Question

您好我正在为Twich工作一个Irc Bot，我想添加一个从txt文件获取文本并在命令中使用它的命令

EX：用户类型＆＃34;！song＆＃34;在聊天中 - ＆gt;机器人从txt文件中获取歌曲标题，并在聊天歌曲标题中说出来。

我得到了从txt文件中获取数据的部分，但我无法在命令中获取该数据。

import org.jibble.pircbot.*;
import java.io.BufferedReader;
import java.io.FileReader;

public class MprovBot extends PircBot 
{

// Get song title from Txt file
public static void main(String[] args) throws Exception {
    FileReader file = new FileReader ("song.txt");
    BufferedReader reader = new BufferedReader(file);

    String song = "";
    String line = reader.readLine();
    while (line != null){
        song += line;
        line = reader.readLine();
    } 

    System.out.println(song);
}

// IRC Commands_
public MprovBot() {
    this.setName("MprovBot");
}

public void onMessage(String channel, String sender,
    String login, String hostname, String message) {
    if (message.equalsIgnoreCase("!test")) {
        sendMessage (channel, "Test Done");
    }

    if (message.equalsIgnoreCase("!Command")) {
        sendMessage (channel, "This are the commands you can do.");
    }

    if (message.equalsIgnoreCase("!song")){
        sendMessage (channel, song);
    }
    }
    }

当我尝试编译代码时，我得到了这个

MprovBot.java:40: error: cannot find symbol
   sendMessage (channel, song);
                         ^
symbol:   variable song
location: class MprovBot

Answer 1

song方法中未定义变量onMessage()。所以编译器找不到变量。您需要做的是将main方法更改为具有返回类型的普通方法，并在接收!song命令时调用此方法。

public class MprovBot extends PircBot {

    // Get song title from Txt file AND return it!
    public String getSong() throws Exception {
        FileReader file = new FileReader ("song.txt");
        BufferedReader reader = new BufferedReader(file);

        String song = "";
        String line = reader.readLine();
        while (line != null){
            song += line;
            line = reader.readLine();
        } 

        return song;
    }

    // IRC Commands_
    public MprovBot() {
        this.setName("MprovBot");
    }

    public void onMessage(String channel, String sender,
        String login, String hostname, String message) {
        if (message.equalsIgnoreCase("!test")) {
            sendMessage (channel, "Test Done");
        }

        if (message.equalsIgnoreCase("!Command")) {
            sendMessage (channel, "This are the commands you can do.");
        }

        if (message.equalsIgnoreCase("!song")){
            String song = "";
            try {
                song = getSong();
            } catch(Exception e) { e.printStackTrace(); }
            sendMessage (channel, song);
        }
    }
}

Pircbot将txt文件中的gettin文本转换为命令
