Sending json file through Http Post curl - php

Question

I have been working with Jenkins, and now Im stuck when I try to make an HTTP Post using curl, I am sending a json file, to a file in my page who is waiting for it, and then do some functions, the code I am using is the following:
curl -X POST -k -i -H "Accept: application/json" -w "%{body}" -w "%{http_code}" -d "#/var/lib/jenkins/workspace/myFolder/session.json" http://mypage.com/myFolder/newfile.php
But apparently Im not sending correctly the data of the file, the newfile.php has something like this:
echo $_REQUEST['sessionId'];
But always get an error when I try to echo the index sessionId, I mean my file "newfile.php" is not getting anything from my jenkins curl, can you help me out?
Thanks in advance!!

Answer 1

The JSON that you send is in the request body. The keys/values will not be available in the $_REQUEST array, hence why you are getting the error. You will need to access the request body in order to get the sessionId property.
$requestBody = file_get_contents('php://input');
$session = json_decode($requestBody);
$sesionId = $session["sessionId"];
echo "Session ID: $sessionId";
The file_get_contents('php://input') returns the body of the POST request.
Make sure to also add the appropriate Content-Type header to your post request:
curl -X POST -k -i -H "Accept: application/json" -H "Content-Type: application/json" -w "%{body}" -w "%{http_code}" -d "#/var/lib/jenkins/workspace/myFolder/session.json" http://mypage.com/myFolder/newfile.php`
