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

Use the strconv.QuoteToASCII function to convert a string into an ASCII code representation

Foreword:
In the field of computer programming, it is often necessary to convert strings according to certain rules. ASCII code is the most common character encoding method, used to represent characters in computers.

Introduction:
The strconv package in the Go language provides a series of functions for converting between strings and other types. Among them, the strconv.QuoteToASCII function can convert a string into an ASCII code representation, that is, convert non-ASCII characters into an escape sequence in xhh format.

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

package main

import (
    "fmt"
    "strconv"
)

func main() {
    str := "Hello, 世界！"
    fmt.Println("原始字符串:", str)
    quotedStr := strconv.QuoteToASCII(str)
    fmt.Println("转换后的字符串:", quotedStr)
}

Code description:
In the above code, we first define a string str, which contains the Chinese character "World". Then use the strconv.QuoteToASCII function to convert the string to ASCII code representation, and assign the result to the quotedStr variable. Finally, the original string and the converted string are printed by calling the fmt.Println function.

Running results:
The running results of the code are as follows:

原始字符串: Hello, 世界！
转换后的字符串: "Hello, u4e16u754cuff01"

As can be seen from the running results, the Chinese characters in the original string are converted into escape sequences in xhh format .

Note:
When using the strconv.QuoteToASCII function, you need to pay attention to the following points:

1. This function will ASCII characters are converted to escape sequences in xhh format.
2. The converted string will be wrapped in double quotes.
3. If the string contains double quotes, it will be represented by the escape sequence ".
4. If the string itself contains the escape sequence, it will not be converted.

Conclusion:
By using the strconv.QuoteToASCII function, we can convert a string into an ASCII code representation, which is very useful in some situations. For example, when dealing with special characters and non-ASCII characters In scenarios, we can use this function to convert strings.

Overall, the strconv package of Go language provides many convenient functions that can help us convert between different data types. In actual programming, we can flexibly use these functions according to specific needs to improve programming efficiency and code readability.
