看了下electron的代码

class IncomingMessage extends EventEmitter {

    // Docs: http://electron.atom.io/docs/api/incoming-message

    /**
     * Emitted when a request has been canceled during an ongoing HTTP transaction.
     */
    on(event: 'aborted', listener: Function): this;
    once(event: 'aborted', listener: Function): this;
    addListener(event: 'aborted', listener: Function): this;
    removeListener(event: 'aborted', listener: Function): this;
    /**
     * The data event is the usual method of transferring response data into
     * applicative code.

    on(event: 'data', listener: (
                                 /**

                                 chunk: Buffer) => void): this;
    once(event: 'data', listener: (
                                 /**

                                 chunk: Buffer) => void): this;
    addListener(event: 'data', listener: (

对于进入消息提供的API

目前程序是一个与telet交互的程序，输出的内容渲染到了web页，所以on('data')已经用了，而且不能被移除。

移除了页面就不输出连续的内容了，必须保持监听。

现在因为要做触发器，所以需要在另外一个类里监听'data'事件

用eventNames() 打印可以看到[ 'end', 'finish', '_socketEnd', 'data' ]

所以我的问题是，如何再增加一个对'data'的监听事件？

用过addListener，但是打印事件名还是[ 'end', 'finish', '_socketEnd', 'data' ]所以也没办法用removeListener移除。

求解
