android客户端传递复杂参数给webservice

1.Webservice开发

Webservice由wcf开发完成，我不懂，大概说一下会用到哪些。就在下图中，解释一下下图，是服务器自动生成的，通过URL（http://192.168.13.95:8086/UIServices）在浏览器中打开是这样的，程序中用到的就是URL和namespace，以及方法名，图1的namespace1里面定义的是方法名，namespace2里面定义的是各种数据结构在图4中（特别注意两个命名空间）。图1和图2是一个文件，属于namespace1，图3和图4是一个文件属于namespace2.




图1




图2




图3










图4

图4中的数据结构在c#中是下面这样定义的，生成wsdl文件后就如图4一样




2.android调用

a) 首先要下载添加jar包：ksoap2-android-assembly-2.6.5-jar-with-dependencies.jar，需要在网上下载现在应该到3.0的版本了。

b) 在android中，直接传递给ws参数时支持四种基本类型：int、String、boolean、long，传递基本类型时无须序列化，传递数组是需要继承vector（后面会讲到），而且需要序列化（序列化具体我也不知道，有兴趣的可以研究下）。

c) 调用ws的方法时需要传递相同类型的参数，基本类型就不多说了，还有一种是传递json串，比较简单，这里说一下复杂类型。比如上面的Caption方法，它的参数（图上没有标明）就是CaptionInfo类的对象，那么在android中如何定义一个同类型的呢，首先要定义Caption类，要实现KvmSerializable，是为了序列化，这些参数要和c#中的一样，set和get方法可以不要。

d) 注意那几个继承下来的方法：里面case的顺序要和图4中的各属性顺序一样，case 0：必须是BlackColor，依次类推。getPropertyInfo中的arg2.namespace = 图1中的namespace2，也就是图3中的namespace这个很重要

e) 构造列表，android不支持List，所以要用vector代替，而且必须序列化，数组也是这样定义的

f) 封装成CaptionInfo类，每层都要序列化，此时参数（下面有代码）算是构造好了，然后是调用

g) 下面是调用的主要代码，以及类的写法

<pre name="code" class="java">String nameSpaceString = "http://tempuri.org/";//图1中的namespace1
			String methodName = "Cantion";
			String urlString = "http://192.168.13.95:8086/UIServices";//url
	String soapAction = "http://tempuri.org/IUI/Cantion";//图2中的soapAction
CaptionInfo captionInfo = new CaptionInfo();
SoapObject requests = new SoapObject(nameSpaceString, methodName);
	requests.addProperty("message", captionInfo );//message 是服务器中方法的参数			//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(...);必须加
envelopes.bodyOut = requests;
envelopes.dotNet = true;
envelopes.setOutputSoapObject(requests);
HttpTransportSE hts = new HttpTransportSE(urlString);
	try {
		hts.call(soapAction, envelopes);
		if(envelopes.getResponse() != null)
		{
//解析的时候没找到好的解析方法，只能一步一步按照字段解析
//可以单步调试，看返回值是什么
			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的定义：

<pre name="code" class="java">

class Caption implements KvmSerializable{
	public String BackColor;
	public String CaptionName;

	public String Font;
	public String FontColor;

	}

	}

	public void setContent(String content) {

	}
	public String getFontOpacity() {

	}
	public void setFontOpacity(String fontOpacity) {

	public void setOutlineColor(String outlineColor) {

	@Override

	}
	@Override
