1.java使用BASE64对文字编码的案例
import java.io.IOException;
public class Test {
/ **
* 编码
* @param bstr
* @return String
* /
public static String encode(byte[] bstr){
return new sun.misc.BASE64Encoder().encode(bstr);
}
/ **
* 解码
* @param str
* @return string
* /
public static byte[] decode(String str){
byte[] bt = null;
try {
sun.misc.BASE64Decoder decoder = new sun.misc.BASE64Decoder();
bt = decoder.decodeBuffer( str );
} catch (IOException e) {
e.printStackTrace();
}
return bt;
}
/ **
* @param args
* /
public static void main(String[] args) {
test te = new test();
String aa = "更多更多";
aa = te.encode(aa.getBytes());
System.out.println("----aa:"+aa);
String str = aa;
String str2 = new String(te.decode(str));
System.out.println("-----str2:"+str2);
}
}
2.java使用BASE64对图片编码的案例
package palmcity.cpndservice.tool;
import java.io.FileInputStream;
import java.io.RandomAccessFile;
public class ImageTool {
/ **
* 图片BASE64 编码
* /
public static String getPicBASE64(String picPath) {
String content = null;
try {
FileInputStream fis = new FileInputStream(picPath);
byte[] bytes = new byte[fis.available()];
fis.read(bytes);
content = new sun.misc.BASE64Encoder().encode(bytes); 具体的编码方法
fis.close();
System.out.println(content.length());
} catch (Exception e) {
e.printStackTrace();
}
return content;
}
/**
* 对图片BASE64 解码
*
* /
public static void getPicFormatBASE64(String str, String picPath) {
try {
byte[] result = new sun.misc.BASE64Decoder().decodeBuffer(str
.trim());
RandomAccessFile inOut = new RandomAccessFile(picPath, "rw"); r,rw,rws,rwd
用FileOutputStream亦可
inOut.write(result);
inOut.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
