mechanize: 400 Bad Request

Axel · Nov 5, 2006

Hello,

when trying to access a certain HTML-frame, I get:
"in `request': Unhandled response (WWW::Mechanize::ResponseCodeError)"

and the page returns: "400 Bad Request"

* Why?
* How to solve this?

With browser, it works.

Thank you for any help!

Hi Axel,

Can you turning on logging, and forward that to the mechanize mailing
list? The URL in the frame may be getting clobbered, but I can't tell
without looking at the logs.

http://rubyforge.org/mail/?group_id=1453

You also may want to get LiveHTTPHeaders for FireFox and compare the
output of that to your mechanize logs.

With browser, it works.

Thank you for any help!

I'll try it this evening (because it is a private job). Logging is done
like this, right?:

require 'logger'
agent = WWW::Mechanize.new {|a| a.log = Logger.new(STDERR) }

Yes, I'll send the results to the mailing list.

You also may want to get LiveHTTPHeaders for FireFox and compare the
output of that to your mechanize logs.

Interesting, did not know about this; that will be my second step.

That is correct, or you can have it go to a file:
agent = WWW::Mechanize.new {|a| a.log = Logger.new("some_file.txt") }
