android之调用webservice 实现图片上传

转:http://www.cnblogs.com/top5/archive/2012/02/16/2354517.html

public void testUpload(){          try{              String srcUrl = "/sdcard/"; //路径              String fileName = "aa.jpg";  //文件名              FileInputStream fis = new FileInputStream(srcUrl + fileName);              ByteArrayOutputStream baos = new ByteArrayOutputStream();              byte[] buffer = new byte[1024];              int count = 0;              while((count = fis.read(buffer)) >= 0){                  baos.write(buffer, 0, count);              }              String uploadBuffer = new String(Base64.encode(baos.toByteArray()));  //进行Base64编码              String methodName = "uploadImage";              connectWebService(methodName,fileName, uploadBuffer);   //调用webservice              Log.i("connectWebService", "start");              fis.close();          }catch(Exception e){              e.printStackTrace();          }      }  connectWebService()方法://使用 ksoap2 调用webservice       private boolean connectWebService(String methodName,String fileName, String imageBuffer) {          String namespace = "http://134.192.44.105:8080/SSH2/service/IService";  // 命名空间,即服务器端得接口,注:后缀没加 .wsdl,                                                                                  //服务器端我是用x-fire实现webservice接口的          String url = "http://134.192.44.105:8080/SSH2/service/IService";   //对应的url           //以下就是 调用过程了,不明白的话 请看相关webservice文档             SoapObject soapObject = new SoapObject(namespace, methodName);              soapObject.addProperty("filename", fileName);  //参数1   图片名          soapObject.addProperty("image", imageBuffer);   //参数2  图片字符串          SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(                  SoapEnvelope.VER10);          envelope.dotNet = false;          envelope.setOutputSoapObject(soapObject);          HttpTransportSE httpTranstation = new HttpTransportSE(url);          try {              httpTranstation.call(namespace, envelope);              Object result = envelope.getResponse();              Log.i("connectWebService", result.toString());          } catch (Exception e) {              e.printStackTrace();          }          return false;      }  

 

2。 服务器端的webservice代码 :

 

public String uploadImage(String filename, String image) {      FileOutputStream fos = null;      try{          String toDir = "C:\\Program Files\\Tomcat 6.0\\webapps\\SSH2\\images";   //存储路径          byte[] buffer = new BASE64Decoder().decodeBuffer(image);   //对android传过来的图片字符串进行解码           File destDir = new File(toDir);            if(!destDir.exists()) destDir.mkdir();          fos = new FileOutputStream(new File(destDir,filename));   //保存图片          fos.write(buffer);          fos.flush();          fos.close();          return "上传图片成功!" + "图片路径为:" + toDir;      }catch (Exception e){          e.printStackTrace();      }      return "上传图片失败!";  }  

 

对android 端进行 单元测试调用testUpload()方法,如果你看到绿条的话,说明调用成功!在服务器下,就可以看到你上传的图片了。。。。
当然,这个demo很简陋,没有漂亮UI什么的,但是这是 android端调用webservice进行上传图片的过程。从服务器下载到android端,道理亦然。欢迎大家交流学习。。。。
