This question already has an answer here:
I've followed Railscast #235 to try and set up a minimal Facebook authentication.
I've first set up a Twitter authentication, as done by Ryan himself. That worked flawlessly.
I then moved on to adding a Facebook login. However, after authorizing the app the redirect to /auth/facebook/callback fails with:
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed
I am working on localhost. I didn't set up any SSL within the app. What am I doing wrong?
The real problem is that Faraday (which Omniauth/Oauth use for their HTTP calls) is not wasn't setting the ca_path variable for OpenSSL. At least on Ubuntu, most root certs are stored in "/etc/ssl/certs". Since Faraday isn't wasn't setting this variable (and currently does not have a method to do so), OpenSSL isn't wasn't finding the root certificate for Facebook's SSL certificate.
I've submitted a pull request to Faraday which will add support for this variable and hopefully they will pull in this change soon. Until then, you can monkeypatch faraday to look like this or use my fork of Faraday. After that, you should specify version 0.3.0 of the OAuth2 gem in your Gemspec which supports the passing of SSL options through to Faraday. All you need to do now is upgrade to Faraday 0.6.1, which supports passing of the ca_path variable and upgrade to OmniAuth 0.2.2, which has the proper dependencies for OAuth2. You'll then be able to properly fix this issue by just adding the following to your Omniauth initializer:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, FACEBOOK_KEY, FACEBOOK_SECRET, {:client_options => {:ssl => {:ca_path => "/etc/ssl/certs"}}}
end
So, to recap:
Faraday needs to be updated to support SSL ca_path.Install Faraday 0.6.1Your app needs to use OAuth2 version 0.3.0. You may need to fork omniauth since it currently has a minor version dependency in the 0.2.x tree.Upgrade to OmniAuth 0.2.2- Modify your provider initializer to point to your system's certificate path ("/etc/ssl/certs" on Ubuntu et al)
Hopefully the next releases of both Faraday and Omniauth will incorporate this solution.
Thanks to KirylP above for setting me on the right path.
I was having this problem and tried using the :ca_path argument without success. After looking through Github for awhile, I came across a suggestion that mentioned using :ca_file and point directly to the certification.
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, 'secret_key', 'secret_key',
:client_options => {:ssl => {:ca_file => '/etc/pki/tls/certs/ca-bundle.crt'}}}
end
If you need to get the path to your systems certification files (and your using linux) simply type from the terminal. This will give you a bunch of information about your SSL setup, including the path (refer to OPENSSLDIR). You'll need to add certs/ca-bundle.crt to the path provided.
open-ssl version -a
I am on ubuntu 10.10 (Maverick)... struggled about 6 hours before I got it to work, sharing my experience
- did not try monkey patch
- tried {:client_options => {:ssl => {:ca_path => "/etc/ssl/certs"}} but still not worked
- tried ruby 1.8.7 still not worked
- tried different versions of omniauth & faraday, still no luck.
The only thing that made it to work was following (thanks Alex)
if Rails.env.development?
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
end
Managed to go through SSL Certificate Verification like it has to be. My project is using 37signals ID for Basecamp integration (Ruby 1.9.2-p130, Rails 3.0.4).
RAILS_ROOT/config/initializers/omniauth.rb:
require 'omniauth/oauth'
Rails.application.config.middleware.use OmniAuth::Strategies::ThirtySevenSignals,
'CLIENT_ID', 'CLIENT_SECRET', {client_options: {ssl: {ca_file: Rails.root.join('gd_bundle.crt').to_s}}}
module OAuth2
class Client
def initialize(client_id, client_secret, opts = {})
adapter = opts.delete(:adapter)
self.id = client_id
self.secret = client_secret
self.site = opts.delete(:site) if opts[:site]
self.options = opts
self.connection = Faraday::Connection.new(site, {ssl: opts.delete(:ssl)})
self.json = opts.delete(:parse_json) # ^ my code starts here
if adapter && adapter != :test
connection.build { |b| b.adapter(adapter) }
end
end
end
end
Where 'CLIENT_ID', 'CLIENT_SECRET' you can get at 37signals.com and certificates bundle file gd_bundle.crt from GoDaddy because 37signals are using their CA.
