问题 I have some files, from a Unity build, that I am unable to add headers to. They have extensions jsgz, memgz and datagz. They are located in my public folder within my NodeJs project. I am using Express 4 and have set up Compression but I believe that this only compresses existing files for transmission, and does not handle files that are already compressed. I have tried using app.get to add headers but it doesn't seem to work: app.get('/blah/unitymodels/Release/widget.js', function(req, res,

问题 I want to use zlib because I'm assuming it's the best & fastest way to gzip NSData . But, is there a better way? If not, which version of the zlib library should I link to in Xcode: libz.dylib, libz.1.dylib, libz.1.1.3.dylib, or libz.1.2.5.dylib? Please provide a code example of how to us zlib to convert NSData *normalHTTPBody into NSData gzippedHTTPBody 回答1: Yes, zlib is what is used to gzip data. I know of no better way. As for speed, you can select the compression level to optimize speed

问题 I m trying to gzip compress the img I m serving through CloudFront . My origin is S3 Based on several articles/blogs on aws, what I did is: 1) Set "Content-Length" header for the object I want to compress. I set the value equal to the size appeared on the size property box 2) Set the Compress Objects Automatically value to Yes in the Behaviour of my cloud distribution. 3) I invalidated my object to get a fresh copy from S3 . Still I m not able to make CloudFront gzip my object. Any ideas? 回答1

问题 How Can I read a data sent to a server directly into parts if the data was sent as a gzip? Here is the basic android code that uploads the file(s) to the server private void sendViaUrlConnection(String urlPost, ArrayList<BasicNameValuePair> pairList, File[] sentfileList) { HttpURLConnection connection = null; GZIPOutputStream gz = null; DataOutputStream outputStream = null; OutputStream serverOutputStream = null; try { URL url = new URL(urlPost); connection = (HttpURLConnection) url

问题 I know that okhttp3 library by default it adds the header Accept-Encoding: gzip and decodes the response automatically for us. The problem I'm dealing with a host that only accepts a header like: Accept-Encoding: gzip, deflate if I don't add the deflate part it fails. Now when I manually add that header to okhttp client, the library doesn't do the decompression anymore for me. I've tried multiple solutions to take the response and try to manually decompress that but I've always ended up with

问题 Using maven, I download some Chef cookbooks. Received files are in the .tgz format, and I want to unpack them. How can I do that ? Is there any useful plugin ? 回答1: From what I know, .tgz can be unpack via two commands: gzip -d file.tgz tar xvf file.tar So you can use maven-antrun-plugin to execute these two tasks: <gunzip src="tools.tgz"/> <untar src="tools.tar" dest="${tools.home}"/> Ant task reference: gunzip and untar 回答2: I would suggest to use the truezip-maven-plugin to handle such

问题 I need to efficently access a large gzipped xml file from javascript (actually from Greasemonkey). Unfortunately, the server doesn't provide a Content-Encoding header, and Content-Type is "application/x-gzip", so firefox will not (as far as I can tell) automatically inflate it. If there's a way to fake firefox out, that would be ideal. Short of that, I need some way to efficiently do the inflation...what I'm using now takes about 30 seconds to deflate the 1.2Mb gzipped file; I'd like to get
