快速开始

导入pom依赖

<dependency>
    <groupId>com.unfbx</groupId>
    <artifactId>chatgpt-java</artifactId>
    <version>1.0.3</version>
</dependency>

package com.unfbx.eventTest.test;
import com.unfbx.chatgpt.OpenAiClient;
import com.unfbx.chatgpt.entity.completions.CompletionResponse;
import java.util.Arrays;

public class TestB {
    public static void main(String[] args) {
        //代理可以为null
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("192.168.1.111", 7890));
        OpenAiClient openAiClient = OpenAiClient.builder()
                .apiKey("sk-**************")
                .proxy(proxy)
                .build();
        //简单模型
        //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

package com.unfbx.chatgpt;

public class OpenAiStreamClientTest {

    private OpenAiStreamClient client;
    @Before
    public void before() {
        //创建流式输出客户端
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("192.168.1.111", 7890));
        client = OpenAiStreamClient.builder()
                .connectTimeout(50)
                .readTimeout(50)
                .writeTimeout(50)
                .apiKey("sk-******************************")
                .proxy(proxy)
                .build();
    }
    //GPT-3.5-Turbo模型
    @Test
    public void chatCompletions() {
        ConsoleEventSourceListener eventSourceListener = new ConsoleEventSourceListener();
        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();
        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();
        }
    }

}

输出的是sse流式数据：

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
