python-wcfbin's Issues

Recent change breaks support for Python < 2.7.7

This change: bc3b32e

Due to Python Issue 19099, struck.pack can't handle string objects other than native str properly until Python 2.7.7. So if you want to be compatible with all versions of Python 2.7, you'd better use struct.unpack(b'<BBB', fp.read(3)) instead of struct.unpack('<BBB', fp.read(3)).

WARNING:wcf.records.base:type 0x0 not found

I am trying to run wcf2xml on a file, but I get this warning and no output. How do I help you help me proceed?

I have a problem.

from wcf.records import Record, print_records
data = requests.post('http://106.37.208.233:20035/ClientBin/Env-CnemcPublish-RiaServices-EnvCnemcPublishDomainService.svc/binary/GetAllCityDayAQIModels').content
records = Record.parse(data)

but error:
File "D:\untitled\wcf\records\base.py", line 126, in parse
log.debug('Value: %s' % str(obj))
TypeError: str returned non-string (type bytes)

Can I install this package with pip?

I have searched it on pypi.python.org but could not find it.

Support utf8

Error encode binaryxml with utf8 symbols.

Possible false interpretation

i have met one problem "Possible false interpretation" when i call wcf2xml.py file.svc, which leads the xml result doesn't work.

I'm not sure i understand the code, why it doesn't work for Decimal interpretation?

KeyError exceptions when parsing the example WCF dump

I'm trying the code on the packet dump included in the blog post:

https://insinuator.net/2016/08/pentesting-webservices-with-net-tcp-binding/

I've exported the packet from 0x141 to a binary file:

python -c 'import binascii; print binascii.unhexlify("06db010056020b0173040b0161065608440a1e0082ab01400a41637469766974794964040d436f7272656c6174696f6e4964982436393837373766652d653637322d346163322d623163642d623962373464313437396538083d687474703a2f2f736368656d61732e6d6963726f736f66742e636f6d2f323030342f30392f536572766963654d6f64656c2f446961676e6f7374696373b1bef9db6d9c998b4e9a140ebf2d6941a24412adf843211e834c8f4e8f0ce47db9cf3a67440c1e0082ab1401560e42030a054207990e596f7520656e74657265643a2030010101"),'  > test.bin

Running wcf2bin.py test.bin gives the following error:

Traceback (most recent call last):
  File "wcf2xml.py", line 43, in <module>
    records = Record.parse(fp)
  File ".../python-wcfbin/wcf/records/base.py", line 111, in parse
    obj = Record.records[type].parse(fp)
  File ".../python-wcfbin/wcf/records/attributes.py", line 174, in parse
    value = Record.records[type].parse(fp)
KeyError: 0

Even if I add exception handling to the affected parts of the code KeyErrors pop up at other parts of the application, that indicates that this is not a bug, but more like a user error... What am I missing?

problem with Serialization/Arrays Value

I use your project to communicate with Microsoft servers, it works fine except when using Serialization/Arrays :

Answer :

The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://schemas.microsoft.com/online/aws/change/2010/01:syncRequest. The InnerException message was 'Element 'http://schemas.microsoft.com/2003/10/Serialization/Arrays:Value' contains data from a type that maps to the name ':mustUnderstand'. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver if you are using DataContractSerializer or add the type corresponding to 'mustUnderstand' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to the serializer.'.  Please see InnerException for more details.

I tried to look but I admit that I did not find
