Good morning community,
This is the topology I have (I am using ndn-js on both consumer and
producer side):
PRODUCER------NFD-----CONSUMER
I am trying to create a data packet on the producer side every time it
receives an interest packet from the consumer.
The producer is sending an image; therefore it means that I have to split
the contents into chunks of fixed dimension.
This is what I do:
1) var files = document.getElementById('files').files;
var file = files[0];
2) I get the blob object from the file
var blob = file.slice(start,end);
printLine("The dimension is "+blob.size);--> the dimension is the right
one
3) I store the blob object into the data object using the method
data.setContent(blob)
4) When I want to get the dimension from the data content the result of the
print is 0.
var dim = data.getContent().size(
function() {
if (this.buffer != null)
return this.buffer.length;
else return 0;
});
printLine("The dimension is " +dim);---->0
What's wrong in what I have done?
Thank you.
Giuseppe.
