如何使用Crypto ++解析ZIP文件？
[英]How can one parse a ZIP file using Crypto++?
问题描述
DEFLATE (RFC 1951) compression/decompression with gzip (RFC 1952) and zlib (RFC 1950) format support
使用gzip（RFC 1952）和zlib（RFC 1950）格式支持DEFLATE（RFC 1951）压缩/解压缩
, but I'm not sure how I could translate that into reading a ZIP file. ，但我不确定如何将其翻译成读取ZIP文件。 (I'm not averse to implementing my own ZIP traversing logic; but of course if the library already has that built in I don't want to duplicate things). （我不反对实现我自己的ZIP遍历逻辑;但当然如果库已经内置了我不想复制的东西）。
If the library doesn't provide this functionality out of the box, how does one access the zlib and gzip bits (in order to implement the compression/decompression steps)? 如果库没有提供开箱即用的功能，那么如何访问zlib和gzip位（为了实现压缩/解压缩步骤）？

I am not sure about the latest versions of Crypto++ but it was something like this before 我不确定最新版本的Crypto ++，但它之前就是这样的
// write to file
Gzip zip(new FileSink (output_filename, true ), Gzip::DEFAULT_DEFLATE_LEVEL);
zip.Put(buf, dwBufSize);
zip.MessageEnd();
