encode_www_form_component 法拉第的问题

Question

目前我正在重写整个应用程序，从 Rails 3 到 Rails 6。

在那个过程中我也清理了很多东西。

但这就是我的问题。

我有一个名为 Reusable 的模块，顾名思义，它包含大量可跨模型重用的方法。

我们使用Faraday建立连接到某个服务器：

旧代码如下所示：

module Reusable
  def self.establish_connection(url)
    url = I18n.transliterate(url)
    url = URI.encode(url)
    conn = Faraday.new(url: url) do |builder|
      builder.use :cookie_jar
      builder.use FaradayMiddleware::FollowRedirects
      builder.adapter Faraday.default_adapter
    end
    conn.get
    conn
  rescue Faraday::ConnectionFailed, Faraday::TimeoutError, Errno::ETIMEDOUT => e
    message = "(Timeout::Error) Connection to address: #{url} failed. If address is reachable please run the method again."
  end
end

但是，通过迁移到 Ruby 2.7.0，我们得到了可怕的 URI.encode is obsolete 警告。

为了摆脱它，我重写了整个部分，如下所示：

module Reusable
  def self.establish_connection(url)
    url = I18n.transliterate(url)
    url = URI.encode_www_form_component(url)

    conn = Faraday.new(url: url) do |builder|
      builder.request :url_encoded
      builder.use :cookie_jar
      builder.use FaradayMiddleware::FollowRedirects
      builder.adapter Faraday.default_adapter
    end
    conn.get
    conn
  rescue Faraday::ConnectionFailed, Faraday::TimeoutError, Errno::ETIMEDOUT => e
    message = "(Timeout::Error) Connection to address: #{url} failed. If address is reachable please run the method again."
  end
end

但是，我明白了：

我在 SO 中搜索了这个问题的解决方案，我找到了这个 -> URI::InvalidURIError (bad URI(is not URI?): ):

但这又是 returns 我要使用 URI.encode 我想避免的。

对此有任何解决方案，还是我现在应该静静地忽略过时的警告，直到出现更好的东西？

试试这个：

module Reusable
  def self.establish_connection(url)
    url = I18n.transliterate(url)
    params = Rack::Utils.parse_nested_query(URI(url).query)

    conn = Faraday.new(url: url, params: params) do |builder|
      builder.request :url_encoded
      builder.use :cookie_jar
      builder.use FaradayMiddleware::FollowRedirects
      builder.adapter Faraday.default_adapter
    end
    conn.get
    conn
  rescue Faraday::ConnectionFailed, Faraday::TimeoutError, Errno::ETIMEDOUT => e
    message = "(Timeout::Error) Connection to address: #{url} failed. If address is reachable please run the method again."
  end
end
