The same protocol is used for both, with the server primarily being a relay with store-and-forward capabilities.

The raw protocol also supports a 'paranoid mode' where a second modulepassword is used in the apps and vehicle module to double-encrypt the data so that even the server cannot decode it.<br><br></li><li>There is an experimental HTTP protocol (API) that runs on the server and is used to read the vehicle data and communicate with the vehicle. We want to use this as the basis for future apps. With this api, the data returned is in JSON format and is structured as human/machine readable (for example 'SOC', rather than 1st field in the 'D' message).<br><br></li><li>The HTTP API currently uses OVMS username+password for authentication, and returns an authentication cookie. That is fine for experimental use, but suffers when trying to get third parties involved (as the user would need to give their OVMS username + password to the third party for storage). We would like to migrate that to an OAUTH style scheme.<br><br></li><li>It seems sensible to use a variant/extension of the HTTP API for this work on charge event distribution.</li></ol></div><div><br></div><div>The OVMS <a href="http://www.openvehicles.com/">www.openvehicles.com</a> site is in PHP (Drupal) and the OVMS server itself is in perl (AnyEvent and AnyEvent::HTTP based).</div><div><br></div><div>My issue is (a) time, and (b) lack of experience with OAUTH. We would presumably need an OAUTH server (either within the OVMS server or hosted by <a href="http://www.openvehicles.com/">www.openvehicles.com</a>), and an OAUTH capability within the HTTP API on the OVMS server. Quite frankly, I am not sure where to start with this. I've read the background documents, and have an understanding of what is required, but it is very hard to find implementation examples that make sense for what we are doing, in Drupal/PHP or Perl.</div><div><br></div><div>Regards, Mark.</div><div><br><div><div>On 12 Jun, 2014, at 12:58 pm, Christopher Cook <<a href="mailto:christopher.cook@webprofusion.com">christopher.cook@webprofusion.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Yes, sounds like it to me.

Not really my bag but I'm sure there are plenty of oauth modules/libraries for you to choose from. Assuming you need OAuth 1.

My own personal preference is just to provide an api to either PUSH or PULL the data, and the reason for that is I don’t want to be extending the server code to support ten different third-party APIs. That said, I did suggest a PUSH option in the original RFQ, and the thinking behind that is we can format a URL+formdata with parameter-substitution (based on server.conf settings for a particular provider - no code) and just fire it off. I see no problem with a single API key for OVMS to submit to such an external service. For ‘user credit’, it would be nice to have an option where the user could enter an optional username+pin for each service, and we can provide it as part of the PUSHed/PULLed data.<br></blockquote></blockquote></blockquote><br>-- <br>*Lee Howard*<br>*Mainpine, Inc.
