How to use go language for web development

The web development process of Go language is: 1. Select a web framework; 2. Design routing and specify how URLs are mapped to handlers; 3. Process requests and responses, including parsing request parameters, processing form data, and setting Cookies, etc.; 4. Database operation, storing data in the database; 5. Template rendering, presenting data to users using a template engine to generate HTML pages; 6. Deployment and operation, deploying the application to the server and running it.

The Go language can be used for Web development. Here is a brief introduction to the Web development process of the Go language:

1. Choose a Web framework: The Go language has many Web frameworks to choose from. , including Gin, Beego, Echo, etc. These frameworks provide a series of tools and functions to help developers quickly build web applications.

2. Design routing: Routing is the foundation of web applications. It specifies how URLs are mapped to handlers. In Go, the HTTP standard library is generally used to handle routing, or the routing components provided by the web framework can be used.

3. Processing requests and responses: The standard library of the Go language provides many functions for processing HTTP requests and responses, including parsing request parameters, processing form data, setting cookies, etc.

4. Database operation: If you need to store data in a database, Go language also provides a series of database operation libraries, including SQL databases and NoSQL databases, such as MySQL, PostgreSQL, MongoDB, etc. wait.

5. Template rendering: Web applications usually need to present data to users, which requires the use of a template engine to generate HTML pages. The Go language template engine is very flexible and supports custom functions and variables.

6. Deployment and running: After the application development is completed, the application needs to be deployed to the server and run. Go binaries are very small and can be easily deployed on a server or using tools such as Docker.

In short, you can easily use Go language for web development by choosing a web framework, designing routing, processing requests and responses, database operations, template rendering and other steps. It is recommended that you first master the basic knowledge of the Go language and be familiar with the HTTP-related functions in the standard library before starting to develop using a web framework.
