Closes: #12061

Description

This PR attempts to address Issue #12061 where the Qwen Code provider fails with "400 bad request" for users with newer Qwen Code CLI versions (v0.14.2+).

Root Cause: The Qwen Code CLI v0.14.2+ now sets resource_url in ~/.qwen/oauth_creds.json to portal domains like portal.qwen.ai (international) or chat.qwen.ai (China). The handler was using this value directly as the API base URL, resulting in requests going to https://portal.qwen.ai/v1 instead of the correct Dashscope API endpoint. Additionally, the OAuth token refresh endpoint was hardcoded to chat.qwen.ai, which fails for international portal users.

Fix:

  • Added a QWEN_PORTAL_CONFIG mapping that maps known portal domains to their corresponding Dashscope API base URLs and OAuth token endpoints:
    • portal.qwen.ai -> dashscope-intl.aliyuncs.com (international) with OAuth via portal.qwen.ai
    • chat.qwen.ai -> dashscope.aliyuncs.com (China) with OAuth via chat.qwen.ai
  • The getBaseUrl method now checks if resource_url matches a known portal domain before using it as-is
  • Added getOAuthTokenEndpoint method to derive the correct token endpoint from the credentials resource_url
  • If resource_url is already a full dashscope URL (backward compatibility), it is used directly

Test Procedure

  • Added 8 new tests in qwen-code-portal-mapping.spec.ts covering:
    • portal.qwen.ai maps to dashscope-intl API endpoint
    • chat.qwen.ai maps to dashscope China API endpoint
    • Missing resource_url falls back to default dashscope URL
    • Existing dashscope URLs in resource_url are preserved
    • portal.qwen.ai with https:// prefix is handled correctly
    • OAuth token endpoint correctly derived for each portal domain
  • All existing qwen-code-native-tools.spec.ts tests continue to pass
  • Run: cd src && npx vitest run api/providers/__tests__/qwen-code-portal-mapping.spec.ts

Additional Notes

Feedback and guidance are welcome. The portal-to-API mapping is based on the observed pattern from Qwen Code CLI v0.14.2 credentials. If additional portal domains emerge, they can be added to the QWEN_PORTAL_CONFIG mapping.

The Qwen Code CLI v0.14.2+ sets resource_url to portal domains like
"portal.qwen.ai" instead of Dashscope API URLs. The handler was using
this value directly as the API base URL, causing 400 errors.

Changes:
- Add QWEN_PORTAL_CONFIG mapping for known portal domains to their
  corresponding Dashscope API and OAuth token endpoints
- portal.qwen.ai -> dashscope-intl.aliyuncs.com (international)
- chat.qwen.ai -> dashscope.aliyuncs.com (China)
- Derive OAuth token endpoint from resource_url instead of hardcoding
  chat.qwen.ai, so international users hit the correct token server
- Add comprehensive tests for URL mapping behavior

Hello guys,

I've tried to compile .vsix file from this branch and install it directly to the VS Code and I faced another problem with refreshing token. I tried also to reinstall qwen code plugin and execute Roo again, it didn't help.

Error details from Roo console:
{
"error": {
"timestamp": "2026-04-15T20:52:03.494Z",
"version": "3.54.0", ### was changed by me
"provider": "qwen-code",
"model": "qwen3-coder-plus",
"details": "Token refresh failed: 404 Not Found. Response:"
},
"history": [
{
"role": "user",
"content": [
{
"type": "text",
"text": "<user_message>\nHello world\n</user_message>"
},
{
"type": "text",
"text": "<environment_details>some_env_details</environment_details>"
}
],
"ts": 1776286314267
}
]
}

Thanks in advance
Hope it would help
