Question

我环顾四周，无法弄清这个错误。

在运行规范时，在绑定撬为Errno::ECONNREFUSED: Failed to open TCP connection to localhost:3000的情况下，我得到此错误。关于如何解决它的任何想法？

当我运行开发Rails服务器时，错误消失了，代码开始运行。

    10: def call
 => 11:   binding.pry
    12:   image = MiniMagick::Image.open(url)
    13: end

[1] pry(#<ResizeImage>)> image = MiniMagick::Image.open(url)
Errno::ECONNREFUSED: Failed to open TCP connection to localhost:3000 (Connection refused - connect(2) for "localhost" port 3000)
from /Users/josephkonop/.rvm/rubies/ruby-2.5.1/lib/ruby/2.5.0/net/http.rb:939:in `rescue in block in connect'

这是代码

class ResizeImage
  attr_reader :url, :width, :height

  def initialize(params)
    @url = params[:url]
    @width = params[:width]
    @height = params[:height]
  end

  def call
    binding.pry
    image = MiniMagick::Image.open(url)
  end
end

The spec:

RSpec.describe 'Image Resizer', type: :request do
  describe '#create' do
    context 'when valid params' do
      let(:image_url) { ActionController::Base.helpers.asset_path("cat.jpg") }
      let(:width) { 300 }
      let(:height) { 200 }

      before do
        post "/api/v1/resize?url=#{image_url}&width=#{width}&height=#{height}"
      end

      it 'response' do
        expect(response.body).to eq('')
      end
    end
  end
end

Test.rb

config.action_controller.asset_host = 'http://localhost:3000'

Errno :: ECONNREFUSED：无法打开与localhost：4000的TCP连接
