使用peddler创建出站履行的错误请求

Question

我正在尝试使用Peddler gem在MWS中创建出站实现。我得到的唯一反馈是Excon::Error::BadRequest (Expected(200) <=> Actual(400 Bad Request)，因此很难找出哪里出了问题。下面是调用API的代码行(解析后的值)：

@client.create_fulfillment_order("186", "186", 2016-08-01T07:35:48Z, "Test shipment number: 186", "Standard", {"Name"=>"Bert the Destroyer", "Line1"=>"Teststreet", "Line2"=>"123", "Line3"=>"", "DistrictOrCounty"=>"", "City"=>"Testcity", "StateOrProvinceCode"=>"CO", "CountryCode"=>"US", "PostalCode"=>"60401", "PhoneNumber"=>"12345678"}, [{"SellerSKU"=>"4785000045", "SellerFulfillmentOrderItemId"=>"4785000045", "Quantity"=>15}], {:fulfillment_policy=>"FillAll", :notification_email_list=>["bertthedestroyer@gmail.com"]})

我好像想不出怎么才能拿回200块钱。有人能帮上忙吗？

实际代码：

address = {
  "Name" => shipment.order.ship_to_name.to_s,
  "Line1" => shipment.order.ship_to_address_1.to_s,
  "Line2" => shipment.order.ship_to_address_2.to_s,
  "Line3" => "",
  "DistrictOrCounty" => "",
  "City" => shipment.order.ship_to_city.to_s,
  "StateOrProvinceCode" => shipment.order.ship_to_state_code.to_s,
  "CountryCode" => shipment.order.ship_to_country_code.to_s,
  "PostalCode" => shipment.order.ship_to_zipcode.to_s,
  "PhoneNumber" => shipment.order.ship_to_phonenumber.to_s
}

items = []
shipment.m2m_line_item_shipments.each do |m2m|
  items << {"SellerSKU" => m2m.vendor_sku.name.to_s, "SellerFulfillmentOrderItemId" => m2m.vendor_sku.name.to_s, "Quantity" => m2m.line_item.actual_quantity }
end

order_comment = "#{shipment.order.store.name} shipment number: " + shipment.id.to_s
opts = {:fulfillment_policy => "FillAll", :notification_email_list => [shipment.order.ship_to_email.to_s] }
created_at = shipment.order.created_at.iso8601

response = @client.create_fulfillment_order(shipment.id.to_s, shipment.id.to_s, created_at, order_comment.to_s, 'Standard', address, items, opts)
order = response.parse
logger.debug "order.inspect: #{order.inspect}"

编辑:经过进一步的挖掘，我发现了这个。我尝试以整数和字符串的形式发送项目数量，但仍然出现相同的错误：

  <Error>
    <Type>Sender</Type>
    <Code>InvalidRequestException</Code>
    <Message>Value AllQuantityZero for parameter  is invalid.</Message>
  </Error>
