I will introduce thebase64command-line utility that you can use to encode and decode data. Finally, I provide some practical examples of Base64 encoding that you will likely encounter as a sysadmin.

-d, --decode 解码数据 -i, --ignore-garbag 解码时忽略非字母字符 -w, --wrap=字符数 在指定的字符数后自动换行(默认为76),0 为禁用自动换行 --help显示此帮助信息并退出 --version 显示版本信息并退出 数据以 RFC 4648 规定的 base64 字母格式进行编码。
如何进行base64编码 可使用util中的Base64Helper()方法进行base64编码,参考代码如下: import { util } from '@kit.ArkTS'; @E……欲了解更多信息欢迎访问华为HarmonyOS开发者官网
with a "hedge" which is pretty good for finding base64 on the command line. It's not exhaustive, but essentially looks for longer command lines with a decent length of a base64 string, and it also has to be a valid string (one that can be decoded by the base64_decode() function....
