I want to call an API using shellscript but I m not able to put header properly...whats going wrong in my script... thanks in advance.

shell script : 

#!/bin/bash
curl -H "Authorization: Basic ABCDEFGHIJKLMNOPQRSTUVWXYZ" -H "Content-Type: application/xml" -X POST -i -d "" -o session.xml  http://a.b.c.d:xxxx/api/auth/

session=`grep -i x-rest session.xml | head -1 | cut -d ' ' -f 2`

echo $session

set -xxx
curl -H "X-RestSvcSessionId: ${session}" -X GET  "http://a.b.c.d:xxxx/api/jobs"

output:

<pre>

"session" contains a carriage return, which ruins your curl request. Replace the grep/head/cut in backticks by:

session=$(awk '/^X-RestSvcSessionId/ {print $2}' session.xml)

and use the following curl parameter:

--cookie "X-RestSvcSessionId=$session"

  • not working :-( – Tiger Feb 27 '18 at 13:48
  • Can you publish your session.xml somewhere? – Gerard H. Pille Feb 27 '18 at 14:01
  • HTTP/1.1 201 CREATED Transfer-Encoding: chunked Content-Type: application/xml; charset=utf-8 Location: http://W.X.Y.Z:xxxx/api/sessionMngr/abcd-efgh-ijkl-mnop-qrstuvw Server: Microsoft-HTTPAPI/2.0 X-RestSvcSessionId: NWJlYjVlZWItMWFmOS00YjU0LWJkOWYtNDA5MTA4NjEwODhi Set-Cookie: X-RestSvcSessionId=NWJlYjVlZWItMWFmOS00YjU0LWJkOWYtNDA5MTA4NjEwODhi; Path=/api; Date: Tue, 27 Feb 2018 13:47:46 GMT – Tiger Feb 27 '18 at 14:05
  • Put it at least in your question, that some of the formatting remains. But this wiill still remove any special characters that you don't see. – Gerard H. Pille Feb 27 '18 at 14:08
  • My mistake, bash starts a subshell for the pipe, so the variable session is lost after the read. – Gerard H. Pille Feb 27 '18 at 14:14

The problem is if you SET variable by curl, grep, head or tail ++ then you will have a NEW Line in the END of your variable.

To remove the NEW Line set your last curl with $session like:

curl -H "X-RestSvcSessionId: ${session//[$'\t\r\n ']}" -X GET  "http://a.b.c.d:xxxx/api/jobs"

This will remove the new line and tab (if any).

I had same error: check here
