📄️ 4.1 Preface

Programmers' core skills CRUD operations complete word management through Create, Read, Update, and Delete operations. RESTful is a design principle for implementing simple and flexible web service architecture for resource management, using URIs to access resources and ensuring communication between systems through HTTP methods such as GET, POST, PUT, PATCH, and DELETE.

📄️ 4.2 Data Model

Create a new data table to save word information and add a unique index to prevent users from adding duplicates. Generate a data model and customize the ProficiencyLevel type to represent word proficiency, defining five levels. This use of fixed enumeration values improves code readability and maintainability, applicable to various state scenarios.

📄️ 4.3 Add Word

Implement a RESTful-style word creation API using the GoFrame framework, including the division of responsibilities between the API layer and the logical layer in the architecture design, emphasizing that data structures should not be passthrough. Detailed explanation on how to ensure data consistency in the logical layer and avoid duplicate input, and how to call multi-layer logic in the controller to maintain single functionality. Additionally, covers the method of controller route registration and interface testing.

📄️ 4.4 Edit Word

Utilize the REST API in the GoFrame framework to update word information, including the word's definition, example sentences, Chinese translation, and pronunciation. Emphasizes the uniqueness check and permission verification logic during edit operations, and demonstrates how to use the database to update data and handle errors through code examples.

📄️ 4.5 Word Pagination

Retrieve a paginated list of words using the GET method with fuzzy search functionality. Define a structure to store word fields, including ID, word, definition, and proficiency level. Write Logic in the GoFrame framework for querying and paginating data operations. Invoke Logic through the Controller to achieve data retrieval and return, supporting comprehensive interface testing.

📄️ 4.6 Word Detail

The word detail interface obtains detailed information of a word not in the list through a GET request, including fields such as example sentence, Chinese translation, and pronunciation. It uses fuzzy routing to match and implements database query operations through the logic layer of the interface.

📄️ 4.7 Delete Word

Implement word deletion functionality through API using DELETE method to request the deletion of a word with a specified ID. The Logic layer performs database deletion operations based on user ID and word ID, while the Controller layer handles the request and calls the logic to delete the word. Detailed interface testing steps are provided to verify the functionality implementation.

📄️ 4.8 Summary

Developing word management functions based on RESTful, including creating, reading, updating, and deleting words, implementing enumeration value management status, using a layered data model for data operations, supporting optimization techniques for composite indexes, pagination, and fuzzy queries.
