如何存根调用url (例如http://www.example.com/images/123.png )并返回名为123.png的图像?
我使用的是Rails 3.2,Carrierwave。我试过Fakeweb,但有点迷惑。

经过几个小时的研究,事实证明很简单:
FakeWeb.register_uri(:get, string_or_regxp_of_uri,
body: SupportFiles.uploaded_file("square.jpg"),
content_type: 'image/jpg')我的问题更棘手:
我正在测试FB头像,我得到了whitelst扩展
以上代码将不起作用,因为缺少扩展名
(FB头像网址:https://graph.facebook.com/123/picture)
但真实的FB头像将重定向到CDN或扩展名为
因此,您需要添加另一个存根:
# Register a fake remote image
fake_avatar_uri = "https://graph.facebook.com/fake_avatar.jpg"
# Redirect to a fake uri
FakeWeb.register_uri(:get, %r|https://graph\.facebook\.com/|,
status: ["301", "Moved Permanently"],
location: fake_avatar_uri)
# Feed fake image for the fake uri
FakeWeb.register_uri(:get, fake_avatar_uri,
body: SupportFiles.uploaded_file("square.jpg"),
content_type: 'image/jpg')SupportFiles模块(不是我自己写的:P):
require 'rack/test/uploaded_file'
module SupportFiles
extend ActiveSupport::Concern
included do
let(:an_image) do
open_file("square.jpg")
end
end
def open_file(filename)
File.open(support_file_path(filename))
end
# idea stolen from ActionDispatch::TestProcess#fixture_file_upload
def uploaded_file(filename)
Rack::Test::UploadedFile.new(support_file_path(filename))
end
module_function :uploaded_file
protected
def support_file_path(filename)
Rails.root.join("spec/support/files", filename)
end
module_function :support_file_path
