Is It More Efficient to Put Raw Image Data in the Src Attr?

和自甴很熟 提交于 2019-12-09 16:38:22
问题 I recently found out that the src attribute of an image allows you to put raw base 64 image data straight into it. Am i right in supposing this is technically more efficient than a separate image file as additional requests for the images don't have to be made? Or is the overhead so small that it's not worth it? Also, assuming i ended up doing this, what would be the best way to get that raw data? (out of, say, an image i whipped up in paint?) 回答1: It depends on what you mean by "more

问题 Is there any URL google has that contains the raw data for the file? using https://drive.google.com/file/d/FILE_ID just takes you to a 'share' section of the file... say I have a .js file on GDrive. If you go to their share link, they have a share page. Is there any link to get the raw javascript from the file, as to use in a <script src="google_link_or_whatever"> ? 回答1: NOTE - THIS WAS THE SOLUTION BUT IT NO LONGER WORKS - SEE COMMENT BY @Bobby Fritze below No API's and no JS necessary.

How to get the raw HTML source code for a page by using Ruby or Nokogiri?

蓝咒 提交于 2019-12-04 12:53:33
I'm using Nokogiri (Ruby Xpath library) to grep contents on web pages. Then I found problems with some web pages, such as Ajax web pages, and that means when I view source code I won't be seeing the exact contents such as <table> , etc. How can I get the HTML code for the actual content? Don't use Nokogiri at all if you want the raw source of a web page. Just fetch the web page directly as a string, and then do not feed that to Nokogiri. For example: require 'open-uri' html = open('http://phrogz.net').read puts html.length #=> 8461 puts html #=> ...raw source of the page... If, on the other

Swift Siesta access response raw data

问题 I've in my API a method that return a content of PDF file. How can I access the raw data of response in success callback? 回答1: All Siesta responses start out as raw data (in the form of the Foundation type Data ), then run through the transformer pipeline. The default transformer pipeline parses JSON, text, and images based on the Content-type header sent by the server. That list doesn’t include PDF, so if your server is sending a content type of application/pdf (or anything that isn’t a JSON
