我尝试用Python编码HMAC-SHA256消息根据[指令][1]
import hmac
import hashlib
nonce = 1234
customer_id = 123232
api_key = 2342342348273482374343434
API_SECRET = 892374928347928347283473
message = nonce + customer_id + api_key
signature = hmac.new(
API_SECRET,
msg=message,
digestmod=hashlib.sha256
).hexdigest().upper()
但是我得到了这个
Traceback(最近一次调用):文件"gen.py",第13行,indigestmod = hashlib。sha256 File "/usr/lib/python2.7/hmac.py",第136行,in new文件"/usr/lib/python2.7/HMAC .py",第71行,在init如果len(key)>blocksize: TypeError: 'long'类型的对象没有len()
有人知道为什么崩溃吗?[1]: https://www.bitstamp.net/api/帐户余额
如果你想在python3中执行,你应该这样做:
#python 3
import hmac
import hashlib
nonce = 1
customer_id = 123456
API_SECRET = 'thekey'
api_key = 'thapikey'
message = '{} {} {}'.format(nonce, customer_id, api_key)
signature = hmac.new(
bytes(API_SECRET, 'latin-1'),
msg=bytes(message, 'latin-1'),
digestmod=hashlib.sha256
).hexdigest().upper()
print(signature)
你正在使用数字,而api期望的是字符串/字节。
# python 2
import hmac
import hashlib
nonce = 1234
customer_id = 123232
api_key = 2342342348273482374343434
API_SECRET = 892374928347928347283473
message = '{} {} {}'.format(nonce, customer_id, api_key)
signature = hmac.new(
str(API_SECRET),
msg=message,
digestmod=hashlib.sha256
).hexdigest().upper()
print signature
