Regular expression for JSON code - regex

I'm trying to extract the access_token value.
anyone know how to extract this.
{"access_token":"c170f85d-9371-31c3-a4fa-1f0865ef28da","refresh_token":"6312ab1a-e257-38e9-aab1-8f8071dfd643","scope":"openid","id_token":"eyJ4NXQiOiJOVEF4Wm1NeE5ETXlaRGczTVRVMVpHTTBNekV6T0RKaFpXSTRORE5sWkRVMU9HRmtOakZpTVEiLCJraWQiOiJOVEF4Wm1NeE5ETXlaRGczTVRVMVpHTTBNekV6T0RKaFpXSTRORE5sWkRVMU9HRmtOakZpTVEiLCJhbGciOiJSUzI1NiJ9.eyJhdF9oYXNoIjoibTFGZUk4ZFJFbDV6azZoTFd2VUxBUSIsImNfaGFzaCI6IkRGbVY3RUt4dzlhck4xNFhDOUxQT1EiLCJzdWIiOiJzb2wxdXNlcjYwIiwiYXVkIjpbInRlc3RtYW5lZXNoYWNvZGUwMDAwMDAxMjMwMDAwIl0sImF6cCI6InRlc3RtYW5lZXNoYWNvZGUwMDAwMDAxMjMwMDAwIiwiYW1yIjpbIkJhc2ljQXV0aGVudGljYXRvciJdLCJpc3MiOiJodHRwczpcL1wvbG9jYWxob3N0Ojk0NDNcL29hdXRoMlwvdG9rZW4iLCJleHAiOjE1MzM3Mjk4MjYsImlhdCI6MTUzMzcyNjIyNiwic2lkIjoiZmE0NDNjZTMtNTI0MS00N2ZkLWIxYzYtMDkxNTU1ODNmZDcwIn0.J6ymae3s4UOvNRiJIL_kdni4HRgUoIHf4speGduQjGd_ny_3ow0MjxHW51wxJfAWpSw9a8cMfc5DkI0lgQmPoWUeNlQ1-loNOGPCMREE4PfJPG312psjxecIjU0j7fr8ma-wAkPKMicSK1VrrbURgU9XdVjve3iVOyAW7ypuGuIgOqwulQdYMldTVBrixWjQvjmygezV30V48OAY8oNIrp6nLWzBUV9w9Zb7_ASblLSezMceIecHMl-0EBAnMYvqgxtbk8aB* Connection #0 to host localhost left intact tLOsz3bqAonEMk3EvnWrQ7GsL2Mrtc_Wo2n7bfv3fkdjkeeb8fuVqUuC4nG-u2In9hdck8HOXoojZQ","token_type":"Bearer","expires_in":2881}
I need to get c170f85d-9371-31c3-a4fa-1f0865ef28da only from above response.
How can I get it using a regex?

Add a JSON extractor as a child to the request where you are getting above response
use $..access_token as JSON path expression.
Match no 1
give name to variable
TO access the variable you can use ${variablename}

JMeter - How to extract query string and request headers?

I am working on log-in scenario for Jmeter. Once I logged-in, I am redirected to the below request:
https://analogb2c.b2clogin.com/analogb2c.onmicrosoft.com/B2C_1A_ADI_SignUpOrSignInWithKmsi/SelfAsserted?tx=StateProperties=eyJUSUQiOiJlOWRiNTU1Zi05N2ZmLTRmOTYtOGQwMC0yOTc2MGNlYmE4ZDYifQ&p=B2C_1A_ADI_SignUpOrSignInWithKmsi
How do I extract the Query String Parameters "tx" and "p" and "X-CSRF-TOKEN" that is in the request headers? What is the regular expression to get the values? I will use the value to the next succeding request. Thanks
Query String Parameters
For the tx it would be something like:
tx=(.+?)&
For the X-CSRF-TOKEN it would be something like:
X-CSRF-TOKEN:\s*(.*)
If you have problems with JMeter Regular Expressions - you can consider switching to the Boundary Extractor, it basically extracts everything between left and right boundaries, doesn't require any domain knowledge and works much faster.

