接下来,我们需要将输入流写入到文件中,实现文件下载。 // 创建输出流OutputStreamoutputStream=newFileOutputStream("sample.zip");// 设置缓冲区byte[]buffer=newbyte[1024];intlen;// 将输入流写入文件while((len=inputStream.read(buffer))!=-1){outputStream.write(buffer,0,len);}// 关闭流inputStream....
1. 使用Java下载zip文件 在Java中,我们可以使用URLConnection和InputStream来下载zip文件。下面是一个简单的示例代码,用于从指定URL下载zip文件: importjava.io.*;importjava.net.URL;importjava.net.URLConnection;publicclassDownloadZipFile{publicstaticvoidmain(String[]args){StringfileUrl="StringsaveDir="/path/t...
publicFile zipAttachFile(String filePathDir, List<String>urlFileList, String memberId) throws Exception { filePathDir = "/home/file"; File zipFileDir=newFile(filePathDir);if(!zipFileDir.exists()) { zipFileDir.mkdir(); } List<File> fileList =newArrayList<>();for(String fileUrl : urlFil...
向zip输出流写入文件(ZipEntry), 如果有多个就循环下面五行代码。 注意: 如果文件重名,会ZipOutputStream会抛出ZipException path = imgId + File.separator + "正面.jpg"; zos.putNextEntry(new ZipEntry(path)); // 获取要写入ZipEntry的内容 byte[] data = downloadImageFromURL("http://localhost:8098/...
