stdcarrot / py3amf Goto Github PK

It would be great if version 0.8.7 was available in PyPi, since the http header fix is really import for me.

It seems, the Python Py3amf does not have last 2 objects supported from this list:

undefined-marker=0x00 
null-marker=0x01 
false-marker=0x02 
true-marker=0x03 
integer-marker=0x04
double-marker=0x05 
string-marker=0x06 
xml-doc-marker=0x07 
date-marker=0x08 
array-marker=0x09 
object-marker=0x0A 
xml-marker=0x0B 
byte-array-marker=0x0C
vector-int-marker=0x0D
vector-uint-marker=0x0E
vector-double-marker=0x0F
vector-object-marker=0x10
dictionary-marker=0x11

If I am wrong, please tell me where. When I try to parse amf3 content that has dictionary, it fails.

Hi, i have problem decoding amf data included with this character �
this is my code :

    def decodeEnvelope(self, resp):
        # Decode the Base64 encoded response to bytes
        decoded_bytes = base64.b64decode(resp)

        # Attempt to decode the bytes as unicode with ignoring errors
        decoded_data = decoded_bytes.decode('latin-1', errors='ignore')
        
        # Decode the AMF (Action Message Format) data directly
        try:
            decodedAMF = remoting.decode(decoded_data)
            return decodedAMF
        except Exception as e:
            print(f"Failed to decode AMF data: {e}")
            return None

and the resp data is AAAAAAABAAsvMS9vblJlc3VsdAAEbnVsbAAAAuIDAAZzdGF0dXMAP/AAAAAAAAAABWVycm9yAAAAAAAAAAAAAAN1aWQCAAYzNjAxMDkACnNlc3Npb25rZXkCACAxMGE5YjY0YzgxMDdiM2M5NWE1YTVhZDMwMDBjYmI5NgAEaGFzaAIAQGY3ZmFmMzlmYzA1OGEyNzFmZTNmNzRlMzE0Njc3MTg4ZGExN2ZhZmNmZjk3OGQ3MjExNTZlMTNkMmYwOWU0MDcAC3N5c3RlbV90aW1lAgAKdHNqS2lRSFdvUgAEbmV3cwIB8U5ld3M8YnI+LSA5MCsgTGV2ZWwgc2tpbGxzIGFyZSBub3cgYXZhaWxhYmxlIGluIHRoZSBhY2FkZW15ITxicj4tIEVtYmxlbSsgaXMgbm93IGF2YWlsYWJsZSE8YnI+LSBOZXcgRXh0cmVtZSBUYWxlbnQgQ2F0YWNseXNtIGlzIG5vdyBhdmFpbGFibGUhPGJyPi0gTmV3IFBldHMgYXJlIGF2YWlsYWJsZSBpbiBlYWNoIHZpbGxhZ2VzIHBldCBzaG9wITxicj4tIEdlYXIgRmlsdGVycyBhcmUgbm93IGF2YWlsYWJsZSBmb3IgRW1ibGVtKyE8YnI+LSBTa2lsbCBQcmVzZXQgdXBkYXRlZCAzIHNsb3RzL2ZyZWUgdXNlciwgNiBzbG90cy9lbWJsZW0sIDkgc2xvdHMvZW1ibGVtKzxicj48YnI+QnVnIEZpeGVzPGJyPi0gRml4ZWQgYW4gaXNzdWUgd2l0aCBDbGFuIFNob3AsIHNvbWUgaXRlbXMgd2VyZW6SdCBidXlhYmxlLjxicj4tIEZpeGVkIGFuIGlzc3VlIHdpdGggRXllIG9mIE1pcnJvciBUaXRhbiB3aGVuIHVzaW5nIFN1cnByaXNlIEF0dGFjayBDbGFzcyBhbmQgU2VuanV0c3UuAAtjbGFuX3NlYXNvbgIAAjM2AAtjcmV3X3NlYXNvbgIAATUAAAk=

Hello, i am use Wireshark for capture packets and me need decode this.

I try your library but get error - pyamf.DecodeError: Malformed stream (amfVersion=11822)

How i can solve this?

C:\xampp_2015\htdocs\Py3AMF>a

There is two DeprecationWarning in Python 3.12.

pyamf/util/__init__.py:217: DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC).
    datetime.datetime.utcfromtimestamp(-31536000.0)

pyamf/adapters/__init__.py:44
  /home/benoit/Repos/openzim/warc2zim/.hatch/warc2zim/lib/python3.12/site-packages/pyamf/adapters/__init__.py:44: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
    import pkg_resources

First one is probably minor to fix.

Second one is kind of a blocker for Python 3.12, but there is a fallback in the code, so it probably still works in most situations.

The second one can probably easily be fixed with https://docs.python.org/3/library/importlib.resources.html with something like this:

try:
    from importlib import resources
    ....
except:
  try:
    import pkg_resources
    packageDir = pkg_resources.resource_filename('pyamf', 'adapters')
  except:
    packageDir = os.path.dirname(__file__)

I see a new release (0.8.11) of Py3AMF is available on PyPI. However the older 0.8.10 is no longer available for download there. The problem is that external projects depend on it, namely oe-alliance-core, the basis of a ton of satellite receiver set top boxes. That build is now broken. Is there any way you could put 0.8.10 on PyPI again, until things in openoe-alliance catch up?

Incidentally, there's no 0.8.11 on your github either.

msg = messaging.RemotingMessage(
messageId=str(uuid.uuid1()).upper(),
clometOd=None,
operation='findBizObjEx',
destination='superSystemFacadeService',
timeTolive=0,
timestamp=0
)
string = "78daa5524d6fd33018fe2b93cf69643b8d49bc5"
userDtoBytes = bytearray(string, encoding='utf-8')
msg.headers['userDtoBytes'] = userDtoBytes"
userDtoBytes = bytearray(string, encoding='utf-8')
msg.headers['userDtoBytes'] = userDtoBytes

I tried to construct this request but an exception was thrown！
Seems to be an argument that does not support passing a bytearray
I hope to get your reply

Hi. I am trying to use Py3AMF to communicate with an AMF gateway, and I'm getting a bunch of errors in the process, due to poor understanding of the gateway on the remote end (completely because of me). However, I am unable to use pyamf.remoting.decode() to parse the resulting error messages from the server, despite them being valid AMF. I get the following error:

AttributeError: Static attributes {'destination', 'headers', 'rootCause', 'timeToLive', 'timestamp', 'extendedData', 'clientId', 'body', 'messageId'} expected when decoding <class 'pyamf.flex.messaging.ErrorMessage'>

Below is the full hex dump of one such responses that the library refuses to parse, with some data redacted with '#':

Am I doing it wrong, or is there something wrong with the module? How can I handle error messages gracefully? Right now I am catching AttributeError, but I'm missing out on the error message data.
