问题 I have byte[] zipFileAsByteArray This zip file has rootDir --| | --- Folder1 - first.txt | --- Folder2 - second.txt | --- PictureFolder - image.png What I need is to get two txt files and read them, without saving any files on disk. Just do it in memory. I tried something like this: ByteArrayInputStream bis = new ByteArrayInputStream(processZip); ZipInputStream zis = new ZipInputStream(bis); Also I will need to have separate method go get picture. Something like this: public byte[]image

“ 来源：pypypypy www.cnblogs.com/pypypy/p/12011506.html 内置函数就是python给你提供的, 拿来直接用的函数，比如print.，input等。截止到python版本3.6.2 python一共提供了68个内置函数。 # 68个内置函数 # abs() 　　dict() 　　 help () 　　min() 　　setattr() # all() 　　dir() 　　hex() 　　next() 　　slice() # any() 　　divmod() 　　id() 　　object() 　　sorted() # ascii() 　　enumerate() 　　input() 　　oct() 　　staticmethod() # bin() 　　 eval () 　　int() 　　open() 　　str() # bool() 　　 exec () 　　isinstance() 　　ord() 　　sum() # bytearray() 　　filter() 　　issubclass() 　　pow() 　　super() # bytes() 　　float() 　　iter() 　　 print () 　　tuple() # callable() 　　format() 　　len() 　　property() 　　 type ()

How to reduce TrueVFS dependencies

由 ╄→尐↘猪︶ㄣ 提交于 2020-01-03 21:02:29
问题 I was recently looking for a decent library to work with ZIP files. Several post on SO recommended TrueVFS, formerly TrueZip. I need to extract individual files, modify them, and put them back to archive, overriding the old one. The goal is to write library to upload Java macros to ODF files, Libre Office/Open Office documents, which are in fact standard ZIP files. The TrueVFS documentation lacks basics, so it took me some time and experimentation to find that one can do it very easily:

TrueZip - How to decompress inner jar/zip files without expanding them as directories?

由 十年热恋 提交于 2019-12-13 12:11:25
问题 I'm creating a tzp file using TrueZip 7, and the cp_rp method to add all directory contents at once to the tzp file. After that, I'm trying to extract all contents of the tzp file to a target directory. However, the call: zipFile = new TFile("test.zip"); public void extract(TFile file){ for (TFile iFile : zipFile.listFiles()){ if(iFile.isDirectory()){ extract(iFile); }else{ File output = new File(iFile.getPath()); iFile.mv(output); } } } Fails with an error: java.io.IOException: [path]\test

append a file to zip using TrueZip

由 梦想的初衷 提交于 2019-12-12 17:44:48
问题 I want to use the TrueZip library to append a file to an existing archive (not by unpacking, adding a file and repacking - the new versions are supposed to have this feature), but I find it a bit difficult to understand the API. Can please someone, more knowledgeable than me, suggest how to do this in a few lines? 回答1: Google is your friend: Appending entries to ZIP files with TrueZIP 7.3 来源： https://stackoverflow.com/questions/9889629/append-a-file-to-zip-using-truezip
