Thank you again :)
I used Groovy way and to detect MIME type automatically
URLConnection.guessContentTypeFromName() method is used. I declared two
arrays with file paths and parameters so we can put as many files as we
want to upload:
import org.apache.jmeter.protocol.http.util.HTTPFileArg
def filePath = ["uploadFiles/desktop.jpg", "uploadFiles/desktop.jpg"]
def fileParameters = ["FrontsideImage", "BacksideImage"]
def files = []
for (i = 0; i < filePath.size(); i++) {
files += new HTTPFileArg (filePath[i], fileParameters[i],
URLConnection.guessContentTypeFromName(new File(filePath[i]).getName()))
}
sampler.HTTPFiles = files
I was curious to see how URLConnection.guessContentTypeFromName() method
actually works. I renamed .jpg extension to .png and image/png is generated
so I guess that it scans extension rather than file hex signature.
Regards,
Nikola
