I am doing some development on the firefox both with javascript and C++ for some XPCOM components.
I am trying to monitor the http activity with nsIHttpActivityDistributor.
现在的问题是,是否存在属于<条码>的id的任何<代码>?
我想节省一些<代码>nsIHttpChannel提到C++中的物体,然后在Javascript或C++中处理。 事情是,目前我找不到一个elegent的路标,用以确定一个能够用于js和C++的频道物体,用于将其明确输入一个记录文档。
任何想法?
You can easily add your own data to HTTP channels, they always implement nsIPropertyBag2 and nsIWritablePropertyBag2 interfaces. Something along these lines (untested code, merely to illustrate the principle):
static PRInt64 maxChannelID = -1;
...
nsCOMPtr<nsIWritablePropertyBag2> bag = do_QueryInterface(channel);
if (!bag)
...
nsAutoString prop(NS_LITERAL_STRING("myChannelID"));
PRInt64 channelID;
rv = bag->GetPropertyAsInt64(prop, &channelID);
if (NS_FAILED(rv))
{
// First time that we see that channel, assign it an ID
channelID = ++maxChannelID;
rv = bag->SetPropertyAsInt64(prop, channelID)
if (NS_FAILED(rv))
...
}
printf("Channel ID: %i
", channelID);
不过,你可能要检查吉大港山区的情况。 我认为,在此情况下,管道财产被复制到新的渠道,并不确定这是你是否可取的。
