在PM::WebScreen上显示来自BubbleWrap响应的内容

Question

class WorkoutScreen < PM::WebScreen
  title "Workouts"

  def content
    @response
  end

  def on_load
    set_nav_bar_button :left, title: "Menu", action: :nav_left_button
  end

  def load_started
    @response = ''
    BubbleWrap::HTTP.get("my_url", {async: false, :headers => { "User-Agent" => "value"}}) do |response|
      @response = response.body.to_str
    end
  end

  def nav_left_button
    app_delegate.menu.show(:left)
  end
end

我需要发送带有特定头的HTTP请求，但内容总是为零。我已经检查了嗅探的反应-一切都很好。

如果我这样做

class WorkoutScreen < PM::WebScreen
  title "Workouts"

  def content
    @response = ''
    BubbleWrap::HTTP.get("my_url", {async: false, :headers => { "User-Agent" => "value"}}) do |response|
      @response = response.body.to_str
    end
    @response
  end

我明白了

eb_screen_module.rb:50:in‘`set_content：：是一个目录- read()失败(Errno::EISDIR)

异常
