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();
