Original Pull Request: https://github.com/langgenius/dify/pull/23474

State: closed
Merged: Yes

The HTTP node was appending an unexpected '=' sign to query parameters, which caused the backend API to reject the request or return incorrect results.

This fix prevents adding '=' when parameters are empty or not needed, ensuring the HTTP request matches the remote endpoint expectations.

Fixes #23385

Results

self-backend log
before: "GET /xxx/xxx.do?checkuser= HTTP/1.1"
after: "GET /xxx/xxx.do?checkuser HTTP/1.1"

Summary

Fixes the issue where the HTTP node added an extra '=' sign at the end of query parameters when they were empty or missing. This caused incorrect API requests and failed responses.

The fix changes parameter defaults to 'None'(instead of []) to skip appending '=' when the value is empty.
