How to extract parameters from response url in Jmeter - jmeter

I've an isssue. I run a test plan in jmeter. I've a http request, response header has a URL with 1 parameter (Ex: response header => URL: http://abc.xyz?code=xxx). Now I want to get the value of parameter "code", and put it into the body of next http request. How can I do that? Please help. Sr if my English not good enough

If I'm correctly getting your requirement and you need to extract the code from a response header which looks like this:
You can do it using a Regular Expression Extractor configured like:

How to retrieve variable from a request body

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?

Is there anyway to pass response of a HTTP sampler to request as another sampler in JMETER

I am testing rest API using Jmeter. In one scenario need to pass complete response of a http sampler to, another http sampler as a request dynamically. Any suggestions how to achieve this in Jmeter.
Add Regular Expression Extractor as a child of the request which response data you want to capture
Configure it as follows:
Name of created variable: anything meaningful, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
That's it, you should be able to refer the extracted value as ${response} where required.
Explanation of the regular expression:
() - grouping
(?s) - single line modifier
^ - line start
. - wild card character
* - repetition

You can get all response using Regular Expression Extractor with regex accepting all characters
In next JMeter 5.2 version you will able to do it using Boundary Extractor by keeping Left and Right Boundary empty

Unable to correlate value[token], from one sampler to another in JMeter

I have recorded script using BlazeMeter plugin and I want to the use access token which I receive in successful login request, in another request. My Test plan looks like as below
Thread Group : [A]
|- HTTP Sampler - Login Page
|-Regular Expression Extractor [getToken]
|-HTTP Sampler - Other Page
|-Beanshell PreProcessor[Set Header in Authorization]
Regular Expression Extractor parameters and values like below :
Variable Name : token
Regular Expression : {“access_token”:”(.+?)"
Template : $1$
Match No. : 0
Beanshell PreProcessor script like below
import org.apache.jmeter.protocol.http.control.Header;
log.info("Start");
sampler.getHeaderManager().add(new Header("Authorization","Bearer"+vars.get("token")));
log.info(vars.get("token"));
Most probably your Regular Expression Extractor fails as your quotation marks look utterly suspicious. You can double check if the token variable really has the anticipated value using Debug Sampler and View Results Tree listener combination. Also check out jmeter.log file for any suspicious entries, if your Beanshell script fails - the cause will be printed there.
The response data of the Login Page seems to be JSON therefore it makes sense to use the JSON Extractor instead of the Regular Expression Extractor. It allows using JSON Path language in order to extract "interesting" bits of data from the responses. In your case the relevant JSON Path expression would be $.access_token
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting so consider migrating to the JSR223 PreProcessor and Groovy language (you can re-use the same code)
You don't even need the scripting, you can add Authorization header (as well as any other header) using HTTP Header Manager
Could you add debug sampler and try first to confirm your regular expression extractor working as expected? It should provide you the required value of token.
If your token has the required value, I will suggest you to add HTTP Header Manager config element by right clicking on HTTP sampler
HTTP Request => Add => Config Element => HTTP Header Manager
In this config element, you can visually add the Headers as below:
Please Note That:- You have not provided any space/hyphen(-) or between keyword Bear and token.

How to use multiple variables from regular expression extractor in HTTP sampler

I have the following json response from HTTP sampler
{
url: "https://example.com/ir/rest/wsVerRest/getFile?filePath=/data/IR/data/IR_Org/user.mail#abc.com/testSample1_testSample2/testSample1_20151201214307897/outputs/CnvActor-00/testCoverage1.seg",
},
{
url: "https://example.com/ir/rest/wsVerRest/getFile?filePath=/data/IR/data/IR_Org/user.mail#abc.com/testSample1_testSample2/testSample1_20151201214307897/outputs/CnvActor-00/testCoverage2.seg",}...{testCoverageN.seg}
From these I have to construct another htto sampler by using the server(ie xyz.itw),url(/ir/rest/wsVerRest/getFile),keyparam(filePath),value(/data/IR/data/IR_Org/user.mail#abc.com/testSample1_testSample2/testSample1_20151201214307897/outputs/CnvActor-00/testCoverage2.seg)
How to get these values using regular expression extractor and use in another sampler.
At present I can use regex to get those values.but don't know how to use in another http sampler.Please help.Thanks

If you are able to get these values via Reg Expression extractor then it will not be a problem for you. When you use Regular expression extractor then the value are stored in "Reference Name" that you mentioned in your Extractor.
Lets say, your reference names were like below:
ServerValue
UrlValue
KeyParamValue
and so on..
you can simply use them like this in your intended HTTP sampler..
${ServerValue}${UrlValue}${KeyParamValue}

Regular expression in Jmeter for a json reponse

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.
See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for more information and XPath to JSON mapping.
