ah, here comes my next stumbling block:
(still Python, still with the code kokjo was so nice to post)

How do I cancel an order?
I only found old-api-examples (the apt where you POST your credentials directly).
Is it even possible with the newer api?

It expects:
#POST data: oid=#&type=#
#oid: Order ID
#type: 1 for sell order or 2 for buy order

For example:
OID=123asd-123-etz-1542-12947
Type=1

123asd-123-etz-1542-12947=1

How do I pass this string into the "args" variable?

Stupid.. everything else (get info, get orders, buy, sell) works as simple as passing the arguments as a JSON to the .php.
Do I have to rewrite it all just for this single "cancel" order? Or is it only possible with the old API altogether, which will be deactivated in some weeks?

..being noobish again:

Ente

edit:
I would expect something as easy as this to work:

Code:

path_cancel = "0/cancelOrder.php"
oid = "123-124-124-124"
typ = "1"
args_cancel = {oid: typ}

args is a dict. args = {"someparameter": "value of the parameter"}, thats why it does not work.

As much as I like python, but one has to admit that languages that use static typing do have certain advantages.

Code:

from hmac import HMAC

def get_nonce():
    return int(time.time()*100000)

class requester:

        headers = {}
        headers["User-Agent"] = "GoxApi"

        req = urllib2.Request("https://mtgox.com/api/0/"+path, data, headers)
        res = urllib2.urlopen(req, data)
        return json.load(res)

Thank you a lot for posting this!

Uh, python newbie question:
How to use that class?
I tried:

Quote

key = "12345"
secret = "1234567890"
path = "info.php"
args = "123"

tuer = requester(key,secret)
tuer.perform(path,args)

(key and secret replaced)

Dropped error:

Quote

Traceback (most recent call last):
File "./auth.py", line 48, in
tuer.perform(path,args)
File "./auth.py", line 33, in perform
data, headers = self.build_query(args)
File "./auth.py", line 24, in build_query
req["nonce"] = get_nonce()
TypeError: 'str' object does not support item assignment

By the way, what goes in the "args" when none are needed, like when fetching "info"?

Ah, success comes in tiny, bloody steps..

I'm also amazed.

looked at goxsh python impl a while back and I couldn't even figure out wtf was going on...

your solution: drop 2 functions into my sources, change 2-3 lines => switched from user/pass to api key auth.

thanks kokjo, sent a nickle

The wiki has a mtgox authentication example in PHP. Anyone out there have an example they can provide for python? I have been trying to get goxsh.py to work with no luck.
