DataView 是处理二进制数据的强大工具,特别是在需要从ArrayBuffer 中读取和写入不同数据类型时。 3. Blob、File Blob 和File 都是 Web API 中用于处理二进制数据的对象,但它们有一些关键的区别和联系。 Blob Blob(Binary Large Object)是一个表示不可变原始数据的接口。它主要...
Base64is a group of similarbinary-to-text encodingschemes that representbinary datain anASCIIstring format by translating it into aradix-64 representation. Base64是一种用64个可打印字符来表示任意二进制数据的方法,不能用于加密。 为什么使用Base64格式编码?
In this article we will see how to convert Base64 encoded audio data in formats like wav or mp3 back to the original binary wav/mp3 file. In fact, you can use the below methods to convert any base64 encoded data back to its binary format. Step 1: Save the base64 encoded data into...
