ruby on rails - 黄瓜/水豚-如何获取当前执行的主机和端口

original title: "ruby on rails - Cucumber / Capybara -- how to get the host and port of the current execution"


I need to download a csv file from my app using Open::URI and to do that I need to give it a fully qualified URI. So whats the best way to get the HOST and more importantly PORT in my cucumber script?

Note I am using Capybara and Selenium

我需要使用Open :: URI从我的应用程序中下载一个csv文件,并为此做一个完全限定的URI。那么,什么是获得HOST以及更重要的是PO的最佳方法?

    You can set port that will be used to spawn an application server

    Capybara.server_port = 31337

    For capybara < 2.0:

    Capybara 2.0:

    FYI, my use case is having clickable links in the mail generated by the integration tests.

    You can use current_host but I don't know if it contains the port. Alternatively you can use current_url and strip the path (and possibly the query string).
