  • 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。。。。
