无法转换为十六进制 - 类型错误：找到非十六进制数字

Question

deviceToken = deviceToken.replace(' ','').decode('hex')行将使我的脚本崩溃。这是设备令牌:(修改了一些数字)

deviceToken = '9cdcb815 d93e11ce 52baaf6c 14e27cc8 31d5ce62 2e51ce6d f75692c2 3617cadb'

第一个推送通知发送良好，所以我确定设备令牌是ok的，但在第一个事件之后，我得到这个错误:

['"INBOX" (UNSEEN 12)'] 
Sent Push alert.

['"INBOX" (UNSEEN 13)']

您的设备令牌可能不是您所想的那样。也许它有一个换行符或其他一些你看不到的字符。

作为简单的测试:

>>> deviceToken = '9cdcb815 d93e11ce 52baaf6c 14e27cc8 31d5ce62 2e51ce6d f75692c2 3617cadb'
>>> deviceToken.replace(' ','')
'9cdcb815d93e11ce52baaf6c14e27cc831d5ce622e51ce6df75692c23617cadb'
>>> deviceToken.replace(' ','').decode('hex')
'x9cxdcxb8x15xd9>x11xceRxbaxaflx14xe2|xc81xd5xceb.Qxcemxf7Vx92xc26x17xcaxdb'
