我想重写方法Selenium :: WebDriver.for.这是我试过的：
module SeleniumWebDriverExtension
def self.for(browser,*args)
if browser != :phantomjs
super(browser,*args)
else
options = {
"phantomjs.cli.args" => ["--ssl-protocol=tlsv1"]
}
capabilities = Selenium::WebDriver::Remote::Capabilities.phantomjs(options)
super(browser,desired_capabilities: capabilities)
end
end
end
Selenium::WebDriver.prepend(SeleniumWebDriverExtension)
但是当调用Selenium :: Webdriver.for(：phantomjs)时出现错误.
NoMethodError: super: no superclass method `for' for Selenium::WebDriver::Driver:Class
解决方法
module SeleniumWebDriverExtension
def for(browser,*args)
...
end
end
Selenium::WebDriver.singleton_class.prepend(SeleniumWebDriverExtension)
