Pass basic authentication (SSO/Access Code).\n2. Set the Base URL to a private attack address.\n3. Configure the request method to be a server-side request.\n4. At the self-set attack address, retrieve the API Key information from the request headers.\n\nBackend:\n1. The LobeChat version allows setting the Base URL.\n2.
