The Java-XML method transmits images.

1. Read the image to the byte [] stream

2. Transfer byte [] to base64 encoding (that is, a bunch of strings), put the strings in XML, and the images can be transmitted with XML.

3. decodes the base64 encoding in XML into a byte [] stream and then outputs it as an image.

 

Java implements base64 and byte [] mutual conversion:

Import sun. Misc. base64decoder; // convert base64 to byte []
Import sun. Misc. base64encoder; // convert byet [] to base64
Public class test {
Public static void main (string ARGs []) throws ioexception
{
// Define a base64encoder
Base64encoder encode = new base64encoder ();
// Convert byte [] to base64
String base64 = encode. encode ("five-stroke electronic computer". getbytes ());
// Output base64
System. Out. println (base64 );
// Create a base64decoder
Base64decoder decode = new base64decoder ();
// Convert base64 to byte []
Byte [] B = Decode. decodebuffer (base64 );
// Output the converted byte []
System. Out. println (new string (B ));}
}
