Hi, I'm looking for some suggestions on how to pull a random number of lines from a file and concatenate them together for a single HTTP request. In a bit more detail:
I have a CSV file (two columns, but I'm only interested in the first column) with almost 200,000 lines. Each line contains a unique id. I then want to pull a random number of ids (between 1 and 60), join them with a comma delimiter and make an HTTP request with the whole string. For example, the file might contain: http://rest.acme.com:8888/items/130,127,2,97 or http://rest.acme.com:8888/items/127,26,31 Where 130, 127, 2, etc; are ids pulled from the file. I can pre-sort the file randomly if I need to, so reading the lines in the file in sequence is not a problem. I tried a number of approaches using a CSV Data Set, or __CSVRead. In general, my approach was to use a Loop controller with a random number as the "Loop Count"; and then use a BeanShell Pre-Processor or a UserParameters expression to concatenate the values. I tried using a variable and using a property. But none of this worked... it seems that the values created inside the loop are not available to the HTTP request outside the loop. Any suggestions on how I might be able to do this. Marc
