gzip

问题 I have a web-service running on Windows Azure which returns JSON that I consume in my iPhone app. Unfortunately, Windows Azure doesn't seem to support the compression of dynamic responses yet (long story) so I decided to get around it by returning an uncompressed JSON package, which contains a compressed (using GZIP) string. e.g {"Error":null,"IsCompressed":true,"Success":true,"Value":"vWsAAB+LCAAAAAAAB..etc.."} ... where value is the compressed string of a complex object represented in JSON.

问题 I need to send a POST request to a web server which includes a gzipped request parameter. I'm using Apache HttpClient and I've read that it supports Gzip out of the box, but I can't find any examples of how to do what I need. I'd appreciate it if anyone could post some examples of this. 回答1: You need to turn that String into a gzipped byte[] or (temp) File first. Let's assume that it's not an extraordinary large String value so that a byte[] is safe enough for the available JVM memory: String

问题 Someone knows a java library to decode/encode SDCH compression??? it has been created by Google and implemented in their Google Chrome web browser... so it will be a standard soon Some links about it: http://en.wikipedia.org/wiki/Shared_Dictionary_Compression_Over_HTTP http://google-opensource.blogspot.ie/2008/09/open-vcdiff-encoder-and-decoder-for-rfc.html Thanks! 回答1: SDCH is the name of the standard which applies the VCDIFF compression algorithm to HTTP. The web page lists implementations.

问题 I've been trying all day to make this thing works but it's still not right yet. I've checked so many posts around here and tested so many different implementations that I'dont know where to look now... Here is my situation, I have a small php test file (gz.php) on my server wich looks like this : header("Content-Encoding: gzip"); print("\x1f\x8b\x08\x00\x00\x00\x00\x00"); $contents = gzcompress("Is it working?", 9); print($contents); This is the simplest I could do and it works fine with any

问题 Given a string, how can I compress it in memory with gzip? I'm using Lua. It sounds like an easy problem, but there is a huge list of libraries. So far, all that I tried were either dead or I could produce only zlib compressed strings. In my use case, I need gzip compression, as it is expected by the receiver. As a test, if you dump the compressed string to a file, zcat should be able to decompress it. I'm using OpenResty, so any Lua library should be fine. (The only solution that I got

问题 I have a problem with the inclusion of compression on my website. Site hosted with WordPress and GZIP compression of HTML works fine even without any lines in the .htaccess or plug-ins. But the compression of JS/CSS does not turn on. Ive tried a lot of different codes, such as: <IfModule mod_deflate.c> <FilesMatch "\.(html|php|txt|xml|js|css)$"> SetOutputFilter DEFLATE </FilesMatch> </IfModule> or AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html

问题 By stating Features: no 4GB limit ... Idzip just uses multiple gzip members to have no file size limit. the author of idzip seems to imply that multiple gzip members are necessary to support data > 4GB. But the deflate algorithm, whose output gzip members merely wrap with header and footer, evidently supports more than 4GB of input. So is it really necessary to use multiple gzip members to compress more than 4GB of data? 回答1: Even .net's GZipStream , which does not support multiple members

问题 I have an Express.js app that uses connect-asssets to serve JS and CSS: app.configure(function() { app.set('port', 3000); app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs'); app.use(connectAssets({src: path.join(__dirname, 'assets')})); }); I'm trying to use Zombie.js for acceptance testing, but keep getting SyntaxError: Unexpected token ILLEGAL whenever it tries to parse a Javascript file. If I replace connect-assets with express.static , then the acceptance tests
