在这个示例中,base64_encode 和base64_decode 函数需要你自己实现或使用现有的库。Linux 系统通常提供了 libb64 或其他第三方库来处理 Base64 编码和解码。 常见问题及解决方法 问题:编码后的数据比原始数据长。 原因:Base64 编码会增加大约 33% 的额外空间,因为每三个字节的数据会被转换为四个字符。 解决方
import base64 def decode_base64_to_bin(input_file, output_file): # 读取Base64编码的文本文件 with open(input_file, 'r') as file: base64_data = file.read() # 解码Base64数据为二进制 binary_data = base64.b64decode(base64_data) # 将解码后的二进制数据写入新的二进制文件 with open(ou...

Base64 encoding uses printable characters to encode binary data. This enables another interesting use case: You can encode multiline files into Base64 strings. While rare, you may come across software or scripts that accept an entire configuration file as a Base64-encoded string. Consider the co...

很多语言都有内置的 base64 encode 以及 decode 函数。比如 PHP 里有base64_encode()函数: 复制代码<?php$file="1.gif";// 文件路径if($fp=fopen($file,"rb",0)) {$binary=fread($fp,filesize($file));// 文件读取fclose($fp);$base64=base64_encode($binary);// 转码echo$base64;// 显示base...
