i'am using jmeter "Regular Expression Extractor",my response looks as below
[{"#class":"com.test.dto.BoardDTO",
"ReadOnly":false,
"author":"John",
"id":"89BC331D723F",
"isPublic":false
},
{"#class":"com.test.dto.BoardDTO",
"ReadOnly":false,
"author":"Alex",
"id":"FTH7JBDRF567",
"Public":false
}]
I need to extract all IDs of class:"com.test.dto.BoardDTO" in this case "89BC331D723F" and "FTH7JBDRF567"
Any proposition please !
You should use JSON Extractor instead of regular expression extractor
Add a JSON Extractor and fill in the fields as below
JSON path expression: $.[*][?(#.#class == "com.test.dto.BoardDTO")].id
Match Numbers: -1
This will return all IDs where #class value was com.test.dto.BoardDTO. You can validate it using View Results Tree & Debug Sampler combination.

I am getting response as
{
"statusCode": 219,
"body": "{"message": "otp sent to user", "session": "f603ee03-4906-4451-b4e5-b19f0ccf84d0", "otp": "123456"}"
}
I want to get the Session number from this response. Do we have any suggestions
I tried post processors however couldn't as the response is in string
This is really strange response. It looks like valid json but isnt really. You can try with regular expression extractor with this expression to match the UUID:
[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}
If the response really looks exactly how you're posting it - you won't be able to use JSON Extractor because it's not a valid JSON
You can use either Regular Expression Extractor and the regex like:
session"\s?:\s?"(.+?)"
If you want explanation:
\s? - optional whitespace character
() - grouping
. - any character
+ - repetition
? - don't be greedy, stop at first match
Or Boundary Extractor configured like:

I am getting a response in form of serialized json format for an api request as below
{"Data":"{\"orderId\":null,\"Tokens\":{\"Key\":\"abcdefgh123456\",\"Txnid\":\"test_5950\"}","success":true,"Test":"success"}
I want to extract Key value in Jmeter and I have to use into next request. Can someone help me on extracting the value?
Your JSON seems incorrect. The valid JSON should be like:
{
"Data":{
"orderId":null,
"Tokens":{
"Key":"abcdefgh123456",
"Txnid":"test_5950"
},
"success":true,
"Test":"success"
}
}
Add a JSON Extractor to the request from where you want to extract the Key value.
assign a variable name, i.e key
JSON Path Expression will be : .Data.Tokens.Key
use the extracted value as ${key} into the next request.
If your JSON really looks exactly like you posted the most suitable Post-Processor would be Regular Expression Extractor
The relevant regular expression would be something like:
"Key"?\s*:?\s*"(\w+)"
where:
``?\s*` - arbitrary number of whitespaces (just in case)
\w - matches "word" character (alphanumeric plus underscores)
+ - repetition
() - grouping

Response is {"d":"14049,171681785,347225778"} and I want to extract the value 171681785 from response
Can somebody help me how to write regular expression to extract 171681785 from the above response?
Since 14049 can change, i can advise you to use JSON Extractor indeed. After getting the value of d with $.d, you can use this code in JSR223 Post Proccesor to get the value in the middle.
String[] array = vars.get("yourVariableName").split(",");
vars.put("theValueYouWant", array[1]);
Regular expression is fetching 9 values
Need to add all these ticked values with comma separation in next request.How can we do this in J meter
How can we pass multiple values extracted via regular expression to next request in JMeter
Can you please share some snippet of the HTML response, I'd like to help you with the answer. Also, at times, using an XPath expression in an XPath Extractor can be easier to work with.
If the reference name for is set to VALUE, then you can access each of the 9 matched values as VALUE_1, VALUE_2, ...... VALUE_9
Given you configure your Regular Expression Extractor as follows:
Reference Name: arg_name
Regular Expression: `arg_names" value="(.+?)"
Template: $1$
Match No.: -1
You will get JMeter Variables like:
arg_name_1=foo
arg_name_2=bar
arg_name_3=baz
arg_name_matchNr=3
Now you should be able to concatenate the values using the following __groovy() function:
${__groovy(def builder = new StringBuilder(); 1.upto(Integer.parseInt(vars.get("arg_name_matchNr"))) { builder.append(vars.get("arg_name_" + it)).append("\,") }; builder.toString(),)}

The response I get back from a post is just a plain text guid seen here I'd like to pull this guid and use it in a variable for my following Get statement:
post response data
And I've tried a bunch of configurations in my regular expression extractor.
But it just ends up pulling Null when what I want is that guid.
Null
I'm new to jmeter - so thank you in advance for the help.
If you need the whole response use the following Regular Expression Extractor configuration:
Reference Name: response
Regular Expression: (?s)(^.*)
Template: $1$
As per How to Extract Data From Files With JMeter guide:
() = grouping
(?s) = single line modifier
^ = line start
. = wild-card character
* = repetition
So it will return the whole response.
