Question

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> % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 5475 0 5475 0 0 43457 0 --:--:-- --:--:-- --:--:-- 43800 OGIyMDUxYTctNjMzNC00MjhjLWJiOTEtZjQ2YmMwZGY1NmY3 -X GET http://a.b.c.d:xxxx/api/jobsjMzNC00MjhjLWJiOTEtZjQ2YmMwZGY1NmY3 </pre> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd"> <HTML><HEAD><TITLE>Bad Request</TITLE> <META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD> <BODY><h2>Bad Request</h2> <hr><p>HTTP Error 400.

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

"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"

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.
