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

巴特西

OpenAI Java SDK——chatgpt-java-v1.0.3更新支持GPT-3.5-Turbo，支持语音转文字，语音翻译。
