How to use Golang to implement an online examination system

Golang is a programming language widely used in back-end development. Its efficiency, reliability and easy maintenance are recognized by more and more developers. In the actual development process, we can use Golang to quickly develop various systems, including examination systems. This article will introduce how to use Golang to implement a simple and easy-to-use online examination system.

First of all, we need to understand the basic requirements of the examination system. The examination system needs to implement the following functions:

1. User login and registration

2. Exam paper management and release

3. Exam answer questions

4. Exam paper Marking and Grade Management

Next, we will introduce how to use Golang to implement these functions in modules.

1. User login and registration

User login and registration are one of the basic functions of any system. We can use Golang's web framework beego to quickly implement user login and registration functions. Beego provides support for common functions such as session and cookie, making it easy to maintain user login status.

2. Test paper management and release

Test paper management and release are the core functions of the examination system. You can use Golang's ORM framework gorm to implement operations such as adding, deleting, modifying, and checking test papers, thereby enabling administrators to manage test papers. At the same time, we also need to implement the test paper publishing function. We can use the file upload function of the beego framework to upload the test paper, or directly store the contents of the test paper into the database.

3. Examination Answers

The core function of the examination system is the examination. We can realize real-time interaction during the examination through Golang's websocket. After the exam starts, the system will push the questions of the test paper to the candidates, and the candidates can answer the questions after receiving them. After the candidate completes the answer, the marking system will mark the test based on the candidate's answer, calculate the candidate's score, and store the test results in the database.

4. Test paper marking and score management

Test paper marking and score management are the last steps to implement the examination system. Administrators can query test results through the system and review and modify candidates' answers. At the same time, the system can also support functions such as exporting test scores.

To sum up, we can quickly develop a simple and easy-to-use online examination system through Golang. Golang's efficient, reliable and easy-to-maintain features can greatly improve the development efficiency and stability of the system, and provide high-quality examination solutions for various enterprises, schools, training institutions, etc.
