Setting HTTP Headers

Ruby
1

Hi All

I’ve read the Pickaxe and the Ruby Docs but for the life of me I can’t
figure out an easy way of setting the headers of my HTTP
request/connection. I see a class called HTTPHeader and I see some
methods
have an “initheader” parameter but I was expecting there to be a simple
way
of ‘adding’ headers at any point in the script. Possible switching them
and
replacing with other values.

Does anyone know of a way?

Many thanks for your help.

“By adding headers at any point in the script?” Just to be sure, we talk
about http?

I think its not that problem to hack somethink like you want. But if
in pure ruby, just do it yourself :slight_smile:

Many thanks for your help.

The reason ESP, for example, is not considered a viable topic in
contemoprary
psychology is simply that its investigation has not proven
fruitful…After
more than 70 years of study, there still does not exist one example of
an ESP
phenomenon that is replicable under controlled conditions. This simple
but
basic scientific criterion has not been met despite dozens of studies
conducted
over many decades…It is for this reason alone that the topic is now of
little
interest to psychology…In short, there is no demonstrated phenomenon
that
needs explanation.

There’s an example for setting headers using open-uri in the ruby docs:
http://ruby.outertrack.com/file/ruby-1.8.4%2Flib%2Fopen-uri.rb

open(“Ruby Programming Language”,
“User-Agent” => “Ruby/#{RUBY_VERSION}”,
“From” => “[email protected]”,
“Referer” => “http://www.ruby-lang.org/”) {|f|
…
}

If you’re using Net:HTTP directly, initheader is a hash of header
values. It’s
really not documented too well there. Unless you feel you need to use
Net:HTTP, I recommend you use open-uri instead, it does a lot more work
for
you. I’m not sure what you mean by the last part of your question, but
you
can certainly store your hash in a variable and modify it during your
script’s execution as necessary.

Many thanks for your help.
I hope I’ve gone some way to answering your question.

Can open-uri do POSTs? I am pretty sure the answer is no but I would like a
definitive answer from someone who is very familiar with open-uri.

Documentation may be lacking in some areas, but you can rely on RDoc to
at
least generate a list of all public methods. I’m afraid OpenURI is
read-only “for the moment”

Wanting to do POST requests might be a good reason to use Net:HTTP open
open-uri :slight_smile:
