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:
1 2 |
|
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:
1 |
|
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:
1 |
|
By default, the default listening port is 8080. If we need to change the port, we can use the following command line:
1 |
|
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:
1 |
|
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:
1 |
|
After generating the code, we open the controller file (under the controllers folder) and find IndexController , and edit the method:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
|
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:
1 2 3 4 5 6 7 8 9 10 |
|
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:
1 2 3 4 5 6 7 8 |
|
Then, in the Get method of IndexController, you can modify the code and output the defined template, as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
|
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.

Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.
Golang framework vs. Go framework: Comparison of internal architecture and external features
Jun 06, 2024 pm 12:37 PM
The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.
How to save JSON data to database in Golang?
Jun 06, 2024 am 11:24 AM
JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.
How to find the first substring matched by a Golang regular expression?
Jun 06, 2024 am 10:51 AM
The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].
