Python 示例

python 复制代码

def convert_encoding(input_str, from_encoding, to_encoding):
    return input_str.encode(from_encoding).decode(to_encoding)

# 使用示例
converted_str = convert_encoding("你好，世界！", "utf-8", "gbk")
print(converted_str)

Ruby 示例

ruby 复制代码

def convert_encoding(input_str, from_encoding, to_encoding)
    input_str.encode(to_encoding, from_encoding)
end

# 使用示例
converted_str = convert_encoding("你好，世界！", "UTF-8", "GBK")
puts converted_str

Java 示例

java 复制代码

public class EncodingConverter {
    public static String convertEncoding(String inputStr, String fromEncoding, String toEncoding) throws UnsupportedEncodingException {
        return new String(inputStr.getBytes(fromEncoding), toEncoding);
    }

    public static void main(String[] args) {
        try {
            String convertedStr = convertEncoding("你好，世界！", "UTF-8", "GBK");
            System.out.println(convertedStr);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
}

Go 示例

go 复制代码

package main

import (
    "fmt"
    "golang.org/x/text/encoding/simplifiedchinese"
    "golang.org/x/text/transform"
    "io/ioutil"
    "strings"
)

func convertEncoding(inputStr, fromEncoding, toEncoding string) (string, error) {
    var reader *strings.Reader
    if fromEncoding == "UTF-8" && toEncoding == "GBK" {
        reader = strings.NewReader(inputStr)
        transformer := transform.NewReader(reader, simplifiedchinese.GBK.NewEncoder())
        result, err := ioutil.ReadAll(transformer)
        if err != nil {
            return "", err
        }
        return string(result), nil
    }
    // 可以添加更多编码转换逻辑
    return inputStr, nil
}

func main() {
    convertedStr, err := convertEncoding("你好，世界！", "UTF-8", "GBK")
    if err != nil {
        fmt.Println("编码转换错误:", err)
        return
    }
    fmt.Println(convertedStr)
