sun.misc.BASE64Decoder一个例子:
import sun.misc.*;
import java.awt.*;
import java.io.*;
public class Base64Decode { public static void main(String[] args) { if (args.length >= 2) {
try {
InputStream is = new FileInputStream(args[0]);
OutputStream os = new FileOutputStream(args[1]);
BASE64Decoder b64dc = new BASE64Decoder();
b64dc.decodeBuffer(is, os);
}
catch (IOException e) {
System.err.println(e);
}
} // end if } // end main
输入的是一个encode的文件,输出就是解码后的文件了。

去找找rfc的文档,我不知道具体是RFC????了。
我做过在JEditorPane里接收<Ctrl>+<Enter>键的,,,
如下:
KeyStroke stroke1 = KeyStroke.getKeyStroke (KeyEvent.VK_ENTER,ActionEvent.CTRL_MASK,true);//创建一个KeyStroke类 最后一个参数的意思是是否在Keyrelease时触发此事件
JEditorPane jEditorPane1 = new JEditorPane(); jEditorPane1.registerKeyboardAction(new ActionListener(){
//要执行的方法
public void actionPerformed(ActionEvent e){
System.out.println("OK");
}
},stroke1,JComponent.WHEN_IN_FOCUSED_WINDOW);
}
registerKeyboardAction方法的参数意思是这样的
1.ActionListener对象,可以定义你要执行的方法
2.KeyStroke 对象,定义触发事件的条件
3.何时按Ctrl+Enter时发生此事件,比如
JComponent.WHEN_IN_FOCUSED_WINDOW
JComponent.WHEN_FOCUSED等
send( in, out, "AUTH LOGIN" );
send( in, out, get64Code("user_ID") );
send( in, out, get64Code("password") );
转换方法:
public String get64Code( String code32 ){
//把字符串转换成BASE64格式
String code64 = new sun.misc.BASE64Encoder().encode(code32.getBytes());
return code64;
} 共同提高。
只有邮件内容用base64编码后才需要解码得到汉字的。(或其他,日文/泰文等)
也可能是用QuotaPrintable编码的,那就用QuotaPrintable解码。
userid,password在pop3/smtp协议里都是明文传送.
