python post 使用 PIL 图片请求

Question

<PIL.WebPImagePlugin.WebPImageFile image mode=RGB size=1600x1600 at 0x1F4E779BA00>这是文件类型当我执行 post 请求时，我收到此错误 TypeError: a bytes-like object is required, not 'WebPImageFile' 。如何将其转换为类似字节的对象？

Answer 1

通过将其保存为某种文件格式。你不能只是通过电线推送抽象像素:)

此示例假定远程端可以接受 PNG 文件。

import io

image = ...  # However you get your image
bio = io.BinaryIO()  # `BinaryIO` is essentially a file in memory
image.save(bio, format="PNG")  # Since there is no filename,
                               # you need to be explicit about the format
bio.seek(0)  # rewind the file we wrote into
requests.post(..., files={'file': bio})

要将文件名也发送到 API，您需要将文件指定为元组。

requests.post(..., files={'file': ('image.png', bio)})
