HTTP to HTTPS

[julienchastang]

Related to #128. There are many references in the IDV that point to obsolete http URLs. Migrate to https. Document what needs to be updated in this issue.

If possible, it would be best to take the time to make sure whatever code is making the http requests checked the server response to see if there was a http redirect, and if so, checked the location returned in the server response to find the the new location of the resource.

Luckily most of not all of the url access in the IDV goes through a single method IOUtil.getInputStream so making this change shouldn’t be too hard

Awhile back I basically did what Sean and Jeff proposed for McV, though we had to back out of the change for a few reasons (that escape me at the moment). Here's what I had:

https://github.com/Unidata/IDV/compare/master...jon4than:http-redirects?expand=1

I can create a pull request if you'd like.

Jon,

Please create a pull request. Your solution is better.

I'm not sure who all did what but I made a change to IOUtil just now (so I could load some bundles for some drilsdown work) before I saw that its been changed. I'm checking my changes in and overriding the other changes as it seems like just swapping out http for https might not be an effective way to handle redirects as there might be server and/or path changes as well.

Below is the diff

-Jeff

                int response = huc.getResponseCode();
                //Check for redirect
                if (response == HttpURLConnection.HTTP_MOVED_TEMP
                    || response == HttpURLConnection.HTTP_MOVED_PERM
                    || response == HttpURLConnection.HTTP_SEE_OTHER) {
                    String newUrl =

connection.getHeaderField("Location");

                    connection = new URL(newUrl).openConnection();
                    connection.setAllowUserInteraction(true);
                    huc = (HttpURLConnection) connection;
                }

1297,1301d1306 < } else if (huc.getResponseCode() == 301 || huc.getResponseCode() == 302) { < String urlStr = url.toString().replaceFirst("http:", "https:"); < URL newURL = new URL(urlStr); < connection = newURL.openConnection(); < connection.setReadTimeout(30000); //30 sec
