下面是一个示例代码,演示了如何根据请求URL创建文件: importjava.io.File;importjava.io.IOException;publicclassCreateFileFromURL{publicstaticvoidmain(String[]args){Stringurl="StringfileName=url.substring(url.lastIndexOf('=')+1);Filefile=newFile(fileName);try{if(file.createNewFile()){System.out.print...
接着,我们需要创建一个输出流,用于将文件内容写入本地文件。 // 创建输出流FileOutputStreamout=newFileOutputStream("output.txt"); 1. 2. 步骤5:读取文件内容并保存 最后,我们可以通过输入流读取文件内容,并将其保存到本地文件中。 // 读取文件内容并保存intbytesRead;byte[]buffer=newbyte[1024];while((by...
//文件保存位置 File saveDir =new File(savePath); if(!saveDir.exists()){ saveDir.mkdir(); } File file =new File(saveDir+File.separator+fileName); FileOutputStream fos =new FileOutputStream(file); fos.write(getData); if(fos!=null){ fos.close(); } if(inputStream!=null){ inputStre...
URL website =null; ReadableByteChannel rbc =null; FileOutputStream fos =null; try{ website =newURL(remoteFilePath); rbc = Channels.newChannel(website.openStream()); fos =newFileOutputStream(localFilePath);//本地要存储的文件地址 例如:test.txt fos.getChannel().transferFrom(rbc,0, Long.MA...
读取输入流中的数据,并将其写入到本地文件中:使用FileOutputStream将输入流中的数据写入到本地文件中。 java FileOutputStream outputStream = new FileOutputStream("localfile.ext"); byte[] buffer = new byte[1024]; int bytesRead; while ((bytesRead = inputStream.read(buffer)) != -1) { outputStr...
URLurl=newURL(imageUrl); InputStreamin=url.openStream(); // 构建保存路径 String[] split = imageUrl.split("/"); StringfileName=split[split.length -1]; Filefile=newFile(savePath + fileName); if(!file.exists()) { file.createNewFile(); ...
URL url=new URL("http://example.com/file.txt"); 请确保URL是有效的,否则在这一步可能会抛出MalformedURLException。 步骤2: 打开URLConnection 接下来,使用url对象的openConnection()方法来创建一个URLConnection对象。这个对象代表了应用程序和URL之间的通信链接。
