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

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);}

package com.rayneo.sparklib;import android.util.Log;import com.iflytek.sparkchain.core.LLMCallbacks;
import com.iflytek.sparkchain.core.LLMError;
import com.iflytek.sparkchain.core.LLMEvent;
import com.iflytek.sparkchain.core.LLMResult;public class SparkLLMCallbacks implements LLMCallbacks {private static final String TAG = "SparkLLMCallbacks";private ISparkLLMProxy unityProxy;public SparkLLMCallbacks(ISparkLLMProxy unityProxy) {this.unityProxy = unityProxy;}@Overridepublic void onLLMResult(LLMResult llmResult, Object usrContext) {Log.d(TAG, "onLLMResult\n");String content = llmResult.getContent();Log.e(TAG, "onLLMResult:" + content);int status = llmResult.getStatus();if (unityProxy != null) {unityProxy.onLLMResult(status, content);}}@Overridepublic void onLLMEvent(LLMEvent event, Object usrContext) {Log.d(TAG, "onLLMEvent\n");Log.w(TAG, "onLLMEvent:" + " " + event.getEventID() + " " + event.getEventMsg());if (unityProxy != null) {unityProxy.onLLMEvent(event.getEventID(), event.getEventMsg());}}@Overridepublic void onLLMError(LLMError error, Object usrContext) {Log.d(TAG, "onLLMError\n");Log.e(TAG, "errCode:" + error.getErrCode() + "errDesc:" + error.getErrMsg());if (unityProxy != null) {unityProxy.onLLMError(error.getErrCode(), error.getErrMsg());}}
}

4.导入Unity工程

拷贝jar包和aar包至Unity工程此目录下
