node.js打开浏览器

经过nodejs的child_process识别环境, 用不一样的CLI打开默认浏览器:

var child_process = require("child_process");

var url = "http://127.0.0.1",
      port=8080,
      cmd = '';

    switch (process.platform) {
        case 'wind32':
            cmd = 'start';
            break;

        case 'linux':
            cmd = 'xdg-open';
            break;

        case 'darwin':
            cmd = 'open';
            break;
    }

    child_process.exec(cmd + ' ' + url + ':' + port);
