Hey - I've found 2 issues, and left some high level feedback:
- In
ApiConfigUpdatethecurrentBackendfield is never used inupdate_api_config; consider either wiring it into the logic (e.g., for validation or migration) or removing it to avoid confusion about its purpose. - In
update_api_configafter successfully settingfrontend_backend_urlyou don't return any explicit success payload, so clients will receive anullJSON body; consider returning a simple{ "success": true }(and possibly the saved URL) for clearer client handling and consistency with other endpoints.

Please address the comments from this code review:
## Overall Comments
- In `ApiConfigUpdate` the `currentBackend` field is never used in `update_api_config`; consider either wiring it into the logic (e.g., for validation or migration) or removing it to avoid confusion about its purpose.
- In `update_api_config` after successfully setting `frontend_backend_url` you don't return any explicit success payload, so clients will receive a `null` JSON body; consider returning a simple `{ "success": true }` (and possibly the saved URL) for clearer client handling and consistency with other endpoints.

**suggestion:** The `currentBackend` field in `ApiConfigUpdate` is defined but never used in the endpoint logic.
Since only `backendUrl` and `secret` are read in `update_api_config`, consider removing `currentBackend` to keep the model minimal. If you plan to use it later, either wire it into the current logic now or introduce a dedicated DTO when that logic is added.
Suggested implementation:
```python
class ApiConfigUpdate(BaseModel):
backendUrl: str | None = None
secret: str | None = None
```
1. Search the codebase for any remaining references to `currentBackend` (e.g. in request bodies, tests, or frontend code) and remove or adjust them accordingly.
2. If this API is consumed externally, consider whether this is a breaking change; if so, update API documentation and any client DTOs to match.

**issue (bug_risk):** Authentication failures against the target backend are treated as connectivity failures, which can mislead users.
The connectivity check currently treats any `r.status_code >= 400` as a network error and returns `"无法连接目标后端"`. For backends that require their own credentials, a 401/403 still proves the URL is reachable, but the message implies a connectivity problem instead of an auth issue. Consider either treating any HTTP response as a successful connectivity check and only handling transport-level failures, or special-casing 401/403 (and possibly other 4xx) with a more accurate error message to avoid confusing users for protected backends.
