I wanted to check facebook status of another page from ruby script. First of all is it possible. I have been doing the following:
I got developer account
I got app key and secret
I installed json_pure gem
Here is my code:
require 'rubygems'
require 'json/pure'
require 'net/http'
url ="https://graph.facebook.com/user_id/feed?access_token=app_id|app_secret"
uri = URI.parse(URI.encode(url.strip))
#to remove specia codes encode
#to remoce whitespace strip
req = Net::HTTP::Get.new(uri.to_s)
res = Net::HTTP.start(uri.host, uri.port) {|http|
http.request(req)
}
html = res.body
res = JSON.parse(html)
Here is the error:
C:/Ruby187/lib/ruby/1.8/net/protocol.rb:135:in `sysread': An existing connection
was forcibly closed by the remote host. (Errno::ECONNRESET)
I would recommend using the koala gem instead of Net::Http
#graph = Koala::Facebook::API.new(oauth_access_token)
status = #graph.get_connections("me", user_id, "status")

Writing extensions for Sketchup I need to get around their usage of their own ruby (2.0.0) interpreter. Most importantly, I can't install gems that require build tools.
How can I send a file per POST request to my local server which does some calculations and answers with a JSON object?
I'm aware how I can use rest-client to send the file, but due the mentioned restrictions I can't use it (it required build tools). Is there another comparable way or library that can help me?
require 'uri'
url = 'http://foourl.com'
uri = URI.parse(url)
data = File.read('fil_path')
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
request.body = data
request.content_type = 'audio/amr'
response = http.request(request)
(Taken from here)
Don't forget to configure your content type
You can use Ruby's native Net::HTTP library.
Examples:
require 'net/http'
require 'uri'
uri = URI('http://www.example.com/search.cgi')
res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
puts res.body
or
response = http.post('/cgi-bin/search.rb', 'query=foo')
I am reading through the documentation of the socksify gem on Rubyforge. I have installed the gem successfully, and I have run this documented code with success to test that my local implementation can replicate it:
require 'socksify/http'
uri = URI.parse('http://rubyforge.org/')
Net::HTTP.SOCKSProxy('127.0.0.1', 9050).start(uri.host, uri.port) do |http|
http.get(uri.path)
end
# => #<Net::HTTPOK 200 OK readbody=true>
But how do I e.g. scrape 'http://google.com/', and get the html content? I wish to parse it with e.g. Nokogiri like this:
Nokogiri::HTML(open("http://google.com/))
require 'socksify/http'
http = Net::HTTP::SOCKSProxy(addr, port)
html = http.get(URI('http://google.de'))
html_doc = Nokogiri::HTML(html)
I am doing my best to get JSON back from the instagram API. Here is the code I am trying in my rake task within rails.
require 'net/http'
url = "https://api.instagram.com/v1/tags/snow/media/recent?access_token=522219.f59def8.95be7b2656ec42c08bff8a159a43d06f"
resp = Net::HTTP.get_response(URI.parse(url))
puts resp.body
All I end up with in the terminal is "rake aborted!
end of file reached"
If you look at the instagram docs http://instagram.com/developer/endpoints/tags/ and you paste the following URL in your browser you will get JSON back so I'm sure I am doing something wrong.
https://api.instagram.com/v1/tags/snow/media/recent?access_token=522219.f59def8.95be7b2656ec42c08bff8a159a43d06f
It has to do with HTTPS url you need to modify your code to include SSL
require "net/https"
require "uri"
uri = URI.parse("https://api.instagram.com/v1/tags/snow/media/recent?access_token=522219.f59def8.95be7b2656ec42c08bff8a159a43d06f")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
puts response.body
alternatively you could use somthing like https://github.com/jnunemaker/httparty to consume 3rd party services
Looks like you'd need to configure net/http to use SSL because you're using https.
