After long hours trying figure out how perform token from app user I have problem with JWT. 

I try with differents libs the only that works https://github.com/cghil/cmd-line-tok-generator, but on my server don`t run node, so I only can use this localhost tests

 

I`m using CURL and $.post() both return the same error i don`t know what to do.

I set my timezone to date_default_timezone_set('UTC') sincronize my timezone with http://www.unixtimestamp.com/

 

but continuous receive same error: {"error":"invalid_grant","error_description":"Please check the 'exp' claim."}

 

I pass "exp" with value integer timestamp generate with strtotime();

  Hi lukasfigueiredo,

   

  Are you setting exp to the exact time returned by strtotime()? If so, that might be the issue. You'll want to set exp to the current timestamp, plus an additional 1-60 seconds in the future (the grant is valid for up to 60 seconds). For instance, here's how I'm setting it in Node / JS, adding an additional 45 seconds in the future.

   

  exp: Math.floor(Date.now() / 1000) + 45

  Hopefully that helps,

  Jon
