PROC HTTP POST >> Missing Boundary Header

agno3 — Fri, 21 Apr 2023 18:07:39 GMT

Hi,

I'm trying to post zipped XPT files to a URL using the code below...

But the output file tells me that I am - "Missing boundary header", hence end up with a 400 Bad Request.

This is what I see when I create an output file to capture the response from my PROC. I know my macro variable boundary resolves because I see it from my %PUT in the code.

What am I "missing" here ? Help appreciated.

@ChrisHemedinger - any insight ? Thanks in advance.

filename XptFile "../dataraw/new_zip.zip";

/* Set the authorization header */
%let auth_header = Authorization=Bearer &ACCESS_TOKEN;

/* Set boundary */
%let boundary=%sysfunc(uuidgen());
   %put &boundary.;

/* Make the HTTP PUT request */
filename response temp;
proc http
  method="POST"
  url="&base_uri/repository/container/&containerAID/&version/upload/Raw Data"
  in=XptFile
  out=response;  
  headers 'Authorization'="Bearer &ACCESS_TOKEN"; 
  headers 'Content-Type'="multipart/form-data" 'boundary' = "&boundary.";
  run;

%put &SYS_PROCHTTP_STATUS_CODE.;
%put &SYS_PROCHTTP_STATUS_PHRASE.;

looks like multipart form data isn't yet supported

EDIT: catching up, indeed it is actually supported in 2025
