.pack（“ h*”）]。
在Ruby中，我使用函数.pack（“ H*”）]。pack（“ m0”）将十六进制消息字符串编码为base64字符串。
前任。
msg_hex = 8308862831031591345F010101020663602A06E300000000EF934E0C5B29E50E000000000000000000000310000000004F04010000010000
msg_hex.pack("H*")].pack("m0") => gwiGKDEDFZE0XwEBAQIGY2AqBuMAAAAA75NODFsp5Q4AAAAAAAAAAAAAAxAAAAAATwQBAAABAAA=
在JavaScript中，我正在寻找一种等效方法将消息转换为64base消息。一些答案告诉使用buffer.from（msg_hex）.tostring（'Base64'），但结果是不同的。
const msg_hex = 8308862831031591345F010101020663602A06E300000000EF934E0C5B29E50E000000000000000000000310000000004F04010000010000
Buffer.from(msg_hex).toString('base64') // => ODMwODg2MjgzMTAzMTU5MTM0NUYwMTAxMDEwMjA2NjM2MDJBMDZFMzAwMDAwMDAwRUY5MzRFMEM1QjI5RTUwRTAwMDAwMDAwMDAwMDAwMDAwMzEwMDAwMDAwMDA0RjA0MDAwMDAwMDEwMDAw
.pack（“ h*”）]。javascript中Ruby的的等效方法是什么？
In Ruby, I use function .pack("H*")].pack("m0") to encode a hex message string to base64 string.
ex.
msg_hex = 8308862831031591345F010101020663602A06E300000000EF934E0C5B29E50E000000000000000000000310000000004F04010000010000
msg_hex.pack("H*")].pack("m0") => gwiGKDEDFZE0XwEBAQIGY2AqBuMAAAAA75NODFsp5Q4AAAAAAAAAAAAAAxAAAAAATwQBAAABAAA=
In Javascript, I am looking for an equivalent method to convert message to 64base message. Some answers tell useing Buffer.from(msg_hex).toString('base64'), but the result is different.
const msg_hex = 8308862831031591345F010101020663602A06E300000000EF934E0C5B29E50E000000000000000000000310000000004F04010000010000
Buffer.from(msg_hex).toString('base64') // => ODMwODg2MjgzMTAzMTU5MTM0NUYwMTAxMDEwMjA2NjM2MDJBMDZFMzAwMDAwMDAwRUY5MzRFMEM1QjI5RTUwRTAwMDAwMDAwMDAwMDAwMDAwMzEwMDAwMDAwMDA0RjA0MDAwMDAwMDEwMDAw
what is the equivalent method for .pack("H*")].pack("m0") of Ruby in Javascript?

您几乎可以在那里提供的东西。
您只需忘记告诉
buffer.from您提供的内容，如发送字符串，默认情况下它只是将其存储为字符串。但是您想要的是将源代源解码为十六进制，然后将其存储为二进制。所以做 - ＆gt;
IOW：您只是错过了第二个参数
hex。You was nearly there with what you supplied.
You just forgot to tell
Buffer.fromwhat you was supplying, as default if you send a string it's just going to store it as a string. But what you wanted was to decode the source as hex and then store as binary.So doing ->
IOW: you just missed the second parameter
hex..
