rss 不输出树洞、水区和垃圾场内容

直接在 ArticleFeedList 里处理会更好。可以看下提交记录

https://github.com/Terminus2049/2049bbs/commits/master

我会把issue完善下，免得你做重复工作

@翻车了 #1 我发不了帖子了！！！

我觉得，feed那段代码，实在不敢恭维！

feed下，走的是 ArticleFeedList

feed节点下，走的是 ArticleFeedCategoryList

我也想在ArticleFeedList里写，但是我觉得很多代码完全是重复而且冗余的

如果我来改，我是从route层就已经改掉了，后面的代码会精简很多

@张怀义 #5 我也发现这个问题了，打开控制台，是能看到反馈的，一般是标题过长等原因，但是不知道为啥没有弹出来。这个是js的问题，i hate js。

@张怀义 #2 你为啥发不了帖子？

的确很冗余，当时只是为了快速解决问题嘛，在原有全部帖子输出的基础上再搞一个。但现在木已成舟，说啥都晚了。

@小二 #3 不知道，点了“发表”，什么反应都没有。。

算了，有空把那些代码都改了吧。我是手机，没法git clone完整的项目，所以我都是怎么改简单，怎么来的

树洞、水区和垃圾场at无效