If you are deploying to Heroku, you want to point to the specific file location. This works for me (in config/initializers/omniauth.rb):
Rails.application.config.middleware.use OmniAuth::Builder do
# This cert location is only for Heroku
provider :facebook, APP_ID, APP_SECRET, {:client_options => {:ssl => {:ca_file => "/usr/lib/ssl/certs/ca-certificates.crt"}}}
end
I solved this with CA bundle from: http://certifie.com/ca-bundle/
And in my Devise initializer:
:client_options => { :ssl => { :ca_file => "#{Rails.root}/config/ca-bundle.crt" } } }
Looks like Omniauth now uses a newer version of Faraday, which explains why the monkey patch above wasn't working for me. I agree there must be a better way, but for anyone else who just needs to get it working to test, here's an updated version:
(create a file in your initializers directory with the following code)
require 'faraday'
module Faraday
class Adapter
class NetHttp < Faraday::Adapter
def call(env)
super
url = env[:url]
req = env[:request]
http = net_http_class(env).new(url.host, url.inferred_port)
if http.use_ssl = (url.scheme == 'https' && env[:ssl])
ssl = env[:ssl]
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.cert = ssl[:client_cert] if ssl[:client_cert]
http.key = ssl[:client_key] if ssl[:client_key]
http.ca_file = ssl[:ca_file] if ssl[:ca_file]
http.cert_store = ssl[:cert_store] if ssl[:cert_store]
end
http.read_timeout = http.open_timeout = req[:timeout] if req[:timeout]
http.open_timeout = req[:open_timeout] if req[:open_timeout]
if :get != env[:method]
http_request = Net::HTTPGenericRequest.new \
env[:method].to_s.upcase, # request method
!!env[:body], # is there data
true, # does net/http love you, true or false?
url.request_uri, # request uri path
env[:request_headers] # request headers
if env[:body].respond_to?(:read)
http_request.body_stream = env[:body]
env[:body] = nil
end
end
begin
http_response = if :get == env[:method]
# prefer `get` to `request` because the former handles gzip (ruby 1.9)
http.get url.request_uri, env[:request_headers]
else
http.request http_request, env[:body]
end
rescue Errno::ECONNREFUSED
raise Error::ConnectionFailed, $!
end
http_response.each_header do |key, value|
response_headers(env)[key] = value
end
env.update :status => http_response.code.to_i, :body => http_response.body
@app.call env
end
end
end
end
all of the solutions didnt work for me, then i've found this
http://railsapps.github.io/openssl-certificate-verify-failed.html
rvm osx-ssl-certs update all
osx 10.8 ruby 2.0.0 via rvm
Edit: Check the answer below as it is more relevant
This worked for me (fix courtesy of https://github.com/jspooner):
Create a file in your initializer's directory with the following monkey patch:
require 'faraday'
module Faraday
class Adapter
class NetHttp < Faraday::Adapter
def call(env)
super
is_ssl = env[:url].scheme == 'https'
http = net_http_class(env).new(env[:url].host, env[:url].port || (is_ssl ? 443 : 80))
if http.use_ssl = is_ssl
ssl = env[:ssl]
if ssl[:verify] == false
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
else
http.verify_mode = OpenSSL::SSL::VERIFY_NONE # <= PATCH or HACK ssl[:verify]
end
http.cert = ssl[:client_cert] if ssl[:client_cert]
http.key = ssl[:client_key] if ssl[:client_key]
http.ca_file = ssl[:ca_file] if ssl[:ca_file]
end
req = env[:request]
http.read_timeout = net.open_timeout = req[:timeout] if req[:timeout]
http.open_timeout = req[:open_timeout] if req[:open_timeout]
full_path = full_path_for(env[:url].path, env[:url].query, env[:url].fragment)
http_req = Net::HTTPGenericRequest.new(
env[:method].to_s.upcase, # request method
(env[:body] ? true : false), # is there data
true, # does net/http love you, true or false?
