Getting oauth token using Jmeter xpath extractor and using it in path of other Http Request - jmeter

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.

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?

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 Re-use data generated by one Response to other request?

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.

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}

Unable to read the token id from json response code using regular expression extractor in JMeter

I have to do performance testing for ipad application.
There is scenario in which i have to read the token id from the response and use this token id in my next request.
I used the regular expression extractor, but when i used the variable in next request i.e. ${tokenid}, it wasn't replaced with the captured value. When i look at View Result tree, it is simply requesting the variable instead of token.
Here is the regular expression extractor
There is at least an error where you must check:
Body
instead of checking :
Response Code
in Regular Expression Extractor
You can use View Result to check your regexp:
Finally regexp should be:
"Token":"([^"]+?)"
