//CompletionResponse completions = //openAiClient.completions("我想申请转专业，从计算机专业转到会计学专业，帮我完成一份两百字左右的申请书");
//最新GPT-3.5-Turbo模型
Message message = Message.builder().role(Message.Role.USER).content("你好啊我的伙伴！").build();
ChatCompletion chatCompletion = ChatCompletion.builder().messages(Arrays.asList(message)).build();
ChatCompletionResponse chatCompletionResponse = openAiClient.chatCompletion(chatCompletion);
chatCompletionResponse.getChoices().forEach(e -> {
System.out.println(e.getMessage());
});
}
}
支持流式输出
官方对于解决请求缓慢的情况推荐使用流式输出模式。
主要是基于SSE 实现的（可以百度下这个技术）。也是最近在了解到SSE。OpenAI官网在接受Completions接口的时候，有提到过这个技术。 Completion对象本身有一个stream属性，当stream为true时候Api的Response返回就会变成Http长链接。 具体可以看下文档：https://platform.openai.com/docs/api-reference/completions/create

client.streamChatCompletion(chatCompletion, eventSourceListener);
CountDownLatch countDownLatch = new CountDownLatch(1);
try {
countDownLatch.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
//常规对话模型
@Test
public void completions() {
ConsoleEventSourceListener eventSourceListener = new ConsoleEventSourceListener();
Completion q = Completion.builder()
.prompt("我想申请转专业，从计算机专业转到会计学专业，帮我完成一份两百字左右的申请书")
.stream(true)
.build();
client.streamCompletions(q, eventSourceListener);
CountDownLatch countDownLatch = new CountDownLatch(1);
try {
countDownLatch.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

流式输出如何集成Spring Boot实现 api接口?
可以参考项目：https://github.com/Grt1228/chatgpt-steam-output
实现自定义的EventSourceListener，例如：OpenAIEventSourceListener并持有一个SseEmitter，通过SseEmitter进行数据的通信
postman测试
发送请求：Get http://localhost:8080/test/sse?uid=123
看下response （需要新版本postman）
重点关注下header：Content-Type：text/event-stream
如果想结合前端显示自行百度sse前端相关实现
说明
支持最新版的语音转文字，语音翻译api请参考测试代码：OpenAiClientTest.java
