Question

编程的新手，我正在制作一个Twitch聊天机器人，我想添加一个命令，使该机器人以文本文件中的随机行作为响应，而我正在努力寻找要使用的变量和/或模块

Answer 1

mydata.json

带有字符串数组的JSON文件。

[
  "This is a message",
  "Where are you?",
  "I'm calling from inside the house..."
]

main.js

const fs = require('fs');

// Read and parese the JSON file 
const messages = JSON.parse(fs.readFileSync('mydata.json','utf8'));

// get a random message
function getRandomMessage() {
  return messages[ Math.floor( Math.random() * messages.length ) ];
}


console.log(getRandomMessage());

关于第二个问题...

因此，您希望它与短语匹配吗？我可以做得更好。通过使用regular expression，同一封邮件可以匹配多个短语。我还允许同一短语匹配多个消息，并且它随机选择匹配的消息之一。

random_messages.js

const fs = require('fs');

function readMessages(filename) {
  // Read and parese the JSON file
  const messages = JSON.parse(fs.readFileSync(filename,"utf8"));
  // compile the regular expressions, case insensitive
  for (const message of messages) message.match = new RegExp( message.match, "i" );
  return messages;
}


// get a random message
function getRandomMessage(messges, phrase) {
  // Get a list of all matching messages
  const list = messages.filter( message => message.match.test( phrase ) );
  // Return null if there was no matching messages
  if (!list.length) return null;
  // Select a random message from the list of matching messages
  return list[ Math.floor( Math.random() * list.length ) ].text;
}

function test(messages) {
  console.log(getRandomMessage(messages, "Hello everyone!"));
  for (let i = 1; i <= 65536; i*=2) {
    const phrase = `I have ${i} bottles`;
    const response = getRandomMessage(messages, phrase);
    console.log( "User:", phrase);
    if (response) console.log("Bot", response);
  }
}

// Read all the messages ( you should do that one time at program startup. NOT for every chat message)
const messages = readMessages("random_messages.json");
test(messages);

random_messages.json

[
  {
    "text": "This is a message",
    "match": "^what is this\\?"
  },
  {
    "text": "Where are you?",
    "match" : "^hello\\b"
  },
  {
    "text": "Who are you?",
    "match" : "^hello\\b"
  },
  {
    "text": "Hello!!!!",
    "match" : "^hello\\b"
  },
  {
    "text": "Hello!!!! Nice to meet you!",
    "match" : "^hello\\b"
  },
  {
    "text": "Hello!!! There you are! I'm been waiting for you!",
    "match" : "^hello\\b"
  },
  {
    "text": "Wow! That is plenty of bottles!",
    "match" : "\\b(:?[1-9]\\d+|[5-9]) bottles\\b"
  }
]

如何使机器人从文本文件中说出随机行？
