如何使用Savon進行包含命名空間的SOAP調用

Question

我正嘗試連接到this SOAP API。具體而言，我試圖通過this login call登錄。

文檔狀態我應進行如下請求：

POST /service/replicatorV4.asmx HTTP/1.1 
Host: demo12231.srv106.webshopdemo.net 
Content-Type: text/xml; charset=utf-8 
Content-Length: length 
SOAPAction: "http://tempuri.org/Login" 

<?xml version="1.0" encoding="utf-8"?> 
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> 
    <soap:Body> 
    <Login xmlns="http://tempuri.org/"> 
     <username>string</username> 
     <password>string</password> 
    </Login> 
    </soap:Body> 
</soap:Envelope> 

當我在例如了SoapUI提出了以下要求：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/"> 
    <soapenv:Header/> 
    <soapenv:Body> 
    <tem:Login> 
     <tem:username>Administrator</tem:username> 
     <tem:password>passw0rd12</tem:password> 
    </tem:Login> 
    </soapenv:Body> 
</soapenv:Envelope> 

然後我得到這個滿意的迴應：

然而，當我與薩翁作出這樣的請求：

require 'savon' 

client   = Savon.client(:wsdl => "http://demo12231.srv106.webshopdemo.net/service/replicatorV4.asmx?WSDL", 
           :open_timeout => 100, 
           :read_timeout => 100, 
           :ssl_verify_mode => :none, 
           :log_level => :debug, 
           :log => false, 
           :logger => Rails.logger, 
           :convert_request_keys_to => :camelcase) 

response  = client.call(:login, :message => {:username => "Administrator", :password => "passw0rd12"}) 

那麼我得到這個不滿意的迴應：

    :multipart=>false, 
    :message=>{:username=>"Administrator", :password=>"passw0rd12"}, 
    :soap_action=>"http://tempuri.org/Login"}>> 

響應的主體部分是：

{:login_response=>{:login_result=>nil, :@xmlns=>"http://tempuri.org/"}} 

，這告訴我，也許該服務確實收到了總體要求，但沒有得到的變量。響應看起來很像的響應，當我在了SoapUI使用錯username和password這個請求：

<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> 
    <LoginResponse xmlns="http://tempuri.org/"> 
     <LoginResult xsi:nil="true"/> 
    </LoginResponse> 
    </soap:Body> 
</soap:Envelope> 

我注意到，命名空間tem變量的預期。這可能與我的問題有關嗎？還是有另一種解釋？

創建一個沒有Rails的純Ruby腳本。

然後根據您使用SoapUI創建的內容檢查輸出。張貼差異，有人將能夠提供幫助。

當我運行此腳本：

require 'savon' 

c = Savon.client(wsdl: 
       "http://demo12231.srv106.webshopdemo.net/service/replicatorV4.asmx?WSDL", 
       log_level: :debug, 
       log: true, 
       pretty_print_xml: true) 
response = c.call(:login, 
        :message => {:username => "Administrator", :password => "passw0rd12"}) 

它爲我工作。這可能是你的Rails部分中的一些干擾。我不做Rails，因此我在這裏沒什麼幫助（我更喜歡Sinatra :-)）。
