Use strconv.QuoteToASCII function in golang to convert string to ASCII code representation

Use the strconv.QuoteToASCII function in golang to convert the string into ASCII code representation

In the process of programming with Golang, we often encounter the need to The string is converted to ASCII code representation. ASCII code is a common character encoding standard that can map characters into integers to facilitate processing and transmission in computer systems.

In Golang, we can use the QuoteToASCII function in the built-in strconv package to perform string conversion. The function of this function is to convert non-ASCII characters in the string into corresponding Unicode escape sequences.

The following is a specific code example that shows how to use the strconv.QuoteToASCII function to convert a string to ASCII code representation:

package main

import (
    "fmt"
    "strconv"
)

func main() {
    str := "Hello, 世界!"

    // 使用QuoteToASCII函数将字符串转换为ASCII码表示
    asciiStr := strconv.QuoteToASCII(str)

    fmt.Println(asciiStr) // 输出： "Hello, u4E16u754C!"
}

In the above code, we first define a containing A string of non-ASCII characters str, which contains a Chinese character "世界". Next, we use the strconv.QuoteToASCII function to convert this string to ASCII code representation, and save the result in the asciiStr variable.

Finally, we use the fmt.Println function to print out the asciiStr. As you can see, the output result is "Hello, u4E16u754C!". Among them, u4E16 and u754C are the Unicode escape sequences of the two Chinese characters "World" respectively. In this way, we successfully converted the string into ASCII code representation.

It should be noted that the QuoteToASCII function not only converts non-ASCII characters into Unicode escape sequences, but also escapes special characters in the string. For example, `
represents a newline character, ` represents a carriage return character, etc.

In addition, if we want to remove the quotes in the escape sequence, we can use the strings.Trim function to process:

package main

import (
    "fmt"
    "strconv"
    "strings"
)

func main() {
    str := "Hello, 世界!"

    // 使用QuoteToASCII函数将字符串转换为ASCII码表示
    asciiStr := strconv.QuoteToASCII(str)

    // 去掉转义序列中的引号
    trimStr := strings.Trim(asciiStr, """)

    fmt.Println(trimStr) // 输出： Hello, u4E16u754C!
}

In the above code, we pass Use the strings.Trim function to remove the quotes in the escape sequence to get the final result Hello, u4E16u754C!.

Through the above example, we can see that it is very convenient to use the strconv.QuoteToASCII function in golang to convert a string into ASCII code representation. This is very useful in some scenarios, such as encoding strings containing special characters during network transmission. We can use this function to process strings according to specific needs, and handle escape sequences as needed.
