SSL requests failing

In my test script I have these options

var options = {
      host:   'badssl.com', 
      port:   443,    
      path:   '/',   
      method: 'GET', 
      protocol: 'https:',
    };

and this code after the definition.

var req = require("http").request(options, function(res) {
    res.on('data', function(data) {
      console.log(res);
      console.log("HTTP> "+data);
    });
    res.on('close', function(data) {
      console.log(res);
      console.log("Connection closed");
    });
  });

However, I keep getting a code 400 reply "The plain HTTP request was sent to HTTPS port". There are no redirects at the server end and I have tested the same functionality with my own server, address http://www.xdb.fi/dummy.txt - with the same result.

The script seems to be using http, despite all my attempts to switch to https. Do I have two blind eyes? I have one semi-blind already :)

Oh, I see, after finding the information accidentally: Hardly any boards can use HTTPS requests. I wish this fact had been written onto the http.request documentation. Now the information can only be found here: https://www.espruino.com/Internet#https and nowhere else.

Well, I experienced a moment of re-evaluation at this point. In private (unsecure) projects, I think http may work, though.

Anyhow, after such a good start I had, this was somewhat disappointing.

The ESP8266 is so limited that it's definitly not possible. ESP32 can do after deactivate of BLE or if you use a board with PSRAM

Well, for this project, the lack of SSL is not the killer. I can definitely do a lot at the remote server end (like limiting the access to an IP range), or possibly add an Nginx/PHP server as a mediator :)

Espruino is somewhat weird, but fun to work with, especially when writing the JS app in TypeScript. It is much move convenient than MicroPython, for instance. I like the event-driven approach.

Dear MaBe,

I would like to know if the psram is "automatically" used by e.g. wrover or if something has to be set when uploading the firmware?

hi, on esp32 it is detected during boot.
