Question about disabling plugin/extension

[zsan]

Hello,

Just for my curiosity, is that possible to disable plugin with Ferrum or CDP ?

For example, i have this code with capybara to disable PDF Viewer

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.load_selenium

  browser_options = Selenium::WebDriver::Chrome::Options.new

  browser_options.add_preference(
    :download,
    directory_upgrade: true,
    prompt_for_download: false,
    extensions_to_open: "applications/pdf"    
  )

  browser_options.add_preference(
    :plugins,
    always_open_pdf_externally: true,
    plugins_disabled: ["Chrome PDF Viewer"]    
  )

  Capybara::Selenium::Driver.new(app, browser: :chrome, options: browser_options)
end

[route]

If you have a question, please open discussion, not an issue

Does it have content disposition header?

I am not sure about that, how do i know if it have content disposition header ?

Or maybe you may want to try to real URL

browser = Ferrum::Browser.new(
  headless: false,
  save_path: "/tmp",
  timeout: 60,
  browser_options: {
    "disable-extensions": nil,
  },
)

browser.goto("https://www.africau.edu/images/default/sample.pdf")

Interesting I tried this one with curl and got application/pdf but with Chrome html. Could you try to make a request with headers like in curl and see if this worked?

Same thing, pdf is opened in chrome
Tried with this headers:

browser.headers.set({
  "Content-Type" => "application/pdf",
  "Accept" => "*.*",  
  "Accept-Ranges" => "bytes"
})

That's none of my business, but ok here you go:

require "ferrum"

browser = Ferrum::Browser.new(headless: false,  save_path: "/tmp",  timeout: 5)

browser.network.intercept(request_stage: 'Response')
browser.on(:request) do |request|
  if request.match?(/.*\.pdf\z/)
    request.respond(responseHeaders: request.headers.merge('content-disposition' => 'attachment'))
  else
    request.continue
  end
end

browser.goto("https://www.africau.edu/images/default/sample.pdf")
