deflate

问题 How to decompress/decode gzip/deflate http/s responses in vba? Winhttp5.1 does not automatically decompress/decode gzipped or deflate responses. MSxml2 does decompress/decode responses, but does not allow custom headers or referers. 回答1: The following code can be used to decompress any compressed data, by calling the Inflate() Function from the Inflate module. Full inflate module code is given below. Of course you can change the module name and the function name but do it carefully.

问题 As the title says. How do you decompress a compressed string which was compressed with zlib deflate? What is the solid way of doing it with an explanation? 回答1: Try this - it is a minimal working example: package zlib.example; import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.util.Arrays; import java.util.zip.Deflater; import java.util.zip.DeflaterOutputStream; import java.util.zip.InflaterInputStream; /** * Created by keocra on 08.10.15. */ public class

问题 Is there any JS library that allows to provide input data in chunks rather than expecting 100% file content to be present in memory (string, Buffer, UInt8Array) before starting archivation? I checked several popular libraries like JSZip or archiver and found that they do not offer such functionality. We process large data tables, client side, using Javascript and we have feature to export table to CSV file, compress and upload to server. Currently we generate huge string which is passed to

问题 I have a byte stream that is a concatenation of sections, where each section is composed of a header plus a deflated byte stream. I need to split this byte stream sections but the header only contains information about the data in uncompressed form, no hint about the compressed data length so I can advance properly in the stream and parse the next section. So far the only way I found to advance past the deflated byte sequece is to parse it according to the this specification. From what I

问题 I'm trying to implement a deflate compressor and I have to decide whether to compress a block using the static huffman code or create a dynamic one. What is the rationale behind the length associated with the static code? (this is the table included in the rfc) Lit Value Bits --------- ---- 0 - 143 8 144 - 255 9 256 - 279 7 280 - 287 8 I thought static code was more biased towards plain ascii text, instead it looks like it prefers by a tiny bit the compression of the rle length What is a good

问题 I have a binary file with contents created by zlib.compress on Python, is there an easy way to open and decompress it in Clojure? import zlib import json with open('data.json.zlib', 'wb') as f: f.write(zlib.compress(json.dumps(data).encode('utf-8'))) Basicallly it isn't a gzip file, it is just bytes representing deflated data. I could only find these references but not quite what I'm looking for (I think first two are most relevant): deflateclj_hatemogi_clojure/deflate.clj funcool/buddy-core

问题 Assume that the gzip file and zip archive both use DEFLATE. Since both would store the same raw compressed data for the specific file, is it possible to add a pre-compressed .gz file to an existing .zip archive? Some metadata would likely be lost (or not available), but I am more concerned with the raw file data. 回答1: Yes. I don't remember why I wrote this, but I'm sure there was a very good reason. Make sure you read the caveats in the comments. /* gz2zip.c version 1.0, 31 July 2018
