Contributed to the alibaba/fastjson2 repository by enhancing JSON parsing capabilities for embedded binary data. Developed and integrated Base64 Data URI handling within ObjectReaderImplInt8ValueArray, enabling the parser to automatically strip data URI prefixes such as 'data:image/jpeg;base64,' and accurately decode the underlying Base64 content. This approach reduced the need for manual preprocessing and improved the reliability of decoding binary data embedded in JSON payloads. Comprehensive unit tests were added to validate the new functionality and ensure robust coverage. The work demonstrated proficiency in Java, JSON parsing, and unit testing, with all changes prepared for review and integration.
