将输出读取到文件 Node.js

如何将输出写入文件？我尝试代替process.stdout use fs.createWriteStream(temp + '/export2.json')，但它不起作用。

var rl = readline.createInterface({
    input: fs.createReadStream(temp + '/export.json'),
    output: process.stdout,
    terminal: false
});

rl.on('line', function(line) {
    rl.write(line);
});

readline不使用 with 写入文件output选项。但是，您可以照常创建写入流并照常写入。

Example:

const { EOL } = require("os");
const rl = readline.createInterface({
    input: fs.createReadStream(temp + '/export.json'),
});

const writeStream = fs.createWriteStream(temp + '/export2.json', { encoding: "utf8" })

rl.on('line', function(line) {
    writeStream.write(`${line}${EOL}`);
});
