Tinode token malformed error when decoded by php

[Ons Ta]

I can not understand what I am doing wrong.

When I take a token from Tindroid, then base64 decode it with php, in some cases I can not login with GRPC - Tinode returns malformed error.

For example.

<?php

$token = ' 3X3jPTdOIYdz24hkFAABAAEAIAzgCv1K7A/0LKspbEAvK6vjZHPjSYk3IGd eyzbkQ8'; //a token from Tindroid

$token = base64_decode($token);

echo $token;

?>

Echo produces:

Ý}ã=7N!‡sÛˆd à
ýJì ô,«)l@/+«ãdsãI‰7 g^Ë6äC

As you can see, there is a newline. Do tokens contain newlines. As I understand, malformed error appears when a token after decoding contains a newline.

How to resolve this problem? Thanks.

It's most likely a problem with URL decoding/encoding. The '+' is converted to space.
