快速开始

导入pom依赖

    com.unfbx    chatgpt-java    1.0.3
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;********************/** * @author https:www.unfbx.com * 2023-02-28 */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();        }    }}

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