Extract location from response header in Jmeter

From the below string
https://ABC.somewebsitename.com/Account/AutoLogOn?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIxMDEyMzk3ODMiLCJ0YXJnZXRDb3VudHJ5Q29kZSI6IkpQIiwiZXhwIjoiMTU3OTUxMjc4MiJ9.QhfDKvZXSrqTjGYsBaZUd6ErbYoOJUdta0efws2SI-nv0VYqUvByHvoKbWVGvd89RmOi-KV33CDHU8NE_Pl0NA
I want to extract the value after token and send it as a parameter in next request for that I used Regular Expression extractor as below
But in the next request parameter, I am not able to get those values
Am I missing something, can you help me on this?
Note: I have followed the link Extract Location from Response Header with JMeter but still no use.
Your regular expression is missing capturing group, I believe you should amend it like:
https.+token=(.*)
Demo:
However if you just need to extract the token and append it to the next request it is easier to consider Using the HTTP URL Re-writing Modifier
Regular expression should be token=(.+?)$
Also set the Field to Check to URL in the Regular Expression Extractor element.
I did some trial and error, and got the answer,
In the Regular Expression Extractor, used as
Regular Expression: Location: .+\/AutoLogOn\?token=(.*?)\n

JMeter: How to write regular expression extractor for this request URL

(//test-clinicalpl.hee.heaelth.nz/nzty/?encryptedRequest=B3616B90E8CD11B90E99022FE7998834453B92493671C1AF3DB24346493F5364579EF1E9A9FED64B25E1593A3EF768A887B89E5A5A73EDD7BD6D88A1C4ED2D0E994820BEE64B410113603687174086C8B0FEEFF051774184&mac=6252A91F473FD4F4C66E17A7928AFAA48E0E612A&expiry=0000016954D411EC
encryptedRequest, mac and expiry are the dynamic values changes everytime
I wrote this as there regular expression extractor as below:
encryptedRequest= (.*?)& mac=(.*?)& expiry=(.*?)
Right click on the request and add post processor: Regular Expression Extractor.
Use this RegExp
encryptedRequest=(.*)&mac=(.*)&expiry=(.*)
Specify Variable name, myEncryptedRequest for example
Set Template - $1$ for the first matching ($2$ - for the second mac, etc).
Use this values in next requests as ${myEncryptedRequest}
You may add more Regula Expression Extractors to parse another values.
Please refer to JMeter component reference for more details and Guide how to extract and re-use as variable

Regular Expression for retrieving File Extension in HTTP url

I am working on the ELK stack and as part of Logstash data transformation i am transforming data in Apache access logs.
One of the metric needed is to get a stat on different content types (aspx, php, gif, etc.).
From the log file I am trying to retrieve request url and then deduce the file type, for ex /c/dataservices/online.jsp?callBack is the request and I would get .aspx using the regular expression
\.\w{3,4}.
My regular expression wont work for request say /etc/designs/design/libs.min.1253.css this is returning me .min as the extension.
I am trying to get the last extension but it is not working. Please do suggest other approaches.
You need to anchor the match to the end of the string or the beginning of a query param ?. Try:
\.\w{3,4}($|\?)
Play with it here: https://regex101.com/r/iV3iM1/1
You're going to need a much fancier Regex.
Try this one.
([/.\w]+)([.][\w]+)([?][\w./=]+)?
This uses three capture groups. The first ([/.\w]+) matches your path up to the last .
The second ([.][\w]+) matches the final extension, and you can use the capture group to read it out.
The third ([?][\w./=]+)? matches the query string, which is optional.

Extracting json data from Jmeter http request response

I can't find a way to extract array from a json response in Jmeter http request. All other fields i'm able to extract. However something like the following i cannot seem to extract. is there any way i can extract this from response in Jmeter http request? In the following i need to extract [1,2,3] and save it in a variable.
"days":[1,2,3]
"sectionIds":[abc,def,ghi]
something like the folliwing i can just extract using "subscriptionId":"(.+?)" in the jmeter regular expression extractor
"subscriptionId":"abcd"
time value can be extracted using this "time":(\d+)
"time": 120
I guess you have problem with square braces not being quotted. Try:
"days":(\[.+?\])
or if you want to match numbers inside something like:
"days":(\[(\d+,?)+\])
I don't think that Regex way is the best option to deal with JSON data.
There is a plugin called JSON Path Extractor which provides functionality alike to JMeter Embedded XPATH Extractor but targeting JSON.
