Android studio前沿开发--利用socket服务器连接AI实现前后端交互（全站首发思路）

news 来源：原创 2025/5/21 9:25:27

我们在前几期学习了利用socket进行前后端的交互，但那只是基础性知识，这次，通过参考讯飞星火的java参考文档，再结合之前所学的socket服务，成功实现了通过后端将AI的调用实现在了自己的APP中。

本次的学习内容

1.真机的调用

2.讯飞星火账号appid的申请与调用

3.前后端的交互

4.服务器与AI的结合

1.真机的调用

打开真机的开发者模式，并用USB线将电脑与手机连接起来，并在手机的选中文件传输，让你的手机打开流量并开启热点，并保证你的电脑连接到这个热点，接下来，打开你电脑的命令提示窗口，输入以下命令：

获得IPv4地址，这个地址就是你的手机ip地址，记录下来后面要用到，这样你的手机已经可以连接到你的电脑后端了。

2.申请讯飞星火的账号

这个没什么好说的在讯飞星火的开发平台中申请一个账号，

并将这三个key记录下来，这是连接AI的必要条件，之后下载讯飞星火的Java示例代码，之后我们的服务器要在它的示例代码上进行修改：

当然，讯飞星火的AI也可以直接在app前端中进行调用，但目前版本适配性过低，而且限定的Java与SDK的版本，对版本不统一的使用者来说十分不友好，所以我还是建议通过后端去调用AI，避免前端线程的混乱。

3.前后端的交互

这里的代码与Android studio进阶开发（三）–socket通信服务的使用的代码几乎是一致的，只是把其中的IP地址转换为真机的地址
这里直接放代码：
Android：
1.创建dateuitl，获取当前时间

package com.example.newsoket;import android.annotation.SuppressLint;import java.text.SimpleDateFormat;
import java.util.Date;@SuppressLint("SimpleDateFormat")
public class DateUtil {// 获取当前的日期时间public static String getNowDateTime() {SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");return sdf.format(new Date());}// 获取当前的时间public static String getNowTime() {SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");return sdf.format(new Date());}// 获取当前的分钟public static String getNowMinute() {SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");return sdf.format(new Date());}// 获取当前的时间（精确到毫秒）public static String getNowTimeDetail() {SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss.SSS");return sdf.format(new Date());}// 将长整型的时间数值格式化为日期时间字符串public static String formatDate(long time) {Date date = new Date(time);SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");return sdf.format(date);}}

2.创建NetConst ,初始化端口和IP地址

package com.example.newsoket;public class NetConst {// HTTP地址的前缀public final static String HTTP_PREFIX = "http://192.168.1.7:8080/HttpServer/";// WebSocket服务的前缀public final static String WEBSOCKET_PREFIX = "ws://192.168.1.7:8080/HttpServer/";//public final static String BASE_IP = "192.168.1.7"; // 基础Socket服务的ippublic final static String BASE_IP = "192.168.43.9"; // 基础Socket服务的ip（这里要改为前面获取的IPv4的地址）public final static int BASE_PORT = 9010; // 基础Socket服务的端口public final static String CHAT_IP = "192.168.1.7"; // 聊天Socket服务的ippublic final static int CHAT_PORT = 9011; // 聊天Socket服务的端口
}

请添加图片描述

这里一定要改，否则连接不上后端服务器

3.创建SocketUtil 与socket连接进行判断

package com.example.newsoket;import android.app.Activity;
import android.widget.Toast;import com.google.gson.Gson;import org.json.JSONObject;import java.net.InetSocketAddress;
import java.net.SocketAddress;import io.socket.client.Socket;public class SocketUtil {// 把对象数据转换为json串，然后发给Socket服务器public static void emit(Socket socket, String event, Object obj) {try {JSONObject json = new JSONObject(new Gson().toJson(obj));socket.emit(event, json);} catch (Exception e) {e.printStackTrace();}}// 判断Socket能否连通public static void checkSocketAvailable(Activity act, String host, int port) {new Thread(() -> {try (java.net.Socket socket = new java.net.Socket()) {SocketAddress address = new InetSocketAddress(host, port);socket.connect(address, 1500);} catch (Exception e) {e.printStackTrace();act.runOnUiThread(() -> {Toast.makeText(act, "无法连接Socket服务器", Toast.LENGTH_SHORT).show();});}}).start();}}

