REST Multipart/form-data binary image request body?

[Nick65]

So I have been working on an integration and was curious if anyone has successfully created a multipart/form-data outbound REST request with binary image data in Servicenow? With or without use of mid server. I know the request works because it works fine in Fiddler and Restify. Below is the body I am using, I have been able to post this exact message with a text file so I know the issue is with the binary I am sending. I have also tried base64. Does anyone have any tips or tricks for sending binary image data with Javascript? Any pitfalls or issues you have ran into in the past? Thanks !

--gc0p4Jq0M2Yt08jU534c0p

Content-Disposition: form-data; name="body"

goes with message

--gc0p4Jq0M2Yt08jU534c0p

Content-Disposition: form-data; name="attachment1"; filename="testpic.gif"

Content-Type:image/gif

Content-Transfer-Encoding: binary

${attachment}

Nick,

Have you had any luck with this?

[Nick65]

Uhg no, its been tough. Don't think this is even possible with the mid server because of the parsing that happens, every time I have tried this with a mid server I get xml parsing errors. This has also been hard because I don't know where I can or if its even possible to debug outbound rest messages in ServiceNow. I know that rest debug system property can be added but that seems to be strictly inbound rest messages. Another challenge is I know how to get this to a base64 encoded image but when I send that to Yammer its broken, and I am not sure if Yammer even accepts base64 encoded images. And finally another issue I have is when I tried to use Java Package calls I don't know how to call the one I need to build a multi part request. I know the package name is org.apache.http.entity.mime.MultipartEntityBuilder; but have not had success initializes it. So yea,no luck.

And don't get me wrong its not formatting the multipart body, that works fine with plain/text, its the image/binary territory.

Yes, I finally got this done with a custom .jar file and Javascript probe. I wrote a reply on

I believe you must be the same Jonathan, let me know if you have any questions.
