I'm testing some methods like sending a message, checking message status .. etc using Jemeter. To execute these methods I need a bearer / access token. I was able to generate a token, But I cannot figure out how to get that value stored in a variable and use in other post methods.
Can somebody help me with this?Image of my tree
Use the Regular Expression Extractor:
http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
set reference: token
use regular expression: access_token":"([^"]+)"
Use JSON Extractor (it is available since JMeter 3.0), the relevant JSON Path query would be as simple as $.access_token
Demo:
See Jayway JsonPath for more information on JSON Path language.

In my JMeter script I have a request which uses a token as part of the request body:
I've got a regex extractor to retrieve this value but I can't seem to get it back. I've tested using all the "Field to check" values e.g. Request Header etc. The regext I'm using is "token=(.*?)"
This token is needed as other calls explicitly reference it and I need to pass them this variable
Switch "Field to check" to URL as in your case the token is not in the request body, it's in URL's Query String
Amend your regular expression to look like: token=(.*)
This way you will get the token value into the ${TOKEN} JMeter Variable.
More information:
JMeter: Regular Expressions
Using RegEx (Regular Expression Extractor) with JMeter
Perl 5 Regex Cheat sheet
Query parameters are part of the url, so choose URL as Field to check
Also you are building the URL, so can't you use save the token value before?
I want to use response, refresh_token value as next request input parameter.
I added Regular Expression Extractor there.
I called for regular expression extractor parameter as below on next request.
But still getting invalid refresh token error.
You have use regular expression to fetch data from "Response Message". Instead, you need it from "Body". Change "Field to Check" from "Response Message" to "Body" in regular expression extractor.
Hope it helps.
My expectation is that you need to use access_token, not the refresh_token. Refresh Tokens are required only when your access token is expired as requesting a new access_token using the refresh_token is a way faster and easier than doing full authentication.
Also be aware that it's better to use JSON Extractor to deal with JSON data, the relevant JSON Path query will be as simple as
$.access_token
See API Testing With JMeter and the JSON Extractor article for more information if needed.
This issue has a checklist of things to check for the error you are getting.
Using Refresh Token Exception { "error" : "invalid_grant" }'
Hope it helps.
I think the issue might be with the missing bearer type prefix, try extracting the bearer type as well

I'm trying to extract the CSRF token so I can log in, and be able to obtain cookies, but I'm not able to.
I'm able to get a 200 response code when accessing the URL that contains the CSRF token, and I'm able to see it on the browser and the console, but my response assertion is not able to assert anything regardless of me changing the apply to, field to test, and pattern matching rules sections. My regular expression extractor isn't able to get anything either. All the headers to get to the URL are there. Any suggestions?
Forgot to mention, I'm able to get it on one server that's exactly (or should be) exactly the same as this one...
EDIT:
I placed it under the HTTP Sampler that has that response, and here is an example of what I get for my response assertion. I've also added various images.
Unfortunately you didn't share your output, so I cannot tell for sure, but although it seems your RegEx is correct in both cases, it could be that it doesn't match due to some extra spacing.
It appears that you are expecting a valid JSON, so instead of RegEx you could use JSON Extractor and/or JSON Assertion, for which extra spacing will not matter.
Example: if Response Data is
{"token":"12345"}
I can specify JSON Extractor as
(most important line is JSON Path: $.token)
and the result will be variable token with value 12345.
Here's a good online JSON Path tester, which can help you to figure out the right JSON Path.
If your goal is to check presence of a JSON Object with name of token and an arbitrary value I would recommend going for JSON Assertion instead.
Add JSON Assertion as a child of the request you would like to assert.
Use the following JSON Path query:
$.token
JSON Assertion is available since JMeter 4.0
If you still want to go for the Response Assertion - configure it as follows:
Pattern Matching Rules: Contains
Patterns to Test: {"token":"(.+?)"}
What should be the Regular expression if I want to extract the value for access token, So that i can use it in Path of other Http request ie like access_token=93ee29b4-74dc-4uu7-8e10-6eac6845511b from below http response.
{
"access_token":"93ee2tum-1234-56789-8e10-6eac684551tum",
"token_type":"Bearer",
"expires_in":3600,
"scope":"test"
}
I have given regular expression as
"access_token":"([^"]+)"
And also where can i check the value of regular expression I am getting
You can test your Regular Expressions using View Results Tree listener in RegExp Tester mode like:
Also you can use Debug Sampler to see the associated JMeter Variables. See How to Debug your Apache JMeter Script article for details.
Starting from JMeter 3.0 it's more handy to use JSON Path PostProcessor, in that case the relevant JSON Path Expression would be as simple as:
$.access_token
You can add following regex. It will get the token and depending on the name variable you set, you can add one BeanShell Post-processor to print the token in console for you to verify. Just add the following to it:
log.info(vars.get("token"));
// token is the variable name which you specify in Regular Expression Extractor.
I am new to jmeter. Can anyone help me to use a response object of one request to be passed as a request header of next HTTP request ?
Let me explain.
I am getting an access token along with the response of login in my app:
{: "responseCode":18, : "message":"Successfully logged in.", : "responseObject":"8zWExE4eSdhcJDwnW9MgIw=="}
No I want to use this access token (8zWExE4eSdhcJDwnW9MgIw) as one of the parameter of next request.
I used JSON Path Extractor for this.But its not working.
I am using JSON Path Extractor as well and it works great if it is properly configured.
Just put it into request and fill fields:
Variable Name: access_token (or any other you want to use later in request like this ${access_token})
JSON Path: responseObject should be enough if the JSON you pasted is full response (thjose additional colons are just some mistakes when copy-pasting or the JSON is corrupted?)
Default Value: I always use some value like 'NotUpdated!' here so I can assert in the next step or at least see it easily in request.
Not seeing the full response it is quote hard to come up with a correct JSON Path expression.
Given what you posted it should be something like $.responseObject
See JSON Path Syntax guide for queries syntax examples and Using the XPath Extractor in JMeter (scroll down to "Parsing JSON") for plugin installation instructions and XPath to JSON syntax mapping.
Just in case anybody would face an issue with multiple variable extractions using JSON Extractor (like me), make sure to:
List the names of variables/path expressions/default values using a semicolon as a separator.
Provide default values for every variable.
The second point is apparently required, and I only found out about it from this
Medium post.