4.创建sockettake.activity进行交互
xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:padding="5dp" ><EditTextandroid:id="@+id/et_input"android:layout_width="match_parent"android:layout_height="40dp"android:background="@drawable/editext_selector"<!可有可无，可以改为自己想要的>android:hint="请输入聊天内容"android:textColor="@color/black"android:textSize="17sp" /><Buttonandroid:id="@+id/btn_send"android:layout_width="match_parent"android:layout_height="wrap_content"android:text="发送文本消息"android:textColor="@color/black"android:textSize="17sp" /><TextViewandroid:id="@+id/tv_response"android:layout_width="match_parent"android:layout_height="wrap_content"android:textColor="@color/black"android:textSize="17sp" />
</LinearLayout>

java:

package com.example.newsoket;import android.os.Bundle;import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.graphics.Insets;
import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;
import android.os.Bundle;
import android.text.TextUtils;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;import androidx.appcompat.app.AppCompatActivity;import com.example.newsoket.NetConst;
import com.example.newsoket.DateUtil;
import com.example.newsoket.SocketUtil;import java.net.URISyntaxException;import io.socket.client.IO;
import io.socket.client.Socket;import java.net.URISyntaxException;public class Sockettext extends AppCompatActivity {private static final String TAG = "SocketioTextActivity";private EditText et_input; // 声明一个编辑框对象private TextView tv_response; // 声明一个文本视图对象private Socket mSocket; // 声明一个套接字对象@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_sockettext);et_input = findViewById(R.id.et_input);tv_response = findViewById(R.id.tv_response);findViewById(R.id.btn_send).setOnClickListener(v -> {String content = et_input.getText().toString();if (TextUtils.isEmpty(content)) {Toast.makeText(this, "请输入聊天消息", Toast.LENGTH_SHORT).show();return;}mSocket.emit("send_text", content); // 往Socket服务器发送文本消息});initSocket(); // 初始化套接字}// 初始化套接字private void initSocket() {// 检查能否连上Socket服务器SocketUtil.checkSocketAvailable(this, NetConst.BASE_IP, NetConst.BASE_PORT);try {String uri = String.format("http://%s:%d/", NetConst.BASE_IP, NetConst.BASE_PORT);mSocket = IO.socket(uri); // 创建指定地址和端口的套接字实例} catch (URISyntaxException e) {throw new RuntimeException(e);}mSocket.connect(); // 建立Socket连接// 等待接收传来的文本消息mSocket.on("receive_text", (args) -> {String desc = String.format("%s 收到服务端消息：%s",DateUtil.getNowTime(), (String) args[0]);runOnUiThread(() -> tv_response.setText(desc));});}@Overrideprotected void onDestroy() {super.onDestroy();mSocket.off("receive_text"); // 取消接收传来的文本消息if (mSocket.connected()) { // 已经连上Socket服务器mSocket.disconnect(); // 断开Socket连接}mSocket.close(); // 关闭Socket连接}
}

