Java将字节转换为二进制安全字符串 [英] Java convert bytes to binary safe string

问题描述

我有一些以字节为单位的数据，我想将它们放入Redis，但是Redis仅接受二进制安全字符串，并且我的数据具有一些二进制非安全字节.那么如何将这些字节转换为二进制安全字符串，以便可以将它们保存到Redis?

I have some data in bytes, and I want to put them into Redis, but Redis only accepts binary safe string, and my data has some binary non-safe bytes. So how can I convert these bytes into binary safe string so that I can save them to Redis?

Base64对我有用，但是它使数据更大，还有更好的主意吗?

Base64 works for me, but it makes data larger, any better idea?

更新:我想将protobuf对象序列化为Redis，并且序列化的数据为'\ x00'，所以当我从Redis读取数据时，无法将数据反序列化为对象.然后我尝试了base64，它可以正常工作，但是尺寸更大.

UPDATE: I want to serialize my protobuf object to Redis, and the serialized data has '\x00', so when I read the data from Redis, I can not deserialize the data to object. Then I tried base64, it works fine, but with larger size.

所以我想弄清楚如何安全地以较小的大小将二进制数据(protobuf对象)序列化到Redis

So I want to figure out how to serialize binary data (protobuf object) to Redis safely and with smaller size

推荐答案

您可以尝试ISO-8859-1编码.这在字节和字符之间使用了一对一的映射.

You could try ISO-8859-1 encoding. This uses a one to one mapping between bytes and chars.

这仍然可能导致损坏，具体取决于Redis为什么需要此二进制安全"字符串.您可能必须使用base64.

This could still result in corruption depending on why Redis need this "binary safe" string. You may have to use base64.
