How to download image from DAM using AEM HTTP API?

[jamesc25111500]

I am trying to download image thumb nails or original from DAM and show on another web page hosted by another server. Here is my Java servlet:

	public void downloadImage(String img_name) throws IOException 
	{
		String asset_api = "https://dam.company.com/api/assets/products/" + img_name + "/renditions/cq5dam.thumbnail.319.319.png";
		try {
			URL url = new URL(asset_api);
			HttpURLConnection conn = (HttpURLConnection) url.openConnection();
			conn.setRequestProperty("Content-Type", "application/octet-stream");
			conn.setRequestProperty("Authorization", "Basic xxxxxxxxx");
			conn.setDoOutput(true);
 
 			System.out.println("resp=" + conn.getResponseCode() + " - " + conn.getResponseMessage());
 			......
		} catch (Exception ex) {
			ex.printStackTrace();
		}
	}

But it got error: HTTP/1.1 404 Not Found. I can opened asset_api on the browser directly and it absolutely exists and works fine. Do I need to set permission for running AEM HTTP API for account used in this servlet or need some other settings?

Thanks,

James

@jamesc25111500 Assets HTTP API are to perform CRUD operations. The above URL will let you read or view the asset but not download it. However, there is a Download Config which essentially enables the Download Servlet and lets you download the Asset via HTTP call.

Enable Asset Download Servlet: https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/assets/manage/do...

curl command to download:https://experienceleague.adobe.com/en/docs/experience-cloud-kcs/kbarticles/ka-21528

Let me know, if this helps.

Krati,

I found out it's permission issue for the account used in above servlet. When I checked Read ACL for this account in account permission setting page, the above servlet works fine. 

Thank you for your time.
