问通过socket在android和nosejs之间发送文件

EN

File file = new File("/path/image.jpeg");

try {
    FileInputStream fis = new FileInputStream(file);
    byte imgByte[] = new byte[(int) file.length()];
    fis.read(imgByte);

    //convert byte array to base64 string
    String img64 = Base64.encodeBase64URLSafeString(imgByte);

    //send img64 to socket.io servr
} catch (Exception e) {
   //
}

socket.on("image", function (image) {
    console.log(" image réçu : " +image)
    //use fs.writeFile

    image = image.replace(/^data:image\/png;base64,/, "");

    require("fs").writeFile("out.png", image, 'base64',function(err) {
        console.log(err);
    });

});

fs.readFile("/img/your_img_in_server.jpeg", function(err, data){

    var img64 = new Buffer(data, 'binary').toString('base64')
    socket.emit("send_img", img64)

})

socket = IO.socket("http://localhost");
socket.on("send_img", new Emitter.Listener() {

  @Override
  public void call(Object... args) {    
    String data = (String) args[0];
    byte[] b = Base64.decode(data,Base64.DEFAULT);
    //your bitmap data
    Bitmap bmp = BitmapFactory.decodeByteArray(b,0,b.length);

});

socket.connect();
