我从 socketio 连接接收到一个 base64 编码的字符串,将其转换为 uint8 并对其进行处理,然后需要将其转换为 base64 字符串以便我可以将其发回。 所以,到目前为止,我已经得到了这个(我正在从 socketio 服务器获取 data 字典): import pickle import base64 from io import BytesIO from PIL import Image base...

compressed += compressor.flush()returnbase64.b64encode(compressed)returnbody 但是python 会抛出此错误消息。 TypeError: abytes-likeobjectisrequired,not'_io.BytesIO' 在这一行: returnzlib.decompress(body) 本质上,我如何从“_io.BytesIO”转换为类似字节的对象?
