python - 为什么在 Rossum API 中上传文档时出现此错误，提示解包值太多（预期为 2）？

Question

因此，我正在尝试使用 python 请求将文档上传到 Rossum 存储，并且我尝试了与https://developers.rossum.ai/docs/python-for-uploading-data-in-rossum-api中完全相同的代码

import requests

username = "username"
password = "password"
queue_id = "123456"
path = "D:/Downloads/INV001.jpg"

url = "https://api.elis.rossum.ai/v1/queues/%s/upload" % queue_id

with open(path, "rb") as f:
    print(f)
    response = requests.post(
    url,
    files={"content", f},
    auth=(username,password),
    )
    #print(response)
annotation_url = response.json()["results"][0]["annotation"]
print("The file is reachable at the following URL:", annotation_url)

当我运行此代码时，我收到如下错误：

ValueError: too many values to unpack (expected 2)

我已经尝试了很多东西，比如

f = {'image': (name_img,img,'multipart/form-data',{'Expires': '0'}) }

和

f = {'image': open(path, 'rb')}

任何想法来解决这个错误。仅供参考，我正在尝试上传 jpg
