我阅读了很多关于 Base64 在客户端编码然后在服务器端解码的信息.
I read alot about Base64 encoding on client side and then decoding on the server side.
为什么不在 http 请求上使用 binary 上传和 multipart 标头?
Why not just use binary upload with multipart headers on the http request?
每种技术是否有任何优点/缺点?
Base64 将您的数据转换为二进制数据的 ASCII 表示.它允许您将数据嵌入到文本流中，例如 JSON.Base64 将传输的数据大小增加了 33%.
Base64 converts your data to an ASCII representation of the binary data. It allows you to embed your data in text streams such as JSON for example. Base64 increases the size of the data transferred by 33%.
multipart/form-data 是在 HTTP 请求中传输二进制数据的标准方式.它允许您为要传输的每个部分使用特定的编码/内容类型.在我看来，除非您有特定要求或设备/SDK 功能，否则您应该坚持分段上传.
multipart/form-data is the standard way of transferring binary data in HTTP requests. It allows you to use specific encodings / content types for each part you'd like to transfer. In my opinion, you should stick to multipart uploads unless you have specific requirements or device/SDK capabilities.