full_path, # request uri path
env[:request_headers]) # request headers
if env[:body].respond_to?(:read)
http_req.body_stream = env[:body]
env[:body] = nil
end
http_resp = http.request http_req, env[:body]
resp_headers = {}
http_resp.each_header do |key, value|
resp_headers[key] = value
end
env.update \
:status => http_resp.code.to_i,
:response_headers => resp_headers,
:body => http_resp.body
@app.call env
rescue Errno::ECONNREFUSED
raise Error::ConnectionFailed.new(Errno::ECONNREFUSED)
end
def net_http_class(env)
if proxy = env[:request][:proxy]
Net::HTTP::Proxy(proxy[:uri].host, proxy[:uri].port, proxy[:user], proxy[:password])
else
Net::HTTP
end
end
end
end
end
I'm using Faraday 0.6.1, and OAUTH2 (alone, not wrapped by anything). This was enough to solve the problem for me (on Gentoo, should work on Ubunto)
Turn this
client = OAuth2::Client.new(FACEBOOK_API_KEY, FACEBOOK_API_SECRET, :site => FACEBOOK_API_SITE)
Into this
client = OAuth2::Client.new(FACEBOOK_API_KEY, FACEBOOK_API_SECRET, :site => FACEBOOK_API_SITE, :ssl => {:ca_path => '/etc/ssl/certs' })
My problem was solved by ensuring that openSSL was using the right certificate directory:
For my system(ubuntu64) this was: ENV['SSL_CERT_DIR'] = '/usr/share/ca-certificates/'
This was using jruby-openssl with JRuby 1.6.0
I just added this setting to development.rb
I know this sounds trivial, but make sure you are using the right protocol. I kept getting this error and then realized that I was trying to connect via http. 1.5 hours wasted because I am an idiot.
This seems to be a 1.9.x issue. Reverting to 1.8.7 fixed the issue.
Here's what I did that helped if you are specifically having a problem on Leopard.
My cert was old and needed to be updated. I downloaded this:
http://curl.haxx.se/ca/cacert.pem
Then replaced my cert which was found here on Leopard:
/usr/share/curl/curl-ca-bundle.crt
Reload whatever you have that's accessing it and you should be good to go!
Just because instructions were a slight bit different for what worked for me, I thought I add my 2 cents:
I'm on OS X Lion and using macports and rvm
I installed curl-ca-bundle:
sudo port install curl-ca-bundle
Then I adjusted my omniauth config to be this:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, APP_CONFIG['CONSUMER_KEY'], APP_CONFIG['CONSUMER_SECRET'],
:scope => 'https://www.google.com/m8/feeds https://www.googleapis.com/auth/userinfo.profile',
:ssl => {:ca_path => "/share/curl/curl-ca-bundle.crt"}
end
On Ubuntu, all I had to do was update /environments/development.rb to:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, FACEBOOK_KEY, FACEBOOK_SECRET, {:client_options => {:ssl => {:ca_path => "/etc/ssl/certs"}}}
end
and then:
cd /etc/ssl/certs
sudo wget http://curl.haxx.se/ca/cacert.pem
wola!
I finally found a fix for Mountain Lion. See: http://coderwall.com/p/f4hyqw
rvm pkg install openssl
rvm reinstall 1.9.3 --with-openssl-dir=$rvm_path/usr
I encountered a similar error using RVM on Mountain Lion. It seems that Ruby can't find the CA certificate it needs to authorise the SSL connection. You need to install one. This solution did the trick:
http://fredwu.me/post/28834446907/fix-openssl-error-on-mountain-lion-and-rvm
(Although I couldn't actually load that page in my browser, I had to find it in the Google cache.)
Here's the short answer:
curl http://curl.haxx.se/ca/cacert.pem -o ~/.rvm/usr/ssl/cert.pem
And you're done.
