什么是 Base64?· What is Base64?
Base64 是一种将二进制数据用可打印字符表示的编码方式,常用于在文本环境中传输图片、文件片段或令牌等数据。
Base64 is an encoding scheme that represents binary data using printable characters. It’s often used to move images, small files, or tokens through text-only channels. -
常见使用场景 · Common Use Cases
在前端或接口调试中,Base64 常用于:
In web development or API debugging, Base64 is often used for:
– 将图片/文件嵌入到 JSON、HTML 或 CSS 中
– Embedding images/files inside JSON, HTML or CSS
– 对 Token、配置参数做简单封装(并非加密)
– Wrapping tokens or config params in a simple, non-encrypted form
– 在不方便传输二进制数据的场景中替代原始二进制格式
– Transferring data in environments that don’t support raw binary formats -
注意:Base64 ≠ 加密 · Note: Base64 ≠ Encryption
Base64 只是编码(Encoding),不是加密(Encryption),任何人都可以轻易解码得到原文,因此不适合作为安全手段使用。
Base64 is encoding, not encryption. Anyone can reverse it, so it should not be treated as a security mechanism.
