Question

我使用cavariux库创建了自定义的Twitch机器人。我在主类中调用了此方法。

bot.setOauth_Key("oauth:key_Value");
bot.connect();
bot.joinChannel(channel.toString());
bot.start();

该机器人5-6次启动中的大约一种伴随着一个异常

java.net.SocketException：对等重置连接

。堆栈跟踪指示异常从这一行开始。

while ((line = this.reader.readLine( )) != null && !stopped)

在method start()的TwitchBot类中为

。除了在方法connect(String ip, int port)中添加utf编码外，我没有更改此库的代码。

this.writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), StandardCharsets.UTF_8));
this.reader = new BufferedReader(new InputStreamReader(socket.getInputStream(), StandardCharsets.UTF_8));

我已经在不同的PC上测试了我的机器人。在某些机器上，我没有这个问题。在某些情况下，我更经常遇到这种例外情况。这是TwitchBot类中方法start（）的代码。

 public final void start()
        {
            if (isRunning()) return;
            String line = "";
            stopped = false;

                while ((line = this.reader.readLine( )) != null && !stopped) {
                    if (line.toLowerCase( ).startsWith("ping")) {

                        this.writer.write("PONG " + line.substring(5) + "\r\n");
                        this.writer.flush();

这是TwitchBot类中方法connect（）的代码。

public void connect(String ip, int port)
    {

                System.exit(1);
                return;
            }
            if (oauth_key == null || oauth_key == "")
            {
                LOGGER.log(Level.SEVERE,"Please select a valid Oauth_Key");
                System.exit(2);
                return;
            }

            @SuppressWarnings("resource")
            Socket socket = new Socket(ip, port);
            this.writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), StandardCharsets.UTF_8));
            this.reader = new BufferedReader(new InputStreamReader(socket.getInputStream(),StandardCharsets.UTF_8));

            this.writer.write("PASS " + oauth_key + "\r\n");
            this.writer.write("NICK " + user + "\r\n");
            this.writer.write("USER " + this.getVersion() + " \r\n");
            this.writer.write("CAP REQ :twitch.tv/commands \r\n");
            this.writer.write("CAP REQ :twitch.tv/membership \r\n");
            this.writer.flush();

            String line = "";
            while ((line = this.reader.readLine()) != null)
            {
                 if (line.indexOf("004") >= 0) {
                        LOGGER.log(Level.INFO,"Connected >> " + user + " ~ irc.twitch.tv");
                        break;

                        LOGGER.log(Level.INFO,line);
                    }
            }
        } catch (IOException e)
        {
            e.printStackTrace();
        }
    }

此错误表示对等方（即Twitch服务器）突然关闭了您的连接。有关更多详细信息，请参见this answer。

我不知道您是否可以做些什么来解决此问题，因为它可能有多种外部原因（同行崩溃...）。也许您可以等待并稍后尝试重新连接（请注意，如果连接频率太高，您可能会被列入黑名单）。
