Poltergeist無法連接到服務器。下面是我得到的錯誤：使用路徑助手時，水豚Poltergeist被迫通過https
Failure/Error: visit root_path
Capybara::Poltergeist::StatusFailError:
Request to 'http://127.0.0.1:58638/' failed to reach server, check DNS and/or server status
我已經上了phantomjs調試輸出，這裏是什麼樣子的相關線路對我說：

這一點似乎是一個線索Network - Resource request error: QNetworkReply::NetworkError(ConnectionRefusedError) ("Connection refused") URL: "https://127.0.0.1/"並且它可能是一個ssl錯誤，所以我添加了phantomjs選項--ignore-ssl-errors=true，但它對響應沒有任何影響。
我切換到capybara-webkit看看是否會提供更多的信息，因爲有些人推薦。我得到一個非常類似的錯誤：

Finished "Visit(http://127.0.0.1:64341/)" with response "Success()"

與托馬斯 - 沃波爾@幫助我意識到，如果我具體的非HTTPS URL中水豚考察，它的工作原理。例如visit "http://localhost:3000"它的工作原理。使用visit root_url的作品，但使用visit root_path我被定向到https和上面的錯誤。
config.force_ssl不正確。我在config/environments/test.rb中設置了config.force_ssl = false，並且在測試環境中也使用pry來檢查Application.config。
任何想法爲什麼通過https發送路徑助手將不勝感激。
如果相關，我可以在命令行上使用phantomjs連接'http：//127.0.0.1：3000 /'。 – equivalentideas