Alternative : use this with Rails, it'll parse the json on the fly too :
ActiveSupport::JSON.decode(open(URI.encode(url)))
Returns a hash to play with
I want to do a XMLHttpRequest POST in Ruby. I don't want to use a framework like Watir. Something like Mechanize or Scrubyt would be fine. How can I do this?
Mechanize:
require 'mechanize'
agent = Mechanize.new
agent.post 'http://www.example.com/', :foo => 'bar'
Example with 'net/http', (ruby 1.9.3):
You only have to put an additional header for the XMLHttpRequest to your POST-request (see below).
require 'net/http'
require 'uri' # convenient for using parts of an URI
uri = URI.parse('http://server.com/path/to/resource')
# create a Net::HTTP object (the client with details of the server):
http_client = Net::HTTP.new(uri.host, uri.port)
# create a POST-object for the request:
your_post = Net::HTTP::Post.new(uri.path)
# the content (body) of your post-request:
your_post.body = 'your content'
# the headers for your post-request (you have to analyze before,
# which headers are mandatory for your request); for example:
your_post['Content-Type'] = 'put here the content-type'
your_post['Content-Length'] = your_post.body.size.to_s
# ...
# for an XMLHttpRequest you need (for example?) such header:
your_post['X-Requested-With'] = 'XMLHttpRequest'
# send the request to the server:
response = http_client.request(your_post)
# the body of the response:
puts response.body
XMLHTTPRequest is a browser concept, but since you're asking about Ruby, I assume all you want to do is simulate such a request from a ruby script? To that end, there's a gem called HTTParty which is very easy to use.
Here's a simple example (assuming you have the gem - install it with gem install httparty):
require 'httparty'
response = HTTParty.get('http://twitter.com/statuses/public_timeline.json')
puts response.body, response.code, response.message, response.headers.inspect
Excuse the tabs. I'm trying to download a file from remote to local and I keep getting one back that is exactly 310 bytes (regardless of what file I choose to download). I tried setting the timeout to 0, but this isn't working. What am I doing wrong? Thanks!
#downloadUrl = 'https://username:password#api.net'
Net::HTTP.start(#downloadUrl) do |http|
response = http.get('/file.ext')
open('/Users/me/file.ext', "wb", :read_timeout=>0) do |file|
file.write(response.body)
end
end
EDIT: I don't want to use httpclient, I want to use standard net/http. I am almost there, but I keep getting initialize': getaddrinfo: nodename nor servname provided, or not known (SocketError) thrown at Net::HTTP.start(url.path). But when I remote "https", I get ECONNREFUSED. ...Getting closer?
url = URI.parse('https://api.net/file.ext')
#request = Net::HTTP.start(url.path)
#request.basic_auth 'username', 'password'
sock = Net::HTTP.new(url.host, 443)
sock.use_ssl = true
sock.ssl_version='SSLv3'
sock.start do |http|
response = http.get(#request)
open('/Users/me/file.ext', "wb", :read_timeout=>0) do |file|
file.write(response.body)
end
end
Using httpclient is much simpler when accessing via SSL.
gem install httpclient
I haven't tried this out, but this should work for you. Here is the rdoc.
require 'httpclient'
domain = "https://api.net/file.ext"
username = "username"
password = "password"
clnt = HTTPClient.new
clnt.set_auth(domain, username, password)
res = clnt.get_content(https_url)
You can refer to the "writing a binary file in ruby" question for saving your response to a file.
Updated Using net/http
You should be doing Net::HTTP.start(url.host, url.port) instead of Net:HTTP.start(url.path). See RDoc for Net::HTTP.start.
url = URI.parse("https://api.net/file.ext")
download_file = opne("/Users/me/file.ext", "wb")
request = Net::HTTP.start(url.host, url.port)
# .. set basic auth, verify peer etc
begin
request.request_get(url.path) do |resp|
resp.read_body { |segment| download_file.write(segment) }
end
ensure
download_file.close
end
