Omniauth Facebook Error - Faraday::Error::ConnectionFailed

问题


(FYI: I\'m following the Twitter Omniauth from railscast #241. I used Twitter successfully, now going onto Facebook)

As soon as I logged into Facebook using Omniauth, I get this error:

Faraday::Error::ConnectionFailed
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

What does this mean?

This is my code

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, \'<key from fb>\', \'<another key from fb>\'
end

There\'s actually nothing much in my code, all I have is in the sessionController that I want to use to_yaml to see what\'s inside the request.env

class SessionsController < ApplicationController
    def create
        raise request.env[\"omniauth.auth\"].to_yaml
    end
end

How do I solve the Faraday error?

You are getting this error because Ruby cannot find a root certificate to trust.

Fix for Windows: https://gist.github.com/867550

Fix for Apple/Linux: http://martinottenwaelter.fr/2010/12/ruby19-and-the-ssl-error/ <--This site is now down.

Here is the Apple/Linux fix according the site above:

The solution is to install the curl-ca-bundle port which contains the same root certificates used by Firefox:

sudo port install curl-ca-bundle

and tell your https object to use it:

https.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt'

Note that if you want your code to run on Ubuntu, you need to set the ca_path attribute instead, with the default certificates location /etc/ssl/certs.

In the end, that’s what will work on both Mac OS X and Ubuntu:

require 'net/https'
https = Net::HTTP.new('encrypted.google.com', 443)
https.use_ssl = true
https.verify_mode = OpenSSL::SSL::VERIFY_PEER
https.ca_path = '/etc/ssl/certs' if File.exists?('/etc/ssl/certs') # Ubuntu
https.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt' if File.exists('/opt/local/share/curl/curl-ca-bundle.crt') # Mac OS X
https.request_get('/')

I've fixed this on Mac OS X Lion 10.7.4 with this solution:

$ rvm remove 1.9.3 (or whatever version of ruby you are using)
$ rvm pkg install openssl
$ rvm install 1.9.3 --with-openssl-dir=$rvm_path/usr

after this you will need to download the missing cacert.pem file:

$ cd $rvm_path/usr/ssl
$ sudo curl -O http://curl.haxx.se/ca/cacert.pem
$ sudo mv cacert.pem cert.pem

Andrei's answer didn't work for me on Mac OSX 10.8.3. I had reinstalled openssl to install ruby 2.0 some time ago and since then always got this error. I fixed it thanks to Andrei's answer and instructions from the Rails project.

I ran:

$ rvm -v
$ rvm get head
# Installation of latest version of rvm...
$ rvm -v
# rvm 1.19.5 (master)
$ rvm osx-ssl-certs status all
# Certificates for /usr/local/etc/openssl/cert.pem: Old.
# Certificates for /Users/mpapis/.sm/pkg/versions/openssl/0.9.8x/ssl/cert.pem: Old.
$ sudo rvm osx-ssl-certs update all
# Updating certificates...

Then I checked if the certificates were correctly updated by running rvm osx-ssl-certs status all again but /usr/local/etc/openssl/cert.pem was still not updated. I don't know if that was necessary but I did the following:

$ cd /usr/local/etc/openssl/
$ curl -O http://curl.haxx.se/ca/cacert.pem
$ mv cacert.pem cert.pem

After that the problem was fixed. Hope that helps someone else who runs into the same issue.

this worked for me (on Mac OS X):

$ brew install curl-ca-bundle
$ export SSL_CERT_FILE=/usr/local/opt/curl-ca-bundle/share/ca-bundle.crt

Alternative Solution:

[I am Win7 user with manual install the Ruby and Ruby on Rails]

I have the same problem but cannot resolve by the answer that given by this question. By the way, finally, I got problem solved by following url

The RVM website suggests running rvm osx-ssl-certs update all

For Windows 7: the above solution link of Neil Hoff (Fix for Windows: https://gist.github.com/867550) did not work for me.

Here is what works:

Using cmd.exe:

curl -o c:\cacert.pem http://curl.haxx.se/ca/cacert.pem
set SSL_CERT_FILE=c:\cacert.pem

using msysgit bash:

curl -o /c/cacert.pem http://curl.haxx.se/ca/cacert.pem
export SSL_CERT_FILE=/c/cacert.pem

If you do not have curl on your windows 7 command line get it here: http://www.confusedbycode.com/curl/#downloads

original solution is from here - credit to: https://github.com/chef/chef-dk/issues/106

Andrei's answer worked for me, however I ran into a huge roadblock when trying to reinstall Ruby 1.9.3. Because I had installed a new version of Xcode since installing 1.9.3 I was unable to reinstall until I opened the Xcode Preferences and installed the Command Line Tools from the Downloads tab.

Check out certified gem. Description:

Ensure net/https uses OpenSSL::SSL::VERIFY_PEER to verify SSL certificates and provides certificate bundle in case OpenSSL cannot find one
