gzip

问题 I have a need to test if a program that I'm writing is parsing the gzip header correctly, and that includes reading the FEXTRA, FNAME, and FCOMMENT fields. Yet it seems that gzip doesn't support creating archives with the FEXTRA and FCOMMENT fields -- only FNAME. Are there any existing tools which can do all three of these? 回答1: The Perl module IO::Compress::Gzip optionally lets you set the three fields you are intrested in. ( Fair disclosure : I am the author of the module) Here is some

问题 I have the following code in PHP: $text = gzcompress($text); // send $text to a python server Then in python I have the following code: text = request.POST.get('text', '') new_text = zlib.decompress(text) But this fails because the decompress function needs bytes and I am passing it a string. Does anyone know how to decompress a string in python that was compressed in php? PS: I am not particularly interested in a specific algorithm or function. 来源： https://stackoverflow.com/questions

问题 I have a large local file. I want to upload a gzipped version of that file into S3 using the boto library. The file is too large to gzip it efficiently on disk prior to uploading, so it should be gzipped in a streamed way during the upload. The boto library knows a function set_contents_from_file() which expects a file-like object it will read from. The gzip library knows the class GzipFile which can get an object via the parameter named fileobj ; it will write to this object when compressing

问题 Rails 3.1 has a convenient system which can compress files into .gz files. However, instead what I've done is I've moved all the asset files that are created with assets:precompile to a static webserver. This all works, but how can I get nginx to serve the .gz files normally? 回答1: 1) ensure you have Nginx > 1.2.x (to proper headers modifications) and compile with --with-http_gzip_static_module option 2) Enable this option gzip on (to serve back-end response with gzip header) 3) Setup assets
