将图片文件转换为 Base64 编码。 代码示例 下面是一个简单的 Python 示例,演示了如何实现这一过程。 importbase64fromPILimportImagefromioimportBytesIOdefimage_to_base64(image_path):# 使用Pillow打开图片withImage.open(image_path)asimg:buffered=BytesIO()img.save(buffered,format="JPEG")# 可以根据需要改...

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?
