簡單的Savon SOAP請求不起作用

Question

我有以下WSDL，從soapUI生成。當我測試soapUI的 請求時，它工作正常，但從savon中拋出異常。 我在Linux上使用savon 0.9.2。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/ 
envelope/" xmlns:mes="http://www.domain.com/sub/05/00/Messages"> 
    <soapenv:Header/> 
    <soapenv:Body> 
     <mes:loginRequest> 
     <!--Optional:--> 
     <mes:Username>admin</mes:Username> 
     <!--Optional:--> 
     <mes:Password>pass</mes:Password> 
     <!--Optional:--> 
     <mes:ImpersonationUsername></mes:ImpersonationUsername> 
     <!--Optional:--> 
     <mes:ApplicationName></mes:ApplicationName> 
     </mes:loginRequest> 
    </soapenv:Body> 
</soapenv:Envelope> 

腳本，這會導致錯誤：

require 'rubygems' 
require 'savon' 
require 'pp' 

client = Savon::Client.new "http://domain/Service.asmx?WSDL" 

response = client.request(:mes, "login") do 
    soap.body = { 
"mes:Username" => "test", 
"mes:Password" => "test", 
"mes:ImpersonationUsername"=>"Test", 
"mes:ApplicationName"=>"test" 
} 
end 
pp response.to_hash 

輸出：

D, [2011-05-10T16:06:14.316827 #11254] DEBUG -- : <?xml version="1.0"

     :exception_type=>"System.NullReferenceException",

    :fault_code=>"UnknownError"}, 
    :xmlns=> 
    "http://www.domain.com/sub/05/00/Messages"}} 

從了SoapUI的輸出如下：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <soap:Body> 
     <LoginResult xmlns="http://domain/sub/05/00/Messages"> 
     <UserTicket>95bfaa81149f4c118c8724b837235cd5</UserTicket> 
     </LoginResult> 
    </soap:Body> 
</soap:Envelope> 

Answer 1

您可能要在你的savon請求中設置命名空間： client.namespaces["xmlns:mes"] = "http://www.domain.com/sub/05/00/Messages"

Answer 2

你發送的請求創建以下SOAP消息

<?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:mes="urn:namespace.com" 
        xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> 
    <env:Body> 
    <mes:login> 
    <mes:Username>test</mes:Username> 
    <mes:Password>test</mes:Password> 
    <mes:ImpersonationUsername>Test</mes:ImpersonationUsername> 
    <mes:ApplicationName>test</mes:ApplicationName> 
    </mes:login> 
    </env:Body> 

我想這是不是你的意圖是什麼？ 請插入以下行到你的代碼中。新

Savon.configure do |c| 
    c.log = true 
end 

，顯示了即將離任的消息後。
