Unable to extract a simple data from response using jmeter - ajax

I have got a simple ajax response and I am trying to extract the value of orderId and orderItemId from the below response. I tried json path post processor as well as regular expression extractor.
I gave like this in the post processor
"orderId": ["(.+?)"]
template-$1$
Match No-1, in the Regular Expression. But it is not extracting the value.
/*
{"orderId": ["1389104"],"orderItemId": ["7900094"],
}
*/
Any idea why? I have extracted more complicated values using regex. This one is a bit strange.Is there any difference if it is an ajax response?


Use this Regular Expression: "orderId": \["(.+?)"]


You were close, but [ is a special character is regex, you need to escape it with \, use Regular Expression Extractor
Regular Expression: orderId": \["(\d+)
Template $1$
Match No 1

Hit to retrieve `state` and `nonce` from the response using regular expression in JMeter

want to retrieve nonce and state using the regex extractor.
I have tried with .*state=(.*).* but not working specially with the escape character \u0026, any clue how to retrieve ?

How about state=(.+?)\\u0026 ?
Meta characters need to be escaped with another backslash
Also if you have hard time coming up with a proper regular expression you can always use Boundary Extractor instead, it's much easier to use and it works faster.

Fetch the value from the response data in Jmeter

Here is my response data,
{"system":false,"redirect":{"href":"\/\/localhost-933824.auth.org\/dashboard","data-loader":"fullscreen"},"name":false,"url":"login\/auth\/localhost","container":"#pyModule","scope":null,"infinite":false,"action":{"method":"update","target":"container"},"csrf":{"name":"csrf_token","value":"e18a9gbd853bda5c317cv48a3426y28e"}}
Want to fetch 933824 value from the response, how to do it in any extractor like regex or json in Jmeter ? I tried with [^?]+(?:\?localhost-([^&]+).*)? and /\?localhost-([a-z0-9\-]+)\&?/i but not working.

You're making the things too complicated, there is \d meta character which stands for the "digit" and if you add a + sign which stands for "repetition" it will match any number of digits.
So you can simplify your regular expression to something like:
localhost-(\d+).auth.org
Also be aware that there is even simpler way: using Boundary Extractor where you don't have to bother about coming up with a proper regular expression, you just need to provide "left" and "right" boundaries and it will extract everything in-between:
Moreover this approach consumes less resources and acts much faster. More information: The Boundary Extractor vs. the Regular Expression Extractor in JMeter

Please try below, add a regular expression extractor and provide the below expression
localhost-([^&]*).auth.org

Extract Specific Value from string using regex extractor in JMETER

I need to be able to extract from an access token formatted like:"access_token\":\"71da3526-3592-49fb-9810-3103aed257fe\".
I need to be able to get just 71da3526-3592-49fb-9810-3103aed257fe when using regEx Extractor.

You need to escape each occurrence of \ symbol in order to get your regex to work, it would be something like:
"access_token\\":\\"(.+?)\\"

Not able to read session id from response in jmeter

i want to fetch "chat_session_id": 8216, from response data and apply regular expression extractor
"chat_session_id": (.+?)
but it only fetches 8 instead of 8216

You did correctly, the mistake is you need to add comma to your regular expression
Actual value: "chat_session_id": 8216,
Regx: "chat_session_id": (.+?),

Try amending your regular expression to look like:
"chat_session_id": (\d+)
This one will match any number following the chat_session_id: so it should work as it evidenced by View Results Tree listener output:
In general, given you are getting the response in JSON format it would make more sense to use JSON Extractor which is designed for working with JSON data type. The relevant JSON Path Expression would be as simple as:
$..chat_session_id

Jmeter Extracting response body

my web sampler request has a reponse message of
[Message 1]
{"event":"pusher:connection_established","data":"{\"socket_id\":\"177828.486549\",\"activity_timeout\":120}"}
How I can extract 177828.486549?
Many thanks.

Actually regular expression for this is very simple, you only need to remember that backslash - \ is a special "escape" character hence it needs to be escaped with another backslash
Add Regular Expression Extractor as a child of the element which returns above message
Configure it as follows:
Reference Name: anything making sense, i.e. socket_id
Regular Expression: "socket_id\\":\\"(.+?)\\"
Template: $1$
Refer extracted value as ${socket_id} where required
Demo (you can test your regular expressions right in View Results Tree listener:
