Question

以下是对我使用HTTParty时成功执行的远程服务的API调用。

require 'httparty'

class TheAPI
  include HTTParty
  base_uri 'https://someapp.com'
  # headers  "Content-Type" => "application/json"

  def self.create_job
    post( '/jobs.json', :query => {:apikey => "kOrROwbVPNC34VZYhbET", :job => {:method => "PUT", :at => '2012-01-31T18:36:21', :uri => "http://kasko.com"}})
  end
end

puts TheAPI.create_job

但是当我尝试使用法拉第进行相同的调用时，我得到了这个未知的错误：

require 'faraday_stack'

conn = Faraday.new 'https://someapp.com', ssl: {verify: false} do |builder|
  builder.use   FaradayStack::ResponseJSON,     content_type: 'application/json'
  builder.use   Faraday::Response::Logger#,      Logger.new('faraday.log')
  # builder.use FaradayStack::FollowRedirects,  limit: 3
  builder.use Faraday::Response::RaiseError   # raise exceptions on 40x, 50x responses
  builder.use   Faraday::Adapter::NetHttp
end

# conn.headers[:user_agent] = 'MyLib v1.2'

resp = conn.post "jobs.json", {:apikey => "kOrROwbVPNC34VZYhbET", :job => {:method => "PUT", :at => '2012-01-31T18:36:21', :uri => "http://kasko.com"}}
puts resp

引发的错误是：

NoMethodError: undefined method ‘bytesize’ for #<Hash:0x000001011ab8f8>

您似乎正在使用mislav's recent blog post about Faraday代码示例。您会注意到，在他的示例中，您使用的代码仅用于GET请求，而不是POST请求。当他在页面的前面发出POST请求时，他设置了一个特定的Faraday::Request类型。

根据github的讨论，moment要求您发布JSON数据，因此您需要使用此功能：

builder.use Faraday::Request::JSON

为什么与HTTParty一起使用的api调用不适用于法拉第？
