How to HTTP POST pure binary data to external system?

[Andy-L]

Hi, I'd like to send an attachment from ServiceNow to an external system - ZenDesk. This first requires the file to be uploaded using HTTP POST.

I was using the RestMessageV2 api - it works for text but not for binary. I guess the binary data is being corrupted by the Java String due to invalid UTF.

The curl example is below (and here ). It uses a pure binary format (application/binary), and specifically does not interpret base64 , MIME etc.

curl "https://{subdomain}.zendesk.com/api/v2/uploads.json?filename=myfile.dat" \

  -v -u {email_address}:{password} \

  -H "Content-Type: application/binary" \

  --data-binary @file.dat -X POST

(Out of curiosity I did try to POST a mutlpart/form-data to ZenDesk using Curl but ZenDesk just interpreted the entire message as the file including control codes)

I've looked briefly at the httpClient classes:

•     Packages.org.apache.commons.httpclient.HttpClient();
•     GlideHTTPClient();

But I've seen comments that the latter only exposes string functions.

I've seen some info on saveResponseBodyAsAttachment() I guess I'm looking for something like sendAttachmentAsRequestBody()

or ideally just a way to do a simple pure binary HTTP post.

Any ideas ?

I've also looked from the ZenDesk end, to see if it can accept Base64/Mime but there does not seem to be any options there (No SOAP API etc)

Hi Andrew,

Have you checked this?

GlideSysAttachmentInputStream

Hi Srini, yes I've seen that. That is for   binary on the response,, I want to send binary on the request.

Hi Andrew,

RESTMessageV2 - setRequestBodyFromAttachment(String attachmentSysId)

Hi Looks promising but according to   this ( setRequestBodyFromAttachment - How does it work?   ) it sends Base64 ? Can you confirm? I need a pure binary post...
