目前，我收到来自欧盟中央银行 gem on rails 的错误消息；

我认为 gem 或 xml 文件夹有问题。但它突然发生了。该应用程序现在在 Rails 上关闭。无法将链接从 http 更改为 https

显然，您面临与此相同的问题：

Ruby open-uri 重定向被禁止

这是因为欧盟中央银行强制重定向到https但openuri图书馆不允许这样做，这就是您收到此错误的原因：redirection forbidden.

有一个名为的 gemopen_uri_redirections将修补openuri以允许重定向。

https://github.com/open-uri-redirections/open_uri_redirections

您需要做的就是：

  • 将此宝石包含在您的Gemfile.
  • $ bundle install安装新添加的 gem。
  • require 'open_uri_redirections'

这应该可以暂时解决您的问题。

另一个修复（推荐）是猴子补丁eu_central_bankgem 覆盖

ECB_RATES_URL 在eu_central_bank/lib/eu_central_bank.rb:20

ECB_90_DAY_URL 在eu_central_bank/lib/eu_central_bank.rb:21

常量用https而不是http.

如下（将此代码放入config/initializers/patch_eu_central_bank.rb）：

require 'eu_central_bank'
class EuCentralBank
  ECB_RATES_URL = 'https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml'.freeze
  ECB_90_DAY_URL = 'https://www.ecb.europa.eu/stats/eurofxref/eurofxref-hist-90d.xml'.freeze
end

您可能会看到一些警告，例如：

warning: already initialized constant EuCentralBank::ECB_RATES_URL.

你可以忍受它，直到 PR 合并到EuCentralBankgem 中。
