allow passing of jmeter variables in post data

[asfimport]

Chris Cooper (Bug 43850):
I recently modified source code to enable me to insert variables into post data
quite easily actually. In HTTPSampler when sending post data and iterating
through the GUI arguments just changed the code to look something like this:

while (args.hasNext()) {
HTTPArgument arg = (HTTPArgument) args.next().getObjectValue();

            int left = arg.getValue().indexOf("{");
            int right = arg.getValue().indexOf("}", left);
            
            String val = arg.getValue();
            if ((left != -1) && (right != -1)) {
            	// we may have a variable
            	String varName = arg.getValue().substring(left + 1, right);
            	val =

JMeterContextService.getContext().getVariables().get(varName);
// this variable isn't defined or this wasn't actually a variable
if (val == null)
val = arg.getValue();
}

            parts[partNo++] = new StringPart(arg.getName(), val,

contentEncoding);
}
This allows for a variable defined by JMeter to be inserted, particularly useful
for multiple threads needing different values in a URL and if the variable
doesn't exist it just keeps the value in.

Variable substitution already works for POST arguments in JMeter 2.3.

If it is not working for you, please attach a test case to this issue.

I am using JMeter 2.5.1 and using the 'Random Variable' - the variable substitution does not work for POST data.
I did:

1. Create a random variable 'myVar'
2. Created a http request - method POST
3. Added a file in the 'Send Files With the Request' (Note: 'Use multipart/form-data...' is un checked)
4. Used the above created random variable place holder ${myVar} in the file added above step

Tried with JMeter 2.3.4 version which also did not work.

JMeter has never supported variable substitution in external files, only in fields on the Gui screen.

Tried with JMeter 2.3.4 version which also did not work.

See #996 to check that you're in the same scenario.
I think it's a duplicate.
