OpenBMC REST cheat sheet

This document is intended to provide a set of REST client commands for OpenBMC usage.

Using CURL commands

Notes on authentication:

The original REST server, from the phosphor-rest-server repository, uses authentication handled by the curl cookie jar files. The bmcweb REST server can use the same cookie jar files for read-only REST methods like GET, but requires either an authentication token or the username and password passed in as part of the URL for non-read-only methods.

The phosphor-rest server will no longer be the default REST server after the 2.6 OpenBMC release.

Establish REST connection session

  • Using just the cookie jar files for the phosphor-rest server:

    $ export bmc=xx.xx.xx.xx
$ curl -c cjar -b cjar -k -H "Content-Type: application/json" -X POST https://${bmc}/login -d "{\"data\": [ \"root\", \"0penBmc\" ] }"

  • If passing in the username/password as part of the URL, no unique login call is required. The URL format is:

      <username>:<password>@<hostname>/<path>...

    For example:

    $ export bmc=xx.xx.xx.xx
curl -k -X GET https://root:0penBmc@${bmc}/xyz/openbmc_project/list

  • Token based authentication. There are two slightly different formats, which return the token differently. In either case, the token is then passed in to future REST calls via the 'X-Auth-Token' or 'Authorization' headers.

    1. Get the authentication token from the header that comes back from the login when using the data username/password JSON dictionary and a -i argument to show headers:

      $ export bmc=xx.xx.xx.xx
$ curl -i -k -H "Content-Type: application/json" -X POST https://${bmc}/login -d "{\"data\": [ \"root\", \"0penBmc\" ] }"
  HTTP/1.1 200 OK
  Set-Cookie: XSRF-TOKEN=4bmZdLP7OXgreUbazXN3; Secure
  Set-Cookie: SESSION=vnTdgYnvhTnnbirQizrr; Secure; HttpOnly
  ...

  $ curl -H "X-Auth-Token: vnTdgYnvhTnnbirQizrr" -X POST ...
  $ curl -H "Authorization: Token vnTdgYnvhTnnbirQizrr" -X POST ...

    2. Get the authentication token as part of the response when using a JSON dictionary with 'username' and 'password' keys:

      $ export bmc=xx.xx.xx.xx
$ curl -k -H "Content-Type: application/json" -X POST https://${bmc}/login -d '{"username" :  "root", "password" :  "0penBmc"}'
 {
   "token": "g47HgLLlZWKLwiyuUwJM"
 }

 $ curl -H "X-Auth-Token: g47HgLLlZWKLwiyuUwJM -X POST ...
 $ curl -H "Authorization: Token g47HgLLlZWKLwiyuUwJM -X POST ...

Commands

Note: To keep the syntax below common between the phosphor-rest and bmcweb implementations as described above, this assumes that if bmcweb is used it is using the <username>:<password>@<host> login method as described above:

   export bmc=<username>:<password>@xx.xx.xx.xx
