here's my problem:
I need to post data from RoR server to remote PHP server, to a specific url, but before that I need to authenticate.. any help is much appreciated..
What I have done so far..
#sample data
postparams ={'id'=>1, 'name'=>'Test', 'phone'=>'123123123'}
#url - is in form http://domain.com/some/somemore
#user - contains username
#pass - contains password
require "uri"
require "net/http"
uri = URI(url)
req = Net::HTTP::Post.new(uri.path)
req.set_form_data(postparams)
res = Net::HTTP.start(uri.hostname, uri.port) do |http|
http.request(req)
end
case res
when Net::HTTPSuccess, Net::HTTPRedirection
#all ok
else
res.value
end
Obviously I get 403.. because I'm not authorized? How do I authorize?
I also tried my luck with mechanize gem (below - using the same "sample" data\vars)
#when not logged in it renders login form
login_form = agent.get(url).forms.first
login_form.username = user
login_form.password = pass
# submit login form
agent.submit(login_form, login_form.buttons.first)
#not sure how to submit to url..
#note that accessing url will not render the from
#(I can't access it as I did with login form) - I simply need to post postparams
#to this url... and get the response code..
I think the mechanize gem is your best choice.
Here is an example showing how to post a file to flicker using mechanize.
Maybe you could easily adapt to your needs:
require 'rubygems'
require 'mechanize'
abort "#{$0} login passwd filename" if (ARGV.size != 3)
a = Mechanize.new { |agent|
# Flickr refreshes after login
agent.follow_meta_refresh = true
}
a.get('http://flickr.com/') do |home_page|
signin_page = a.click(home_page.link_with(:text => /Sign In/))
my_page = signin_page.form_with(:name => 'login_form') do |form|
form.login = ARGV[0]
form.passwd = ARGV[1]
end.submit
# Click the upload link
upload_page = a.click(my_page.link_with(:text => /Upload/))
# We want the basic upload page.
upload_page = a.click(upload_page.link_with(:text => /basic Uploader/))
# Upload the file
upload_page.form_with(:method => 'POST') do |upload_form|
upload_form.file_uploads.first.file_name = ARGV[2]
end.submit
end
I strongly suggest the use of ruby rest-client gem.

I'm building out a platform for displaying data in charts that pulls from Zendesk's API. I'm running into trouble in that only 100 records at a time can be pulled with one call. How do I pull multiple pages of records from this resource?
Here is the code I use to make the call:
require 'net/http'
require 'uri'
require 'json'
#imports User data from the zendesk api and populates the database with it.
uri = URI.parse("https://samplesupport.zendesk.com/api/v2/users.json")
request = Net::HTTP::Get.new(uri)
request.content_type = "application/json"
request.basic_auth("sampleguy#sample.com", "samplepass")
req_options = {
use_ssl: uri.scheme == "https",
}
#response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
http.request(request)
end
puts #response.body
puts #response.message
puts #response.code
This works fine for calling down one 'page' of resources...any help with grabbing multiple pages using my script would be greatly appreciated. Thank you!
Based on ZenDesk's documentation they return a next_page attribute in their payload. So you should just check for its existence and then query again if it exists. Repeat as needed.
require 'json'
# setup to query for the first page
results = JSON.parse(#response.body)
users = results['users'] #to get the users
if results['next_page']
# Do another query to results['next_page'] URL and add to users list
On a URL is accessible a file that I want to download. The problem is, that I can access this file on a URL only when I am logged in to the service.
How to download a file from a URL that is protected by login (I have the credentials)? In PHP would be maybe to do it with using cURL, how to do that in Ruby?
Thanks
Read HTTP basic authentification docs: http://ruby-doc.org/stdlib-2.0.0/libdoc/net/http/rdoc/Net/HTTP.html#label-Basic+Authentication
uri = URI('http://example.com/index.html?key=value')
req = Net::HTTP::Get.new(uri)
req.basic_auth 'user', 'pass'
res = Net::HTTP.start(uri.hostname, uri.port) {|http|
http.request(req)
}
puts res.body
If you're looking to get into a site that doesn't just have basic authentication, you should probably look into mechanize. For example (taken from a railscast on the subject), you might do something like this:
require 'mechanize'
agent = WWW::Mechanize.new
agent.get("http://railscasts.tadalist.com/session/new")
form = agent.page.forms.first
form.password = "secret"
form.submit
agent.page.link_with(:text => "Wish List").click
I'm trying to register new achievement on Facebook using RoR 3.2.8,
here is what my controller's action looks like
require 'net/http'
require 'uri'
...
