Thank you so much for your quick answer. 🙌 I don't have a CDP log and I didn't even know that there's a dedicated log. The versions are cuprite (0.15)
ferrum (0.14) |

Hello @route, I hope that you're able to see more in that log than I do. 😆 The test is quite long but this is the log after clicking the link: |

I think this is Chrome bug and here's minimal reproducible example: require 'bundler/inline'
gemfile do
gem 'cuprite', path: "../"
gem 'ferrum', path: '../ferrum'
gem "rspec", "~> 3.10"
gem "sinatra", "~> 3.2"
gem "puma", ">= 5.6.7"
end
require "rack/handler/puma"
require "sinatra/base"
class Application < Sinatra::Base
set :root, File.dirname(__FILE__)
set :static, true
set :raise_errors, true
set :show_exceptions, false
get "/" do
%(Hello world! <a href="/attachment.pdf">Download PDF</a>)
end
get "/attachment.pdf" do
attachment("attachment.pdf")
send_file("#{File.dirname(File.expand_path(__FILE__))}/attachment.pdf")
end
end
class Server
attr_reader :host, :port
def initialize(host: "127.0.0.1", port: 31337)
@host = host
@port = port
@app = Application.new
@server_thread = nil
end
def boot!
@server_thread = Thread.new { run }
end
private
def run
options = { Host: host, Port: port, Threads: "0:4", workers: 0, daemon: false }
config = Rack::Handler::Puma.config(@app, options)
log_writer = config.options[:Silent] ? ::Puma::LogWriter.strings : ::Puma::LogWriter.stdio
config.options[:log_writer] = log_writer
log_writer.log "Starting Puma"
log_writer.log "* Version #{Puma::Const::PUMA_VERSION} , codename: #{Puma::Const::CODE_NAME}"
log_writer.log "* Min threads: #{config.options[:min_threads]}, max threads: #{config.options[:max_threads]}"
Puma::Server.new(config.app, nil, config.options).tap do |s|
s.binder.parse(config.options[:binds], log_writer)
s.min_threads = config.options[:min_threads] if s.respond_to?(:min_threads=)
s.max_threads = config.options[:max_threads] if s.respond_to?(:max_threads=)
end.run.join
end
end
server = Server.new
server.boot!
sleep 2
browser = Ferrum::Browser.new
page = browser.create_page
page.go "http://127.0.0.1:31337/"
page.downloads.set_behavior(save_path: "/tmp", behavior: :allow)
page.at_xpath("//a[@href]").click
puts page.downloads.filesTry adding target to the link. |

Hi @route,
long time no see.
I am migrating an old project to Cuprite/Ferrum and this project tackles PDF often.
Somehow I seem to miss an important bit so maybe you have an idea.
I added a helper that should force PDF to be downloaded (I got this code from your comment):
And I can see the
putsstatement for pretty much all the requests before but not for the request of the PDF.Could it be because the PDF is opened in a new window (
<a href="..." target="_blank" ...)? Or any other reason?If I am disabling the headless mode, I can see that the PDF URL is opened in a new tab and shows this error message:
It probably makes no difference but the PDF is opened via
first(:xpath, ...).clickwhich then opens the new tab.Also I saw that in Selenium there's an plugin option called
plugins.always_open_pdf_externally.Can this be used here with Ferrum/Cuprite too?
