Question

I am trying to download an image from a server through sockets. My code works fine, but when I download the image, the size is correct but the image does not open. I don\'t

Answer 1

My reputation is not enough to comment, so have to start a new answer.
ug__'s answer is great, but the line

buffer = string.substring(indexOfEOH+4).getBytes();

has some problems, the buffer will be corrupted. For example,

byte[] before = new byte[]{(byte)0xf1, (byte)0xf2, (byte)0xf3, (byte)0xf4};
String str = new String(before, 0, before.length);
byte[] after = str.getBytes();

before and after will not be the same.

So I modified ug__'s code a little bit:

OutputStream dos = new FileOutputStream("test.jpg");
int count, offset;
byte[] buffer = new byte[2048];
boolean eohFound = false;
while ((count = in.read(buffer)) != -1)
{
    offset = 0;
    if(!eohFound){
        String string = new String(buffer, 0, count);
        int indexOfEOH = string.indexOf("\r\n\r\n");
        if(indexOfEOH != -1) {
            count = count-indexOfEOH-4;
            offset = indexOfEOH+4;
            eohFound = true;
        } else {
            count = 0;
        }
    }
  dos.write(buffer, offset, count);
  dos.flush();
}
in.close();
dos.close();