后端idea的代码：

package com.socketio.server;import com.alibaba.fastjson.JSONObject;
import com.corundumstudio.socketio.AckRequest;
import com.corundumstudio.socketio.Configuration;
import com.corundumstudio.socketio.SocketIOClient;
import com.corundumstudio.socketio.SocketIOServer;
import com.corundumstudio.socketio.listener.ConnectListener;
import com.corundumstudio.socketio.listener.DataListener;
import com.corundumstudio.socketio.listener.DisconnectListener;public class SocketServer {public static void main(String[] args) {Configuration config = new Configuration();// 如果调用了setHostname方法，就只能通过主机名访问，不能通过IP访问//config.setHostname("localhost");config.setPort(9010); // 设置监听端口final SocketIOServer server = new SocketIOServer(config);// 添加连接连通的监听事件server.addConnectListener(client -> {System.out.println(client.getSessionId().toString()+"已连接");});// 添加连接断开的监听事件server.addDisconnectListener(client -> {System.out.println(client.getSessionId().toString()+"已断开");});// 添加文本发送的事件监听器server.addEventListener("send_text", String.class, (client, message, ackSender) -> {System.out.println(client.getSessionId().toString()+"发送文本消息："+message);client.sendEvent("receive_text", "我已收到，马上做出回应。");});// 添加图像发送的事件监听器server.addEventListener("send_image", JSONObject.class, (client, json, ackSender) -> {String desc = String.format("%s，序号为%d", json.getString("name"), json.getIntValue("seq"));System.out.println(client.getSessionId().toString()+"发送图片消息："+desc);client.sendEvent("receive_image", json);});server.start(); // 启动Socket服务}}

我们先来看下之前没有放出的示例图：
一定要先运行服务端的代码，再打开APP调试

这样前后端就有了响应。

4.服务器与AI的结合

还记得我们的标题吗，没错是我们与AI的互动，也就说，我们在对话框中输出文字并发送之后，给予我们回复的不在是固定的文字，而是AI根据我们的问题进行回复，实现基本的人机交互。
（1）解压在讯飞星火下载的压缩包

用idea打开文件夹下的讯飞大模型请添加图片描述
将这部分填好，试着运行一下：
请添加图片描述
在下方中的“我”后面输入问题，看看是否有“大模型”进行回复

我们先来看一下两段代码

import com.corundumstudio.socketio.listener.ConnectListener;
import com.corundumstudio.socketio.listener.DataListener;
import com.corundumstudio.socketio.listener.DisconnectListener;public class SocketServer {public static void main(String[] args) {Configuration config = new Configuration();// 如果调用了setHostname方法，就只能通过主机名访问，不能通过IP访问//config.setHostname("localhost");config.setPort(9010); // 设置监听端口final SocketIOServer server = new SocketIOServer(config);// 添加连接连通的监听事件server.addConnectListener(client -> {System.out.println(client.getSessionId().toString()+"已连接");});// 添加连接断开的监听事件server.addDisconnectListener(client -> {System.out.println(client.getSessionId().toString()+"已断开");});// 添加文本发送的事件监听器server.addEventListener("send_text", String.class, (client, message, ackSender) -> {System.out.println(client.getSessionId().toString()+"发送文本消息："+message);client.sendEvent("receive_text", "我已收到，马上做出回应。");});// 添加图像发送的事件监听器server.addEventListener("send_image", JSONObject.class, (client, json, ackSender) -> {String desc = String.format("%s，序号为%d", json.getString("name"), json.getIntValue("seq"));System.out.println(client.getSessionId().toString()+"发送图片消息："+desc);client.sendEvent("receive_image", json);});server.start(); // 启动Socket服务}}

}

这是官方给我们的示例代码，但是只能将在下方运行框中进行使用，但是，如果你仔细看过我们的socket代码，我们其中的send_text和receive_text也是会在底下的输入框中进行输出的，所以我们可以将send_text替换为原AI代码中的“我”的部分，把receive_text的部分转换为“大模型“的部分并返回给页面，同时我们还要加上socket服务，在启动时，先要打开服务器，然后进行一系列操作

这是改正之后的，代码相当于两部分结合了一下，想要理解的同学不妨直接扔给AI解释一下（dogs):

这样看来，我们的ai+Socket服务器就连接成功了，并且能够进行实时对话，但可以看到，我们的页面只能显示最后输出的一句话，所以仍然需要进行修改，由于篇幅与时间问题，我这里就不再修改了，留给读者们自由发挥的空间，这篇文章是作者的呕心沥血之作，也填补了目前网站所没有的空白，所以可以的话，可以给作者点一个赞或关注鼓励一下作者，如果有问题的话也欢迎与作者进行交流与讨论。
