Re: Help with 400 Bad Request

I'm looking now.

The only thing that stands out to me is that ratings are numbers
between 0 and 100. I'm assuming you meant four stars, which would be 80,
not 4.

I'm not sure what exact process/tools you're using for submission since
I'm unfamiliar with C#, but it works fine with me with, at the command
line:

curl --header "Content-Type: application/xml;charset=utf-8" -X POST --digest --user username:password -d @rate.xml http://musicbrainz.org/ws/2/rating?client=ianmcorvidae-0.0.1

where username/password obviously get replaced and rate.xml contains:

<?xml version="1.0" encoding="UTF-8"?>
<metadata xmlns="http://musicbrainz.org/ns/mmd-2.0#">
<recording-list>
<recording id="f5aec1b4-0162-489b-ad1a-2aeecebc7d8a">
<user-rating>80</user-rating>
</recording>
</recording-list>
</metadata>

However, this also works fine with 4 rather than 80, though the result
on the site is that it appears to be unrated, since that's less than 1
star.

Looking at the code, most normal errors should return an XML document
with the error, e.g. if I change 'recording' to 'event' (since events
can't be rated), I get:

<?xml version="1.0" encoding="UTF-8"?><error><text>Entity type 'event'
cannot have ratings. Supported types are: artist, recording, work,
release-group, label</text><text>For usage, please see:
http://musicbrainz.org/development/mmd</text></error>

One thing I might check is how your C# tools handle response bodies for
this sort of request -- perhaps it's throwing out the response that
would tell you what's wrong?

So, I'm not really sure what might be wrong, I guess :( hopefully something in
there helps. One other small thing I notice is that you're giving a
different client in the URL vs. the user-agent, which I'm guessing isn't
intentional.

Hope you find out what's wrong!
