Node.js multiline input

问题:

I'd like to prompt the user for input, let the user enter multiple lines of text, hitting enter between each line, then terminate the input by pressing CTRL+D or some such thing.

With "keypress", I can catch the EOF, but I would have to handle all the echoing, backspace handling, terminal escape sequences, etc. manually. It would be much better if I could use "readline", but somehow intercept the CTRL+D (EOF) with "keypress", but I'm not sure how I would go about that.

回答1:

You can use the line and close events:

var readline = require('readline');

var input = [];

var rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

rl.prompt();

rl.on('line', function (cmd) {

    input.push(cmd);
});

rl.on('close', function (cmd) {

    console.log(input.join('\n'));
    process.exit(0);
});