def create
# achievement url
#url = "http://smth.herokuapp.com/achievements/fb/ach.html"
# fb graph api url
#fbcall = "https://graph.facebook.com/#{FB_APP_ID}/achievements"
uri = URI(#fbcall)
res = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https', :verify_mode => OpenSSL::SSL::VERIFY_PEER) do |http|
req = Net::HTTP::Post.new(uri.path)
req.set_form_data('access_token' => FB_APPLICATION_TOKEN, 'achievement' => #url, 'display_order' => '5')
response = http.request req
end
#ans = res.body.to_s()
end
I get the following #ans each time
{"error":{"message":"(#3502) Object at achievement URL is not of type game.achievement","type":"OAuthException","code":3502}}
However achievement html at #url has
<meta property="og:type" content="game.achievement" />
property in it.
If I put this html to Facebook debugger it does not show any errors and recognizes type as game.achievement.
If I write HTML form with inputs which makes auto-submit on load, the achievement is created OK.
So something seems to be wrong with the way I do post request from rails controller.
Any help, please %)
I noticed that if I put achievement #url to facebook debugger first, then it would register corresponding achievement.
So now I do two ajax-requests: first one to facebook debugger and then (after the first is complete) to the facebook graph api.
I'm trying to pull a facebook avatar via auth. Here's what i'm doing:
def image_uri
require 'net/http'
image = URI.parse(params[:image]) # https://graph.facebook.com/565515262/picture
fetch = Net::HTTP.get_response(image)
based = 'data:image/jpg;base64,' << Base64.encode64(fetch)
render :text => based
end
I'm getting the following error (new error — edited):
Connection reset by peer
I've tried googling about, I can't seem to get a solution, any ideas?
I'm basically looking for the exact functioning of PHP's file_get_contents()
Try escaping the URI before parsing:
URI.parse URI.escape(params[:image])
Make sure that params[:image] does contain the uri you want to parse... I would instead pass the userid and interpolate it into the uri.
URI.parse URI.escape("https://graph.facebook.com/#{params[:image]}/picture)"
Does it throw the same error when you use a static string "https://graph.facebook.com/565515262/picture"
What does it say when you do
render :text => params[:image]
If both of the above don't answer your question then please try specifying the use of HTTPS-
uri = URI('https://secure.example.com/some_path?query=string')
Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https').start do |http|
request = Net::HTTP::Get.new uri.request_uri
response = http.request request # Net::HTTPResponse object
end
Presuming you are on ruby < 1.9.3, you will also have to
require 'net/https'
If you are on ruby 1.9.3 you don't have to do anything.
Edit
If you are on the latest version, you can simply do:
open(params[:image]) # http://graph.facebook.com/#{#user.facebook_id}/picture
I'm using Mechanize to extract the links from the page.
To ease with development, I'm using fakeweb to do superfast response to get less waiting and annoying with every code run.
tags_url = "http://website.com/tags/"
FakeWeb.register_uri(:get, tags_url, :body => "tags.txt")
agent = WWW::Mechanize.new
page = agent.get(tags_url)
page.links.each do |link|
puts link.text.strip
end
When I run the above code, it says:
nokogiri_test.rb:33: undefined method `links' for #<WWW::Mechanize::File:0x9a886e0> (NoMethodError)
After inspecting the class of the page object
puts page.class # => File
If I don't fake out the tags_url, it works since the page class is now Page
puts page.class # => Page
So, how can I use the fakeweb with mechanize to return Page instead of File object?
Use FakeWeb to replay a prefetched HTTP request:
tags_url = "http://website.com/tags/"
request = `curl -is #{tags_url}`
FakeWeb.register_uri(:get, tags_url, :response => request)
agent = WWW::Mechanize.new
page = agent.get(tags_url)
page.links.each do |link|
puts link.text.strip
end
Calling curl with the -i flag will include headers in the response.
You can easily fix that adding the option :content_type => "text/html" you your FakeWeb.register_uri call
