Hey - I've found 1 issue, and left some high level feedback:
- In
BaiduIpLocatorProvider.Fetch, you're only settingLastErroron exceptions; consider also populatingLastErrorwhen the API returns a non-successStatusso callers can distinguish between "no data" and an upstream error. - Swallowing exceptions in
BaiduIpLocatorProvider.Fetchwithout any logging may make diagnosing issues difficult; consider adding some form of logging or telemetry hook in the catch block in addition to settingLastError. - In
Locators.razor.cs,Locationis overwritten byLastErrorwhen an error occurs; it may be clearer to keep location and error separate (e.g., a dedicated error field) so the UI can distinguish between a valid location and an error message.

Please address the comments from this code review:
## Overall Comments
- In `BaiduIpLocatorProvider.Fetch`, you're only setting `LastError` on exceptions; consider also populating `LastError` when the API returns a non-success `Status` so callers can distinguish between "no data" and an upstream error.
- Swallowing exceptions in `BaiduIpLocatorProvider.Fetch` without any logging may make diagnosing issues difficult; consider adding some form of logging or telemetry hook in the catch block in addition to setting `LastError`.
- In `Locators.razor.cs`, `Location` is overwritten by `LastError` when an error occurs; it may be clearer to keep location and error separate (e.g., a dedicated error field) so the UI can distinguish between a valid location and an error message.
## Individual Comments
### Comment 1
<location> `src/BootstrapBlazor.Server/Components/Samples/Locators.razor.cs:72-77` </location>
<code_context>
{
var provider = IpLocatorFactory.Create(ProviderName);
Location = await provider.Locate(Ip);
+
+ if (!string.IsNullOrEmpty(provider.LastError))
+ {
+ Location = provider.LastError;
+ }
}
</code_context>
<issue_to_address>
**🚨 issue (security):** Showing raw LastError messages directly in the UI may expose internal details.
Because `provider.LastError` comes from `ex.Message`, assigning it to `Location` risks exposing internal implementation or infrastructure details to end users. Instead, keep `Location` for location data and surface a generic, user-friendly error message (optionally localized), while logging the detailed error server-side.

Pull request overview
Updates the server-side localization documentation/sample content and extends the IP locator provider API to surface error details from the last lookup.
Changes:
- Adds
LastErrortoIIpLocatorProviderand implements it in the default/base locator provider. - Refines
BaiduIpLocatorProviderresponse parsing and exception handling to setLastError. - Updates the server localization docs/resources and the locator sample to display provider errors.
