I was using JSR223 preprocessor and passing value to it's main request but value is not being return in that request.
How do I pass the value in the HTTPS request extracting from JSR223 preprocessor. In more I need to do parametrization. I am calling NodeJS code.
You need to use vars shorthand for JMeterVariables class instance in order to save the generated encoded value into a JMeter Variable.
i.e. in the last line of your script do something like
vars.put('password', response)
and in the HTTP Request sampler's request body use something like:
"password":"${password}"

I know we can send/initialise the post data parameter variables from preprocessor but my requirement is i want to send complete post data/pay load which is shown in my screenshot from jsr223 preprocessor.
You have sampler shorthand which stands for HTTPSamplerProxy in the JSR223 PreProcessor
There is HTTPArgument class where you can specify name, value and whether they're encoded already or JMeter should perform the URL-encoding itself
So for each parameter you want to pass you need to add the line like:
sampler.getArguments().addArgument(new org.apache.jmeter.protocol.http.util.HTTPArgument('parameter_name', 'parameter_value', false))

I have 2 graphql http requests as following.
The first http request's response returning json like so:
{"data":{"customers":{"customerIds":["0e1c7b05-79c6-40c6-9144-7230a836fe04", "45677b05-79tt-56c6-9144-7230a836bbbb"]}}}
I then created the json extractor and the beanshell to save the customer ids in the property
The 2nd Http request then using the above customerids property as part of the graphql request body
but I;m getting the 500 InternalServerError due to the quotes in the list customerids below not being escaped. how can i escape them ?
POST data:
{"query":"query getCustomerInfo {\n getCustomerInfo(customerIds: \"["0e1c7b05-79c6-40c6-9144-7230a836fe04"]\") {\n firstName\n lastName\n school\n }\n}"}
Don't inline JMeter Functions or Variables into your scripts
When using this feature, ensure your script code does not use JMeter variables directly in script code as caching would only cache first replacement. Instead use script parameters.
Don't use Beanshell, since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting
So replace your Beanshell Assertion with the JSR223 PostProcessor and use the following code:
props.put("customerIds",vars.get("customerIds").replaceAll("\"","\\\\\""));
This way you will get the following customerIds property value:
[\"0e1c7b05-79c6-40c6-9144-7230a836fe04\",\"45677b05-79tt-56c6-9144-7230a836bbbb\"]
I am using two soap/xml request samplers wherein response of one is to be used in request of the other. The issue is that the response of Sampler1 contains multiple occurrences of "a:" which has to be replaced by "eas1:" which can be used in Sampler2. Kindly suggest a solution.
I tried using beanshell postprocessor but could not come to any positive result.
Add JSR223 PostProcessor as a child of the Sampler1
Put the following code into "Script" area
def response = prev.getResponseDataAsString()
def request = response.replaceAll('a:', 'eas1:')
vars.put('request', request)
Use ${request} in the "Body Data" section of the Sampler2
References:
prev is a shorthand to SampleResult class instance which provides access to the parent Sampler result
vars is a shorthand to JMeterVariables class instance, it provides read/write access to JMeter Variables
String.replaceAll() method reference

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.
In my JMeter script, I have one HTTP request which has 4 different parameters to be passed in post body. I have corresponding variables. Values of these variables are not available every time, depending on configuration.
If a value is not available, I get an error "bad request". How do I see if a variable is not null and only then pass corresponding parameter in request post body?
Given you have the following configuration:
and you don't want to send foo parameter if ${bar} variable is not defined
Add Beanshell PreProcessor as a child of your HTTP Request Sampler
Put the following code into the PreProcessor's "Script" area:
if (vars.get("bar") == null) {
sampler.getArguments().removeArgument("foo");
}
Where:
vars - is a shorthand to JMeterVariables class instance
sampler - shorthand to parent sampler implementation class instance, in this case - HTTPSamplerProxy
See How to Use BeanShell: JMeter's Favorite Built-in Component guide for more information on using Java and JMeter API from Beanshell scripts.
Just use the Logic Controller - If Controller. It allows to define the if statement using your variables. So, you can perform your actions only in case all parameters are not equal to null:
I've defined one single User Defined Variable in this example. Jmeter sends HTTP request only if it has a value defined.
