将ZIP转换为字节数组而不将输出保存到文件

Question

        InputStream is = null;  
        OutputStream os = null; 
        is = new FileInputStream("C:/Users/DarkHorse/Desktop/WebServicesTesting/PolicyCredit.zip");  
        os = new FileOutputStream("D:/EclipseTestingFolder/EncodedFile1.txt");  
        int bytesRead = 0;  
        int chunkSize = 10000000;  
        byte[] chunk = new byte[chunkSize];  
        while ((bytesRead = is.read(chunk)) > 0) 
        {  
         byte[] ba = new byte[bytesRead]; 
         for(int i=0;i<ba.length;i++)
                {
                    ba[i] = chunk[i];                       
                } 
             byte[] encStr = Base64.encodeBase64(ba);

             os.write(encStr);            
         } 

        os.close();
        is.close();
}

您需要创建Base 64编码数据的字符串表示。

System.out.println( new String(encStr, Charset.forName("UTF-8")));

这里是基于64打印问题的一些其他示例
