how to put variable in CURL header using shell script?

shell-script shell curl

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

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:

Can you publish your session.xml somewhere?

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.

My mistake, bash starts a subshell for the pipe, so the variable session is lost after the read.
