In go language, byte is actually an alias for uint8, and byte and uint8 can be directly transferred.
At present, ints in the range 0~255 can only be converted into byte.
func Int64ToBytes(num int64) []uint8 {
var buffer
err := (&buffer, , num)
if err != nil {
("int64 to[]uint8 failed %v", err)
}
return ()
}
When using(), you should pay attention to some issues:
Write writes the binary representation of data into w.
Data must be a fixed-size value or a slice of fixed-size // values, or a pointer to such data.
Boolean values encode as one byte: 1 for true, and 0 for false.
Bytes written to w are encoded using the specified byte order and read from successive fields of the data. When writing structs, zero values are written for fields with blank (_) field names.
My translation is like this (I don’t have good English, don’t blame me!)
Write writes the binary representation of the data to w.

The Boolean value is encoded as one byte: 1 means true and 0 means false.
The bytes written to w are encoded in the specified byte order and read from consecutive fields of the data.
When writing to a structure, a zero value name is written to the blank (_) field.
Supplement: Golang's json conversion problem with json library is a relatively easy trap for json library.
Similar to this CA, if the instance is converted into a string.
type CA struct {
List []uint8
}
func main() {
ca := CA{[]uint8{1,2,3,4,5,6,7,8,9,0}}
r, _ := (ca)
(string(r)) //{"List":"AQIDBAUGBwgJAA=="}
}
What we want is to have a normal json. Only an 8-bit json library such as int8 byte uint8 will be processed as a string for us. If you want to solve it, you can't use these types if you want to use them. You need to use 16 32 64-bit numbers to convert them into a json string normally.
{"List":[1,2,3,4,5,6,7,8,9,0]}
But don't worry. Unmarshal, a json string we think is unwanted, will get the desired result.
If it is cross-language json communication, be careful.
The above is personal experience. I hope you can give you a reference and I hope you can support me more. If there are any mistakes or no complete considerations, I would like to give you advice.
