mechanize: 400 Bad Request

Axel

11/5/2006 4:02:00 PM

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!

Axel

agent.get("https://www.frankfurter-fondsbank.de/login/Logon...)

.... login stuff...

begin
framePage = agent.click( page2.frames.text('nav') ) # This works
not
# framePage = agent.click( page2.frames.text('head') ) # This works
rescue WWW::Mechanize::ResponseCodeError => ex
puts ex.page.body

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/?gro...

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

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.

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") }
