How to download image from any web page in java

Question

hi I'm trying to download an image from a webpage. I am trying to download an image from the homepage http://www.yahoo.com. Please tell me how to pass "http://www.yahoo.com" as input. And when you open this web page, how to get an image from this page. Please give me java code to get the image from the web page.

Answer 1

(throws IOException) Image image = null; try { URL url = new URL("http://www.yahoo.com/image_to_read.jpg"); image = ImageIO.read(url); } catch (IOException e) { } 

See the javax.imageio package for more javax.imageio . This is the use of an AWT image. Otherwise, you can do:

  URL url = new URL("http://www.yahoo.com/image_to_read.jpg"); InputStream in = new BufferedInputStream(url.openStream()); ByteArrayOutputStream out = new ByteArrayOutputStream(); byte[] buf = new byte[1024]; int n = 0; while (-1!=(n=in.read(buf))) { out.write(buf, 0, n); } out.close(); in.close(); byte[] response = out.toByteArray(); 

And then you can save the image like this:

 FileOutputStream fos = new FileOutputStream("C://borrowed_image.jpg"); fos.write(response); fos.close(); 

Answer 2

If you want to save the image, and you know its URL, you can do this:

 try(InputStream in = new URL("http://example.com/image.jpg").openStream()){ Files.copy(in, Paths.get("C:/File/To/Save/To/image.jpg")); } 

You will also need to handle an IOException that may be triggered.

Answer 3

This works for me:

 URL url = new URL("http://upload.wikimedia.org/wikipedia/commons/9/9c/Image-Porkeri_001.jpg"); InputStream in = new BufferedInputStream(url.openStream()); OutputStream out = new BufferedOutputStream(new FileOutputStream("Image-Porkeri_001.jpg")); for ( int i; (i = in.read()) != -1; ) { out.write(i); } in.close(); out.close();

You are looking for a web tracked vehicle. You can use JSoup for this, here is a basic example

Answer 5

  // Do you want to download an image? // But are u denied access? // well here is the solution. public static void DownloadImage(String search, String path) { // This will get input data from the server InputStream inputStream = null; // This will read the data from the server; OutputStream outputStream = null; try { // This will open a socket from client to server URL url = new URL(search); // This user agent is for if the server wants real humans to visit String USER_AGENT = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36"; // This socket type will allow to set user_agent URLConnection con = url.openConnection(); // Setting the user agent con.setRequestProperty("User-Agent", USER_AGENT); // Requesting input data from server inputStream = con.getInputStream(); // Open local file writer outputStream = new FileOutputStream(path); // Limiting byte written to file per loop byte[] buffer = new byte[2048]; // Increments file size int length; // Looping until server finishes while ((length = inputStream.read(buffer)) != -1) { // Writing data outputStream.write(buffer, 0, length); } } catch (Exception ex) { Logger.getLogger(WebCrawler.class.getName()).log(Level.SEVERE, null, ex); } // closing used resources // The computer will not be able to use the image // This is a must outputStream.close(); inputStream.close(); } 

Answer 6

The following code loads an image from a direct link to the disk into the project directory. Also note that it uses try-with-resources .

 import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.MalformedURLException; import java.net.URL; import org.apache.commons.io.FilenameUtils; public class ImageDownloader { public static void main(String[] arguments) throws IOException { downloadImage("https://upload.wikimedia.org/wikipedia/commons/7/73/Lion_waiting_in_Namibia.jpg", new File("").getAbsolutePath()); } public static void downloadImage(String sourceUrl, String targetDirectory) throws MalformedURLException, IOException, FileNotFoundException { URL imageUrl = new URL(sourceUrl); try (InputStream imageReader = new BufferedInputStream( imageUrl.openStream()); OutputStream imageWriter = new BufferedOutputStream( new FileOutputStream(targetDirectory + File.separator + FilenameUtils.getName(sourceUrl)));) { int readByte; while ((readByte = imageReader.read()) != -1) { imageWriter.write(readByte); } } } } 

Answer 7

How to download an image is an explained blog. You can refer to this.

Answer 8

I think he wanted to specify the URL of the site, not the URL of the image. For images that have their url as src in the html code of sites, I think you could do prasing and look for <img ... src= , and if it's a URL and not a local path, use the methods in other answers to save it.
