I am extracting the HTML response code from a samplier. I would like to use the if controller to conditionally extract more information if the right response code is returned.
So teh Get Message Response Extractor would save the response code to the variable: GetMessageResponse.
Then the If Controller would check if GetMessageResponse is 200:
If this is true then extract more information like this:
However I am not getting anything in ResponseText, what am I doing wrong?
You can do it in one shot if you switch to the JSR223 PostProcessor, the relevant Groovy code would be:
import com.jayway.jsonpath.JsonPath
if (prev.getResponseCode() == '200') {
def responseText = JsonPath.read(prev.getResponseDataAsString(),'$.MessageObj.Text').get(0)
vars.put('ResponseText', responseText)
}
else {
vars.put('ResponseText','Response code is: ' + prev.getResponseCode())
}

Apache Groovy - Why and How You Should Use It
In JMeter what you do is extract whatever the response and set Default Value field to something that will be filled when response will not contain extraction, for example for JSON Extractor:
What you show will not work because you put Extractors in IfController, as there is no Sampler, nothing will happen due to scoping rules.
Also when you'll need for another thing to use If Controller, no need to extract response code, just use:
${JMeterThread.last_sample_ok}

Below is the JSON Response from the Server, How to remove the characters �� from the below Response using Jmeter
Response :
{"_id":"5d56cc5c31acfd001298e863","test_id":"5d56cc593801370012bdb2bb","display_order":"1","question_type":"MULTIPLE CHOICE","isbn":"9780393630749","status":"added","question":{"_id":"5d56cc5c31acfd001298e864","questionId":"5d4262bb56c1d800122fcb48","QuestionTitle":{"key":"","value":"","valueRTF":"","valueHtml":"��������\n
I have written the groovy Script. but it is not removing the char.
def response = prev.getResponseDataAsString();
def var1= response.replaceAll("\�", "");
and I need to use this Var1 in another request.
Most probably you're seeing these question marks due to encoding problems, try setting file.encoding property to UTF-8 in system.properties file and restart JMeter, most probably you will see normal text instead of the question marks.
If for some reason the above hint is not applicable I would recommend replacing the whole valueHtml attribute value using JsonBuilder, the relevant code would be something like:
def builder = new groovy.json.JsonBuilder(new groovy.json.JsonSlurper().parse(prev.getResponseData()))
builder.content.question.QuestionTitle.valueHtml = ''
vars.put('Var1', builder.toPrettyString())
As the result you will have the same JSON structure with empty valueHtml attribute.

