使用KSOAP从Android应用程序文件传输到Web服务 [英] Using KSOAP for file transfer from android application to web service

问题描述

我已经从Android应用程序，进一步将使用KSOAP其传送到浏览器的WebService发送的数据。我现在计划将文件从应用程序转移到Web服务。这可能吗？

解决方案

  InputStream为= NULL;
            尝试
            {
            是=新的BufferedInputStream（。新的FileInputStream（Environment.getExternalStorageDirectory（）getAbsolutePath（）+/文件名））;
            }           赶上（FileNotFoundException异常E1）{
            // TODO自动生成catch块
            e1.printStackTrace（）;
            }
                ByteArrayOutputStream BOS =新ByteArrayOutputStream（）;
                尝试{
                而（is.available（）大于0）{
                bos.write（is.read（））;
                }
                }
               赶上（IOException异常E1）{
                // TODO自动生成catch块
                e1.printStackTrace（）;
                }                字节[]的字节数组= bos.toByteArray（）;
           字符串的base64 = Base64.en codeToString（字节数组，Base64.DEFAULT）;
 

第1步：从SD卡的文件，并指定在该文件中的的InputStream

。

第二步：将文件写入 BYTEARRAYOUTPUTSTREAM

第三步：将其转换成流的字节组

第四步：将ByteArray传递到 BASE64STRING

I have sent the data from the android application to the webservice which further will transfer it to the browser by using KSOAP. now i am planning to transfer a file from the app to the web service. Is it possible?

解决方案

            InputStream is = null;
            try
            {
            is = new BufferedInputStream(new FileInputStream(Environment.getExternalStorageDirectory().getAbsolutePath() +"/Filename));
            } 

           catch (FileNotFoundException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
            }


                ByteArrayOutputStream bos = new ByteArrayOutputStream();


                try {
                while (is.available() > 0) {
                bos.write(is.read());
                }
                } 
               catch (IOException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
                }

                byte[] byteArray = bos.toByteArray();               


           String base64= Base64.encodeToString(byteArray, Base64.DEFAULT);

1st step: Get the file from the SDcard and assign that file in INPUTSTREAM.

2nd step: Write the file into BYTEARRAYOUTPUTSTREAM

3rd step: Convert that Stream into BYTEARRAY

4th step: Convert Bytearray into BASE64STRING
