gzip

问题 I'm trying to load a json file using angular (v1.2.6): $http.get('myfile.json').success(function(data) { ... } This works fine, except when I create a (static) compressed version of the file on the server, and try to load 'myfile.json.gz' instead (to reduce the loading time). The request headers seem correct (Chrome 31.0 on Mac) (as stated here and here): Accept: application/json, text/plain, */* Accept-Encoding: gzip,deflate,sdch while the response headers contain: Connection: close Accept

问题 When working with the gzip library in Python, very often I'd come across code that use the .read() function in a pattern that look like this: with gzip.open(filename) as bytestream: bytestream.read(16) buf = bytestream.read( IMAGE_SIZE * IMAGE_SIZE * num_images * NUM_CHANNELS ) data = np.frombuffer(buf, dtype=np.uint8).astype(np.float32) While I'm familiar with the context manager pattern, I struggle to really grasp what is it that the first line of code within the with context manager is

问题 I am trying to programmatically decompress a .xml.gz file. It seems to be all pretty straightforward as there are many examples available on the internet which tell you how to decompress a .gz file. However, every-time I try to do it, I get an exception: java.io.IOException: unknown format (magic number d4d4). I'm trying to do this in an Android app, is it supposed to be done differently from the way its done otherwise in Java? I'm following this example code available here. Anyone have any

问题 I'm trying to record my interactions with a SAAS website using JMeter 2.12. I get the following error trace as soon as I try to login: java.util.zip.ZipException: Not in GZIP format at java.util.zip.GZIPInputStream.readHeader(Unknown Source) at java.util.zip.GZIPInputStream.(Unknown Source) at java.util.zip.GZIPInputStream.(Unknown Source) at org.apache.http.client.entity.GzipDecompressingEntity.decorate(GzipDecompressingEntity.java:56) at org.apache.http.client.entity.DecompressingEntity

问题 This is a tricky one as I can't provide a reproducible example, but I'm hoping that others may have had experience dealing with this. Essentially I have a function that pulls a large quantity of data from a DB, cleans and reduces the size and loops through some parameters to produce a series of lm model objects, parameter values and other reference values. This is compiled into a complex list structure that totals about 10mb. It's then supposed to saved as an RDS file on AWS s3 where it's

问题 I currently have the following: use Rack::Rewrite use Rack::Cache, {:verbose=>true, :metastore=>"memcached://localhost:11211/rack-cache/meta", :entitystore=>"memcached://localhost:11211/rack-cache/body"} use Rack::Rewrite use Rack::Lock use Rack::Deflater use ActionController::Failsafe use #<Class:0x007fb34be9ac90> use ActionController::Session::DalliStore, #<Proc:0x007fb34bea3638@(eval):8 (lambda)> use Rails::Rack::Metal use ActionController::ParamsParser use Rack::MethodOverride use Rack:

问题 I want to zip my string values. These string values should be same as .net zipped strings. I wrote Decompress method and when I send a .net zipped string to it, it works correctly. But the Compress method does not work correctly. public static String Decompress(String zipText) throws IOException { int size = 0; byte[] gzipBuff = Base64.decode(zipText); ByteArrayInputStream memstream = new ByteArrayInputStream(gzipBuff, 4, gzipBuff.length - 4); GZIPInputStream gzin = new GZIPInputStream

问题 I use following .htaccess to set gzip compression: AddOutputFilterByType DEFLATE text/html image/png image/jpeg text/css text/javascript Please check this url: http://www.coinex.com/cn/silver_panda/proof/china_1984_27_gram_silver_panda_coin/ the gzip compression works for html, css, js and jpg, but not working for png (really amazing..) 回答1: PNG is already a compressed data format. Compressing it with GZIP is not likely to decrease the size, and can in fact make it larger. I'm surprised you

问题 I tried to send the text in gzip, but I don't know how. In the examples the code uses fs, but I don't want to send a text file, just a string. const zlib = require('zlib'); const http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html', 'Content-Encoding': 'gzip'}); const text = "Hello World!"; res.end(text); }).listen(80); 回答1: You're half way there. I can heartily agree that the documentation isn't quite up to snuff on how to do this;
