golang bytes to text

Golang is a programming language, and one of its features is that it supports bytes processing. When we process some data, we often need to convert bytes into text. This article will introduce several methods of converting bytes to text in Golang.

1. Use the string function to convert

To convert a byte array into a string, you can use Golang's built-in string function.

func byteToString(arr []byte) string {

return string(arr)

}

2. Use the bytes library to convert

There is a bytes in Golang’s standard library Package that provides many bytes-related functions, including methods for converting bytes to text.

func bytesToString(arr []byte) string {

return string(bytes.TrimSpace(arr))

}

3. Use the strconv library to convert

In addition, we can also use the strconv library The Parse* series of functions convert bytes into values ​​of the corresponding type. For example, the ParseInt function converts bytes into integers.

func byteToInt(arr []byte) (int, error) {

return strconv.Atoi(string(bytes.TrimSpace(arr)))

}

4. Conversion using bufio library

bufio library also provides A method to convert bytes to text. Among them, bufio.NewScanner is used to initialize a Scanner structure. It has two methods, Bytes and Text, which return byte slices and strings respectively.

func byteToText(arr []byte) string {

scanner := bufio.NewScanner(bytes.NewReader(arr))
scanner.Split(bufio.ScanWords)
var text []string
for scanner.Scan() {
    text = append(text, scanner.Text())
}
return strings.Join(text, " ")

}

Summary

In Golang, there are many ways to convert bytes to text . It is feasible to use the string function, bytes library, strconv library and bufio library. Which method to choose needs to be weighed based on the actual situation, taking into account factors such as conversion efficiency, accuracy, and readability. During use, appropriate conversion methods should be selected based on different data types.
