Cannot connect with mopidy.

[Alexander Lyashuk]

When I tried to connect to the server from mopidy-subidy, supysonic seems to return HTTP status 400 to all requests:

2a02:(redacted ipv6 address):4303 - - [05/May/2020 18:53:23] "POST /rest/getArtists.view HTTP/1.1" 400 -
2a02:(redacted ipv6 address):4303 - - [05/May/2020 18:53:23] "POST /rest/getArtists.view HTTP/1.1" 400 -
...
2a02:(redacted ipv6 address):4303 - - [05/May/2020 18:58:10] "POST /rest/ping.view HTTP/1.1" 400 -

I tried to set this in my config

[webapp]
log_file = /tmp/supysonic.log
log_level = DEBUG

The log file is created, but it is completely empty.

I'm able to access the supysonic web UI with my browser.

Version of supysonic is from github master as of yesterday.

Same issue occurs whether I run it through uUWSGI or as a command line debug server.
Could you give me a hint how to debug this further? I can put debug prints into random parts of the code if that helps.

Thanks!

Seems that BadRequestKeyError happens, whatever it means.
That's just the POST /rest/ping.view HTTP/1.1 request.

It expects p parameter for rest/ping.view request.

Hello.

This is due to missing authentication. Supysonic doesn't support the token-based auth introduced with the version 1.13.0 of the Subsonic API. As such you'll have to set legacy_auth to true in you subidy configuration.

[Alexander Lyashuk]

Thanks for your response, that indeed works!

I'm closing the issue as it's resolved for me. However I'd recommend to print an appropriate error message somewhere in logs/etc to save other people from trying to debug this.
