type IndexController struct {
beego.Controller
}
func (c *IndexController) Get() {
c.Data["Website"] = "beego.me"
c.Data["Email"] = "astaxie@gmail.com"
c.Data["Message"] = "Hello, world!"
c.TplName = "index.tpl"
}In Data, we have defined three key-value pairs, namely website address, email address and message. Then, set TplName to the name of the template file so that when the user accesses the URL, the HTML page is automatically rendered.
7. Summary
This article introduces developers to how to use beego to quickly build web applications. First install beego and bee tools, then create a new project using bee tools. Next, handle the request and response in the Controller, register the controller in the Router and specify routing rules. Finally, the HTML page is rendered in the view using beego's built-in template engine. Using beego, you can quickly build high-performance web applications to better meet user needs.

The Performance Race: Golang vs. CApr 16, 2025 am 12:07 AMGolang and C each have their own advantages in performance competitions: 1) Golang is suitable for high concurrency and rapid development, and 2) C provides higher performance and fine-grained control. The selection should be based on project requirements and team technology stack.
Golang vs. C : Code Examples and Performance AnalysisApr 15, 2025 am 12:03 AMGolang is suitable for rapid development and concurrent programming, while C is more suitable for projects that require extreme performance and underlying control. 1) Golang's concurrency model simplifies concurrency programming through goroutine and channel. 2) C's template programming provides generic code and performance optimization. 3) Golang's garbage collection is convenient but may affect performance. C's memory management is complex but the control is fine.
