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。。。。
