如何在同一读行中接受多个输入.问题和存储在不同的变量

Question

所以我想在同一个readline中请求来自用户的多个输入。问题，并想把它存储到不同的变量中，但我面临的问题是，我不知道怎么做。

import * as readline from 'node:readline';
function askQuestion(query) {
const io = readline.createInterface({
input: process.stdin,
output: process.stdout,
terminal: false
});
return new Promise(resolve => io.question(query, ans => {
resolve(ans);
}));
}
let numRows;
let numCols;
let winLength;
numRows = await askQuestion("Please enter the rows number ");
numCols = await askQuestion("Please enter the columns number ");
winLength = await askQuestion("Please enter the win length ");

numRows, numCols, winLength = await askQuestion(`Please enter${numRows}x${numCols} = ${winLength}`);

我想这样做，但这是不工作。

我面临的另一件事是，它问了很多问题后，我得到了内存泄漏错误在终端

(node:7220) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 end listeners added to [ReadStream]. Use emitter.setMaxListeners() to increase limit
(Use `node --trace-warnings ...` to show where the warning was created)

谁能解决这个内存泄漏错误?

Answer 1

为什么不关闭Readline?

io.close();
resolve(ans);
