Java中如何对URL进行编码和解码

?Java?,????java.net.URLEncoder?java.net.URLDecoder??URL??????????????????????application/x-www-form-urlencoded MIME??????

1. ?URL????:

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;

public class URLEncodingExample {
    public static void main(String[] args) {
        String url = "https://example.com/search?q=????";
        try {
            String encodedUrl = URLEncoder.encode(url, "UTF-8");
            System.out.println("Encoded URL: " + encodedUrl);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
}

2. ?URL????:

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;

public class URLDecodingExample {
    public static void main(String[] args) {
        String encodedUrl = "https://example.com/search?q=你好世界";
        try {
            String decodedUrl = URLDecoder.decode(encodedUrl, "UTF-8");
            System.out.println("Decoded URL: " + decodedUrl);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
}

??:???URLEncoder.encode()?URLDecoder.decode()?,???????(?"UTF-8")?????URL???????????????????
