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 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": ${orders},
Your "not passing value" doesn't tell anything to us, if your Beanshell script doesn't work as expected first of all you need to check jmeter.log file for any suspicious entries, if your script fails somehow you will be able to see the error message in the log.
It worth checking your orderList variable value using Debug Sampler or printing it to the aforementioned jmeter.log file using log.info() shorthand
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting as:
Groovy has built-in JSON support
Groovy performs much better comparing to Beanshell
I have Http Sampler body as follows,
{"Uname":"admin","Signature":"${Sign}","LoginTime":"${LogTime}","Action":"Do_Action"}
I have to get the value of "Action" from the above body, and that value nned to be sent to Pre-processor which will be useful to do further action.
Help me out of this...!!
Thanks!
I would recommend switching to JSR223 PreProcessor and Groovy language as:
Groovy has built-in JSON support
Groovy performs much better than Beanshell
Example Groovy code to extract "Action" from the request body and store it into ${action} JMeter Variable will look like:
def body = new groovy.json.JsonSlurper().parseText(sampler.getArguments().getArgument(0).getValue())
vars.put('action', body.Action)
See Groovy is the New Black article for more details.
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.
I saved the whole XML in a DB table and am fetching the XML in JDBC sampler and using it in HTTP sampler. I want to parameterize a value inside a particular tag value inside this fetched xml at runtime. Could someone tell me how to do that. Thanks in advance
In http sampler ==> post body
xmldoc = ${xmlfromdb}
Here am able to fetch the whole XML and I can submit it successfully. How to parameterize a tag value inside this fetched xml at runtime.
You can do it via scripting like:
Add Beanshell PreProcessor as a child of the HTTP Request sampler
Put the following code into the PreProcessor's "Script" area
String body = sampler.getArguments().getArgument(0).getValue();
body = body.replace("Original Tag Value", "New Tag Value");
sampler.getArguments().removeArgument(0);
sampler.addNonEncodedArgument("", body, "");
sampler is a pre-defined variable available for Beanshell (and some other Test Elements) which stands for parent Sampler instance and in case of HTTP Request it's HTTPSamplerProxy. See JavaDoc for more information on available methods and fields and How to Use BeanShell: JMeter's Favorite Built-in Component article for more information on using JMeter and Java API from Beanshell test elements inside JMeter script.
I have to give dynamic values to url which takes number of users and their age , which can be selected though web page. but I want to give it in Jmeter using BeanShell PostProcessor.
Help me in this,since I'm new to Jmeter.
This is the path:
/destinations/packages?airports%5B%5D=LGW&units%5B%5D=000577%3ADESTINATION&when=29-05-2016&until=&flexibility=true&flexibleDays=3&noOfAdults=2&noOfSeniors=0&noOfChildren=1&childrenAge=3&duration=7114&first=0&searchType=search&searchRequestType=ins&sp=true&multiSelect=true
from what I've got looks like you can use CSV Data Set Config.
Create .txt file with the data you want to feed your test with;
Place the above .txt file to the folder where your .jmx file lies;
In your Test plan: Under your request sampler - place CSV Data set Config;
Then if you need to use your dynamic values within one threadgroup => refer these data as ${quanity}, ${age} in you url.
If you need to pass these values across the threadgroups => add BeanShell Assertion
Then (in the other Tread group) refer those as ${__property(_quantity)},${__property(_age)}.
Hope, it helps.
First of all you need Beanshell PreProcessor, not Beanshell PostProcessor.
All this parameters are basically name/value pairs which can be defined via HTTPSamplerBase class. HTTPSamplerBase class instance is available to Beanshell PreProcessor as sampler pre-defined variable so if you add the following code into the Beanshell PreProcessor "Script" area
sampler.addEncodedArgument("airports[]","LGW");
sampler.addEncodedArgument("units[]","000577:DESTINATION");
sampler.addEncodedArgument("when","29-05-2016");
sampler.addEncodedArgument("until","");
sampler.addEncodedArgument("flexibility", "true");
sampler.addEncodedArgument("flexibleDays","3");
sampler.addEncodedArgument("noOfAdults","2");
//etc
Your HTTP request will be populated with the values, you set via Beanshell.
JMeter Variables can be accessed via vars shorthand which stands for JMeterVariables class instance.
String airport = vars.get("airport");
sampler.addEncodedArgument("airports[]", airport);
//etc
See How to Use BeanShell: JMeter's Favorite Built-in Component article for comprehensive information on how to use Beanshell Test Elements in Jmeter.
Remember that it is recommended to avoid scripting where possible so if there is another way of implementing your task - go for it.
