如何使用 JSON 正确编码包含字节的字典？
回答by Martijn Pieters
The JSON format only supports unicode strings. Since Base64 encodes bytes to ASCII-only bytes, you can use that codec to decode the data:
JSON 格式仅支持unicode 字符串。由于 Base64 将字节编码为纯 ASCII 字节，您可以使用该编解码器来解码数据：
encoded = base64.encodestring(b'data to be encoded')
data['bytes'] = encoded.decode('ascii')
