是否可以将文档发送到DocuSign API而无需将其完全加载到内存中？

Question

All the examples I saw showing how to build up a DocuSign envelope (using Java in my case) use a Base64 encoded String to send the file(s) content.

That means loading the entire file into memory.

Is there a way to send files to the DocuSign API without loading them entirely into memory?

Document document = new Document();
document.setDocumentBase64(docBase64);
...

An excellent question.

Yes. You can send the documents in binary form by sending the API request using the multi-part mime format. The SDKs don't support this currently, so you will also need to hand-roll the JSON. But none of this is very hard.

We have examples for all of our major languages . They are workflow number 10 within each of the eg-03 code example repositories on github.com/docusign

Here is workflow number 10 for Java: EG010ControllerSendBinaryDocs.java

Welcome to SOF.

An alternative to Larry's solution, depending on the use-case, you could create a template in DocuSign and then in your API call just refer to the pre-existing template and fill in the tabs and send it. This way there will be no need to use the base64 code. However, in some cases, when there is no static template this might not work.
