I'm using jmeter 5.0 to test my web application.How to encrypt the whole bodydata using AES before post ?
I've tried to do it with BeanShell PreProcessor,but it seems there is no method to reset the bodydata,what I found is how to print the bodydata.
log.info("test");
String bodydata = sampler.getArguments().toString();
log.info(bodydata);
I've aleardy known how to implement the AES funtion by importing a java calss.What I expect is resetting the bodydata of plaintext to encrypted text.
Put in body data just a JMeter variable as ${encryptData}
And in preprocessor set the variable with your encrypted value:
vars.put("encryptData", encryptData)
There is Arguments.removeAllArguments() function which clears the sampler body
You can add the new body via Arguments.addArgument() function. Example code:
sampler.getArguments().removeAllArguments();
sampler.addNonEncodedArgument("","your_encrypted_data_here","");
sampler.setPostBodyRaw(true);
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting mainly due to the fact that Groovy has much better performance comparing to Beanshell. So consider migrating to JSR223 PreProcessor on next available opportunity, the same code should work fine.
Under your "HTTP Request" add an "User Defined Variables" (empty values), Make sure as well to key in ${inputJson} in the "Parameters" text field in the "BeanShell PreProcessor" Element.

I want to generate a random name that will be used in the HTTP request in Jmeter for my APIs performance testing. The name would get changed for every thread.
format : "gpt_OverTimePayUsage_<some_random_number>"
The <some_random_number> would change as the thread would change.
I thought of using the JSR2223 pre-processor for each HTTP request and using Java as the language. But I am not sure how to go forward.
The easiest is just using __Random() function like:
${__Random(1111111111111111111,9223372036854775806,)}
JSR223 PreProcessor can be used as well, but in this case consider using Groovy as the language as java is not the real Java, it's Beanshell interpreter and using Beanshell is some form of a performance anti-pattern
I am trying to set value in beanshell inside "CANCEL ORDER" sampler and then use in sampler request body.
Trying
vars.put("orders",Arrays.toString(orderList.toArray()));
and accessing in json request body using ${orders} and its not passing value.
{
"orderIds": ${orders},
"tonce": "${tonce}"
}
POST data:
{
"orderIds": ${orders},
Your "not passing value" doesn't tell anything to us, if your Beanshell script doesn't work as expected first of all you need to check jmeter.log file for any suspicious entries, if your script fails somehow you will be able to see the error message in the log.
It worth checking your orderList variable value using Debug Sampler or printing it to the aforementioned jmeter.log file using log.info() shorthand
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting as:
Groovy has built-in JSON support
Groovy performs much better comparing to Beanshell
How to hardcode the value in JMeter? We need to hardcode field value for each request. Than after the response I need to crosscheck if the response are exactly matching the with the hard coded one. after that only we will be passing the test case. using Beanshell postprocessor
If you want to match the response against "reference" value the best option is using JMeter Assertions, to wit Response Assertion.
If your assertion logic is more complex than equals/contains/matches which can be implemented using the Response Assertion - be aware that since JMeter 3.1 it's recommended to use JSR223 Elements and Groovy language for any form of scripting so my expectation is that you should go for JSR223 Assertion instead.
I have a looping process that will extract some values from a web service (working) and loop through to pull all the information for each value (working).
I need to capture the whole return into a variable so I can modify it and post it back up later.
Screenshot:
When the "Baseline for ..." get kicks in, I get the proper response
But the "Get response" BeanShell PreProcessor is picking up old responses
Screenshot:
Given where my "Get response" object is, I would assume the:
vars.put("ResponceData", prev.getResponseDataAsString());
...would grab the response from "Baseline for ${ID} of site ${callSite}". Please help!
You are using wrong test element. Beanshell PreProcessor is being executed before request therefore it acts properly and returns response from the previous request instead of current one. You need to change it to the Beanshell PostProcessor and your code will start working as you expect.
It is recommended to avoid scripting where possible, if you need to save response data into a JMeter Variable you can do it using i.e. Regular Expression Extractor. According How to Extract Data From Files With JMeter article the relevant configuration will be something like:
Reference Name: ResponceData
Regular Expression: (?s)(^.*)
Template: $1$
If you face a JMeter limitation which cannot be worked around without using scripting make sure you are using the most performing scripting language, since JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language
I am facing some trouble using jmeter. This is my use case, I am using CSV data source parameters to construct a HTTP POST request, the request body is read from a CSV column
which contains some placeholders like ${source_id}
I want to replace these placeholders with jmeter parameters which I am initialising through a regex/json extractor(read from the response of last PUT request). I tried using the jmeter variable name in the CSV file but the variable values are not getting substituted. I guess I will have to use the beanshell pre-processor to modify the HTTP POST request body. Can anyone help with the methods I can use to get the HTTP POST request body.
Something like
String requestBody = sampler.getArguments().getArgument(0).getValue();
should help.
sampler is a shorthand to parent sampler class instance, in your case it will be HTTPSamplerProxy, see the JavaDoc for all available methods and fields.
I would recommend considering migration to JSR223 PreProcessor and Groovy language as it is much faster and less resources consuming than Beanshell. Valid Beanshell code will be valid Groovy code so you should be able to convert to JSR223 elements with no or minimal changes. See Groovy is the New Black article for more details.
