Re: Dynamically changing the content of HTTPRequest defaultdata

setDataFromFile() reads the file and sets the "data" for the request to
its bytes.

Supposing you just want to change the report_id string, you might script
that as follows:


from java.lang import String

# ...

  request3 = createRequest(Test(203, 'POST importWeb'), url0)
  request3.setDataFromFile('http-data-0.dat')
  dataAsString = String(request3.getData()) #1
  dataAsString = String(dataAsString.replace("report_id",
"some_other_id")) #2
  result = request3.POST('/importWeb',
        dataAsString.getBytes(), #3
        (NVPair('Content-Type', 'multipart/form-data'), ))


Here we get the byte array and convert it to a Java string (#1); use the
Java String replace() method to alter the content (#2); then convert it
back to a Java byte array (#3).


How you generate "some_other_id" is up to you. See
http://grinder.sourceforge.net/faq.html#simulating-users for an example
of picking strings randomly from a file.
