有人可以帮我解决这个问题。我已经在网上看到了这个问题，但是没有人有足够的答案。
我使用的是Ubuntu，Ruby 1.8.7和OpenSSL 1.0.1
Net::HTTP.ssl_context_accessor 'ssl_version'
uri = URI.parse("https://www.paypal.com")
http = Net::HTTP.new(uri.host, uri.port)
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
http.use_ssl = true
http.ssl_version = :TLSv1
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
返回
OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed
如果我指定TLSv1，为什么会抱怨SSLv3？
我知道它正在使用TLSv1，因为如果我做了
http.ssl_version = :SSLv3
它会返回
OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server hello A: sslv3 alert handshake failure
预期。
我不确定该错误是什么，我的ca-certificates是最新的。
我无法做任何花哨的OpenSSL::SSL::OP_NO_SSLv3内容，因为Ruby 1.8.7不支持任何这些选项。
感谢您的帮助。
相关且有用的答案，但不是解决方案
答案 0 :(得分：3)
正如我在评论中所说，这很可能是影响Ruby 1.8.7和OpenSSL 1.0.1的错误 - 当您尝试连接到使用TLSv1禁用SSLv3的服务器时，它将返回{{ 1}}错误。
经过大量的搜索，这就是我做的事情
certificate verify failed此hack允许您设置http.instance_eval {
@ssl_context = OpenSSL::SSL::SSLContext.new
@ssl_context.set_params({:options=>OpenSSL::SSL::OP_NO_SSLv3})
}
选项，以解决问题。
答案 1 :(得分：1)
Ruby可能无法找到任何值得信赖的根证书，例如参见this question等。你的ruby版本真的旧，我也假设你的证书包也是。你应该更新。几周前，对Ruby 1.9.3的支持已经结束，更不用说支持Ruby 1.8.7了。目前的版本是Ruby 2.2.2。对于旧版本的版本不会有任何修复。
答案 2 :(得分：1)
OpenSSL :: SSL :: SSLError：SSL_connect返回= 1 errno = 0状态= SSLv3读取服务器证书B：证书验证失败...
如果我指定TLSv1，为什么会抱怨SSLv3？
它是OpenSSL中错误消息的工件。不要过分担心（除了＃34;验证失败＆＃34;）。
你没有问过这个问题，但是这里有解决方法。您应该包含ca_file：
Net::HTTP.ssl_context_accessor 'ssl_version'
uri = URI.parse("https://www.paypal.com")
http = Net::HTTP.new(uri.host, uri.port)
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
http.use_ssl = true
http.ssl_version = :TLSv1
http.ca_file = File.join(File.dirname(__FILE__), "ca.pem")
ca.pem应为VeriSign Class 3公共主要证书颁发机构或 VeriSign Class 3公共主要证书颁发机构 - G5 的PEM编码版本。您可以从赛门铁克的网站Use of Root Certificates下获取它。
您可以使用以下命令发现所需的CA证书。您通常对链中的 last 颁发者感兴趣。
发行人是与＆＃34; i：＆＃34; 一起显示的，如 i：/ C = US / O = VeriSign，Inc. / OU = Class 3公共主要证书颁发机构。 ＆＃34; s：＆＃34; 用于主题，以及颁发证书的人。
$ openssl s_client -connect www.paypal.com:443 -tls1 -servername www.paypal.com -showcerts
CONNECTED(00000003)
depth=2 C = US, O = "VeriSign, Inc.", OU = VeriSign Trust Network, OU = "(c) 2006 VeriSign, Inc. - For authorized use only", CN = VeriSign Class 3 Public Primary Certification Authority - G5

我不知道该怎么做这个错误，我的证书是最新的。
不要添加CA Zoo（ca-certs.pem）。您知道认证PayPal的CA，因此请使用它。没有必要再添加300个CA（299个不正确）。
