Rails - Koala / Faraday Gems 执行过期错误

Question

我正在开发一个使用 Koala gem (v2.2) 和 Faraday (0.9.2) 的 Rails 应用程序。似乎很多 Facebook 请求都因需要执行而出错，我不知道为什么。这是一个堆栈跟踪。我将不胜感激有关如何解决此问题的帮助，

这里是代码 sn-p，它要么在 oauth.get_app_access_token 或 app_graph.debug_token 上失败

oauth = Koala::Facebook::OAuth.new(Rails.application.config.facebook_app_id,
                                   Rails.application.config.facebook_app_secret,
                                   nil)

app_access_token = oauth.get_app_access_token # fails here
app_graph = Koala::Facebook::API.new(app_access_token)
token_info = app_graph.debug_token(atoken) # or fails here

这是错误：

这是/lib/faraday/adapter/net_http.rb:82:in 'perform_request' method，执行已过期

  def perform_request(http, env)
    if :get == env[:method] and !env[:body]
      # prefer `get` to `request` because the former handles gzip (ruby 1.9)
      http.get env[:url].request_uri, env[:request_headers]
    else
      # In your case you execture http.request
      http.request create_request(env)
    end
  end

这是 Ruby 文档Net::HTTP.request 方法，我在下划线

返回一个 HTTPResponse 对象。

这是方法中的res，将基于Net::HTTPResponse ruby class

另外我会关注request 是如何制作的，因为我认为某些参数传递不正确，这就是响应需要这么长时间的原因。所以我们应该关注请求体、请求头和所有其他信息。

# File net/http.rb, line 1421
def request(req, body = nil, &block)  # :yield: +response+
  unless started?
    start {
      req['connection'] ||= 'close'
      return request(req, body, &block)
    }
  end
  if proxy_user()
    req.proxy_basic_auth proxy_user(), proxy_pass() unless use_ssl?
  end
  req.set_body_internal body
  res = transport_request(req, &block)
  if sspi_auth?(res)
    sspi_auth(req)
    res = transport_request(req, &block)
  end
  res
end

那么在生产服务器日志中打印一些额外的日志信息怎么样，你可以打开这些文件/usr/lib/ruby/1.9.2/net/http.rb:1168:in 'request' 和/usr/lib/ruby/gems/1.9.2/gems/faraday-0.9.2/lib/faraday/adapter/net_http.rb:82:in 'perform_request'，在一些应该在生产日志中输出的变量上写一些puts 语句。

您还需要确保将 rails 应用程序日志配置为打印它们。
