I have a GET request from where I extract the variable ${SAMLRequest} (Regular Expression Extractor).
Value of ${SAMLRequest} is as follows: VhJUVNXeHBPRjNMdnNvNHpTUT09PC9YNTA5Q2VydGlmaWNhdGU+PC9YNTA5RGF0YT48L0tleUluZm8+PC9TaWduYXR1cmU+PHNhbWxwOk5hbWVJRFBvbGljeSBBbGxvd0NyZWF0ZT0idHJ1ZSIgLz48L3NhbWxwOkF1dGhuUmVxdWVzdD4=
Next I have a POST request, and I want to post the variable ${SAMLRequest} with some changes.
Instead of the sign + I want to have %2B and instead of =, I want to have %3D.
Do you know how I can change a variable in JMeter?
Use beanshell preprocessor1 in your post sampler
The easiest way is to check "Encode?" box for SAMLRequest parameter in your POST request body
The harder way is using __urlencode() JMeter Function.
The hardest way is BeanShell Pre Processor as okwap suggests. However it'll give you the full control.
Relevant Beahshell code will look like:
import java.net.URLEncoder;
String source = vars.get("SAMLRequest");
String encoded = URLEncoder.encode(source);
vars.put("SAMLRequest", encoded);

I'm new here and also a beginner on JMeter and maybe this was already answered in an old post that I didn't find, sorry if this is the case.
I had this Post request I need to send with all these IDs that vary according to the account
Post Request
In order to get all of the IDs, I used the JSon extractor to put then into a variable
JSon extractor, then I got all the FieldIDs that I need.
ID extracted
But now how can I add this variable inside the request? I tried something like {"ids":"${fieldId}","includeBoundary":true} but it didn't work. How can I use this?
Please see: HTTP Request parameter dialog example
If you need to extract the whole response, save it into a JMeter Variable and send it back to another endpoint - the easiest way is using Boundary Extractor providing empty left and right boundaries
If you need more complex transformations - take a look at JSR223 Test Elements and Groovy language
I solved my problem in a so easy way(damn it)!!!!
On the Json extractor I just marked the option "Computer concatenation var (suffix_ALL)" then on the debbuger I got all IDs I needed in only one line and finally on my request I just add on the body data the line {"ids": [${fieldId_ALL}],"includeBoundary":true} and bingo it worked like a charm!!!!
In my first request I am able to extract the value using Regular Expression Extractor which is clearly visible into the debug sampler. The value is extracted by setting the following options in Regular Expression Extractor:-
Name of Created Variable:- instanceUID
Regular Expression:- "InstanceUid":"(.*?)"
Template:-$1$
Match No:-1
Default Value:- (Blank)
The value that I want to pass in the next POST request is visible as:-
instanceUID_g1=2ab5dfb8-a217-4ff2-9025-523565b7b7ad
And the body for the next HTTP POST request is set like this:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"${Registry}"}}
When this request seen in detail inside View Results Tree looks like:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"AAX"}}
As seen the value of ${instanceUID_g1} did not get substituted in the POST body as was for variable ${Registry} which was taken from CSV config.
Being new to Jmeter can anyone suggest what did I miss?
Most probably your Regular Expression Extractor placement is not very correct, be informed about JMeter Scoping Rules concept
If you place Regular Expression Extractor as a child of the request - it will be applied to this request only
If you place Regular Expression Extractor at the same level as several requests - it will be applied to all of them
in the latter case it will be applied 1st to 1st sampler, then to Debug Sampler, then to 3rd sampler so on 2nd step it will be overwritten, most probably that's your problem
Also it appears that you're getting the data from JSON so it makes more sense to use JSON Extractor or JMESPath Extractor
My task is to make a request and save some data from the headers in a variable and use it later in another requests.
So I've added an http request and added an regular expression extractor. Here is my setup:
And then I've created another request and I'm using the LocationToken variable, but there the variable has the default value (dd). here is the response:
So, as you can see, the pattern patches on the headers. So what have I done wrong?
In Regular Expression Extractor, under Apply to section, you should select Main sampler and sub-samplers option but not JMeter Variable.
