ZipFile.readCentralDir介绍

[英]Find the central directory and read the contents.

The central directory can be followed by a variable-length comment field, so we have to scan through it backwards. The comment is at most 64K, plus we have 18 bytes for the end-of-central-dir stuff itself, plus apparently sometimes people throw random junk on the end just for the fun of it.

This is all a little wobbly. If the wrong value ends up in the EOCD area, we're hosed. This appears to be the way that everybody handles it though, so we're in good company if this fails.
[中]找到中心目录并阅读内容。
中央目录后面可以跟一个可变长度的注释字段，所以我们必须向后扫描它。评论最多64K，加上我们有18个字节作为central dir内容本身的结尾，而且显然有时候人们只是为了好玩而在结尾随意扔垃圾。
这一切都有点不稳定。如果EOCD区域出现错误的值，我们将被冲洗。不过，这似乎是每个人处理问题的方式，所以如果失败了，我们会有很好的伙伴关系。
