Read HTML code from HTTPS url

[NicolaRE77]

Hello everyone, is it possible to read the HTML content code of a web page that has an url in HTTPS without using IWEBBROWSER2 ??

For example with ActiveX .NET?
Thank you

Use the HTTP client found in the  "Data Communication" -> "Protocols" palette.

You'd probably need a lot more code (from the Security palette) then that to set up the SSL connection. AFAIK, SSL+HTTP=HTTPS.

I've used stunnel in the past, so the problem doesn't need to be solved in LabVIEW anymore. Stunnel will route the shhtp data to http data.

Worked fine for me visiting the HTTPS of amazon.com. Body contained the full HTML/Javacript.

The header did include the HSTS request, but at that point I already had the body.

If you try to visit the HTTP version, it only returns a 301 permanent redirect header (pointing to the HTTPS version) and no Body.

Hi deceased, I tried with the example above (http post) but it does not work, the html code returned in the body is encoded and therefore illegible.

 url : https://www.amazon.com

OK, thanks for the reply :), would you have an example code?

Not really. I actually have no idea how that would work from LabVIEW. I saw that the HTTP interface has SSL options, but I have no idea what should be wired to what VI...

When I used stunnel, my application actually was the HTTP server. I used .NET for that, and figured I'd better outsource the SSL part.

ok, I think there is this, but where do I find all these certificates and api key?
Is not the client_certificate alone enough?

Is it possible that no one has exploited an HTTP + SSL communication? SOS

Nope. The HTTP VIs do unlike what their name might suggest, also support the HTTPS protocol. As long as you try to connect to a HTTPS server with valid certificate signed by one of the well known certification authorities, they should simply work. If you try to access a server with self signed certificate you have to setup your own certification store with the correct certificate which the HTTP VIs only expose a very simple and not always workable method for.
