無法得到薩翁形成正確的XML

Question

我以前使用過SOAP，但很多年前，如果我可以幫助它，請儘量保持清晰。

短篇小說...

• 使用 「SOAP客戶端」 OS X應用程序，我可以得到我想要的反應。
• 如果我使用client.request :foo_web_serivce, :language_count, :body => { :foo_app_id => "...", :session_id => "..." }，那麼我會得到一個Status 200，但我的結果是-1，因爲我相信app_id無法識別。
• 如果我嘗試複製Soap客戶端調用（<LanguageCount>）而不是Savon的調用（<foo_web_service:LanguageCount>），那麼我得到Status 500。

請提前告知並提前致謝。

長篇...

使用SOAP客戶端，我可以看到正確的請求XML是：

User-Agent: Mac OS X; WebServicesCore (357) 
Content-Type: text/xml 
Host: redacted 
Soapaction: http://tempuri.org/redacted/LanguageCount 

<?xml version="1.0" encoding="utf-8"?> 
    <SOAP-ENV:Envelope 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
    SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> 
     <SOAP-ENV:Body> 
     <LanguageCount xmlns="http://tempuri.org/"> 
      <fooAppID xsi:type="xsd:string">12345678-1234-1234-1234-123456789123</fooAppID> 
      <sessionID xsi:type="xsd:string">12345678-1234-1234-1234-123456789123</sessionID> 
     </LanguageCount> 
     </SOAP-ENV:Body> 
    </SOAP-ENV:Envelope> 

然而，當我嘗試做它在控制檯，像這樣：

ruby-1.8.7-p302 > client = Savon::Client.new do |wsdl, http, wsse| 
ruby-1.8.7-p302 >  wsdl.document = "http://FooService.cloudapp.net/FooService.svc?wsdl"

Answer 1

長話短說，我不得不作出3個改變。

1. 改變response = client.request :language_count到 response = client.request "LanguageCount"
2. 新增:xmlns => "http://tempuri.org/"到client.request呼叫
3. 明確稱爲SOAPACTION喜歡的末尾：client.http.headers["SOAPAction"] = '"http://tempuri.org/FooService/LanguageCount"'

希望這可以幫助別人，因爲我一直在SOAP地獄週末，希望我會阻止別人在那裏。
