Original Pull Request: https://github.com/langgenius/dify/pull/1551

State: closed
Merged: Yes

The purpose of this PR is to fix an issue that fetch stream feature would not work because of compatibility.

Steps to reproduce

  • Use the QQ iOS app
  • browser any dify demo app
  • try to send any word and we won't get any reply

The implementation approach is:

Detect browser version, and do not use fetch streams for older browsers

  • For older browsers, use traditional request mode for chatting
  • For newer browsers, continue using fetch streams
