android客戶端傳遞複雜引數給webservice

1.Webservice開發
Webservice由wcf開發完成，我不懂，大概說一下會用到哪些。就在下圖中，解釋一下下圖，是伺服器自動生成的，通過URL（http://192.168.13.95:8086/UIServices）在瀏覽器中開啟是這樣的，程式中用到的就是URL和namespace，以及方法名，圖1的namespace1裡面定義的是方法名，namespace2裡面定義的是各種資料結構在圖4中（特別注意兩個名稱空間）。圖1和圖2是一個檔案，屬於namespace1，圖3和圖4是一個檔案屬於namespace2.
圖1
圖2
圖3
圖4
圖4中的資料結構在c#中是下面這樣定義的，生成
2.android呼叫
a) 首先要下載新增jar包：ksoap2-android-assembly-2.6.5-jar-with-dependencies.jar，需要在網上下載現在應該到3.0的版本了。
b) 在android中，直接傳遞給ws引數時支援四種基本型別：int、String、boolean、long，傳遞基本型別時無須序列化，傳遞陣列是需要繼承vector（後面會講到），而且需要序列化（序列化具體我也不知道，有興趣的可以研究下）。
c) 呼叫ws的方法時需要傳遞相同型別的引數，基本型別就不多說了，還有一種是傳遞
d) 注意那幾個繼承下來的方法：裡面case的順序要和圖4中的各屬性順序一樣，case 0：必須是BlackColor，依次類推。getPropertyInfo中的arg2.namespace = 圖1中的namespace2，也就是圖3中的namespace這個很重要
e) 構造列表，android
f) 封裝成CaptionInfo類，每層都要序列化，此時引數（下面有程式碼）算是構造好了，然後是呼叫
g) 下面是呼叫的主要程式碼，以及類的寫法
<pre name="code" class="java">String nameSpaceString = "http://tempuri.org/";//圖1中的namespace1
String methodName = "Cantion";
String urlString = "http://192.168.13.95:8086/UIServices";//url
String soapAction = "http://tempuri.org/IUI/Cantion";//圖2中的soapAction
CaptionInfo captionInfo = new CaptionInfo();
SoapObject requests = new SoapObject(nameSpaceString, methodName);
requests.addProperty("message", captionInfo );//message 是伺服器中方法的引數 //名，最好保持一致
SoapSerializationEnvelope envelopes =
new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelopes.addMapping(CaptionInfo.NAMESPACE, "Caption", Caption.class);
envelopes.addMapping(CaptionInfo.NAMESPACE,
"ArrayOfCaption", ArrayOfCaption.class);
envelopes.addMapping(CaptionInfo.NAMESPACE, "CaptionInfo", CaptionInfo.class);
//envelopes.addMapping(...);必須加
envelopes.bodyOut = requests;
envelopes.dotNet = true;
envelopes.setOutputSoapObject(requests);
HttpTransportSE hts = new HttpTransportSE(urlString);
try {
hts.call(soapAction, envelopes);
if(envelopes.getResponse() != null)
{
//解析的時候沒找到好的解析方法，只能一步一步按照欄位解析
//可以單步除錯，看返回值是什麼
SoapObject returnObjects = (SoapObject) envelopes.bodyIn;
//SoapObject CaptionList =
(SoapObject)returnObjects.getProperty(0);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}CaptionInfo的定義：
