Azure example doesn't recognize endpoint URL

[mzattera]

When running the Azure example provided in example folder, I get the below exception.

It seems base URL is not properly recognized.

I have provided both AZURE_OPENAI_KEY and OPENAI_BASE_URL in my environment and I am testing they are read correctly by my app, I get the same error even if I specify the endpoint using:

		OpenAIClient client = OpenAIOkHttpClient.builder()
				.fromEnv()
				.baseUrl("https://<my endpoint>.openai.azure.com/")
				.credential(BearerTokenCredential.create(AuthenticationUtil.getBearerTokenSupplier(
						new DefaultAzureCredentialBuilder().build(), "https://cognitiveservices.azure.com/.default")))
				.build();

I see it says Caused by: java.net.UnknownHostException: www.example.com in your exception. Are you trying to set www.example.com as your base URL via your env? That seems odd.

Hi, no, that's exactly my point. Seems the client is using that URL which is typically used when no URL is set for OkhttpClient (I believe), hence my comment that OpenAIClient is not reading/passing/setting the URL properly.
