Hello guys,
I''m newbie in ruby and Mechanize. I has created a script to make a POST
and GET HTTP request to Redmine application. So, everything fine with
GET request and authorization. But when I try to do a POST request
Mechanize gave a following error:
ws-moonshiner# ruby post.rb
/usr/local/lib/ruby/gems/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:464:in
`post_form'': 500 => Net::HTTPInternalServerError
(Mechanize::ResponseCodeError)
from
/usr/local/lib/ruby/gems/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:357:in
`post''
from post.rb:21
Here is my script:
require ''rubygems''
require ''mechanize''
require ''logger''
# runnig a Mechanize
agent = Mechanize.new { |a| a.user_agent_alias = ''Mac Safari''}
agent.log = Logger.new(STDOUT)
# get the Redmine login form & fill it out with the username/password
page = agent.get("http://127.0.0.1/login")
login_form = page.form_with(:action => "/login")
login_form.username = ''test''
login_form.password = ''test''
# submit Redmine login form
page = agent.submit login_form
issues_page = agent.get("http://127.0.0.1/projects/test/issues")
agent.post(issues_page, {
"priority_id" => "3",
''tracker_id'' => "1",
})
Latest message from logger:
[...]
I, [2010-10-20T13:56:00.340095 #16626] INFO -- : status: 500
I understand that for some reason server generates an internal error.
But I have no idea how to fix it. Does anybody know how to resolve this
issue?
Thank you very much in advance.

Hi, That looks like an error from the webserver side - http://127.0.0.1/login - not a mechanize issue. Probably worth looking in your server logs...

To elaborate a little (since I found this out the hard way)... Mechanize only handles HTTP response codes 200 and 302 - others will throw an exception. So what you''re seeing is, as Chris notes, an error on the server side which returns an HTTP 500, which then throws an exception, which isn''t handled and causes the result you''re seeing. Two things you might want to try: 1. Wrap the post in a begin/rescue block so you can handle the exception 2. Use a packet sniffer to analyze the difference between the post request you''re sending through Mechanize and what a browser sends when you submit the form. The server is likely returning 500 due to a malformed request.
