Question

我正在关注Jumpstart Labs MicroBlogger tutorial，我遇到了一个我无法连接到Twitter的问题。我收到以下错误：

C:/RailsInstaller/Ruby1.9.3/lib/ruby/1.9.1/net/http.rb:799:in `connect': SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (Twitter::Error::ClientError)

    from -e:1:in `load'
    from -e:1:in `<main>'

到目前为止，这是我的代码：

require 'jumpstart_auth'

class MicroBlogger
  attr_reader :client

  def initialize
    puts "Initializing"
    @client = JumpstartAuth.twitter
  end

  def tweet(message)
    @client.update(message)
  end

end

blogger = MicroBlogger.new
blogger.tweet("hey")

Answer 1

如错误消息所示，SSL库无法验证从Twitter服务器返回的SSL证书。在这种情况下，很可能是因为没有为您安装证书颁发机构。

详情和解决方案可在此处获取：

我建议使用“无聊”方法，因为它不涉及运行从互联网上复制的代码（如果链接消失，但更好地在链接上阅读信息时的说明）：

下载http://curl.haxx.se/ca/cacert.pem
将其保存到C:\RailsInstaller\cacert.pem
运行set SSL_CERT_FILE=C:\RailsInstaller\cacert.pem以设置当前shell的位置
在同一个shell中运行您的脚本

Answer 2

如果已将ruby直接安装到Windows，则可以将cacert.pem文件复制到Ruby200dir（例如c：\ ruby200）并从命令提示符运行set SSL_CERT_FILE=[path to the cert file]命令。

请记住，这将要求您为计算机的每次启动添加SSL证书
