Hi,
I'm recently write a small program to trade bitcoin in MtGox, but I met a wierd problem when using Python to communicate with MtGox API.
The code is from post "Python MtGox auth example", however, I'm always get the not logon error like below:
{u'error': u'Must be logged in'}The code is like below:
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:

I guess it may related with the
connection type, but I'm new to Python and have no idea how to control it...
(why there're dozens of http lib exist in Python :)
Any help is appreciate!
