在Ruby中使用Savon时的Soap Request格式

Question

我正在处理soap api，它提供以下示例作为请求XML外观的示例：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsg="http://tempuri.org/wsGenRateEstimate/">
   <soap:Header/>
   <soap:Body>
      <RateEstimateRequestVO>
         <Token>7e2c61c4-8b4c-4d8b-b47f-ed033c6f4307</Token>
         <CustomerNumber>1</CustomerNumber>
         <OriginCity>Dothan</OriginCity>
         <OriginState>AL</OriginState>
         <OriginZip>36303</OriginZip>
         <OriginCountryCode>USA</OriginCountryCode>
         <DestinationCity>Atlanta</DestinationCity>
         <DestinationState>GA</DestinationState>
         <DestinationZip>30303</DestinationZip>
         <DestinCountryCode>USA</DestinCountryCode>
         <WhoAmI>S</WhoAmI>
         <BillDate>050415</BillDate>
         <CODAmount></CODAmount>
         <CODPayType></CODPayType>
         <CODFeePaidBy></CODFeePaidBy>
         <FullCoverage>Y</FullCoverage>
         <FullCoverageAmount>32545</FullCoverageAmount>
         <PrePaidCollect></PrePaidCollect>
         <TotalPalletCount></TotalPalletCount>
         <!--Zero or more repetitions:-->
         <AccLine>
            <AccCode></AccCode>
         </AccLine>
         <!--Zero or more repetitions:-->
         <RateEstimateRequestLine>
            <Weight>122</Weight>
            <Class>70</Class>
            <HandlingUnits></HandlingUnits>
            <HandlingUnitType></HandlingUnitType>
            <Hazmat></Hazmat>
            <CubeU></CubeU>
            <Length></Length>
            <Height></Height>
            <Width></Width>
         </RateEstimateRequestLine>
      </RateEstimateRequestVO>
   </soap:Body>
</soap:Envelope>

下面是我用来在Rails中尝试此请求的代码（出于隐私的考虑而收集我的访问令牌）：

require 'savon'
client = Savon.client({ wsdl: "http://wsportal.aaacooper.com:8188/wsGenRateEstimate.wsdl" })
# this part is to check what the XML I am sending will look like
request = client.build_request(:ws_gen_rate_estimate, message: { Token: "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX", OriginCity: "Birmingham", OriginState: "AL", OriginZip: "35222", OriginCountryCode: "USA", DestinationCity: "New Orleans", DestinationState: "LA", DestinationZip: "70122", DestinCountryCode: "USA", CustomerNumber: "000971733", WhoAmI: "S", PrePaidCollect: "" })
# This will actually send the xml to the server api
response = client.call(:ws_gen_rate_estimate, message: { Token: "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX", OriginCity: "Birmingham", OriginState: "AL", OriginZip: "35222", OriginCountryCode: "USA", DestinationCity: "New Orleans", DestinationState: "LA", DestinationZip: "70122", DestinCountryCode: "USA", CustomerNumber: "000971733", WhoAmI: "S", PrePaidCollect: "" })
render json: {
  "this is a": "test",
  "client_request": request.body,
  "client_response": response.body,
}, status: :ok

对此请求的响应带有“ error_message”，表示我的令牌无效，但是我知道我有一个有效的令牌，并且知道该令牌已完全粘贴在该代码中。 这是XML发送到服务器的样子：

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
     <env:Envelope xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:tns=\"http://tempuri.org/wsGenRateEstimate/\" xmlns:env=\"http://schemas.xmlsoap.org/soap/envelope/\">
        <env:Body>
           <tns:RateEstimateRequestVO>
              <token>XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX</token>
              <originCity>Birmingham</originCity>
              <originState>AL</originState>
              <originZip>35222</originZip>
              <originCountryCode>USA</originCountryCode>
              <destinationCity>New Orleans</destinationCity>
              <destinationState>LA</destinationState>
              <destinationZip>70122</destinationZip>
              <destinCountryCode>USA</destinCountryCode>
              <customerNumber>000971733</customerNumber>
              <whoAmI>S</whoAmI>
              <prePaidCollect></prePaidCollect>
            </tns:RateEstimateRequestVO>
        </env:Body>
     </env:Envelope>

标签名称和名称空间与示例所要求的不同。 这会导致API找不到令牌吗？ 如果是这样，savon gem是否提供更改标签名称或属性的选项？

Answer 1

您的Savon正在生产的节点称为token而服务期望接收Token （大写T ）。 如您所见，所有节点都存在相同的问题：它们以首字母小写发送，并且期望以大写形式接收。

Savon 默认会将键转换为lowerCamelcase。 您可以在全局convert_request_keys_to更改此行为。

全局选项包括:camelcase ， :lower_camelcase ， :upcase和:none 。 在您的问题中，您应该使用:camelcase 。

require 'savon'
client = Savon.client(
  wsdl: "http://wsportal.aaacooper.com:8188/wsGenRateEstimate.wsdl",
  convert_request_keys_to: :camelcase
)

这样，您可以将请求发送为：

request = client.build_request(:ws_gen_rate_estimate, message: { token: "XXXXX", origin_city: "Birmingham" })

并将密钥转换为相应的驼峰式密码。 请注意，您可以将它们snakecase ，并将正确转换。

Answer 2

这可能会有所帮助，因为它在railscasts对我railscasts

Gyoku.convert_symbols_to :camelcase

例如：

def initialize(test)
  Gyoku.convert_symbols_to :camelcase
  client = Savon::Client.new("wsdl_link")
  response = client.request :web, :get_actions, body: { "test" => test }
  if response.success?
  // enter code
  end
end
