Solution for image file transfer between client Android and WebService

Recently, the WebService interface was written to provide data to clients and receive data from clients. When the data type is a file of a picture type, the file is converted to a stream and then encoded into a byte stream by Base64, and the string is transferred.

Client code:

public static void Main (string[] args) throws IOException {file File=new file ("D:/272.jpg");     FileInputStream fis = new FileInputStream (file);       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 ()));           Carry out Base64 coding fis.close (); Writesmilfile (Uploadbuffer); System.out.println ("Uploadbuffer:" +uploadbuffer);} Write to txtpublic static void Writesmilfile (String content) {file File1 = new File ("D:/123.txt"); try {file1.createnewfile (); } catch (IOException e) {e.printstacktrace ();}  PrintWriter pw;try {outputstreamwriter os = null; OS = new OutputStreamWriter (new FileOutputStream (File1), "UTF-8");        Os.write (content); Os.close ();} catch (IOException e) {e.printstacktrace ();}}

Server-side code:

Get the picture file from the client (  client processing is the file converted to stream  BASE64 encoded into a string) public string getphotobyandroid (string photopath) {//Picture storage path Put to the formal need to modify string newfilepath= "d:/"; String newfilename =uuid.randomuuid (). toString () + "JPG"; FileOutputStream fos = null;        Byte[] Buffer;try {buffer = new Base64decoder (). Decodebuffer (Photopath);//decode the image string from Android           File DestDir = new File (Newfilepath);            if (!destdir.exists ()) Destdir.mkdir ();          FOS = new FileOutputStream (new File (Destdir,newfilename));   Save Picture          fos.write (buffer);          Fos.flush ();          Fos.close ();         } catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}         System.out.println ("Upload picture Succeeded!" + newfilepath+newfilename);   return newfilename;}
