This is not really a J question, but has anyone successfully figured out how to download something using https protocol? It's actually more complicated than this. If I want to get, say, the price and volume history for Tesla from Yahoo Finance, the "Download" command there generates a string like this: https://query1.finance.yahoo.com/v7/finance/download/TSLA?period1=1277769600&period2=1609718400&interval=1d&events=history&includeAdjustedClose=true
I used to be able to take this string and substitute into it to download not only prices for TSLA but any other stock on Yahoo Finance for which I knew the ticker. Now this sort of thing fails when I use my former method which was just invoking "wget" via the "shell" command in J. Instead I get an 800+ byte html file with error messages. I think the switch to https from http is to blame but having a query string instead of a filename may also be an issue. The "wget" method still works for http files like this (to get the famous iris data): shell 'wget -O iris.data http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data'. So, I suspect it's probably https that is to blame but I do not have a working example of submitting a query string using http so I cannot be completely sure other than I think this used to work. Any suggestions for an automatable way to do this would be welcome.
