Python request上传图片问题

[musnows]

如题，我尝试了很久，都没有办法能正常通过内存将图片上传到lsky

错误情况

    imgByteArr = io.BytesIO(bg.tobytes())
    imgByteArr.name = './test.png'
    #bg.save(imgByteArr,format='PNG')
    img = io.BufferedReader(imgByteArr)
    url = "http://127.0.0.1:14700/api/v1/upload"
    header = {
        "Authorization": "Bearer TOKEN",
        "Accept": "application/json"
    }
    params = {'strategy_id':3}
    myfiles = {'file': img}
    return requests.post(url, headers=header, params=params,
                        files=myfiles)  # 请求api

权限是没有问题的，bg的类型是PIL.PngImagePlugin.PngImageFile，不管采用PIL的save方法存到io.BytesIO中，还是用tobytes()传到BytesIO中，都没有办法正确上传图片

 imgByteArr.name = './test.png'

如果不设置名字，就会提示不支持的图片格式；

<Response [200]>
{'status': False, 'message': '不支持的文件类型', 'data': {}}

现在设置了名字后，提示服务异常请稍后再试

<Response [200]>
{'status': False, 'message': '服务异常，请稍后再试', 'data': {}}

目前可行的情况如下：

• 使用open(path,'rb')打开图片作为参数上传；
• 将io.BytesIO的name设置成test.gif，可我的图片是png，以gif上传无法正常读取；

我的需求

虽然我知道可以用PIL的save方法保存到硬盘里面再重新open，但是这样很耗费时间（实测原本直接上传是1s的处理时间，加上保存到磁盘再open打开，就变成了1.8s，几乎于两倍）

而且保存到磁盘还需要进行随机重命名，避免冲突。

我的图片是一个PIL画图的结果，多人请求的时候，若保存到磁盘，需要提供不同的文件名字避免冲突。如果能直接通过内存上传，就相当于节省了保存再打开的时间

需求就是能通过保存到内存中再上传到lsky，求python大佬教一下 ，感激不尽！

查看其他的贴子，知道了如果出现错误会在storage/logs里面打印信息，在此提供logs

这样可以解决了，我先下载图片，保存在内存中，之后调用接口上传图片

import requests
from io import BytesIO, BufferedReader

download_url = '123.jpg'

response = requests.get(download_url)

if response.status_code == 200:
    # 创建 BytesIO 对象并将文件内容写入其中
    file_in_memory_bytes = BytesIO(response.content)
    file_in_memory_bytes.name = '123.jpg'
    file_in_memory = BufferedReader(file_in_memory_bytes)

    result = requests.post(
        url=f'{url}/upload',
        headers={
            'Authorization': 'Bearer ',
            'Accept': 'application/json'
        },
        files={'file': file_in_memory}
    )

    print(result.text)
    print(result.json())
