<p>法拉第 0.8.X 和 typhoeus</p>

支持好;)

嗯我设置：

conn = Faraday.new(url, ssl: {verify: false}) 做 |builder|
builder.response :follow_redirects, :limit => 3, :standards_compatible => false, :cookie => :all
builder.adapter :typhoeus
结尾

请求已发送，但带有 net_http ！
如何切换到 em_http 的typhoeus？
在 0.7.X typhoeus 运行良好。

我的堆栈跟踪：
https://gist.github.com/3743068

我设置了 typhoeus 或 em_http 适配器，但在日志中：
/home/johnbat26/.rvm/gems/ruby-1.9。 3-p194@webex/gems/faraday-0.8.4/lib/faraday/adapter/net_http.rb :54:in new' /home/johnbat26/.rvm/gems/ruby-1.9.3-p194@webex/gems/faraday-0.8.4/lib/faraday/adapter/net_http.rb:54:in create_request'
/home/johnbat26/.rvm/gems/ruby-1.9。 3-p194@webex/gems/faraday-0.8.4/lib/faraday/adapter/net_http.rb :74:in perform_request' /home/johnbat26/.rvm/gems/ruby-1.9.3-p194@webex/gems/faraday-0.8.4/lib/faraday/adapter/net_http.rb:37:in call'

服务器得到状态 503 的响应，但 net_http 得到错误：
错误
nil:NilClass 的未定义方法 `strip'

您正在像这样初始化法拉第连接：

conn = Faraday.new(url, ssl: {verify: false}) do |builder|
  builder.response :follow_redirects, :limit => 3, :standards_compliant => false, :cookie => :all
  builder.adapter :typhoeus
end

看起来没问题。 但是您是否使用相同的连接来发出请求？ 您还没有向我们展示您使用 Faraday 执行请求的代码。 也许您正在使用两个不同的法拉第连接。

提示：尝试使用带有默认选项的 follow_redirects：

builder.response :follow_redirects

我在调试模式下看到对象 conn 使用适配器 typhoeus，但在日志中我看到 net_http？！ 为什么？

我使用下一个代码：

require 'faraday'
require 'faraday_middleware'
require 'em-http'
require 'typhoeus'


module MediationHelper
 # Parameters:
  # url = args[:url]
  # method = args[:method] || :post
  # adapter = args[:adapter] || :net_http
  # body = args[:body] || ""
  # params = args[:params]
  # authentication = args[:auth]
  # headers = args[:headers] || {'Content-Type' => 'text/xml; charset=utf-8'}
  # timeout = args[:timeout] || 60
  # open_timeout = args[:open_timeout] || 60
  #
  def self.send_http_request(args)
    url = args[:url]
    method = args[:method] || :post
    adapter = args[:adapter] || :net_http
    params = args[:params]
    body = args[:body] || ""
    authentication = args[:auth]
    headers = args[:headers] || {'Content-Type' => 'text/xml; charset=utf-8'}
    timeout = args[:timeout] || 60
    open_timeout = args[:open_timeout] || 60
    conn = Faraday.new(url, ssl: {verify: false}) do |conn|
      conn.response :follow_redirects
      conn.adapter adapter
    end
    conn.basic_auth(args[:username], args[:password]) if authentication
      response = conn.send(method) do |req|
        req.headers.update headers
        req.body = body
        req.params = params if params
        req.options = {
            :timeout => timeout, # open/read timeout Integer in seconds
            :open_timeout => open_timeout, # read timeout Integer in seconds
        }
      end
    response
  end
end

接下来我调用这个：

      response_for_login_request = MediationHelper.send_http_request(:url => url,
                                                                     :body => login_request_xml,
                                                                     :adapter => :typhoeus
                                                                     :headers => {'Content-Type' => "text/xml; charset=utf-8",
                                                                                  'Cookie' => my__cookie,
                                                                                  'SOAPAction' => '""'})

我设置：
conn.response :follow_redirects
并仍然得到错误：
例外
无方法错误
错误
nil:NilClass 的未定义方法 `strip'

对不起。 是我的错误。
我做了 2 个请求，忘记了使用默认适配器的第二个请求。
对于 typhoeus，不会出现此错误。
但是如何处理 net_http 适配器并且出现错误： undefined method `strip' for nil:NilClass ？

抱歉我忘了回复这个。 您可能正在传递一个为零的标头值，而 net_http 试图将标头值作为字符串进行处理。

要解决此问题，请确保您传递的任何标头实际上都具有字符串值。
