(jak) mogę pobrać obraz za pomocą JSoup?

Question

Już wiem, gdzie jest obraz, ale dla uproszczenia chciałem pobrać obraz za pomocą samego JSoup. (To jest uproszczenie coraz cookie, referrer, itp)

To, co mam tak daleko:

//Open a URL Stream 
Response resultImageResponse = Jsoup.connect(imageLocation).cookies(cookies).ignoreContentType(true).execute(); 

// output here 
OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(new java.io.File(outputFolder + name)); 
//BufferedWriter out = new BufferedWriter(new FileWriter(outputFolder + name)); 
out.write(resultImageResponse.body());   // resultImageResponse.body() is where the image's contents are. 
out.close(); 

Answer 1

nawet nie dokończyć pisanie na pytanie zanim znalazłem odpowiedź poprzez JSoup oraz małe eksperymenty.

//Open a URL Stream 
Response resultImageResponse = Jsoup.connect(imageLocation).cookies(cookies) 
             .ignoreContentType(true).execute(); 

// output here 
FileOutputStream out = (new FileOutputStream(new java.io.File(outputFolder + name))); 
out.write(resultImageResponse.bodyAsBytes()); // resultImageResponse.body() is where the image's contents are. 
out.close(); 

Answer 2

prostu można z nich korzystać METODY

public static String storeImageIntoFS(String imageUrl, String fileName, String relativePath) { 
    String imagePath = null; 
    try { 
     byte[] bytes = Jsoup.connect(imageUrl).ignoreContentType(true).execute().bodyAsBytes(); 
     ByteBuffer buffer = ByteBuffer.wrap(bytes); 
     String rootTargetDirectory = IMAGE_HOME + "/"+relativePath; 
     imagePath = rootTargetDirectory + "/"+fileName; 
     saveByteBufferImage(buffer, rootTargetDirectory, fileName); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    return imagePath; 
} 

public static void saveByteBufferImage(ByteBuffer imageDataBytes, String rootTargetDirectory, String savedFileName) { 
    String uploadInputFile = rootTargetDirectory + "/"+savedFileName; 

    File rootTargetDir = new File(rootTargetDirectory); 
    if (!rootTargetDir.exists()) { 
     boolean created = rootTargetDir.mkdirs(); 
     if (!created) { 
      System.out.println("Error while creating directory for location- "+rootTargetDirectory); 
     } 
    } 
    String[] fileNameParts = savedFileName.split("\\."); 
    String format = fileNameParts[fileNameParts.length-1]; 

    File file = new File(uploadInputFile); 
    BufferedImage bufferedImage; 

    InputStream in = new ByteArrayInputStream(imageDataBytes.array()); 
    try { 
     bufferedImage = ImageIO.read(in); 
     ImageIO.write(bufferedImage, format, file); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

}
