How to convert Golang string to byte array
This article focuses on "how to convert Golang strings and byte arrays". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn how to convert Golang strings to byte arrays.
String and byte array?
String is one of the most commonly used basic data types in Go language. it is essentially a read-only character array. Although strings are often regarded as a whole, strings are actually a continuous memory space.
Another type byte (Byte) in Go language. In ASCII, an English letter occupies one byte of space and a Chinese character occupies two bytes of space. English punctuation accounts for one byte and Chinese punctuation accounts for two bytes. The elements in an Byte array correspond to an ASCII code.
Second, detailed code 1. Byte to string
The code is as follows (example):
Func BytesToString (data [] byte) string {return * (* string) (unsafe.Pointer (& data)) 2. String to byte array
The code is as follows (example):
Func StringToBytes (data string) [] byte {return * (* [] byte) (unsafe.Pointer (& data))} 3. Run the test completely
The code is as follows (example):
Func BytesToString (data [] byte) string {return * (* string) (unsafe.Pointer (& data))} func StringToBytes (data string) [] byte {return * (* [] byte) (unsafe.Pointer (& data))} func main () {str: = "hello world!" Fmt.Println (str) a: = StringToBytes (str) fmt.Println (a) b: = BytesToString (a) fmt.Println (b)}
Result (example):
Successfully translated Hello world!
