How to Compress JSON with ASP?

由 梦想的初衷 提交于 2020-01-10 04:20:07
问题 I have a large JSON data string that's 757KB. I tried GZIP'ing it, which successfully reduced file size down to 143KB. But, in it's GZIP'ed state, my JQUERY function can't make use of the compressed JSON data. Any suggestions on how to compress JSON in an IIS/ASP environment and still be able to use the JSON data in a JQUERY function? 回答1: Hope this helps: Activate Dynamic Compression Open SystemDir (C:\Windows\System32) and find this file: inetsvr\config\applicationhost.config Find the

gzip compression is not detected by PageSpeed Insights (node.js)

由 陌路散爱 提交于 2020-01-07 07:43:48
问题 I build my gzip-files with gulp ( gulp-gzip ) and use them with npm package connect-gzip-static : var app = express(); var serveStatic = require('connect-gzip-static'); //... app.use(serveStatic(__dirname)).listen(3000); However, PageSpeed Insights does not detect the gzip compression. But google chrome developer console it says: Response Headers: Content-Encoding: gzip. Also other seo testing tools are detecting gzip. Why Google doesen't ? I gziped all html, js, css. Should I also gzip svg's

gzip compression results in empty response on bad request, works fine otherwise

问题 I am doing a HTTP POST request from a web client using angular with the following header: Accept-Encoding: gzip, deflate, br The server response content-type is application/json. When the response status is 200, everything works fine, my response has a body that I can see from the client. However, when the response status is 400, the response body is empty according to the client, but I am certain I am populating it on the server. Also, if I remove "gzip" from the request header above (no

Open compressed file directly with argparse

由 走远了吗. 提交于 2020-01-07 03:06:28
问题 Can I open a gzip file directly with argparse by changing the type=argparse.FileType() to some gzip type? It's not in the docs, so I'm not sure if argparse even suppoets compressed file types... 回答1: First, the type parameter is a function or other callable that converts a string into something else. That's all. argparse.FileType is factory class that ends up doing something close to: def filetype(astring): mode = 'r' # or 'w' etc. try: f = open(astring, mode) except IOError: raise argparse

gzip partial modification and re-compression

由 不羁的心 提交于 2020-01-07 02:58:26
问题 I am unfamiliar with compression algorithms. Is it possible with zlib or some other library to decompress, modify and recompress only the beginning of a gzip stream and then concatenate it with the compressed remainder of the stream? This would be done in a case where, for example, I need to modify the first bytes of user data (not headers) of a 10GB gzip file so as to avoid decompressing and recompressing the entire file. 回答1: No. Compression will generally make use of the preceding data in

How to change deflate stream output format(raw, zlib, gzip) when use zlib?

由 陌路散爱 提交于 2020-01-06 07:28:20
问题 Zlib can output three format, I try to search the docs and zlib.h , but can't find a clear explanation about the options, anyone have any ideas? 回答1: From the zlib.h documentation of deflateInit2() : windowBits can also be -8..-15 for raw deflate. In this case, -windowBits determines the window size. deflate() will then generate raw deflate data with no zlib header or trailer, and will not compute a check value. windowBits can also be greater than 15 for optional gzip encoding.
