TypeError on unserializedMessage. about python-idmefv2

[Samuelbella]

Here is the code I used to test:

import json
from idmefv2 import Message, SerializedMessage

#List of Dict
LDok = json.loads(Sok)
msg = Message()
#Dict
for Dok in LDok :

    payload = SerializedMessage('application/json', Dok)
    msg = Message.unserialize(payload)

With for example :
LDok[0] = {'Version': '2.0.3', 'ID': 'e5f9bbae-163e-42f9-a2f2-0daaf78fefb1', 'CreateTime': '2021-01-18T23:33:05.21Z', 'Analyzer': {'IP': '172.10.5.31', 'Name': 'Front door camera', 'Model': 'Netatmo 42B', 'Category': ['HAR'], 'Data': ['Images'], 'Method': ['Movement']}}

Hi,

Thank you for your report!

Disclaimer: I do not work on this project anymore.

The SerializedMessage class expects a serialized representation of the message as a sequence of bytes.
The call to Message.unserialize() will then unserialize the message for you (using knowledge about the serialization method in use it received as the first argument to SerializedMessage).
This makes the API more generic by decoupling it from a specific serialization method, so that new serialization methods can easily be plugged in later on (XML-based serialization, YAML-based serialization, binary serialization and so on).

Try out the following code:

import json
from idmefv2 import Message, SerializedMessage

# Notice how LDok[0] is now a byte sequence
LDok = [
  b'''
    {
      "Version": "2.0.3",
      "ID": "e5f9bbae-163e-42f9-a2f2-0daaf78fefb1",
      "CreateTime": "2021-01-18T23:33:05.21Z",
      "Analyzer": {
        "IP": "172.10.5.31",
        "Name": "Front door camera",
        "Model": "Netatmo 42B",
        "Category": ["HAR"],
        "Data": ["Images"],
        "Method": ["Movement"]
      }
    }
  '''
]

for Dok in LDok :
    payload = SerializedMessage('application/json', Dok)
    msg = Message.unserialize(payload)
    print(msg)
