get_objects() argument error

[sean-macfarlane]

I'm trying to pass the "added_after" to collection.get_objects but I keep getting this error: TypeError: get_objects() takes 1 positional argument but 2 were given

code: objects = collection.get_objects({"added_after": lastUpdate})

Hi, @sean-macfarlane . Try this:

objects = collection.get_objects(added_after=lastUpdate)

I tried what you suggested and it gives me this error:

the value I am passing for added_after is an iso format datetime string i.e "2018-01-23T05:13:19.080825+00:00"

[gtback]

What server are you testing against? Seems like the server isn't returning a response, which may be because of an error in the client, or maybe not.

Also, ideally it shouldn't matter, but the spec calls for timestamps to be expressed with a Z suffix rather than +00:00:

The timestamp MUST be represented in the UTC timezone and MUST use the “Z” designation to indicate this.

http://docs.oasis-open.org/cti/taxii/v2.0/cs01/taxii-v2.0-cs01.html#_Toc496542710

[sean-macfarlane]

I'm using https://test.freetaxii.com:8000/osint/

And I tried using the string "2018-01-23T05:13:19.080825Z" and using a datetime object cause I saw in the code it would convert it to the correct string format. But both still produce the same error

[gtback]

I can reproduce this. @jordan2175, do you know if this a known issue with the freetaxii-server, or something in the Python client library?

[jordan2175]

@gtback I am not aware of any issue with my code. I do this filter a lot for my unit tests. Do you have an exact URL string you are using that I can test with?

[gtback]

@jordan2175: This url works (assuming the correct Accept header is used):

https://test.freetaxii.com:8000/osint/collections/34f8c42d-213a-480d-9046-0bd8a8f25680/objects/

This URL does not work:

https://test.freetaxii.com:8000/osint/collections/34f8c42d-213a-480d-9046-0bd8a8f25680/objects/?added_after=2018-01-23T05:13:19.080825Z

Note that I also tried encoding the colons in the timestamp as %3A, to match what the Python library will do.

I used the httpie command line utility, so I don't think it's an issue in cti-taxii-client.

http https://test.freetaxii.com:8000/osint/collections/34f8c42d-213a-480d-9046-0bd8a8f25680/objects/?added_after=2018-01-23T05%3A13%3A19.080825Z Accept:"application/vnd.oasis.stix+json; version=2.0"

[sean-macfarlane]

any update on why this isn't working? thanks

[gtback]

@jordan2175, let me know if I'm using an invalid URL to test this; it seems like freetaxii is aborting the connection rather than returning a response (even an empty HTTP response)

FYI

I've used my scala code to ask https://test.freetaxii.com:8000 for the above collection of objects.

I tried: 2018-01-23T05:13:19.080825Z get an error with "Remotely closed" message, get no bundle at all but should return an empty bundle. and 2017-12-03T08:00:38.231Z get a bundle with 7 stix indicator

Note: The 10 indicators returned for collection "34f8c42d-213a-480d-9046-0bd8a8f25680" have dates created in the year 2017. So 2018-01-23T05:13:19.080825Z will not return any objects, but should return a bundle with nothing in it, however we get a "Remotely closed" error instead.

[workingDog]

This is to say this is a known issue with https://test.freetaxii.com:8000. Quote: "The way I have the code right now, if there is no data in the collection that matches your filter, I am returning an error."

Is there another play/test taxii server around?

[jordan2175]

I have a new version based on TAXII 2.1 CSD 01 that I am going to upload to the test server, once we figure out how we are going advertise a CSD version.

It sounds like this isn't an issue in the cti-taxii-client, so I'm going to close this; but if there's anything that needs to be done here, feel free to re-open.
