python3.x获取显示网络图片

普通图片

bytes_io = BytesIO()
bytes_io.write(r.content)  # 写入bytes，把它当作文件读取
img.show()

base64图片

data = json.loads(r.content).get("obj")
url = data.get("image")
# 在线获取图片对象
image_data = base64.b64decode(url)  # 获取解码后的bytes
bytes_io = BytesIO()
bytes_io.write(image_data)  # 写入bytes，把它当作文件读取
img = Image.open(bytes_io)  # 读取'图片'文件
img.show()

图片类型转换 cv2 - base64 - PIL
