AMF - it's a protokol exchange data between flash and server. Flash - it's a Adobe photoshop and other programs. So, I have a problem with exchange data between flash and server. Server sending a correctly packet of the bytes but i can not to correctly read it
Please transfer topic to right part of the forum
Here's the AMF3 spec:
As far as I know, it hasn't changed in many years. The last update to this document that I can find is January 2013.
If you take a look at page 5, section 3 - AMF 3 Data Types, you'll see the list of valid markers and their codes. As far as I can tell, 168 (0xA8), is way past the end of the valid range, suggesting that you (or the library you're using) is either not decoding the data correctly, or the data wasn't encoded correctly at the point of transmission.
IMO, this isn't something new in the protocol. It's data corruption. That said, AMF is pretty old, and I'm not sure off the top of my head who the original authors were. It didn't originate with Flash Player. It's just a binary data transmission protocol that we have encoding/decoding support for, and our implementation works correctly (AFAIK).
I can not agree with you.. Exists independense software "Charles" https://www.charlesproxy.com/ If you will use it that can see all "Externaled objects" and all correctly information inside it. As I understanding exists algoritm for unpack data inside "Externaled object".. It's maybe first bit or packed bits group.. It's information need for me.
AMF - main protokol data exchanges between flash and server. You or your developers should know this nuances. If you know his emails or corporate emails - please write it for me. I wish to implements an using "externalized object" in JS-library
If only it were that easy to contact the developers and get them to write things for you... You'll probably have to do detailed experiments and puzzle this out, especially given the very short lifetime left to Flash Player. Your server must in any case be absolutely able to deal with any data it is sent without crashing.
No doubt someone knows, or once knew, the information. What I doubt is that you will find a person who can and will answer your question. I'm pretty sure Adobe will not consider it their job to help you. I consider your demands optimistic at best. Still, it would be nice for me to be proved wrong in this case.
There are AMF implementations in Flex and BlazeDS, both of which Adobe made open-source and donated to the Apache Foundation. You should be able to use them for reference. I still think you're decoding something wrong. There's no constant that I can find that corresponds to the value that you're talking about. I think that if you look at how externalized objects are handled in the decoding implementations, it should yield some useful clues.
There's a Java implementation in BlazeDS that you could use for reference.
Check out blazeds-4.7.3/core/src/main/java/flex/messaging/io/amf/
You might also check out the implementation in Flex:
All behaviours for types of:
161 - Externalized Object Reference
168 - Externalized Object
have been implemented. Thanks for all
I think your findings are very interesting. Can you share your implementation of 161-168 types? I'm searching as well how to solve that and if you did it, it will help me a lot with this problem
Thanks in advance for your help!
