如何从 HID omnikey 获取智能卡的 TAR答案

【问题标题】：How to get ATR of a smard card from HID omnilkey如何从 HID omnikey 获取智能卡的 TAR
【发布时间】：2014-12-31 07:19:05
【问题描述】：

我想获取智能卡的 ATR。我正在使用 HID omnikey 5321。我正在关注此链接“http://pyscard.sourceforge.net/user-guide.html#requesting-any-card”

到目前为止我已经尝试过：

>>>from smartcard.CardType import AnyCardType
>>>from smartcard.CardRequest import CardRequest
>>>from smartcard.util import toHexString
>>>
>>> cardtype = AnyCardType()
>>> cardrequest = CardRequest( timeout=1, cardType=cardtype )
>>> cardservice = cardrequest.waitforcard() 
>>>
>>>>>> cardservice.connection.connect()

我遇到了错误

cardservice.connection.connect()

类似的错误：

raise CardConnectionException('Unable to connect with ptotocol[pcscprotocol] + . '+ScardGetErrorMessage(hresult) 
CardConnectionException: Unable to conenct the card with T0 or T1 . Card is not responding to reset.

【问题讨论】：

你的卡是非接触式的吗？

【解决方案1】：

在python中，您可以使用pyscard库与智能卡进行交互，有一个示例可以帮助您在http://pyscard.sourceforge.net/pyscard-framework.html#framework-samples显示ATR

【讨论】：

在上面的链接中提到了javascript。怎么办呢
我想从python而不是从网页中获取它，并且所有卡都有ATR吗？为什么因为我在访问卡的 atr 时什么都没有，所以我得到了一个空列表

【解决方案2】：

因为您没有指定要连接的阅读器：

r=readers()
#r[Number of reader list].
cardservice.connection = r[0].createConnection()
cardservice.connection.connect()

一个简单的例子：

from __future__ import print_function
from smartcard.Exceptions import NoCardException
from smartcard.System import readers
from smartcard.util import toHexString

for reader in readers():
    try:
         connection = reader.createConnection()
         connection.connect()
         print(reader, toHexString(connection.getATR()))
    except NoCardException:
         print(reader, 'no card inserted')

import sys
if 'win32' == sys.platform:
    print('press Enter to continue')
    sys.stdin.read(1)

-另一个选择阅读器：

from __future__ import print_function
from smartcard.Exceptions import NoCardException
from smartcard.System import readers
from smartcard.util import toHexString
from smartcard.CardType import AnyCardType
from smartcard.CardRequest import CardRequest

cardtype = AnyCardType()
r=readers()
cardrequest = CardRequest( timeout=10, cardType=cardtype )
cardservice = cardrequest.waitforcard()
print('Available Readers:')
for i in range(len(readers())):
    print('[',i+1,']',r[i])
if(len(readers()) < 1):
    print("\nNO AVAILABLE READERS!\n")
else:
    print("Select you Reader: (Ctrl+C to Exit)")
    my_input = input()
    selectReader = clamp(int(my_input)-1,0,len(readers()))
    print('Selected: ',r[selectReader])
    cardservice.connection = r[selectReader].createConnection()
    cardservice.connection.connect()
    try:
        print('Card ATR:',toHexString(cardservice.connection.getATR()),file=f)
    except:
        print("Cant not Get ATR")
