Title: Req: Python MtGox auth example
Post by: osmosis on October 25, 2011, 06:37:56 AM
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.

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

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

Quote

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

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

Dropped error:

    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.

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


Title: Re: Req: Python MtGox auth example
Post by: Ente on January 31, 2012, 01:46:42 PM
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}


Title: Re: Req: Python MtGox auth example
Post by: kokjo on January 31, 2012, 02:03:03 PM
Code:
args = {"oid": "123-456-bla-bla", "type":"1"}

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


Title: Re: Req: Python MtGox auth example
Post by: Ente on January 31, 2012, 02:12:38 PM
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!

https://github.com/rokj/bitcoin_dealer/blob/master/exchange/exchange/mtgox.py (https://github.com/rokj/bitcoin_dealer/blob/master/exchange/exchange/mtgox.py)

Here it is how I am doing, but it supports older API.

Will implement support for newer API in few days.

UPDATE: Here is for APIv1 https://github.com/rokj/bitcoin_dealer/blob/master/exchange/exchange/mtgox1.py (https://github.com/rokj/bitcoin_dealer/blob/master/exchange/exchange/mtgox1.py)

Following seems to work.

Code:
params = [(u"nonce", self._create_nonce())]
headers = {'Rest-Key': key, 'Rest-Sign': base64.b64encode(str(hmac.new(base64.b64decode(secret), urllib.urlencode(params), hashlib.sha512).digest())), 'Content-type': 'application/x-www-form-urlencoded', 'Accept': 'application/json, text/javascript, */*; q=0.01', 'User-Agent': 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'}
http_pool = urllib3.connection_from_url(url)
response = http_pool.urlopen('POST', url, body=urllib.urlencode(params), headers=headers)

print response.status, response.data

For some reason I could not get it working with MtGox APIv1 with other than with urllib3:

A newbie wanted to post this
https://bitcointalk.org/index.php?topic=74530.0

I found this thread (http://'https://bitcointalk.org/index.php?topic=49789.20') to be extremely helpful, so I'm returning the favor by posting an improved and simplified version of the code. Unfortunately, my forum account is limited to the Newbie section. Mods, please move this post to the thread above.
Code:
from hashlib import sha512
from hmac import HMAC
from base64 import b64decode, b64encode
from urllib import urlencode

from time import time

import requests

class MTGox:
def __init__(self, key, secret, base):
self.key = key
self.secret = b64decode(secret)
self.base = base

def query(self, path, args={}):
args['nonce'] = int(time()*100000)
headers = {
'User-Agent': 'BitcoinTalk',
'Rest-Key': self.key,
'Rest-Sign': b64encode(str(HMAC(self.secret, urlencode(args), sha512).digest()))
}
r = requests.post(self.base + path, data=args, headers=headers)
print r.text

As much as I like python, but one has to admit that languages that use static typing do have certain advantages.
A simple if check or catch TypeError would be all that is needed to make a nice error message.  Static typing isn't needed for that.  And also, Adding Optional Static Typing to Python (http://www.artima.com/weblogs/viewpost.jsp?thread=87182)

Also, cython does allow setting types.

some newbie questions:

a) Why there is an API 0 and API 1. Will API 0 soon be deprecated?

b) Is there a bug in the getTrades-Function? The parameter "since" seems to be ignored... Or is there an error in the code of Takkun?

Thank you

Thanks for the code.

However, when I try it, I always get the not logon error like below:
Code:
{u'error': u'Must be logged in'}

The code is like below:
Code:
from urllib import urlencode
import urllib2

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"] = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)"
        headers["Accept"] = "application/json"
        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)


m = requester(auth_key=mykey, auth_secret = mysecret)
print m.perform("info.php", {})

The wired thing is, when I using the C# code to communicate, it all works well.
I checked the http headers and found there're a little difference:

.NET header
Code:
CONNECT mtgox.com:443 HTTP/1.1

Any help is appreciate!

Thanks for the code.

However, when I try it, I always get the not logon error like below:
Code:
{u'error': u'Must be logged in'}

The code is like below:
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"] = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)"
        headers["Accept"] = "application/json"
        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)


m = requester(auth_key=mykey, auth_secret = mysecret)
print m.perform("info.php", {})

The wired thing is, when I using the C# code to communicate, it all works well.
I checked the http headers and found there're a little difference:

.NET header

Had "similar" problems.

First, use APIv1 and for some reason I got it working only with urllib3. See: https://bitcointalk.org/index.php?topic=49789.msg762709#msg762709 (https://bitcointalk.org/index.php?topic=49789.msg762709#msg762709).

I just tried it. However, the result is same:  ???
Code:
import urllib, time, hashlib, hmac, base64, urllib3

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

url = "https://mtgox.com/api/0/info.php"
params = [(u"nonce", _create_nonce())]
headers = {'Rest-Key': key, 'Rest-Sign': base64.b64encode(str(hmac.new(base64.b64decode(secret), urllib.urlencode(params), hashlib.sha512).digest())), 'Content-type': 'application/x-www-form-urlencoded', 'Accept': 'application/json, text/javascript, */*; q=0.01', 'User-Agent': 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'}
http_pool = urllib3.connection_from_url(url)
response = http_pool.urlopen('POST', url, body=urllib.urlencode(params), headers=headers)

print response.status, response.data

200 {"error":"Must be logged in"}

May be because I'm under in proxy, but why .NET code work well? It's all in same machine...

Try APIv1.

https://mtgox.com/api/1/BTCUSD/public/ticker using GET or https://mtgox.com/api/1/generic/private/orders using POST.

Dose the code work on you side? If so, I may need start investigate my network problem instead of code...

I got this "403 {"result":"error","error":"Identification required to access private API","token":"login_required"}" when try https://mtgox.com/api/1/generic/private/orders using POST.

Thanks very much!

Yes, I am using https://github.com/rokj/bitcoin_dealer/ (https://github.com/rokj/bitcoin_dealer/), you probably copied wrong key or missed something out.

Thanks for your help. Your code is working and I finally find out the reason :)

My .NET code generate nonce like this:
Code:
string parameters = "nonce=" + DateTime.Now.Ticks.ToString();
it'll generate a 18 length value like 634705522019762907

In Python code, it generate nonce like this:
Code:
string parameters = "nonce=" + DateTime.Now.Ticks.ToString();
which will generate 16 length value like 133492738213800

In like case, as it always smaller than the last .NET nonce in one account, then MtGox regards it as invalid and can't get authorization.

I simply added more zero to "int(time.time()*1000000000)" and it then works.
(or If I using one account for Python only, then it have no such problem also.)

Again, thanks for your code :)

No problem!  ;)

Argh ... and totally forgot to write this frustration with nonce also (have had same problems when doing it in PHP and then in Python).

Bold your message or something, I am sure someone else will also have the same experience in the future.  :)
