Worked on the cloudwego/eino-ext repository to implement an embedding authentication enhancement that supports project-specific authentication across embedding endpoints. The solution introduced a ProjectName field to the EmbeddingConfig, ensuring that project information is consistently propagated through CreateEmbeddings and CreateMultiModalEmbeddings requests. By integrating the WithProjectName option, the update enabled automatic AK/SK authentication headers for preset endpoints requiring a project name, reducing manual header management and aligning with security requirements. The work focused on backend development using Go and API development practices, addressing authentication gaps and improving compliance for embedding workflows without introducing new bugs during the development period.
