Make BASE_URL customizable

[guyutongxue]

Problem

I prefer not using OpenAI's official API endpoint https://api.openai.com/v1/, but some mirror site like chatanywhere/GPT_API_free.

Solution

Seems that this feature is easy to implement, just make BASE_URL in lib.rs customizable -- export a function like set_key; for example set_base_url.

Alternatives

No response

Would you like to have a go at implementing this?

FYI I'll have some time to work on this (and any other open issues) only in a month or so.
If anyone can get to it before that, great :)

lol I've already made a fork to add this feature (Guyutongxue/openai-rs) but, well, with using of once_cell::Lazy. Not a good practice for a Rust project...

I agree, but it's still better than nothing. We should also eventually refactor out the global API key. Although I think it's unlikely a project would hit 2 different APIs, but still we shouldn't assume.
