From the string - code-challenge=ndh37hdjdhf\hdhjf-ybd_536\x26
I want to capture only - ndh37hdjdhfhdhjf-ybd_536
I tried regular expression code-challenge=(.+?)\\26, but it takes the character \ along with other, i dont want this character to be part of the regular expression. How i can achieve this.
Please help on this.
Replace this \ character in the resulting JMeter Variable using __strReplace() function like:
${__strReplace(${foo},\\\\,,)}
__strReplace() function can be installed as a part of Custom JMeter Functions bundle using JMeter Plugins Manager
If you cannot or not willing to use plugins the same can be achieved using JMeter's built-in __groovy() function like:
${__groovy(vars.get('foo').replace('\\\'\,''),)}

I have a variable that I use in my API's header.
It contains many special characters in that string so JMeter cannot digest the value.
'myCode' variable I plan to use in CLI (NON-GUI) mode so I need to be able to control it.
Sometimes I see also double or single quotes ('"' and "'")in the string so it can be a case that I need to deal with this
Any ideas on how to handle this?
${__P(myCode,0$M#3C3dKLo&1=9gIYP#CvC5.sWNvDD2mTWmn)=uoj}peA6W8?ry]s/Tn}J{C:Z%,J?M0+{&&ywi]3wM"1lG(&!q++88b1B>I2G1=+cso}trWmOSIo]INi^&%&^GYUFFsgdnJ.TsPTM[Jq+g2CWKvRZ495G0DqH>Yj%sUPqhj2aCmbWun)}
JMeter can "digest" the value, if you're trying to override the property via -J command-line argument - refer to your shell documentation as some characters might need escaping.
Another option is defining your property in user.properties file or in a completely separate file and using __FileToString() function to read it
I'm capturing multiple values with a regular expression, and that expression returns 20 matches as shown in image RegExMatches,
My regular expression is something like this RegEx.
How do I use multiple values in post data of my HTTP request which is something like PostData
I tried with MatchNR and -1 and call with ${candidateGUID_gN} N being the match number but this didn't workout.
How do I use the Extracted values in Post data ? or will I have to make different Regular Expressions for each value ?
I think the only way of achieving this is building your request using JSR223 PreProcessor and Groovy language, take a look at the following JMeter API shorthands:
Arguments
vars aka JMeterVariables
sampler aka HTTPSamplerBase

And please stop posting code as images it's not very polite / disrespect to the community.
Please could someone help me with this simple IF condition in Groovy? I have obtained a value (],) from a RegEx and am trying to use it in the subsequent groovy IF condition. I had the below which is not working:
${__groovy(vars.get("Results_Flag").contains("],"),)}
You need to escape comma , with a backslash \ so your condition should look like:
${__groovy(vars.get("Results_Flag").contains("]\,"),)}
Take a look at JMeter Functions documentation:
If a function parameter contains a comma, then be sure to escape this with "", otherwise JMeter will treat it as a parameter delimiter.
If you take a look at jmeter.log file you should see something like:
invalid variables in node If Controller
org.apache.jmeter.functions.InvalidVariableException: __groovy called with wrong number of parameters. Actual: 3. Expected: >= 1 and <= 2

I am trying to execute beanshell script in jmeter for a URL parameter value. I have the following:
${__BeanShell(vars.get("query").replaceAll(" ","%20"))}
The jmeter console outputs this:
Caused by: bsh.ParseException: In file: inline evaluation of: ``vars.get("query").replaceAll(" ";'' Encountered ";" at line 1, column 33.
I can't figure out what the problem is as the character there is a , not a ;.
You're doing something ridiculous. Encoding an URL is not only about escaping spaces, looking into URLEncoder documentation you will need to handle:
All non-Latin non-alphanumeric characters
All characters apart from ., -, *, and _
Which might be very tricky.
So you basically have 2 options:
Use JavaScript encodeURIComponent() function via JMeter's __javaScript function like:
${__javaScript(encodeURIComponent("${query}"),)}
Or use aforementioned URLEncoder from __groovy() function like:
${__groovy(URLEncoder.encode(vars.get('query')\, 'UTF-8').replaceAll('\\\+'\,'%20'),)}
Performance-wise in cases of high loads Groovy is preferred option, check out Apache Groovy - Why and How You Should Use It article for more details.
See JMetrer's functions tutorial, you need to escape every comma:
If a function parameter contains a comma, then be sure to escape this with "\", otherwise JMeter will treat it as a parameter delimiter.
In your case
${__BeanShell(vars.get("query").replaceAll(" "\,"%20"))}
Also consider using __groovy function instead of __BeanShell for better performance.
Please use below code in Beanshell PreProcessor or BeanShell PostProcessor in order to replace single space character to '%20':
String myString = vars.get("query");
String new_var = myString.replaceAll(" ", "%20");
vars.put("updated_value", new_var);
You can further use 'updated_value' variable having space replaced by '%20' in next requests.
Please refer to the JMeter Knowledge Base for more information on JMeter elements.
In Jmeter, I can able to extract the value using regular expression extractor, but while parsing the value I need some changes in the value as below.
Example,
Suppose If I extract this value in regular expression extractor (single Value in multiple lines),
PHNhbW+xwO
U0FNTDoyL
cmFjbGUu+
Here
I Need to replace + by %2B, need to add %OD%OA at the end of each line and multiple lines to a single line as below.
PHNhbW%2BxwO%OD%OAU0FNTDoyL%OD%OAcmFjbGUu%2B%OD%OA
I need to parse this as a single parameter value.
I think you can use __javaScript() function which allows calling arbitrary JavaScript code and inside JMeter __javaScript() funciton you can call EcmaScript EncodeURIComponent() function
It will automatically convert all newline characters \r\n to %OD%OA and + to %2B and in fact any character except alphanumeric and these ones:
_ . ! ~ * ' ( )
