I am having a very hard time getting access to the quickblox API. Based on their documentation this code should work:
require 'base64'
require 'cgi'
require 'openssl'
require 'hmac-sha1'
# Application credentials
aPPLICATION_ID = 12345
aUTH_KEY = 'hidden'
aUTH_SECRET = 'hidden'
# Generate signature
timestamp = Time.now.in_time_zone('UTC').to_i
nonce = timestamp-425346
signature_string = "application_id=#{aPPLICATION_ID}&auth_key=#{aUTH_KEY}&nonce=#{nonce}×tamp=#{timestamp}"
signature =Base64.encode64("#{ OpenSSL::HMAC.digest('sha1', signature_string, aUTH_SECRET) }")
# Post
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
request = Net::HTTP::Post.new("/session.json")
request.add_field('QuickBlox-REST-API-Version', '0.1.1')
request.add_field('Content-Type', 'application/json')
request.add_field('Accept', '*/*')
request.body = {"application_id" => aPPLICATION_ID, "auth_key" => aUTH_KEY, "nonce" => nonce, "timestamp" => timestamp, "signature" => signature }.to_json
response = http.request(request)
However I keep getting an error: {"errors":{"base":["Unexpected signature"]}}
Even when using their hurl: http://hurl.quickblox.com/ i get the exact same error. Very frustrating. What exactly am I doing wrong?
As it turns out, it looks like QuickBlox does not accept the signature has produced by ruby for some reason. QuickBlox even removed their own ruby gem (in which also generates this same error).
Right now the solution is to grab the token via a php script first then do your calls in ruby.
Check my stackoverflow answer on this issue here.
This mostly boils down to these two lines:
signature_string = "application_id=#{aPPLICATION_ID}&auth_key=#{aUTH_KEY}&nonce=#{nonce}×tamp=#{timestamp}"
signature =Base64.encode64("#{ OpenSSL::HMAC.digest('sha1', signature_string, aUTH_SECRET) }")
You can check this quickblox_api gem too. It worked greatly for me.

I have a working request on localhost, which basically calls and endpoint using an address
def stuart_validate_address(address)
require 'uri'
require 'net/http'
### not working with accents like Calàbria
# url = URI("https://api.stuart.com/v2/addresses/validate?type=picking&address=#{address}")
# url = URI.parse("https://api.stuart.com/v2/addresses/validate?type=picking&address=#{address}")
url = URI.parse(URI.escape("https://api.stuart.com/v2/addresses/validate?type=picking&address=#{address}"))
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Get.new(url)
request["authorization"] = "Bearer #{AUTH_TOKEN}"
request.body = "{}"
response = http.request(request)
JSON.parse(response.read_body)
end
If I use the endpoint with Postman it works, if I do the call with localhost it works. But once we are on production (gcloud) it complains about
URI::InvalidURIError
URI must be ascii only "https://api.stuart.com/v2/addresses/validate?type=picking&address=Córsega 494, 08025, Barcelona"
I know I have to parse it and escape it, but I can't figure out why I still have the same error. Also I am curious why it's working on localhost and postman, and not in Rails production environment.
The issue is that you have an acute ó in your url.
If you are using Rails, you can use string#parameterize
Or if plain Ruby, you use i18n gem:
require "i18n"
I18n.transliterate("Olá Mundo!")
=> "Ola Mundo!"
I am trying to perform an HTTP authorization using Ruby on Rails. Here is what I'm trying:
res = http.post(uri.request_uri,
:Authorization => cobSessionToken,
"coBrandSessionCredential=loginToken=#{cobSessionToken}&userLogin=#{login}&userPassword=#{password}")
render :json => {"isValid" => true, "Body" => JSON.parse(res.body)}
This doesn't seem to work. How can I perform an authorization?
how about something like this?
url = URI.parse('https://my.url.com/path')
req = Net::HTTP::Post.new(url.path)
req.basic_auth 'user', 'pass'
req.use_ssl = true
req.form_data({'key1' => 'val1', 'key2' => 'val2'})
resp = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
puts resp
I would recommend using something like postman (its a free google program you can get at the google store) to make sure the error is not on the server side. Use Net:http it comes with ruby so you do not need to install it but you have to require it.
Require it by:
require "net/http"
require "uri"
Use this cheatsheet I think you need basic_auth.rb You will see how to form the request.
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 am using OmniAuth to authenticate a user via Github. OmniAuth provides access tokens. Now I want to send the GET or POST request to Github. I don't want to use any gems, I want to do with Net::HTTP. I did it like this:
<%consumer = OAuth::Consumer.new("mshsD0jpgcYwwOEcTW5ZTA", "V6KTqllY5jS392pj4FNFCb5EiOM8DaFzVwr9cS54XQ", { :site => "https://api.github.com", :request_token_path => '/oauth/request_token', :access_token_path => '/oauth/access_token', :authorize_path => '/oauth/authorize', :scheme => :header })%>
<%access_token = OAuth::AccessToken.new(consumer,auth.token,auth.secret)%>
The same I previously did for Twitter worked fine but now I am getting the following error:
uninitialized constant ActionView::CompiledTemplates::OAuth
Even in the same application the same thing is working for Twitter but not for Github.
I searched through Google but found nothing that helped.
You should be using OAuth2 instead of OAuth. I'd actually recommend using Octokit, it's easy to use and Wynn works for GitHub now so part of his job is keeping it up to date. :)
If you want to use Net::HTTP (although I can't imagine why), you can actually do that without any gems. Just put the token you got from OmniAuth in the request's "Authentication" header.
require 'net/https'
require 'uri'
uri = uri = URI.parse("https://api.github.com/users/username")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = { "Authentication" => "token" }
request = Net::HTTP::Get.new(uri.request_uri, headers)
response = http.request(request)
response.body # => A string containing the JSON response
Seeing as you're already using Omniauth and are familiar with it, I'd recommend using the omniauth-github strategy: https://github.com/intridea/omniauth-github
HI ,
i am new to ROR
i am writing Ruby code for calling API blogs
i have written ruby code for
Creating the blog by
require 'net/http'
require 'uri'
url = URI.parse('http://localhost:3000/api/blogs/create.xml')
req = Net::HTTP::Post.new(url.path)
req.basic_auth 'a', 'a'
req.set_form_data({'blogpost[title]'=>'TestingAPIBlogposttitle',
'blogpost[description]'=>'Testing api desc',
'blogpost[category_id]'=>'3121'}, ';')
res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req)}
case res
when Net::HTTPSuccess, Net::HTTPRedirection
puts res.body
else
res.error!
end
which runs successfully by creating a new blog
And i have a search code
require 'net/http'
require 'uri'
require 'cgi'
## Change this part according to the api to be accessed and the params to be passed.
uri = URI.parse( "http://localhost:3000/api/blogs/show/blogtitle.xml" )
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.path)
request.basic_auth 'a', 'a'
response = http.request(request)
puts response.body
which returns the
<?xml version="1.0" encoding="UTF-8"?>
<blogpost>
<created-at type="datetime">2010-09-02T08:18:22Z</created-at>
<description><p>Blog desc</p></description>
<slug>blogtitle</slug>
<title>blogtitle</title>
<user>
<firstname>admin</firstname>
<lastname>k</lastname>
<login>admin</login>
</user>
</blogpost>
Now i am trying to Update a BLog
for this how to write the code
i tried by simply changing the POST.new by PUT.new
but it didnt works for me
its showing me the error even if i gave admin User credentials
It might be worth trying a POST request but also adding a _method = 'put' parameter to the request. Rails can simulate a PUT request in this way though I would expect it to respond correctly to an HTTP PUT too.
