右键，文件属性是UTF-8，看系统属性也是UTF-8，数据直接写死。但转为GBK后，求base64编码错误。
1234qwer我的
编码后正确的结果应该是

好吧，很多人都觉得简单，开始我也觉得，但无论怎么试和修改，就是的不出正确结果。谁能写出一段Java代码，得出这个结果
已解决。答案如下，大家参考下
public static void main(String[] args) throws UnsupportedEncodingException { String tranData0 = "1234qwer我的"; String tranData640 = ProcessMessage.Base64Encode(tranData0.getBytes()); System.out.println("UTF-8的："+tranData640); String tranData = "1234qwer我的"; tranData=new String(tranData.getBytes("utf-8"),"gbk"); String tranData64 = ProcessMessage.Base64Encode(tranData.getBytes()); System.out.println("错误的："+tranData64); String tranData3 = "1234qwer我的"; tranData=new String(tranData3.getBytes("utf-8"),"gbk"); String tranData643 = ProcessMessage.Base64Encode(tranData.getBytes("GBK")); System.out.println("也是错误的："+tranData643); String tranData2 = "1234qwer我的"; tranData=new String(tranData2.getBytes("utf-8")); String tranData642 = ProcessMessage.Base64Encode(tranData.getBytes("GBK")); System.out.println("正确的："+tranData642); }再来一个GBK转UTF-8编码的，看看你能猜对不？
public class CodeTest { public static void main(String[] args) throws UnsupportedEncodingException { String tranData0 = "1234qwer我的"; String tranData640 = Base64Encode(tranData0.getBytes()); System.out.println("GBK的："+tranData640); String tranData = "1234qwer我的"; tranData=new String(tranData.getBytes("gbk"),"UTF-8"); String tranData64 = Base64Encode(tranData.getBytes()); System.out.println("我TM什么都不是："+tranData64); String tranData3 = "1234qwer我的"; tranData3=new String(tranData3.getBytes("utf-8"),"gbk"); String tranData643 = Base64Encode(tranData3.getBytes("GBK")); System.out.println("你以为是GBK，但实际是utf-8的："+tranData643); String tranData2 = "1234qwer我的"; // tranData=new String(tranData2.getBytes("utf-8")); String tranData642 = Base64Encode(tranData2.getBytes("UTF-8")); System.out.println("utf-8的："+tranData642); } public static String Base64Encode(byte[] content){ return new sun.misc.BASE64Encoder().encode(content); } }
