Question

我想为firefox开发一个插件，将进度事件发送到套接字服务器，以下代码属于我在插件中的javascript：

onProgressChange: function( aWebProgress, aRequest, aCurSelfProgress, aMaxSelfProgress, aCurTotalProgress, aMaxTotalProgress, aDownload){
    // alert("1: "+aWebProgress+" 2: "+aRequest+" 3: "+aCurSelfProgress+" 4: "+aMaxSelfProgress+" 5: "+aCurTotalProgress+" 6: "+aMaxTotalProgress+" 7: "+aDownload);

    var transport = Components.classes["@mozilla.org/network/socket-transport-service;1"]
                          .getService(Components.interfaces.nsISocketTransportService)
                          .createTransport(null, 0, "127.0.0.1", 23456, null);
    var stream = transport.openOutputStream(0, 0, 0);
    var data = "ProgressChange;"+String(aCurSelfProgress)+";"+String(aMaxSelfProgress)+";"+String(aCurTotalProgress)+";"+String(aMaxTotalProgress)+";"+String(aDownload.id)+";"+String(aDownload.state)+";"+String(aDownload.displayName);
    stream.write(data, data.length);
    stream.close();
  }

存在以下问题：

aCurSelfProgress和aCurTotalProgress始终具有相同的值，它与正在运行的下载量无关。

在我看来，aCurTotalProgress必须是每次下载的每个aCurTotalProgress的总和，但事实并非如此。无法识别多个下载...

我是否误解了参考文献： nsIDownloadProgressListener

有任何帮助或提示吗？

Mozilla nsIDownloadProgressListener不处理多次下载
