Android上的kSOAP2和SOAPAction

Question

我正嘗試在Android手機上使用kSOAP2訪問Webservice。我認爲連接正在建立，但服務器不會回答我的請求，因爲我沒有提供似乎在SOAP Version 1.1中需要的SOAP Action Header（如果我在這裏錯誤，請糾正我），我有使用，因爲服務器不支持版本1.2。 這是在請求中返回的具體Fault代碼看起來是這樣的：

faultactor null  
faultcode "S:Server" (id=830064966432)  
faultstring "String index out of range: -11" (id=830064966736) 

這是服務器（我運行它在本地主機）上生成的錯誤代碼如下所示：

在WSDL的相關部分（至少這是我在想什麼）看起來是這樣的：

<operation name="createContext"> 
<soap:operation soapAction=""/> 
− 
<input> 
<soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> 
</input> 
− 
<output> 
<soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> 
</output> 
</operation>  

在我的代碼，我加入了頭，但它好像我做錯了：

private static final String SOAP_ACTION = ""; 
//... 
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope (SoapEnvelope.VER11); 
soapEnvelope.setOutputSoapObject(Request); 
AndroidHttpTransport aht = new AndroidHttpTransport (URL); 
//... 
aht.call(SOAP_ACTION, soapEnvelope); 
     SoapPrimitive resultString = (SoapPrimitive) soapEnvelope.getResponse(); 

，因爲我跑出來的想法.. 感謝鄉親任何意見將是巨大的！

Answer 1

SOAP Action由名稱空間和您想要調用的實際方法組成。

另外，SOAP Action需要封裝在「」中才能工作。我有一個類似的錯誤，直到我用輔助方法來生成我的SOAP Action：

public String getSoapAction(String method) { 
    return "\"" + NAMESPACE + method + "\""; 
} 

我希望它有幫助！
