Faraday: 法拉第::错误::连接失败

创建于 2019-02-27 · 4评论 · 资料来源: lostisland/faraday

我报告这个是因为最后的错误是指法拉第。我已经向 Kickscraper 报告了这个问题，但他们认为问题不在 Kickscraper 脚本中 - https://github.com/markolson/kickscraper/issues/47。

如果法拉第不存在此问题，我深表歉意，但我将不胜感激该社区可以提供的任何帮助或见解。

基础信息

法拉第版本：0.8.11
法拉第中间件版本：0.13.1
红宝石版本：2.6.1

重现步骤

红宝石安装：

rubyinstaller-2.6.1-1-x86.exe installed to 'C:\Program Files\Ruby\Ruby26'

宝石安装：
将 rubygems-3.0.2.zip 解压到C:\Program Files\Ruby\gems\.
使用cd C:\Program Files\Ruby\rubygems\3.0.2 && ..\..\Ruby26\bin\ruby.exe setup.rb安装

踢脚线安装：

嗨@mattmill30 ，你得到的错误很清楚：

Faraday::Error::ConnectionFailed (Failed to open TCP connection to localhost:8888 (No connection could be made because the target machine actively refused it. - connect(2) for "localhost" port 8888))

显然Kickscraper.client期望服务器在端口8888上侦听您的计算机，但情况似乎并非如此。
如果这是唯一的问题，恐怕这不是法拉第的错误，因为问题似乎是没有服务器在localhost:8888上监听。

从堆栈跟踪中可以看出，最后一次调用是

1: from C:/Program Files/Ruby/Ruby26/lib/ruby/2.6.0/net/http.rb:949:in `rescue in block in connect'

所以从法拉第的角度来看，请求被正确地传递给了适配器（在这种情况下是Net::HTTP ），但是在执行它时出现了问题。
您看到引发法拉第错误的原因是因为我们拯救并包装了适配器异常，因此如果您决定将来更改适配器，则无需更改代码。这并不意味着法拉第有问题。

我同意@benrugg的观点，这看起来像是一个代理问题。
我建议你打电话给Kickscraper.proxy看看它会返回什么。
很抱歉将您送回Kickscraper ，但我很放心，由于上述原因，这不是法拉第的问题

谢谢@iMacTia ，我已经运行了'c = Kickscraper.proxy'，它返回“ https://localhost :8888”。

我将如何禁用代理？

mattmill30 于 2019-02-27

@mattmill30我将关闭这个问题（不是法拉第项目的一部分）。

以下是关于项目中代理设置的一些注意事项：

Kickscraper.configure块中有客户端配置行。其中一种配置是proxy 。来源

Kickscraper.configure do |config|
  config.email = '[email protected]'
  config.password = 'This is not my real password. Seriously.'
  config.proxy = nil
end

将其设置为config.proxy = nil或config.proxy = "" 。

否则，请在脚本中查找 LOCAL_PROXY 常量，不要设置它。

设置示例：
https://github.com/markolson/kickscraper/blob/cef996ae73ef3166703d0cb9e452482cb5695c1a/spec/test_constants.rb

希望这可以帮助！
