Java 根据网络地址URL获取文件

一、功能需求

系统需要根据提供的文件地址URL获取该文件,代码实现如下:

二、解决办法

      private static File getFileByHttpURL(String path){        String newUrl = path.split("[?]")[0];        String[] suffix = newUrl.split("/");        //得到最后一个分隔符后的名字        String fileName = suffix[suffix.length - 1];        File file = null;        InputStream inputStream = null;        OutputStream outputStream = null;        try{            file = File.createTempFile("report",fileName);//创建临时文件            URL urlFile = new URL(newUrl);            inputStream = urlFile.openStream();            outputStream = new FileOutputStream(file);            int bytesRead = 0;            byte[] buffer = new byte[8192];            while ((bytesRead=inputStream.read(buffer,0,8192))!=-1) {                outputStream.write(buffer, 0, bytesRead);            }        }catch (Exception e) {            e.printStackTrace();        }finally {            try {                if (null != outputStream) {                    outputStream.close();                }                if (null != inputStream) {                    inputStream.close();                }            } catch (Exception e) {                e.printStackTrace();            }        }        return file;    }
