[Mechanize-users] mechanize: 400 Bad Request

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.

In the logs below, I marked 4 lines with "***", where I see possible  
differences in the URI. But I don''t know, if this is the reason for the
malfuncion and how to fix this.

mechanize:
Net::HTTP::Get:  
https://www.frankfurter-fondsbank.de/../diverse/navigation.jsp;jsessionid=CdEfG!-34567!-7654?menu=1

firefox-LiveHTTPHeaders:
GET /diverse/navigation.jsp;jsessionid=AbCdE!-1234!-5678?menu=1 HTTP/1.1


Thank you for any help!

It looks like mechanize doesn''t support relative paths in links.  This
is a bug, and I''ll look in to fixing it.

Okay, I''m stumped.  I thought this was a bug in Mechanize, but
I''ve
written a few test cases to try to reproduce the error, and I can''t!

Are you sure the following line is being executed?
> >    framePage = agent.click( page2.frames.text(''nav'')
)   # This works not
I copied the html you provided in to a file and tried to reproduce the error,
but mechanize handles the relative link correctly.  Would it be possible for
you to write a short test case that reproduces the error?

[Mechanize-users] mechanize: 400 Bad Request

Hello,

finally, I found time to create a test case:

With browser, the following page shows up correctly:

http://cafriedrich.netfirms.com/root/dir1/firstpage.htm



With the "standard mechanize code", I get the before mentioned error:
----------------------------------------------------------------------

require ''rubygems''
require ''mechanize''
require ''logger''
require ''fileutils''

# ========== CONFIG ==================================@logFilePath =
"G:/Ruby/FrankfurterFondsBank/downloaded/log.txt"
@downloadDir = ''G:/Ruby/FrankfurterFondsBank/downloaded/''
@firstPage = "http://cafriedrich.netfirms.com/root/dir1/firstpage.htm"
# ========== END CONFIG ==============================

FileUtils.mkpath( File.dirname(@logFilePath) )
FileUtils.mkpath( @downloadDir )

agent = WWW::Mechanize.new{|a| a.log = Logger.new(@logFilePath) }

page = agent.get(@firstPage)
txt = page.body
File.open("@downloadDir" + "firstpage.htm",
''w'') {|f|  f.write(txt)  }

puts "\n\n================= frames:=================  "
page.frames.each { |f| puts sprintf("%-15s %-1s \n", f.text, f.href) }
puts "\n=================  /frames =================  \n\n"

begin
   mainframe = agent.click( page.frames.text(''main'') )
   txt = mainframe.body
   File.open(@downloadDir + "mainframe.htm", ''w'')
{|f|  f.write(txt)  }

   frameleft1 = agent.click( page.frames.text(''left1'') )
   txt = page.body
   File.open(@downloadDir + "left1.htm", ''w'') {|f| 
f.write(txt)  }
rescue WWW::Mechanize::ResponseCodeError => ex
   puts "====== ERROR =========="
   puts ex.page.body
   puts "====== /ERROR =========="
end

puts "-- Exiting now."



With the "workaround code" below, it works:
-------------------------------------------

require ''rubygems''
require ''mechanize''
require ''logger''
require ''fileutils''

# ========== CONFIG ==================================@logFilePath =

# ========== END CONFIG ==============================

FileUtils.mkpath( File.dirname(@logFilePath) )
FileUtils.mkpath( @downloadDir )

agent = WWW::Mechanize.new{|a| a.log = Logger.new(@logFilePath) }

page = agent.get(@firstPage)
txt = page.body
File.open("@downloadDir" + "firstpage.htm",
''w'') {|f|  f.write(txt)  }

puts "\n\n================= frames:=================  "
page.frames.each { |f| puts sprintf("%-15s %-1s \n", f.text, f.href) }
puts "\n=================  /frames =================  \n\n"

begin
   mainframe = agent.click( page.frames.text(''main'') )
   txt = mainframe.body
   File.open(@downloadDir + "mainframe.htm", ''w'')
{|f|  f.write(txt)  }

   href = ''http://cafriedrich.netfirms.com/root/''        #

   href <<
page.frames.text(''left1'').href.sub(''../'',
'''') # <-  WORKAROUND
   frameleft1 = agent.get(href)                          # <-  WORKAROUND
   txt = page.body
   File.open(@downloadDir + "left1.htm", ''w'') {|f|

rescue WWW::Mechanize::ResponseCodeError => ex
   puts "====== ERROR =========="
   puts ex.page.body
   puts "====== /ERROR =========="
end

Thank you!  I understand the bug now.  When mechanize sees that the url
is relative, it looks at the last url in its history to determine where
to go next.  In the case of frames, that is not correct, since your
request flow is not linear.  I''ll fix this issue for the next release.

Here''s my workaround where the rescue block never gets called:

  require ''rubygems''
  require ''mechanize''
  
  # ========== CONFIG ==================================  @firstPage =
"http://cafriedrich.netfirms.com/root/dir1/firstpage.htm"
  # ========== END CONFIG ==============================  
  agent = WWW::Mechanize.new
  page = agent.get(@firstPage)
  
  begin
     mainframe = agent.click( page.frames.text(''main'') )
     agent.history.pop  # <= This makes it work!
     frameleft1 = agent.click( page.frames.text(''left1'') )
  rescue WWW::Mechanize::ResponseCodeError => ex
     puts "Error"
  end
  
  puts "-- Exiting now."
