    nsITraceableChannel

    这个接口用于允许拦截 HTTP 流量。It is implemented by nsIHttpChannel.
    1.0
    28
    Introduced
    Gecko 1.9.0.4
    继承于: nsISupports 最后修改于Gecko 1.9.0.4

    使用这个接口的典型方式如下:

    之后,你的 nsIStreamListener 实现将会获取到响应数据(response data),并且能够传递数据到原始的 nsIStreamListener(可能会修改它)。

    See nsITraceableChannel, Intercept HTTP Traffic for a more detailed description with code samples.

    See Modify URL before loading page in firefox for an overview of how to modify a request before it is made.

    Method overview

    nsIStreamListener setNewListener(in nsIStreamListener aListener);

    Methods

    setNewListener()

    用一个新的来替换该通道的当前监听器,返回先前分配给该通道的监听器。

    nsIStreamListener setNewListener(
      in nsIStreamListener aListener
    );
    
    参数
    aListener
    An nsIStreamListener to be notified of events on the HTTP channel.
    返回值

    该通道的前一个监听器。Each listener call through to the previous listener for every call, in order to establish a call chain to allow all interested parties a chance to act on each event.

    实现 nsIStreamListener

    一个 nsIStreamListener 接口传递给 setNewListener() 需要实现下列的方法,这是通过调用(这些方法)来通知它在 HTTP stream 上发生的事件:

    • onStartRequest:一个 HTTP 请求开始。
    • onDataAvailable:数据到达 HTTP 通道(HTTP channel)。
    • onStopRequest:HTTP 请求结束。
    Note: It is critical that you pass along requests to the previous listener as soon as possible -- especially for onStartRequest.

    Channels may restrict when you may replace the listener. In particular, listeners typically should not be replaced after onStartRequest has been called.
