How to develop a simple online reservation system using Go language

Under the wave of modern technology, more and more businesses rely on the Internet for operations. One of them is the reservation system, which is widely used in hotels, restaurants, air tickets and other industries. This article will introduce how to use Go language to develop a simple online reservation system.

1. Determine requirements

First of all, we need to clarify what functions our system needs to implement. Generally speaking, a reservation system needs to include the following core functions:

• User registration and login: Users can use the system by registering an account and log in by providing a username and password.
• Booking management: Users can browse the list of bookable items and select and book items of interest.
• Order management: Users can view their order list and manage orders, such as canceling orders, modifying orders, etc.
• Payment function: Users can choose the payment method and complete the order payment.
• Order notification: The system can send order notifications to users, such as payment success, order status changes, etc.

2. Database design

Next, we need to design the database to store related information such as users, projects, and orders. Using a relational database such as MySQL or PostgreSQL is a common choice. In the Go language, you can use an ORM framework such as GORM to simplify database operations.

For example, we can create the following tables to store related data:

• User table (users): stores user login information, personal information, etc.
• Item table (items): stores reservable project information, such as project name, price, inventory, etc.
• Order table (orders): stores the order information booked by the user, such as order number, user ID, project ID, order status, etc.

3. Developing back-end API

Using Go language to develop back-end API is a key step to realize system functions. You can choose to use lightweight web frameworks such as Gin to build API interfaces.

First, we need to implement the user registration and login functions. By receiving the username and password submitted by the user, we can create a new user record in the users table. For the login function, you need to verify whether the username and password submitted by the user match the records in the database. A hash function can be used to calculate the hash value of a password.

Subsequently, we can implement the acquisition and reservation functions of the project list. Users can get a list of projects by sending an HTTP request to the backend API. For the project reservation function, you need to verify the user's identity and create a new order record in the order table.

Finally, we need to implement the order management and payment functions. Users can query, cancel or modify orders by sending HTTP requests to the backend API. As for the payment function, you need to integrate a third-party payment SDK, such as Alipay or WeChat Pay.

4. Developing the front-end interface

By using a front-end framework such as Vue.js or React to develop the front-end interface, we can allow users to interact with the system in a more friendly way. Tools such as Axios can be used to send HTTP requests to the backend API to obtain and submit data.

For example, we can create the following pages to implement the system's functions:

• Login page: Users can enter their username and password to complete the login.
• Homepage: Displays a list of bookable items, and users can select and book items.
• Order page: Displays the user's order list, and the user can view and manage orders.
• Payment page: Displays the payment information of the order and provides payment method selection.

5. Testing and Deployment

After completing the system development, we need to conduct testing to ensure the stability of the system and the accuracy of the functions. Unit testing and integration testing can be used for automated testing of the system.

Finally, we can choose to deploy the system to a server so that users can access it through the Internet. You can use tools such as Docker to containerize applications, and tools such as Nginx for reverse proxy and load balancing.

Summary:

This article briefly introduces how to use Go language to develop a simple online reservation system. By clarifying the requirements, designing the database, and developing the back-end API and front-end interface, we can build a fully functional reservation system, and through testing and deployment, users can easily use the system for reservation operations. Of course, this is just a simple system example. Actual projects may have more functions and requirements, which need to be expanded and customized according to specific circumstances.
