【问题描述】:
最近,我尝试使用 rubygem grpc 版本 1.3.2 作为 clinet 并连接到由 golang 构建的 grpc 服务器。我浏览了GRPC.IO 的文档并在我的代码中使用它。
irb(main):017:0> GRPC::Core::Credentials.new(File.read(CA_FILE_PATH))
NameError: uninitialized constant GRPC::Core::Credentials
from (irb):17
from /usr/local/share/gems/gems/railties-4.2.1/lib/rails/commands/console.rb:110:in `start'
from /usr/local/share/gems/gems/railties-4.2.1/lib/rails/commands/console.rb:9:in `start'
from /usr/local/share/gems/gems/railties-4.2.1/lib/rails/commands/commands_tasks.rb:68:in `console'
from /usr/local/share/gems/gems/railties-4.2.1/lib/rails/commands/commands_tasks.rb:39:in `run_command!'
from /usr/local/share/gems/gems/railties-4.2.1/lib/rails/commands.rb:17:in `<top (required)>'
from bin/rails:4:in `require'
from bin/rails:4:in `<main>'
但是他们的文档具体说,
creds = GRPC::Core::Credentials.new(load_certs) # load_certs typically loads a CA roots file
stub = Helloworld::Greeter::Stub.new('myservice.example.com', creds)
然后我遇到 ChannelCredentials 并且 creds 应该是 ChannelCredentials 对象或符号(例如 :this_channel_is_insecure)。因此,我也尝试了一下。
我从 grpc gem 的源代码中获取了以下函数。此函数在 rspec 测试用例中被调用以加载证书:
def load_certs
data_dir = "#{Rails.root}/certs"
files = ['ca.pem', 'server.key', 'server.pem']
files.map { |f| File.open(File.join(data_dir, f)).read }
end
然后我试了一下,
channel_creds = GRPC::Core::ChannelCredentials.new(load_certs)
stub = Helloworld::Greeter::Stub.new('myservice.example.com', channel_creds)
但以上失败了
E0619 09:59:10.410575570 14208 ssl_transport_security.c:601] Could not load any root certificate.
E0619 09:59:10.410604954 14208 ssl_transport_security.c:1315] Cannot load server root certificates.
E0619 09:59:10.410622519 14208 security_connector.c:837] Handshaker factory creation failed with TSI_INVALID_ARGUMENT.
我也试过了:
channel_creds = GRPC::Core::ChannelCredentials.new(File.read(CA_FILE_PATH))
stub = Helloworld::Greeter::Stub.new('myservice.example.com', creds)
但我得到的只是来自日志或 rpc 服务器的错误:
2017/06/16 10:52:34 transport: http2Server.HandleStreams failed to receive the preface from client: EOF
2017/06/16 10:53:35 transport: http2Server.HandleStreams failed to receive the preface from client: EOF
2017/06/16 10:53:59 transport: http2Server.HandleStreams failed to receive the preface from client: EOF
2017/06/16 10:55:06 transport: http2Server.HandleStreams failed to receive the preface from client: EOF
有没有人成功尝试过启用 SSL/TLS 的 Ruby 客户端 Golang 服务器组合?
