Original Pull Request: https://github.com/langgenius/dify/pull/23008

State: closed
Merged: Yes

nent

  • Fix #22880: Missing boundary when using multipart/form-data
  • Improve Content-Type header handling for multipart requests
  • Add robust UTF-8 decoding for file content in logs
  • Support multiple file types (text, binary, Chinese content)
  • Ensure httpx correctly generates boundary when files are present

The fix ensures that:

  1. Boundary is properly generated and included in request body
  2. Content-Type header is correctly set for different scenarios
  3. File content decoding handles both text and binary files gracefully
  4. All file types are supported without encoding errors
