Android调用Webservice发送文件

一服务器端C#
这里有三个上传方法
1.uploadFile( byte []bs, String fileName);
PC机操作是没有问题
2. uploadImage(String filename,String image);
//android大于1M上传会出问题(内存溢出),把文件件转换为Base64字符串上传
3. uploadResume(String filename,
String image, int tag); //android可以传大文件

二.客户端
要使用 ksoap2库

package cn.serverice;

import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.text.SimpleDateFormat;

import org.ksoap2.SoapEnvelope; import org.ksoap2.serialization.SoapObject; import org.ksoap2.serialization.SoapSerializationEnvelope; import org.ksoap2.transport.HttpTransportSE;

public class Webserverice extends Activity { /** Called when the activity is first created. */ private final String NAMESCROPE="http://mywebservice.cn/"; private final String METHOD_NAME="uploadResume"; private final String URL="http://192.168.1.18/3g/WebService.asmx"; private final String SOAP_ACTION="http://mywebservice.cn/uploadResume"; private Button btn; private TextView txt1; Handler handler=null; //进程中调用view不安全

String str1=""; //返回调用值 @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); txt1=(TextView)findViewById(R.id.txt1); btn=(Button)findViewById(R.id.btnok); btn.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { // TODO Auto-generated method stub final String filename="/sdcard/DCIM/012.3gp"; handler=new Handler(); @SuppressWarnings("unused") Thread webserviceThread = new Thread(){ @Override public void run(){ uploadTest(filename); } }; webserviceThread.start(); } }); } private void uploadTest(String filename) { SimpleDateFormat sDateFormat =new SimpleDateFormat("yyyy-MM-dd_hhmmss"); String file1=sDateFormat.format(new java.util.Date())+filename.substring(filename.indexOf(".")); try { FileInputStream fis=new FileInputStream(filename); //ByteArrayOutputStream baos=new ByteArrayOutputStream(); byte []buffer=new byte[100*1024]; int count=0; int i=0; while((count=fis.read(buffer))>=0){ String uploadBuffer=new String(Base64.encode(buffer,0,count,Base64.DEFAULT)); showServerice(uploadBuffer,file1,i); //续传 for(int j=0;j<1000;j++); i++; } fis.close(); }catch(FileNotFoundException e){ e.printStackTrace(); }catch(IOException e){ e.printStackTrace(); } }

public void showServerice(String image,String file1,int tag) { SoapObject request = new SoapObject(NAMESCROPE, METHOD_NAME); SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11); try { request.addProperty("filename", file1); request.addProperty("image",image); request.addProperty("tag",tag); envelope.bodyOut=request; envelope.dotNet=true; envelope.setOutputSoapObject(request); } catch (Exception e1) { // TODO Auto-generated catch block Log.e("Error","错误1"); } HttpTransportSE ht=new HttpTransportSE(URL); ht.debug=true; try { ht.call(SOAP_ACTION, envelope); SoapObject result = (SoapObject) envelope.bodyIn; str1=result.getProperty(0).toString(); //txt1.setText("uploadImage(filename,image)="+str1+" 成功!"); 在进程中不安全，要加入Runnable handler.post(runnableUi); }catch(Exception e){ Log.d("Error",e.getMessage()); } } Runnable runnableUi=new Runnable(){ //给文本框设值 @Override public void run() { //更新界面 txt1.setText("uploadImage(filename,image)="+str1+" 成功!"); } };

}
