Python：转换在字节数组中编码十六进制的json字符串(Python: Convert a json string that encodes an hexadecimal in an array of bytes)

我有一个数据=“90ab”的json

unpack = json.loads(content) data = unpack['data'] data_byte=bytearray.fromhex(data)

我希望data_byte是一个字节数组[byte1 byte2]，byte1 = 0x90，而byte2 = 0xab我需要帮助，因为我试过的似乎不起作用谢谢

I have a json with data="90ab"

unpack = json.loads(content) data = unpack['data'] data_byte=bytearray.fromhex(data)

I want data_byte to be an array of bytes [byte1 byte2], with byte1=0x90, and byte2=0xab I need help, because what I tried doesn't seem to work Thanks

最满意答案

它取决于python版本，因此解码十六进制数据的方式可能会有所不同：

data="90ab"

从Python 2.7和3.0开始：

bytearray.fromhex(data)

Python 2.6及之前版本：

data.decode("hex")

It depends on python version, so the way to decode hex data may vary:

data="90ab"

Since Python 2.7 and 3.0:

bytearray.fromhex(data)

Python 2.6 and before:

data.decode("hex")
