Req: Python MtGox auth example

[osmosis]

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.

Code:

from urllib import urlencode
import urllib2
import time
from hashlib import sha512
from hmac import HMAC
import base64
import json
def get_nonce():
    return int(time.time()*100000)

def sign_data(secret, data):
    return base64.b64encode(str(HMAC(secret, data, sha512).digest()))
      
class requester:
    def __init__(self, auth_key, auth_secret):
        self.auth_key = auth_key
        self.auth_secret = base64.b64decode(auth_secret)
        
    def build_query(self, req={}):
        req["nonce"] = get_nonce()
        post_data = urlencode(req)
        headers = {}
        headers["User-Agent"] = "GoxApi"
        headers["Rest-Key"] = self.auth_key
        headers["Rest-Sign"] = sign_data(self.auth_secret, post_data)
        return (post_data, headers)
        
    def perform(self, path, args):
        data, headers = self.build_query(args)
        req = urllib2.Request("https://mtgox.com/api/0/"+path, data, headers)
        res = urllib2.urlopen(req, data)
        return json.load(res)

cool, this helped speed things up, thanks.

Donation address?

thx kokjo

[kokjo]

im amazed it actually works. it was something i wrote up, in like 10 min.

[molecular]

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

Thank you a lot for posting this!

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

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

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

(key and secret replaced)

Dropped error:

Traceback (most recent call last):
  File "./auth.py", line 48, in <module>
    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..

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

Haha I really an a noob! :-)
Thank you, kokjo!

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

[Ente]

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}

[kokjo]

Code:

args = {"oid": "123-456-bla-bla", "type":"1"}

notice the "" around the 1, AFAIK does urlencode not take numbers, only strings.

[Ente]

Yea, works, great! :-)
Actually I had the "1" in "", my mistake was even more silly.

I did:

Code:

{"123-456-bla-bla": "1"}

expected is:

Code:

{"oid": "123-456-bla-bla", "type":"1"}

Thanks mate, again!

Ente

edit:
wiki says

Code:

oid=#&type=# 

.
I just read that wrong. This is the moment where I really sense the value in programming languages. What the speaker says is what the listener will understand. Without two "but I meant.." in between!

I am having difficulty getting this to work.  Here is the code I am using.  Any thoughts?

I am getting not logged in errors.

Code:

def test():
	key = 'x'
	secret = 'x'
	path = "info.php"
	args = {}

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

key =, etc are variables -- They need to be declared outside of a function. imports/froms should be before any other syntax.

Let me know if you need any more help and I can post my working script (up to Authentication, I wouldn't want to do the work for ya.)
