In need to pass a data from a response to the subsequent request. Something goes wrong and the default variable value appears in the request.
First request returns the JSON in response body which looks like this:
{"issued_at":"2016-01-14T12:41:01.000Z","expires":"2016-01-14T12:46:01.000Z","id":"j6M ... MTA=="}
I extract the value of the id attribute using the Regular Expression Extractor:
Then I pass the token variable to the subsequent request parameter:
But the request is created with the default value of the variable:
There is a JSON Path Extractor designed to deal with JSON content type, I believe it would be easier to use it.
The relevant JSON Path query will be as simple as $..id
See Using the XPath Extractor in JMeter (scroll down to "Parsing JSON") for comprehensive information on plugin installation and usage and JSONPath - XPath for JSON for JSONPath language reference and examples.
In regards to your Regular Expression Extractor configuration:
remove 1 from Match No.
Provide $1$ as Template
If you look at the Regular Expression Extractor documentation, the field Template is required. I suggest you to use value $1$ and try again.
The problem was resolved by setting the "Field to check" radio button to "Body" at the "Regular Expression Extractor" dialog and by setting the Template field value to $1$.
Thanks to alphamikevictor and Dmitri T for help!
You should use ${token_g1} to get the value of the first group of the regex match (the value you're looking for).

I have JSON responce
{
"sessionName":"eL7tYgxhYh",
"imageSrc":"/Common/CaptchaImage/**eL7tYgxhYh**?t=636573960197174426"
}
How I can get a random value string "eL7tYgxhYh" in href by JSON Path Extractor with JMeter?
You cannot achieve this using JSON Extractor as it can only deal with JSON Objects, i.e. you can easily get full value of the imageSrc attribute, but not more.
I would recommend switching to Boundary Extractor instead, the relevant configuration would be something like:
Name of created variable: anything meaningful, i.e. href
Left Boundary: CaptchaImage/
Right Boundary: ?
That's it, the "interesting" value should be now extracted and you should be able to refer it as ${href} where required
Demo:

JSON format is in key-value pair so you just need to mention the key for which you need to extract the value. As in your case, you can use following JSON path expression for fetching the text mentioned by you:
$.sessionName
You can also use regular expression extractor which is another most important element of JMeter to extract the dynamic variables. Please refer to below blog of RedLine13 for more information on Regular Expressions:
https://www.redline13.com/blog/2016/01/jmeter-extract-and-re-use-as-variable/
Let me know if you have any further question
Above figure shows how to access access_token response of json and store it in access_token variable. In your case need to replace below.
JSONPath Expression use
$..sessionName
Destination variable Name
SessionName

To get required string from result string you can use BeanShell Assertion to split the string.

To Fetch jmeter Elements
I've the following URL
https://x.x.x.x/x/continue?processId=1234567&formAction=register
I need to extract the proccessId to use in the following request, but in JMeter with XPATH extractor value
//*[#id="signupForm"]
I can't recover the value, is there any option to solve it?
Easier to use Regular Expression Extractor for fetching value from URL
Add as a Post Processor of request Regular Expression Extractor with values:
Regular Expression: `processId=(\d+)&formAction=register`
Template `$1$` (indicate first group)
Match No. `1` ( fetch the first number)
Reference Name: `yourVariableName`
and then use ${yourVariableName} in your next request(s).
Note: If you are extracting from Request's URL you need to choose URL in Field to Check radio buttons.
In my application while executing the first request one unique key is generated which key is required for Next all the request. let me how to automate such scenario in Jmeter.
The process should look as follows:
Add Post Processor to the first request
Configure it to extract the required value and store it into a JMeter Variable
Use JMeter Variable from step 2 in your next request.
Depending on response data type you have the following choices:
Regular Expression Extractor - for text
CSS/JQuery Extractor - for HTML
XPath Extractor - for XML and XHTML
JSON Path Extractor - for JSON
It is also possible to extract data from files i.e. if response is in PDF format, but it's a little bit tricky
Example configuration to store the whole response:
Reference Name: any suitable variable name, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
You can refer the extracted value as ${response} where required. You can also amend the regular expression to extract response part instead of the whole response. JMeter uses Perl5-compatible regular expressions, see Regular Expressions User Manual Chapter for details
You can use regular expression extractor to extract the key from the response of your first request and use the extracted key for subsequent requests. To achieve this:
Right click on the first request and add post processor: Regular Expression Extractor.
Create your regular expression and provide values in other required fields. Please refer to JMeter component reference http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
Extracted value will be saved in the variable given as reference name
Use this variable in subsequent requests
Here is an example test plan with results.
This is the response data from which i need to extract token value
{
"token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0IjoibXljb21wYW55IiwiZCI6ImhrZy5maXJlYmV0LmRldi5zdXBwb3J0LmNvbSIsInBybSI6WyJsb2c6KiIsInNlc3Npb246Y29ubmVjdCIsInNlc3Npb246dXBsb2FkRmlsZToxMjUyMyIsInNlc3Npb246ZGV2aWNlSW5mbyxsb2dhY3Rpdml0eWV2ZW50LGRldmljZWNhcGFiaWxpdHk6MTM1MTEiXSwianRpIjoiMGVmNmU5OGYtZjQ0My00NmEzLTkxMmMtMDNiNmMyZDFjNzU1IiwiYXBwIjoiVGVzdGFwcCIsInZlciI6IjEiLCJwbHQiOiJBbmRyb2lkIiwiaWF0IjoxNDMyNjE4MDY3LCJhdWQiOiJhcHAiLCJleHAiOjE0MzI2MjUyNjcsImlzcyI6IlN1cHBvcnQuY29tIn0.qkgSrZFoc2MR8xQN0boRd85PcmD1R0xkQjVzKXNv2Uk",

"relay_config": "tdssd:443",
"symmetric_key": "dssdFx0=",
"workflow_version_id": 10s008,
"unique_connection_id": "fsdsd"
}
Currently I am using regular expression extractor
token: "(.*?)"
Just add closing quotation mark to your regular expression as
token": "(.*?)"
and use $1$ as Template
Another option is using JSON Path Extractor which comes with JMeter Plugins which is more handy to extract stuff from JSON responses. In that case use the following JSON Path query:
$..token
See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for more information on the JSON Path language and few useful examples.
Extracting token value from the response
So here I you used as User id so please change this in token so and use post processor regular expression it will definitely work
Use
"token":"(.+?)"
in the JSON Path Extractor.
In regular expression extractor use regular expression as token": "([^"]+)" and template $1$.
I hope this will help you.
How do i write the regular expression for the json response.
My json response is "publisher":"/api/web/publishers/194".
From this response i want to get only the numeric value i.e 194. Some one pls help in getting it?
If "194" is the only integer in your response than your regex can be limited to just '(\d+)`
If you response contains more digits, you'll need to be more specific, like
"publisher":"/api/web/publishers/(\d+)"
So something like:
Reference Name: publisher
Regular Expression: "publisher":"/api/web/publishers/(\d+)"
Template: $1$
Will extract "194" and store it in "publisher" JMeter Variable. You'll be able to refer to it as ${publisher} later in Thread Group.
Going forward if you'll need to extract something from more complex JSON structures I'd recommend consider using JSON Path Extractor available via JMeter Plugins - the extractor lives in "Extras with Libs Set" package.
