In recent years, the development of Web applications has gradually become a hot topic in the IT field. As a highly respected web development language, the emergence of Go language has further enhanced the practicality and efficiency of web development, and the Beego framework makes the web development process faster and simpler. This article will introduce the practice of rapid web development through the Beego framework, allowing readers to understand the basic principles and excellent features of the framework.

Beego is an open source Web framework based on the Go language and widely used on github. The Beego framework is designed based on the MVC framework and provides a series of simple and easy-to-use methods to quickly build web applications and API interfaces. The routing, ORM, log and other modules it provides simplify the web development process and follow excellent coding standards, greatly improving development efficiency.

Before starting to write a specific web application, developers must first create a new project through the Beego framework. After entering the project directory, you can install the required dependencies through the following command:

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

Copy after login

After executing the above command, the dependencies of beego and bee can be automatically installed. The installation and configuration process of the Beego framework is very simple. You only need to run the following command to start the web server locally:

bee run

Copy after login

Through the above command, you can start a default Beego web application. In this application, basic components such as default controllers, models, and views are included to facilitate rapid development.

Next, we will go through this process with an example. Take the user list as an example to demonstrate how to implement a real-time updated user information display page through the Beego framework.

First, we create a controller named "users". In the /controllers directory, create a file named users.go and write the following code:

package controllers

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

type UsersController struct {
    beego.Controller
}

func (c *UsersController) Get() {
    c.TplName = "users.tpl"
    data := []map[string]string{
        {"id": "1", "name": "John", "email": "john@test.com"},
        {"id": "2", "name": "Jane", "email": "jane@test.com"},
        {"id": "3", "name": "James", "email": "james@test.com"},
    }
    c.Data["Users"] = data
}

Copy after login

This controller contains a Get method, which is responsible for processing user requests and returning a view to the user. The TplName attribute specifies the view file used by the template engine, and the Data attribute specifies the data displayed in the view.

Next, create a file named "users.tpl" in the /views directory and write the following code:

{{define "users.tpl"}}
<html>
<head>
    <title>Users info</title>
    <script src="https://unpkg.com/vue"></script>
</head>
<body>
    <div id="app">
        <table>
            <thead>
                <tr>
                    <th>ID</th>
                    <th>Name</th>
                    <th>Email</th>
                </tr>
            </thead>
            <tbody>
                <tr v-for="user in users">
                    <td>{{ user.id }}</td>
                    <td>{{ user.name }}</td>
                    <td>{{ user.email }}</td>
                </tr>
            </tbody>
        </table>
    </div>
    <script>
        new Vue({
            el: "#app",
            data: {
                users: []
            },
            methods: {
                refreshUsers: function () {
                    axios.get("/users").then(response => {
                        this.users = response.data.Users;
                    }).catch(error => {
                        console.log(error);
                    });
                }
            },
            created: function () {
                this.refreshUsers();
                setInterval(this.refreshUsers, 5000);
            }
        });
    </script>
</body>
</html>
{{end}}

This view uses the data binding of Vue.js Customize the template to achieve the effect of updating the user list in real time. The user data is returned through the Get method.

Now we start the Beego server and visit http://localhost:8080/users in the browser to see the page displaying user information.

In summary, the Beego framework provides rapid Web application development and API interface development capabilities, follows excellent coding standards, and has advantages such as high performance and scalability. In this article, we demonstrate through a practical example how to use the Beego framework to implement a real-time updated user information display page. I believe that this article has increased readers' understanding of web development, and the Beego framework should also become one of everyone's first choices, making development faster and more stable.
