How would you do a request to Facebook object graph to get the user's friends?
If you type in the url it works in the browser (replaced by valid user_id and access token):
"https://graph.facebook.com/user_id/friends?access_token=2227470867|2.AQDi3TbqnqrsPa0_.360"
When I try it from ruby code using Net::HTTP.get_response(URI.parse('url')) I get URI::InvalidURIError error message.
Your access token has some characters that are invalid for a URL. You have to CGI.escape them.
require 'cgi'
access_token = '2227470867|2.AQDi3TbqnqrsPa0_.360'
url = "https://graph.facebook.com/user_id/friends?access_token=#{CGI.escape(access_token)}"
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Get.new(uri.path + "?" + uri.query)
response = http.request(request)
data = response.body
Maybe something to do with OAuth? I'd suggest you to use a library like Koala instead of unrolling custom adhoc solutions.

I am using net-http-persistent gem to fetch pages. It works perfectly fine for most of the cases. But, recently I noted that it returns 401 for urls prefixed with username:password# e.g. https://username:password#somesite.com. If i try other options like excon/curl they fetch such pages without problem. I saw the logs of the requests made by Net::HTTP::Persistent and found out net::http totally discards the username:password part while connecting to the server.
Can anybody help me how to make Net::HTTP::Persistent make use of username:password# part.
----------------------EDITED--------------------
Sample code:
url = "https://user:pass#example.com/feed"
uri = URI(url)
http = Net::HTTP::Persistent.new
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
response = http.request uri
http.shutdown
response.code # yields 401 which it should not as url has username and password.
#Incase of excon, if you do
response = Excon.get(url)
response.status # yields 200 as it is making use of username:password prefix
Based on this issue, try code like:
uri = URI("https://example.com/feed")
req = Net::HTTP::Get.new(uri.request_uri)
req.basic_auth 'user', 'pass'
http = Net::HTTP::Persistent.new
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
response = http.request uri, req
http.shutdown
puts response.code
I am trying to do a multipart post with parameters in ruby securely using https. All the examples I have seen are only http without parameters in addition to the file. However, I can't seem to modify them to get them to work with https and additional parameters (or find documentation showing a good example). How can I do a multipart POST using HTTPS in ruby with parameters? I have tried modify the code from Nick Sieger as shown below but to no avail. Where do I add parameters that I need to pass in in JSON format in addition to the file?
# push file to rest service
url = URI.parse('https://some.url.test/rs/test')
File.open(tm.created_file_name) do |txt|
req = Net::HTTP::Post::Multipart.new url.path,
'file' => UploadIO.new(txt, 'text/plain', tm.created_file_name)
n = Net::HTTP.new(url.host, url.port)
n.use_ssl = true
p req.body_stream
res = n.start do |http|
response = http.request(req)
p response.body
end
end
I figured out to do a multipart form post using https and parameters. Here is the code:
require 'rest-client'
url = 'https://some.url/rs/FileUploadForm'
#res = RestClient.post url, {:multipart=>true,:tieBreakerOptions=>1,
:myFileName=>'file.txt',
:myFile=>File.new('data/file.txt','r')}
response = JSON.parse(#res)
I'm simply trying to get a response from the API that includes certain fields that I'm specifying in my uri string but I keep receiving an InvalidURIError. I've come here as a last resort, having spent hours trying to debug this.
I've already tried using the URI.encode() method on it as well, but only get the same error.
Here's my code:
url = params[:url]
uri = URI('https://graph.facebook.com/v2.3/?id=' + url + '&fields=share,og_object{id,url,engagement}&access_token=' + CONFIG['fb_access_token'])
req = Net::HTTP::Post.new(uri.path)
req.set_form_data('fields' => 'og_object[engagement]','access_token' => CONFIG['fb_access_token'])
res = Net::HTTP.new(uri.host, uri.port)
res.verify_mode = OpenSSL::SSL::VERIFY_NONE
res.use_ssl = true
response = nil
res.start do |http|
response = http.request(req)
end
response = http.request(req)
output = ""
output << "#{response.body} <br />"
return output
And the error I'm receiving:
URI::InvalidURIError - bad URI(is not URI?): https://graph.facebook.com/v2.3/?id=http://www.wikipedia.org&fields=share,og_object{id,url,engagement}&access_token=960606020650536|eJC0PoCARFaqKZWZHdwN5ogkhfs
I'm just exhausted at this point so if I left out any important information just let me know and I'll respond with it as soon as I can. Thank you!
The problem is you're just dumping strings into your URI without escaping them first.
Since you're using Sinatra you can use Rack::Utils.build_query to construct your URI's query component with the values correctly escaped:
uri = URI('https://graph.facebook.com/v2.3/')
uri.query = Rack::Utils.build_query(
id: url,
fields: 'share,og_object{id,url,engagement}',
access_token: CONFIG['fb_access_token']
)
I have the following method in our Ruby 1.8.7 project:
def self.ping_server
request_data = get_request_data
uri = 'another_server.our_company.com'
https = Net::HTTP.new(uri)
https.use_ssl = true
path = "/our_service"
data = request_data.to_json
response = https.post(path, data, {'Content-Type' => 'application/json'})
return response
end
Whenever I run this method, I get the following time out error:
Completed 500 Internal Server Error in 128936ms
Errno::ETIMEDOUT (Connection timed out - connect(2)):
lib/my_class.rb:51:in `ping_our_server'
I checked with a coworker who has access to the logs for another_server.our_company.com. My request isn't arriving at the other server.
What should I do to get my request to work?
EDIT: On further inspection, this is what I think is happening (but I'm not completely sure): Our other server will only accept HTTPS requests, but it looks like my request is being sent over HTTP for some reason. Is there something I need to add to make sure my request is sent over HTTPS?
According to this website, this is how you send an HTTPS request:
require "net/https"
require "uri"
uri = URI.parse("https://secure.com/")
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)
response.body
response.status
response["header-here"] # All headers are lowercase
According to this website (which is linked from my first link), you should also do this to close up a vulnerability in the net/https library:
To get going, you need a local CA certificates bundle, the official
curl site maintains an up to date cacert.pem / ca-bundle.crt file
containing all of the major certificates if you need one.
Next, after a gem install always_verify_ssl_certificates, you can be
up and running with a test as simply as:
require 'always_verify_ssl_certificates'
AlwaysVerifySSLCertificates.ca_file = "/path/path/path/cacert.pem"
http= Net::HTTP.new('https://some.ssl.site', 443)
http.use_ssl = true
req = Net::HTTP::Get.new('/')
response = http.request(req)
If the site
has a bad certificate an error will be raised at this point. If not, a
legitimate HTTP response object will be returned.
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
