This article explains how to design a unified API response format in backend development, covering JSON structure, status‑code conventions, controller refactoring, annotation‑based response wrapping, and practical implementation steps to achieve clean, maintainable, and user‑friendly API outputs.
This guide explains how to implement API request signatures, encrypt sensitive data using SM4, and standardize response structures, providing step‑by‑step instructions, code examples in PHP, and security best practices to protect API integrity and confidentiality.
The discussion compares two API response designs—always returning an empty array for field B versus omitting B when it has no data—and evaluates which approach provides clearer contracts and easier handling for front‑end developers.
This article explains how to create a consistent JSON response structure for Java backend APIs, covering status‑code conventions, a Result wrapper class, static helper methods, a custom @ResponseResult annotation, response‑body advice, and tips for simplifying controller code and handling exceptions.