Apache Groovy - Why and How You Should Use It
As it is a JSON Response, add JSON Extractor Post Processor to the Parent Sampler from where the Response is expected. Extract whole JSON with following settings:
Now, use a JSR223 Sampler, with following code in script area:
String var1 = vars.get("jsonOutput");
log.info("Output: " + var1);
String replaceString=var1.replace('?','-'); // replace with whatever you want to, I am replacing it with '-'
log.info("Output: " + replaceString);
vars.put("NewString", replaceString);
Afterwards, you can use ${NewString} wherever you want.
I have a http request which gives json output as :
{
"MESSAGE_CODE":200,
"MESSAGE_DESCRIPTION":"OTP Generated Successfully",
"data":
{
"otp":"123456",
"otpGeneratedDate":"yyyy-mm-dd"
}
}
I want to use otp as the input parameter in json for my next http request.
I have added JSON extractor with following configuration :
enter image description here
Names of created variable : OTP
JSON path expressions : $..data.otp
Match No. : 1
But still when I am calling this parameter as
"otpNumber": "${OTP}" in my next input JSON http request, its not getting called.
and value is passed as ${OTP} for otpNumber
How can I handle this
As per JMeter Documentation:
Variables, functions (and properties) are all case-sensitive
So you need to change this line:
"otpNumber": "${OTP}"
to this one:
"otpNumber": "${otp}"
and your test should start working as expected.
You can observe which JMeter Variables are defined along with their values using Debug Sampler and View Results Tree listener combination.
I would like to know best way to verify entire Json response in Jmeter. Can somebody help. Thanks.
The easiest way is use JSR223 Assertion and JsonSlurper class like:
Put the anticipated JSON into expected JMeter Variable using i.e. User Defined Variables test element like:
Add JSR223 Assertion as a child of the request you want to validate
Put the following code into "Script" area:
def expected = new groovy.json.JsonSlurper().parseText(vars.get('expected'))
def actual = new groovy.json.JsonSlurper().parse(prev.getResponseData())
if (expected != actual) {
AssertionResult.setFailure(true)
AssertionResult.setFailureMessage('Mismatch between expected and actual JSON')
}
If there will be any difference between expected and actual JSON - the sampler will be marked as failed
Hi I am passing an email which is a time function like below
email = ${__time(MMddyy)}_${__time(HMS)}#yopmail.com
The value of this function changes eveytime I call the variable email.
I would like to store this value that is generated from this function into a variable and use that in other requests.
So currently I am getting two different emails in two different http requests since there is some time lag between my two http requests.
what I would like to do is .. store the email that is being sent in first http request by extracting the value from the request and pass it in the second http request.
POST data:
email=062915_160738%40yopmail.com
I know the way to extract from html response.. but is there any way to extract from request in jmeter?
If so can someone pls tell me how to achieve this?
thank you
Add a Beanshell PostProcessor as a child of the request which sends that POST request
Put the following code into the PostProcessor's "Script" area
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);
if (arg.getName().equals("email")) {
vars.put("EMAIL", arg.getValue());
break;
}
}
Refer generated value as ${EMAIL} where required.
Clarification:
above code will extract the value of email request parameter (if any) and store it to EMAIL JMeter Variable
ctx - shorthand to JMeterContext class instance
vars = shorthand to JMeterVariables class instance
Arguments and Argument - you can figure that out from JMeterContext JavaDoc
See How to use BeanShell: JMeter's favorite built-in component guide for more information on Beanshell scripting in JMeter.
Instead of the entire email, you can store the timestamp value in a variable and then use this timestamp variable to create email anywhere you want.
This way you will can have same email every where.
Add a Beanshell PostProcessor & Add following script:
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 req_body = arg.getValue();
vars.put("req_Json",req_body);
}
here we get the output in json format:
${req_Json}=
"email":"062915_160738%40yopmail.com",
"name":"abc xyz"
Now using jp#gc Json Path Extractor extract the value of email
Json expression = $['email']
and store the value in email_value_extacted
now use the variable ${email_value_extacted} anywhere you want to use.
finally,
${email_value_extacted} = 062915_160738%40yopmail.com
Is it HTTP Sampler? If so, just put into beanshell postprocessor:
String prevQuery = prev.getQueryString(); //your request text
System.out.println(prevQuery );
Also works for any samplers:
String prevQuery = prev.getSamplerData();
You can use Regular Expression extractor to extract the e-mail address from the request URL.
Add Regular Expression Extractor as a child of sampler which sends the post request.
In the Regular Expression Extractor select URL in Response Filed to check instead of Body.
You should be able to extract e-mail id from the request in this way.
Having the following request:
From this I extract using the Regular Expression Extractor the following string:
%5B1172%2C63%2C61%2C66%2C69%2C68%5D
I decode this using the urldecode function: ${__urldecode(${Groups_g2})}
Decoded: [1172,63,61,66,69,68]
On the following request I want to extract the values using the BeanShell PreProcessor to obtain a list of parameters like this one:
I know that I have to use sampler.addArgument but i can't figure how to extract data from the list and add the values as parameters.
Try the following:
Put ${__urldecode(${Groups_g2})} into Beanshell PreProcessor's Parameters input field
Enter the following code into Script area
String params = Parameters.substring(1, Parameters.length() - 1); // remove square brackets
int counter = 1;
for (String param : params.split(",")) {
sampler.addArgument("parameter" + counter, param);
counter++;
}
I have no idea what parameter names need to look like, hopefully above information will be helpful.
HTTP Request with no parameters:
Beanshell PreProcessor
Parameters in View Results Tree Listener
