zipEntry.rawContent
条目的原始内容（如果适用，还压缩着）在内存中保存时的样子，或者当没有可暴露的内存缓冲区时为 null —— 对于用 zlib.ZipEntry.createStream() 创建的条目，或者由 zipFile.get() 返回的基于文件的条目，其字节按需从磁盘读取而不是保留在内存中。要读取基于文件的条目，请使用 zipEntry.content() 或 zipEntry.contentIterator()。
🌐 The entry's raw (still compressed, if applicable) content when it is held in
memory, or null when there is no in-memory buffer to expose - for an entry
created with zlib.ZipEntry.createStream(), or a file-backed entry
returned by zipFile.get(), whose bytes are read from disk on demand
rather than retained. Use zipEntry.content() or
zipEntry.contentIterator() to read a file-backed entry.
