ruby - 如何在 Ruby 中为 Selenium 配置 read_timeout 和 open_timeout？

Question

通过 Watir 调用 goto() 时出现异常:

Net::ReadTimeout with #<TCPSocket:(closed)>
    /usr/lib/ruby/2.6.0/net/protocol.rb:217:in `rbuf_fill'
    /usr/lib/ruby/2.6.0/net/protocol.rb:191:in `readuntil'

    /var/lib/gems/2.6.0/gems/watir-6.16.5/lib/watir/navigation.rb:16:in `goto'

好像可以修改超时时间，但是我不明白怎么办。

它们被使用 here ，但我该如何配置它们呢？

可以引用Documentation Ruby-Bindings : Internal timeouts

From Documentation : Internal timeouts Internally, WebDriver uses HTTP to communicate with a lot of the drivers (the JsonWireProtocol). By default, Net::HTTP from Ruby's standard library is used, which has a default timeout of 60 seconds. If you call e.g. Driver#get, Driver#click on a page that takes more than 60 seconds to load, you'll see a Timeout::Error raised from Net::HTTP. You can configure this timeout (before launching a browser) by doing:

  client = Selenium::WebDriver::Remote::Http::Default.new
  client.read_timeout = 120 # seconds
  driver = Selenium::WebDriver.for :remote, http_client: client

在 Watir 中可能是这样的

caps = Selenium::WebDriver::Remote::Capabilities.chrome          
client = Selenium::WebDriver::Remote::Http::Default.new
client.read_timeout = 600 
client.open_timeout = 600 
driver =  Watir::Browser.new :chrome, :desired_capabilities => caps, 
:http_client => client
