Question

Poltergeist无法连接到服务器。这是我得到的错误：

 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

我已经打开了phantomjs调试输出，这对我来说就像是相关的行：

2016-12-14T14:24:47 [DEBUG] WebpageCallbacks - getJsConfirmCallback

{"id":"cbe42cdc-58db-49c5-a230-4a1f4634d830","name":"reset","args":[]}

这一点似乎是一个线索Network - Resource request error: QNetworkReply::NetworkError(ConnectionRefusedError) ( "Connection refused" ) URL: "https://127.0.0.1/"并且它可能是一个ssl错误，所以我添加了phantomjs选项--ignore-ssl-errors=true，但它对响应没有任何影响。

我切换到capybara-webkit，看看是否会提供更多信息，就像有些人推荐的那样。我得到一个非常类似的错误：

"Visit(http://127.0.0.1:64341/)" started page load

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

undefined|0|SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent.

在@ thomas-walpole的帮助下，我意识到，如果我特定一个非https url访问capybara，它可以工作。 E.g visit "http://localhost:3000"它有效。使用visit root_url有效，但使用visit root_path我会转到https和上面的错误。

config.force_ssl不是真的。我已在config.force_ssl = false中设置config/environments/test.rb，并在测试的上下文中使用pry检查Application.config。

非常感谢任何关于道路助手为何通过https发送的想法。

您的应用将请求重定向到https，但Capybara不会运行支持https的应用。如果它是rails应用程序，您可能已在应用程序中启用了#include <stdio.h> #define N 10 int count[N + 1]; // count[n] keeps track of the number of times each fib(n) is called int fib(int n) { count[n]++; if(n <= 1) return n; else return fib(n - 1) + fib(n - 2); } int main() { for(int i = 0; i <= N; i++) { count[i] = 0; // initialize count to 0 } fib(N); // print values of count[] for(int i = 0; i <= N; i++) { printf("count[%d] = %d", i, count[i]); } }选项 - 在测试环境中将其设置为config.force_ssl。如果这不能解决问题，那么你必须浏览你的应用程序，看看为什么它会在测试模式下重定向并关闭这种行为。

Capybara Poltergeist在使用路径助手时被迫使用https
