如何在sinatra中等待几秒钟重定向

Question

我想在erb answerdoorno上等几秒钟，然后它会重定向到警方。我该如何做到这一点。。。。

post '/answerdoor' do 
    answerdoor = params[:door]  
    door = rand(2).floor
    if answerdoor.include?('yes') && door == 0
        erb :answerdoor, :locals => {:answerdoor => "You Decide to get up and answer the door", :answerdoor2 => " You are in Luck It's Your good buddy Dave." }
    elsif  answerdoor.include?('yes') && door == 1
        erb :answerdoor, :locals => {:answerdoor => "You Decide to get up and answer the door", :answerdoor2 => " Oh No its The cops." }
        redirect to ('/police')
    elsif answerdoor.include?('no') && door == 0
        erb :answerdoorno, :locals => {:answerdoor => "You Decide not to answer the door, but it dosen't Really matter cause Dave walks in anyways."}
    elsif answerdoor.include?('no') && door == 1
        erb :answerdoorno, :locals => {:answerdoor => "You Decide not to answer the door, but it dosen't Really matter cause its the cops and the bust in."}            
        redirct to ('/police')
    end
end

Answer 1

在erb渲染之前，您是否尝试过使用sleep方法？

Answer 2

在Ruby中你不能随心所欲。您应该在HTML中添加一些javascript或HTML，以便在一秒钟或更长时间后重定向。

例如，添加这个元标签

<meta http-equiv="refresh" content="1; url=http://example.com/" />

其中1是秒数
