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的请求都是错误的，需要执行，我不确定为什么。这是一个堆栈跟踪。如果您能帮助我解决这个问题，我将不胜感激。

以下是代码片段，它在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

下面是错误：

Answer 1

这是执行到期的/lib/faraday/adapter/net_http.rb:82:in 'perform_request' method

  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文档的Net::HTTP.request方法，我下划线

返回HTTPResponse对象。

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

此外，我将重点介绍request是如何生成的，因为我认为一些参数传递不正确，这就是响应花费这么长时间的原因。所以我们应该把重点放在请求体、头和所有其他信息上。

# 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，如果在生产服务器日志中打印一些额外的日志信息，您可以打开这个文件/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'，以编写一些关于某些变量的puts语句，这些变量应该输出到您的生产日志中。

您还需要确保rails应用程序日志配置为打印它们。