Regular Expression Extractor saves the value into the variable which we specified in Reference Name field.
in the question,
Reference Name: LocationToken
in later request, you refer the value as follows:
${LocationToken}
I want to extract value of the parameter sent through post request in jmeter.
I know the use of regular expression for extracting response value or request URL but here I would like to extract the value of post request.
I've been thorough how to extract value from request in Jmeter but it didn't worked.
Not sure why do you need it as given you sending "something" you should already have that "something" hence you don't need to extract it, however here you go:
In order to save 1st parameter value (or the whole post data if you use "Body Data" mode):
Add Beanshell PostProcessor as a child of the HTTP Request.
Put the following code into the PostProcessor's "Script" area:
String request = ctx.getCurrentSampler().getArguments().getArgument(0).getValue();
vars.put("request", request);
You will be able to access extracted value as ${request} where required.
Clarifications:
ctx - shorthand for JMeterContext class instance
getCurrentSampler() - in case of HTTP Request sampler stands for HTTPSamplerProxy
See How to Use BeanShell: JMeter's Favorite Built-in Component guide for more information on using JMeter and Java API from Beanshell test elements in your JMeter test.
I added a Beanshell PostProcessor in my http request with following code.
import org.apache.jmeter.config.Argument;
import org.apache.jmeter.config.Arguments;
Arguments argz = ctx.getCurrentSampler().getArguments();
for (int i = 0; i < argz.getArgumentCount(); i++) {
Argument arg = argz.getArgument(i);
String a = arg.getValue();
vars.put("EMAIL",a);
}
Explanation: I get a my request as a json and put it in EMAIL. Now I can use EMAIL as a variable in my other request.
Then, I added a jp#gc Json Path Extractor and I applied it to a Jmeter Varaible.
Now, Email will be used as variable, which contains my json request and I can extract using jsonPath Extractor.
An easy way to do this is using the JSON Path Extractor.
There are just
For the example you gave
{ "data" : { "name" : "john_doe", } }
'Variable Name: YourNewVar'
'JSON Path: $.data.name'
Should work, but you may need to do some experimenting.
You may want to add a "debug sampler" (its one of the standard samplers) and put in its title $YourNewVar so you can see what is being extracted.
Beanshell and "Regular Expression Extractor" will work, of course, but may be a little harder to use if you are not familiar with them.
I have created a User Defined Variable with name as "Status" and a default value as "Started".
I got a HTML Response, with following content:
<SPAN id="ApplicationStatus"> Interrupted</SPAN>
I want to get the Span Id value and use in beanshell samplers to process further either in If Controller or Switch Controller.
I used Regular Expression extractor to extract the value needed and its working too.
But when i say vars.get("Status") will always return me the default value "Started".
Is there a way where i can extract the required value "Interrupted" and substitute that to the user defined variable "Status"?
Yes you can get that value of #ApplicationStatus into your User Defined Variable (UDV).
You can use regex but really you shouldn't for this type of parsing I'm not going to get into many reasons why.
Here is how you can do it using alternative (better solution IMHO) :
String html = "<SPAN id=\"ApplicationStatus\"> Interrupted</SPAN>";
Document doc = Jsoup.parse(html);
String value = doc.select("#ApplicationStatus").first().text();
//Put value in UDV Status
vars.put("Status", value);
You can add this to your sampler that does this kind of parsing i.e Beanshell sampler, here are the imports (which go above this code) :
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
Please note that this code is Jsoup dependent so you will need to download jsoup jar and put it in your $JMETER_HOME/lib directory.
Hope this sheds some light on your issue.
Update
If you want to avoid Java, I've written small jmeter post processor component that extracts text value from HTML element. Take a look at :
https://github.com/c0mrade/Html-Extractor
If you go over the steps how to install the post processor from the page above, you would use it as follows :
Right click on your sampler. Add a Post Processors -> Html Extractor , in the jquery selector field write #ApplicationStatus and store result in variable of your choice (Status). Following this add Debug Sampler, if in your Debug sampler there is variable Status with the value Html Extractor is working! you're done!
I can't reproduce your issue.
Here is my plan:
- User defined variables with variable Status
- Thread Group
- HTTP Request
- Regular expression extractor with reference name = Status
- Beanshell Sampler that logs Status variable
Beanshell sampler logs value that was received in Regular Expression Extractor
