Question

ciphertext = base64.b64decode(xxxxxx) //output is b'148,240,50,66,81,26,240,2,101,31'
bytearray(ciphertext) // output is bytearray(b'148,240,50,66,81,26,240,2,101,31')

我要找的是 bytearray([148,240,50,66,81,26,240,2,101,31]) 的 output

完整代碼：

Answer 1

代替：

bytearray(ciphertext)

和：

bytearray(map(int, ciphertext.split(b',')))
# Or if you prefer genexprs:
bytearray(int(x) for x in ciphertext.split(b','))

前者只是將原始bytes轉換為等效的bytearray ，后者用逗號將其拆分並將組件解析為int s。
