base64

问题 I have a String which contains some encoded values in some way like Base64. The problem is that I really don't know if it's actually Base64 (there are A-Z, a-z. 0-9, +, /) so it can be some any other code that i'm not familiar with. Is there a way or any other online site to send him an encoded input and it can tell me in which code is it? NOTE: I'm not asking how to know if my String is UTF-8 or iso-8859-1 or something like that. What I need is to know in which is my code is encoded. EDIT:

问题 I have a chat, and a JSON file where all the history is stored. All images/video/audio link to require('path to media'). However, for some reason, when using vue-cli-service serve or vue-cli-service build, webpack skips my image which is used for Emoji, not including it in dist folder, but converting it to base64 string. JSON looks like this: { type: 'emoji', author: `me`, data: { src: require('../../Media/img/smiling-face.png') } }, { type: 'text', author: `me`, data: { text: `Do you read me

问题 I am using requests to get the image from remote URL. Since the images will always be 16x16, I want to convert them to base64 , so that I can embed them later to use in HTML img tag. import requests import base64 response = requests.get(url).content print(response) b = base64.b64encode(response) src = "data:image/png;base64," + b The output for response is: response = b'GIF89a\x80\x00\x80\x00\xc4\x1f\x00\xff\xff\xff\x00\x00\x00\xff\x00\x00\xff\x88\x88"""\xffff\... The HTML part is: <img src="

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
