Rails：使用Savon對SOAP的請求：無法處理請求

Question

出於學習目的，我嘗試使用Savon來從GlobalWeather SOAP Web服務獲取信息。 http://www.webservicex.net/globalweather.asmx?WSDL

我能夠連接到API並檢索操作：

[:get_weather, :get_cities_by_country]

但是然后當我嘗試通過消息傳遞呼叫時，出現有關未傳遞參數的錯誤：

Savon::SOAPFault in CitiesController#index
(soap:Server) System.Web.Services.Protocols.SoapException: Server was unable 
to process request. ---> System.Data.SqlClient.SqlException: Procedure or 
function 'getWCity' expects parameter '@CountryName', which was not 
supplied. at WebServicex.GlobalWeather.GetCitiesByCountry(String 
CountryName) --- End of inner exception stack trace ---

我的控制器城市代碼如下：

class CitiesController < ApplicationController
  def index
    @operations = client.operations
    @response = client.call(:get_cities_by_country,  message: { CountryName:"Spain" })
  end

  def client
    Savon.client(wsdl: 'http://www.webservicex.net/globalweather.asmx?WSDL')
  end
end

我認為問題可能與根據文檔將哈希消息如何轉換為camelCase有關，因此我嘗試使用全局選項convert_request_keys_to：none，但沒有發生任何不同的情況。

class CitiesController < ApplicationController
  def index
    @operations = client.operations
    client = client do
      convert_request_keys_to :none 
    end
    @response = client.call(:get_cities_by_country,  message: { CountryName: "Spain" })
  end

  def client
    Savon.client(wsdl: 'http://www.webservicex.net/globalweather.asmx?WSDL')
  end
end

Answer 1

我弄清楚了，它確實與convert_request_keys_to選項有關，但是應該在Savon :: client調用中傳遞它

def client
  Savon.client(wsdl: 'http://www.webservicex.net/globalweather.asmx?WSDL', convert_request_keys_to: :none)
end
