upload blob/byte[]

Ana_Paula_Lopes — Fri, 24 Mar 2017 19:09:23 GMT

Hello everyone, Is it possible to upload a file by just blob or byte [] instead of the file itself ??? See the example below:

private Document exportNuxeo() throws IOException {
		
		
		Document doc = new Document("file", "File");
		doc.set("dc:title", "Documento 1");

		doc = nuxeoClient.repository().createDocumentByPath("/camara.leg/workspaces/", doc);

		Document docCriado = nuxeoClient.repository().fetchDocumentByPath("/camara.leg/workspaces/file");

		Blob fileBlob = new Blob(new File("c:\\Desenvolvimento\\doc-nuxeo\\teste.pdf"));

		nuxeoClient.automation().newRequest("Blob.AttachOnDocument").param("document", docCriado).input(fileBlob)
				.execute();

		return doc;
	}

Blob fileBlob = new Blob(new File("c:\\Desenvolvimento\\doc-nuxeo\\teste.pdf"));

Instead of being the File object being, I use a Blob or byte []

Because I will need to migrate multiple files from the sql server database to nuxeo....

Hello,

This is currently not possible with our java client. I created https://jira.nuxeo.com/browse/JAVACLIENT-125 to add this feature to client. But it may take times to be done. You can create a PR with the feature if you want, have a look at https://doc.nuxeo.com/nxdoc/contributing-to-nuxeo/ before.

Unless, I'm afraid you need to serialize the byte[] to a file in order to upload it. Something like this should work:

FileUtils.writeByteArrayToFile(new File("pathname"), myByteArray)

FileUtils is a class from Apache Common IO, used by the client.

I need to migrate some files (+/- one million and a half) that are in SQL Server to nuxeo ...

I would have these files in blob or byte []

The only way to do this is to write the blob or byte[] to a temporary file and then upload this file by using blob object from nuxeo-java-client.

Do you have any examples using this getByteArray() ???? and could you share it for me?

This isn't nuxeo-related, it's just pure java code. Something like this should work
