Excon::Error::Socket: SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A (OpenSSL::SSL::SSLError)

Question

我正在尝试使用 fog-google 将图像上传到我的 google 云存储。我的代码如下所示：

config.paperclip_defaults = {
  storage: :fog,
  fog_host: "https://#{ENV.fetch('GOOGLE_STORAGE_BUCKET')}.storage.googleapis.com",
  fog_credentials: {
      google_storage_access_key_id: ENV.fetch('GOOGLE_STORAGE_ID'),
      google_storage_secret_access_key: ENV.fetch('GOOGLE_STORAGE_SECRET'),
      provider: 'Google' },
  fog_directory: ENV.fetch('GOOGLE_STORAGE_BUCKET') }

但是，我总是收到这个错误： Excon::Error::Socket: SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A (OpenSSL::SSL::SSLError)

好像连接没有建立成功。

这是错误日志：

Answer 1

这是因为您正在尝试访问 url https，但在您的情况下未能验证 ssl。

尝试添加 OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

编辑 - 对于您对 中间人攻击

的关注

您还可以通过以下步骤添加 ssl 证书来验证您的应用程序

下载 https://curl.haxx.se/ca/cacert.pem 到 path_to_file\cacert.pem。确保将其保存为 .pem 文件，而不是文本文件。
设置环境变量：SSL_CERT_FILE = path_to_file\cacert.pem
重新启动所有 ruby / rails 应用程序并立即重试访问它。

Answer 2

当我从 windows 切换到 Linux 时它起作用了。

Answer 3

使用 Windows Linux 子系统。禁用 IPV6 对我有用（对于 hyper-V）。
