how to use Post to download zip shapefile itself?

[zhengniu]

Thanks for sharing this great tool

I have tried to use Post request in my code to get zipped file download through web client, but no clue how to do it in callback function to fullfil the same ability as the convert button "Convert to Shapefile" does.

Could you please provide newbies some help? Many Thanks
