Xbox live login fails

[gioiann]

panic: error obtaining Live token: error decoding flowtoken XML container: EOF

This error started happening really often, then it went away and now it seems like it happens everytime.

I tried with different accounts and also different IPs in case Microsoft blocked my IP because of suspicious login attempts.
I also tried creating a new account using a new residential IP and then use the same IP to login with gophertunnel API, it's not working, same error but I'm able to login using minecraft

Had some reports of this. Probably some Microsoft account login changes. I'll fix it when I get the time.

I would like to help but there are is no documentation from Microsoft about the Minecraft login flow. I tried using an https proxy but apparently Minecraft doesn't trust the proxy CA. How did you do it?

[Sandertv]

There's some libraries in other languages that implement Microsoft account logins: Looking into those would be worth it.

[gioiann]

Can you give me an hint about where to start? Like, what libraries are you talking about? I don't think there is a library implementing LoginPacket signing. The only way would be reverse engineering Minecraft or an https proxy

The only thing that needs to be done is to login to a Live/Microsoft account and obtain an access token and a refresh token. The rest will still function just fine. Basically, the code in auth/live.go needs to be replaced.

[Sandertv]

This part has nothing to do with Minecraft yet.

I found the problem: parseJSObject() doesn't properly parse the data. There are closing curly brackets before the end of the object properties.

[gioiann]

Not only that, there are different things wrong with parseJSObject() like:

• There can be commas in the value
• " is not trimmed, only ' is

[Sandertv]

The parseJSObject is a terrible hack that was only there as some kind of hack. The login sequence in live.go is quite the hack.

[gioiann]

Should I open a PR ?
