Ruby on rails SOAPAction是空的

我在Mac和Linux上运行相同的web应用程序

在Mac上，我使用的是Savon 0.7.6，web应用程序运行得非常好；应用程序启动SOAP请求，如下所示：

client = Savon::Client.new("http://pvwatts.nrel.gov/PVWATTS.asmx?WSDL")

req = prep_request(@locationId, @dc_rating, @tilt, @azimuth, @derate, @array_type, @cost)

response = client.get_pvwatts{|soap| soap.input = "GetPVWATTS"; soap.body = req }
rdata = response.to_hash

这将导致以下请求：

Retrieving WSDL from: http://pvwatts.nrel.gov/PVWATTS.asmx?WSDL
SOAP request: http://pvwatts.nrel.gov/PVWATTS.asmx
SOAPAction: http://pvwatts.nrel.gov/GetPVWATTS, Content-Type: text/xml;charset=UTF-8

这将导致以下错误：

谁能告诉我这里出了什么问题？

我找到了解决办法；我的工作代码如下：

response = client.request :wsdl, "get_pvwatts" do
  soap.body = req
end

rdata = response.to_hash

response = client.request :wsdl, "get_pvwatts" do
  soap.body = req
end

rdata = response.to_hash
