Custom-built Nezha panel doesn't show flag. Noob慎入.

admin

Because you can customize the interface and functions;
Lazy people directly move to the official website;
As agent continues to update, I don't know what has changed, and it doesn't display the flag all the time today, so I manually coded the code for geolocation query service/rpc/nezha.go
Find the LookupGeoIP method in the code
Directly modify the code below code and compile it
