URLEncoder和URLDecoder轉碼

目前看是為了解決網絡傳輸的中文亂碼問題

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;
public class URLDecoderTest {
public static void main(String[] args) throws UnsupportedEncodingException {
// 將application/x-www-from-urlencoded字符串轉換成普通字符串
        String keyWord = URLDecoder.decode("%E6%9D%8E%E5%88%9A", "UTF-8");
        System.out.println(keyWord);
// 將普通字符創轉換成application/x-www-from-urlencoded字符串
        String urlString = URLEncoder.encode("愛我中華", "UTF-8");
        System.out.println(urlString);
    }
}
