以HTTP形式获取图片流并写入另一个图片

图片流操作：

                 // conn.getInputStream()获取url所访问图片的InputStream字节流
                 // formatName是图片的扩展名如：“jpg/gif”等
                 // Constant.PATH为新图片的地址
                 // pictureName新图片的名称
                String smsUrl  =   " http:// "   +  resConfig.getCommonShowAddress() + " / "   +  sms.getSmsUrl();
                URL url  =   null ;
                URLConnection conn  =   null ;
                url  =   new  URL(smsUrl);
                conn  =  url.openConnection();
                BufferedImage image  =  ImageIO.read(conn.getInputStream());
                String formatName  =  filePostfix.substring( 1 , filePostfix.length());
                ImageIO.write(image, formatName,  new  File(Constant.PATH, pictureName));

如果不是图片：
    jar包是uploadbean.jar
    UploadBean 使用的是javazoom.upload.UploadBean

    String filename = user.getUserName() + Constant.getDate() + ".lst";  //信息索引文件
    String bodyFileName = Constant.getDate() + ".tel"; //电话文件
    String messageFileName = Constant.getDate() + ".txt"; //彩信的文本内容。
    String pictureName = Constant.getDate() +filePostfix ;  //图片名称
    
    UploadBean upload = new UploadBean();
    upload.setParser(MultipartFormDataRequest.COSPARSER);
    upload.setWhitelist(Constant.WHITELIST);
    upload.setFolderstore(Constant.PATH);

    telStr = strBuff.toString().trim();
    FileOutputStream bodyfos = new FileOutputStream(new File(Constant.PATH, bodyFileName));
    BufferedWriter bodytbw = new BufferedWriter(new OutputStreamWriter(bodyfos, "GBK"));
    bodytbw.write("\"" + telStr + "\"");
    bodytbw.flush();
    bodytbw.close();
    bodyfos.close();

    生成的文件名称有中文。
    FileOutputStream fos = new FileOutputStream(new File(Constant.PATH, new String(filename.getBytes("GBK"))));
    BufferedWriter stdout = new BufferedWriter(new OutputStreamWriter(fos, "GBK"));
    stdout.write(sb.toString());//sb.toString()是写入文件的内容。
    stdout.flush();
    stdout.close();
    fos.close();
