• Unity 通过jar包形式接入讯飞星火SDK

    最近工作上遇到了要接入gpt相关内容的需求，简单实现了一个安卓端接入讯飞星火的UnitySDK。
    或者也可以接入WebSocket接口的。本文只讲安卓实现
    我使用的Unity版本为2021.3.27f1c2
    Android版本为4.2.2

    1.下载SDK

    登陆讯飞开放平台下载如图所示SDK
    在这里插入图片描述

    2.新建安卓工程

    新建安卓工程，在工程下创建libs文件夹
    在这里插入图片描述
    下载的SDK解压后的aar文件至安卓工程的libs文件夹下
    打开工程的build.gradle
    复制以下代码
    在这里插入图片描述
    上面红框部分是引用aar，下面是打jar包的逻辑

    3.根据原来的demo工程修改代码

    package com.rayneo.sparklib;
import android.app.Activity;
import com.iflytek.sparkchain.core.LLM;
import com.iflytek.sparkchain.core.LLMCallbacks;
import com.iflytek.sparkchain.core.LLMConfig;
import com.iflytek.sparkchain.core.SparkChain;
import com.iflytek.sparkchain.core.SparkChainConfig;

public class SparkTool {

    private static final String TAG = "SparkLLM";
    private Activity _unityActivity;

    private String domain ="general";
    private String url = "wss://spark-api.xf-yun.com/v1.1/chat";

    public int initSDK(String appid,String apiKey,String apiSecret,int logLevel,String domain,String url) {
        // 初始化SDK，Appid等信息在清单中配置
        SparkChainConfig sparkChainConfig = SparkChainConfig.builder();
        sparkChainConfig.appID(appid)
                .apiKey(apiKey)
                .apiSecret(apiSecret)//应用申请的appid三元组
                .logLevel(logLevel);

        int ret = SparkChain.getInst().init(getActivity(),sparkChainConfig);

        this.domain = domain;
        this.url = url;

        return ret;
    }

    public void unInitSDK() {
        SparkChain.getInst().unInit();
    }

    Activity getActivity(){
        if(null == _unityActivity) {
            try {
                Class classtype = Class.forName("com.unity3d.player.UnityPlayer");
                Activity activity = (Activity) classtype.getDeclaredField("currentActivity").get(classtype);
                _unityActivity = activity;
            } catch (ClassNotFoundException e) {

            } catch (IllegalAccessException e) {

            } catch (NoSuchFieldException e) {

            }
        }
        return _unityActivity;
    }

    public int startChat(ISparkLLMProxy unityProxy,String msg) {

        LLMConfig llmConfig = LLMConfig.builder();
        llmConfig.domain(domain)
                .url(url);
        LLM llm = new LLM(llmConfig);
        LLMCallbacks llmCallbacks = new SparkLLMCallbacks(unityProxy);
        llm.registerLLMCallbacks(llmCallbacks);
        String myContext = "myContext";

        int ret = llm.arun(msg,myContext);

        return ret;
    }

}

    这几个接口分别是初始化，释放，获取Unity的Activity，开始gpt。

    package com.rayneo.sparklib;

public interface ISparkLLMProxy {

    void onLLMResult(int status, String Content);

    void onLLMEvent(int eventID, String eventMsg);

    void onLLMError(int errorCode, String var2);
