encoding

问题 So i've got a video file and the path to it (e.g. /outerfolder/innerfolder/video.mp4 ). I now want to encode this video with Base64 in JS so that I am able to store it in a database. If you could help me with the encoding of the video file, I would be very thankful. Thanks in advance. 回答1: You could encode the file with the following function to convert your file to an ArrayBuffer: [update] //<input type=file id="encondeMP4"> var encodeMP4 = document.getElementById('encondeMP4'); You now add

问题 I have to following string which i get from share point : \u002fsites\u002fblabla\u002fShared Documents\u002fkittens.xml and i'm trying to convert it to : /sites/blabla/Shared Documents/kittens.xml I googled it and found that it is Unicode encoded, but i couldn't find anything that converts it, technically i can write a small function that converts all the "\u002f" to "/" but i don't think it is the right thing to do. If any one can shed some light on this matter it would be very helpful.

问题 What encoding does Windows use for command line parameters passed to programs started in a cmd.exe window? The encoding of command line parameters doesn't seem to be affected by the console code page set using chcp (I set it to UTF-8, code page 65001 and use the Lucida Console font.) If I paste an EN DASH, encoded as hex E28093, from a UTF-8 file into a command line, it is displayed correctly in the cmd.exe window. However, it seems to be translated to a hex 96 (an ANSI representation) when

问题 I'm trying to write a program that checks if a circle contains another circle, if a certain point is inside a circle, or the one I'm having trouble with, if a circle overlaps with another circle. import javafx.scene.shape.Circle; public class Problem10_11 { public static void main(String[] args) { //Create circle with certain parameters. Circle2D c1 = new Circle2D(2, 2, 5.5); //Create output which will be tested by all our methods. System.out.println("The area for circle 1 is " +c1.getArea()+

问题 I found one tricky place and couldn't find any answer why this exactly happen. The main problem is how long is string. Whether it contains one or two character. Code: public class App { public static void main(String[] args) throws Exception { char ch0 = 55378; char ch1 = 56816; String str = new String(new char[]{ch0, ch1}); System.out.println(str); System.out.println(str.length()); System.out.println(str.codePointCount(0, 2)); System.out.println(str.charAt(0)); System.out.println(str.charAt

问题 I need to form a 'multipart/form-data' REST request with jpeg image and JSON file as the content.I am stuck with encoding the 'multipart/form-data' as a zip file. Can someone tell me, how I can achieve this with groovy RESTClient? I could not find any documentation regarding this. 回答1: As it can be seen in the docs RESTClient extends HTTPBuilder . HTTPBuilder has a getEncoder method that can be used to add dedicated encoder (with type and method). See the following piece of code: import org

问题 I am using Flask and Angular JS to process POST request and I am wondering why the Chrome request header has application/json;charset=UTF-8 compared to FireFox application/json;charset=utf-8 . Note the difference is only the chrome capitalizes UTF while FireFox doesnt (utf). This is probably related to SO: MySQL UTF8 for Chrome, UTF8 for IE, but HEADER UTF8 for Chrome and UTF-8 for IE? but I wasn't able to understand completely. I am not using any meta tag in the html, maybe that is the
