Convert boolean value to string using strconv.FormatBool function

Use the strconv.FormatBool function to convert Boolean values ​​to strings

In the Go language, we often need to convert Boolean values ​​to strings. In this case, we can use the strconv.FormatBool function in the strconv package. This function accepts a Boolean value as a parameter and returns the corresponding string representation.

The sample code is as follows:

package main

import (
    "fmt"
    "strconv"
)

func main() {
    // 将布尔值转换为字符串
    b := true
    s := strconv.FormatBool(b)
    fmt.Println(s)

    // 将字符串转换为布尔值
    s = "false"
    b, err := strconv.ParseBool(s)
    if err == nil {
        fmt.Println(b)
    } else {
        fmt.Println("字符串转换为布尔值失败:", err)
    }
}

In the above sample code, first we define a Boolean value b as true, and then use the strconv.FormatBool function to convert it into a string and store it in the variable s middle. Finally, the value of the string s is printed out through the fmt.Println function.

Also, in the second half of the sample code, we also demonstrate how to convert a string to a Boolean value. First define a string s as "false", then use the strconv.ParseBool function to convert it to a Boolean value and store it in the variable b. It should be noted that during the conversion process, if the string cannot be parsed correctly into a Boolean value, an error will be returned. Therefore, you need to use the error type variable err to determine whether the conversion is successful.

Through these sample codes, we can easily convert between Boolean values ​​and strings to meet the needs of different scenarios. Whether you are storing a Boolean value in a database, as a parameter in an HTTP request, or for other processing, you can use the strconv.FormatBool function.

To summarize, using the strconv.FormatBool function can easily convert Boolean values ​​to strings. In the Go language, this function is one of the common tools for processing conversions between Boolean values ​​and strings, which can help us process data more flexibly.
