编码和解码代码的实现取决于你想要编码和解码的数据类型以及你希望使用的编程语言。以下是一些常见编程语言中编码和解码的示例代码:
Python 示例
```python
编码
text = "你好"
encoded_text_utf8 = text.encode('utf-8')
encoded_text_gbk = text.encode('gbk')
print(encoded_text_utf8.hex()) 输出: e4bda0e5a5bd
print(encoded_text_gbk.hex()) 输出: c4e3bac3
解码
decoded_text_utf8 = bytes.fromhex('e4bda0e5a5bd').decode('utf-8')
decoded_text_gbk = bytes.fromhex('c4e3bac3').decode('gbk')
print(decoded_text_utf8) 输出: 你好
print(decoded_text_gbk) 输出: 你好
```
Java 示例
```java
import java.nio.charset.StandardCharsets;
public class Decoder {
public static void main(String[] args) {
String input = "EncodedString";
String decodedOutput = decode(input);
System.out.println("Decoded Output: " + decodedOutput);
}
public static String decode(String input) {
return new String(input.getBytes(StandardCharsets.UTF_8), StandardCharsets.UTF_8);
}
}
```
C++ 示例
```cpp
include include include include std::string encode(const std::string& input) { std::stringstream ss; for (char c : input) { ss << std::hex << std::setw(2) << std::setfill('0') << static_cast } return ss.str(); } std::string decode(const std::string& encoded) { std::stringstream ss(encoded); std::string result; while (ss >> std::hex >> result) { result += result; } return result; } int main() { std::string input = "hello world!"; std::string encoded = encode(input); std::string decoded = decode(encoded); std::cout << "Encoded: " << encoded << std::endl; std::cout << "Decoded: " << decoded << std::endl; return 0; } ``` JavaScript 示例 ```javascript // 编码 var str1 = "这里是要编码的字符串%……&包含特殊字符1234"; var str2 = encodeURIComponent(encodeURIComponent(str1)); // 解码 var str1_decoded = decodeURIComponent(decodeURIComponent(str2)); console.log(str1_decoded); ``` 这些示例展示了如何在不同编程语言中实现基本的编码和解码功能。根据你的具体需求,你可能需要调整这些示例以适应不同的编码格式和数据类型。
