in reply to LWP not POSTING (400 Bad Request)

Hi HollyWould,

From your example log message, it looks to me like the parameters key, source and format are supposed to be encoded into the URI - whether or not they're also part of the POST body I can't tell, you'd have to take a look at the traffic (e.g. Wireshark) and tell us more about that.

It's been a while since I used raw LWP, so I might be forgetting an easier way, but one way to get those parameters onto the URI is with URI:

# ... use URI; my $uri = URI->new($server_endpoint); $uri->query_form( key => $server_api_key, source => $encoded, format => "json", ); my $req = HTTP::Request->new(POST => $uri); # ...

This gets me the URL query string ...?key=xxxx&source=http%3A%2F%2Fphotos.mysite.com%2F128.jpg&format=json which looks like what you want.

Hope this helps,
-- Hauke D

    Hauke - Bingo! Yes, the web application is expecting the attributes in the URI, not in the POST body. Thanks for your assistance with this, much appreciated. Cheers,HW
