Groovy Script to store an image file as .jpg from http response body with content type as image/jpeg

[cl509920]

An API GET response returns an image in the body, like this: This is not an attachment.

HTTP/1.1 200 OK

2!!2 ...... and so on.

Postman decodes the image an displays it, it is an animal in this case.

I have to store the response as an image file (.jpg) using a groovy script in soapUI(soapUI is used to test the API)

This is what I've tried in a Groovy Script step, but the image saved is unintelligible malformed.

testRunner.runTestStepByName("GETjpg");
def getImageResponse = new String(testRunner.testCase.testSteps["GET Image"].testRequest.response.responseContent);
byte[] imageInByte;
BufferedImage originalImage = ImageIO.read(new ByteArrayInputStream(getImageResponse.getBytes()));

// convert BufferedImage to byte array
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(originalImage, "jpg", baos);
baos.flush();
imageInByte = baos.toByteArray();
baos.close();

// convert byte array back to BufferedImage
InputStream inRead = new ByteArrayInputStream(imageInByte);
BufferedImage bImageFromConvert = ImageIO.read(inRead);

ImageIO.write(bImageFromConvert, "jpg", new File("C:\\animal.jpg"));

 I guess that what I am doing to save the image in .jpg is not correct. Can someone help?

Attach is the raw response.

Thanks in advance.

This is how I did this. From the Script Assertion of the http GET request. Hope It helps someone. def ins = context.httpResponse.getRawResponseBody(); def isImageSaved = false; InputStream inputStream; FileOutputStream outputStream; if (ins){ try { inputStream = new ByteArrayInputStream(ins); outputStream = new FileOutputStream(new File(context.expand("C:\\animal.jpg"))); int read = 0; byte[] bytes = new byte[1024]; while ((read = inputStream.read(bytes)) != -1) { outputStream.write(bytes, 0, read); } isImageSaved = true; }catch (Exception e){ log.error e; e.printStackTrace(); }finally{ inputStream.close(); outputStream.close(); } } else { log.error "image does not exist..."; } context.testCase.setPropertyValue("isImageSaved", isImageSaved.inspect());
