Stop httpServer

Hello,

Is there an event to turn off an http server?

var server=http.createServer(...)

This doesn't seem to work even though it looks documented (httpSrv class):

server.close();

Any help is appreciated. Thanks.

.close should work - however you might be having troubles if you haven't called server.listen(port) first I guess?

What device are you using?

From your post history it seems like you may be using ESP32, in which case I guess there's a small chance that .close is buggy? I'm pretty sure it's been tested to death on official Espruino boards so I'd be very surprised if there was any trouble on those.

Thanks for the reply Gordon. Yes it's for an ESP32 (ESP-WROOM-32) with Espruino build 1v94. Here's the full example where I get an error.

var http = require('http');

var server=http.createServer(function(req, res){
    res.writeHead(200);
    res.end("Hello World");
    console.log("res sent");
}).listen(80);

setTimeout(function(){
    server.close();
},5000);

And the error message I get

Uncaught Error: Field or method "close" does not already exist, and can't create it on undefined
 at line 1 col 7
server.close();
      ^

The webserver continues to work before and after the error. I tried this on an ESP8226 and get the same error also.

Again, any help is very much appreciated.

Hi @cmo!

I am affraid that listen() returns nothing (unlike the node.js' one). I have submitted a new bug for this.

In the meantime the code would need to look as follows:

var http = require('http');
var server=http.createServer(function(req, res){
        res.writeHead(200);
        res.end("Hello World");
        console.log("res sent");
});
server.listen(80);
setTimeout(function(){
        server.close();
},5000);

It's fixed now.

But PLEASE - there's a massive heading right at the top of the forum. This bit of the forum is for official boards ONLY. There's an ESP32 forum here: http://forum.espruino.com/microcosms/1086/

It may seem petty but I support myself purely off of Espruino board sales - and as a way to convince people to buy my boards I offer support to them on these sections of the forum.

Thank you. I agree, I put this in the wrong forum.
