python – 无法转换为HEX – TypeError：找到非十六进制数字

行devicetoken = devicetoken.replace(”,”).decode(‘hex’)正在崩溃我的脚本.
这是设备令牌:(更改了一些数字)

devicetoken =’9cdcb815 d93e11ce 52baaf6c 14e27cc8 31d5ce62 2e51ce6d f75692c2 3617cadb’

第一个推送通知发送正常,所以我确定设备令牌是好的,但在第一个事件后,我收到此错误：

['"INBox" (UNSEEN 12)']

解决方法

您的设备令牌可能不是您认为的那样.也许它有换行或其他一些你看不到的角色.

作为一个简单的测试：

>>> devicetoken = '9cdcb815 d93e11ce 52baaf6c 14e27cc8 31d5ce62 2e51ce6d f75692c2 3617cadb'
>>> devicetoken.replace(' ','')
'9cdcb815d93e11ce52baaf6c14e27cc831d5ce622e51ce6df75692c23617cadb'
>>> devicetoken.replace(' ','').decode('hex')
'\x9c\xdc\xb8\x15\xd9>\x11\xceR\xba\xafl\x14\xe2|\xc81\xd5\xceb.Q\xcem\xf7V\x92\xc26\x17\xca\xdb'
