I’m trying to collect two sets of characters in one token authentication. The intention is that the regex collect the word bearer and the outcome of access_token.

I’m having a hard time uniting both collections.

It is possible to perform both collect in the same regex?

Token below - Image and text.

{
  "token_type": "bearer",
  "refresh_token": "MjUwMDAwMTJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIzNTMxMzI1MDAwMDE2NiIsImlhdCI6MTYxMjUzMjE2NSwibmJmIjoxNjEyNTMyMTY1LCJleHAiOjE2MTI1MzU3NjUsImNsaWVudF9pZCI6Im1vYmlsZUZpcnN0RGF0YSIsInVzZXJfbmFtZSI6IjM1MzEzMjUwMDAwMTY2IiwiaW5zdGl0dXRpb24iOiIwMDAwMDAwMyIsImVzdGFibGleyJ0eXAiOijpbIjg5NDUwNDIzIl0sImRldmljZSI6IlBvc3RtYW4iLCJ0b2tlbl90eXBlIjoicmVmcmVzaCIsIm9yaWdpbl9wb3MiOmZhbHNlfQ.CEwEPwRXNN0OrcYk7rc2FFzPwMGPhOKnjUUfuR97bN7hfmwEMp_dQQ4mLRod4xuv32xlEFLPvmxtiM-9IiA53w",

  "accepted_contract_term": true,
  "is_origin_pos": false
}

Is there a reason not to parse the json, and access the values via get using a programming language?

@Danizavtz, thanks for the reply. It has been suggested to use json, however, according to the Zabbix forum, the web scenarios do not support. This way I’m insisting with the regex.

Following the idea of having the two returns in the same regex, one exit would be this:

/"token_type":.?"(.*?)",|"access_token":.?"(.*?)",/g

Where in Group 1, it returns what is within the first parentheses and in Group 2, the second.

In Javascript, this would be a way:

const zabbix = `{
   "token_type": "bearer",
   "refresh_token": "MjUwMDAwMTJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIzNTMxMzI1MDAwMDE2NiIsImlhdCI6MTYxMjUzMjE2NSwibmJmIjoxNjEyNTMyMTY1LCJleHAiOjE2MTI1MzU3NjUsImNsaWVudF9pZCI6Im1vYmlsZUZpcnN0RGF0YSIsInVzZXJfbmFtZSI6IjM1MzEzMjUwMDAwMTY2IiwiaW5zdGl0dXRpb24iOiIwMDAwMDAwMyIsImVzdGFibGleyJ0eXAiOijpbIjg5NDUwNDIzIl0sImRldmljZSI6IlBvc3RtYW4iLCJ0b2tlbl90eXBlIjoicmVmcmVzaCIsIm9yaWdpbl9wb3MiOmZhbHNlfQ.CEwEPwRXNN0OrcYk7rc2FFzPwMGPhOKnjUUfuR97bN7hfmwEMp_dQQ4mLRod4xuv32xlEFLPvmxtiM-9IiA53w",

   "access_token": "osjjjjsssjJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIzNTMxMzI1MDAwMDE2NiIsImlhdCI6MTYxMjUzMjE2NSwibmJmIjoxNjEyNTMyMTY1LCJleHAiOjE2MTI1MzMwNjUsImNsaWVudF9pZCI6Im1vYmlsZUZpcnN0RGF0YSIsInVzZXJfbmFtZSI6IjM1MzEzMjeyJ0eXAiOiIiwiaW5zdGl0dXRpb24iOiIwMDAwMDAwMyIsImVzdGFibGlzaG1lbnRzIjpbIjg5NDUwNDIzIl0sImRldmljZSI6IlBvc3RtYW4ifQ._gEPrD2KsX1sFUwPmGSL0ZORSDRypwFd3u0Z-YhUowvE3iqDK0I_dpdkf_azCIUqs4JNpmj-zkKtmieRIz6afQ",
   "accepted_contract_term": true,
   "is_origin_pos": false
}`;

const regex = /"token_type":.?"(.*?)",|"access_token":.?"(.*?)",/g;

// Test
const token_type = regex.exec(zabbix)[1];
const access_token = regex.exec(zabbix)[2];

console.log(token_type, access_token);
