Question

android调用webservice怎么传递对象

Answer 1

1.webservice方法要传递参数的对象中包含了日期类型，guid类型。如下所示：

[html] view plain copy
POST /MyWebService.asmx HTTP/1.1
Host: 192.168.11.62
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/AddMaintenanceInfo"

<?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>
<AddMaintenanceInfo xmlns="http://tempuri.org/">
<model>
<Id>guid</Id>
<CarId>guid</CarId>
<Cost>string</Cost>
<Dates>dateTime</Dates>
</model>
</AddMaintenanceInfo>
</soap:Body>
</soap:Envelope>

2.新建一个类CarMaintenanceInfo用于传递参数对象，并使其实现KvmSerializable，如下

[java] view plain copy
public class CarMaintenanceInfo implements KvmSerializable {

/**
* 车辆ID
*/
public String CarId;

/**
* 车辆维修费用
*/
public String Cost;

public String Dates;

@Override
public Object getProperty(int arg0) {
switch (arg0) {
case 0:
return CarId;
case 1:
return Cost;
case 2:
return Dates;
default:
break;
}
return null;
}

@Override
public int getPropertyCount() {
return 3;
}

@Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
switch (arg0) {
case 0:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "CarId";
break;
case 1:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Cost";
break;
case 2:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Dates";
break;
default:
break;
}
}

@Override
public void setProperty(int arg0, Object arg1) {
switch (arg0) {
case 0:
CarId = arg1.toString();
break;
case 1:
Cost = arg1.toString();
break;
case 2:
Dates = arg1.toString();
break;
default:
break;
}

}

}

注意：getPropertyCount的值一定要与该类对象的属性数相同，否则在传递到服务器时，服务器收不到部分对象的属性。

3.编写请求方法，如下：

[java] view plain copy
public boolean addMaintenanceInfo(Context context) throws IOException, XmlPullParserException {

String nameSpace = "http://tempuri.org/";
String methodName = "AddMaintenanceInfo";
String soapAction = "http://tempuri.org/AddMaintenanceInfo";

String url = "http://192.168.11.62:6900/MyWebService.asmx?wsdl";// 后面加不加那个?wsdl参数影响都不大

CarMaintenanceInfo info = new CarMaintenanceInfo();
info.setProperty(0, "9fee02c9-8785-4b49-b389-58ed6562c66d");
info.setProperty(1, "12778787");
info.setProperty(2, "2013-07-29T16:45:20");

// 建立webservice连接对象
org.ksoap2.transport.HttpTransportSE transport = new HttpTransportSE(url);
transport.debug = true;// 是否是调试模式

// 设置连接参数
SoapObject soapObject = new SoapObject(nameSpace, methodName);
PropertyInfo objekt = new PropertyInfo();
objekt.setName("model");
objekt.setValue(info);
objekt.setType(info.getClass());
soapObject.addProperty(objekt);

// 设置返回参数
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);// soap协议版本必须用SoapEnvelope.VER11（Soap
// V1.1）
envelope.dotNet = true;// 注意：这个属性是对dotnetwebservice协议的支持,如果dotnet的webservice
// 不指定rpc方式则用true否则要用false
envelope.bodyOut = transport;
envelope.setOutputSoapObject(soapObject);// 设置请求参数
// new MarshalDate().register(envelope);
envelope.addMapping(nameSpace, "CarMaintenanceInfo", info.getClass());// 传对象时必须，参数namespace是webservice中指定的，

// claszz是自定义类的类型
try {
transport.call(soapAction, envelope);
// SoapObject sb = (SoapObject)envelope.bodyIn;//服务器返回的对象存在envelope的bodyIn中
Object obj = envelope.getResponse();// 直接将返回值强制转换为已知对象
Log.d("WebService", "返回结果：" + obj.toString());

}
catch (IOException e) {
e.printStackTrace();
}
catch (XmlPullParserException e) {
e.printStackTrace();
}
catch (Exception ex) {
ex.printStackTrace();
}

return true;

// 解析返回的结果
// return Boolean.parseBoolean(new AnalyzeUtil().analyze(response));
}

注意：传递date类型的时候其实可以使用Date而不是String。但是需要修改几个地方
1.CarMaintenanceInfo类中的getPropertyInfo(),将arg2.type = PropertyInfo.STRING_CLASS修改为MarshalDate.DATE_CLASS;
2. 在请求方法中的 envelope.setOutputSoapObject(soapObject);下加上 new MarshalDate().register(envelope);
虽然可以使用Date，但是传到服务器上的时间与本地时间有时差问题。

当Android 调用webservice，请求参数中有日期，guid,double时，将这些类型在添加对象前转换为字符串即可。

[java] view plain copy
// 构造request
SoapObject request = new SoapObject(PublishInfo.NAMESPACE, "GetCarListByRegion");
request.addProperty("leftTopLat", String.valueOf(leftTopLat));
request.addProperty("leftTopLng", String.valueOf(leftTopLng));
request.addProperty("rightBottomLat", String.valueOf(rightBottomLat));
request.addProperty("rightBottomLng", String.valueOf(rightBottomLng));

当需要传递一个服务器对象参数时.
[html] view plain copy
<?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>
<GetLicenseDetails xmlns="http://tempuri.org/">
<companyId>guid</companyId>
<licenseNos>
<string>string</string>
<string>string</string>
</licenseNos>
<pageOptions>
<page>int</page>
<rows>int</rows>
<total>int</total>
<sort>string</sort>
<order>string</order>
<skip>int</skip>
<Remark>string</Remark>
</pageOptions>
</GetLicenseDetails>
</soap:Body>
</soap:Envelope>

[java] view plain copy
public ListPageResult<LicenseInfo> getLicenseDetails(String[] licenseNos, int page, int rows, int total) {
// 构造request
SoapObject request = new SoapObject(PublishInfo.NAMESPACE, "GetLicenseDetails");
// 许可证列表
SoapObject deviceObject = new SoapObject(PublishInfo.NAMESPACE, "GetLicenseDetails");
if (licenseNos != null && licenseNos.length > 0) {
for (int i = 0; i < licenseNos.length; i++) {
if (!"".equals(licenseNos[i])) {
deviceObject.addProperty("string", licenseNos[i]);
}
}
request.addProperty("licenseNos", deviceObject);
}
else {
request.addProperty("licenseNos", null);
}
// 分页数据
SoapObject optionObject = new SoapObject(PublishInfo.NAMESPACE, "PageOptions");
optionObject.addProperty("page", page);
optionObject.addProperty("rows", rows);
optionObject.addProperty("total", total);
optionObject.addProperty("sort", null);
optionObject.addProperty("order", "desc");
optionObject.addProperty("skip", 0);
optionObject.addProperty("Remark", null);
request.addProperty("pageOptions", optionObject);
// 获取response
Object response = sendRequest(context, request);
if (!mNetErrorHanlder.hasError(response)) { return ObjectAnalyze.getLicenseDetails(response); }
return null;
}
