实现

2.1调用

        ArrayList<ChatGPTUPBodyBean.MessageBean> list = new ArrayList<>();
        list.add(new ChatGPTUPBodyBean.MessageBean("user","Who are you?"));
        ChatGPTUPBodyBean bodyBean = new ChatGPTUPBodyBean(list,"gpt-3.5-turbo") ;
        Map<String, String> headerMap = new HashMap<>();
        headerMap.put("Content-Type", "application/json");
        headerMap.put("Authorization", "Bearer 你的API Keys");
        ChatGPTRetrofitManager.getInstance().create(IChatGPTService.class).completions(bodyBean,headerMap)
                .subscribeOn(Schedulers.io())//切换到IO线程
                .observeOn(AndroidSchedulers.mainThread())//切换到主线程
                // 添加订阅
                .subscribe(responseData -> {
                }, throwable -> {
                    ToastUtil.showMessage(R.string.str_network_exception);
                });

2.2 IChatGPTService

1.以Body的形式传递数据
2.设置请求头

public interface IChatGPTService {
    @POST("v1/chat/completions")
    Observable<ChatGPTBean> completions(@Body ChatGPTUPBodyBean bodyBean, @HeaderMap Map<String,String> headerMap);
}

2.3 上行参数(ChatGPTUPBodyBean)

public class ChatGPTUPBodyBean {

    public List<MessageBean> messages;
    public String model;

    public static class MessageBean {
        /**
         * role : user
         * content : Who are you?
         */

        public String role;
        public String content;

        public MessageBean(String role, String content) {
            this.role = role;
            this.content = content;
        }
    }

    public ChatGPTUPBodyBean(List<MessageBean> messages, String model) {
        this.messages = messages;
        this.model = model;
    }
}
