For cleaner output formatting, the JSON output can be passed to Python and the module json.tool (output
limited for brevity):
Command:
curl "https://<iDRAC IP>/redfish/v1/" -k | python -m json.tool
Response:
{
"@odata.context": "/redfish/v1/$metadata#ServiceRoot",
"@odata.id": "/redfish/v1",
"@odata.type": "#ServiceRoot.1.0.0.ServiceRoot",
"AccountService": {

},

3.2.1 Using cURL with authentication
As discussed above, Redfish supports Basic and Session based authentication. Here are the cURL
commands used for authentication operations:
Basic authentication: Drilling down further into the Redfish API will require authentication. This can be done
using “-u username:password” on the cURL command line:
curl "https://<iDRAC IP>/redfish/v1/Chassis" -k -u root:calvin
This authenticates the single operation using the provided credentials.
Session based authentication: This requires a two stage process, creating a session called Login and
deleting session called Logout. For login, run the following command in verbose mode by appending option –
v; this will output the X-Auth-Token value for use in the subsequent commands:
