404从Microsoft Graph下载OneDrive内容

我试图通过microsoft api下载onedrive项目的内容 . 但是，无论我使用哪种方法，我都会收到404回复 . 这是python / requests中问题的再现

import requests
import json

root_url = "https://graph.microsoft.com"
base_path = "/v1.0/<tenant_id>/users/<principal_name>/drive/"

token = "ALONGTOKEN"

headers = {"Authorization": "Bearer %s" % token}

r = requests.get(root_url + base_path + "/root/children", headers=headers)
listing = json.loads(r.text)
target = listing["value"][0]
print("Target node:")
print(json.dumps(target))
print("Target node id:")
print(target["id"])

r = requests.get(root_url + base_path + "items/" + target["id"], headers=headers)
print("Target metadata:")
print(r.text)

resp = json.loads(r.text)
download_url = resp["@microsoft.graph.downloadUrl"]
print("Target download url:")
print(download_url)

r = requests.get(download_url, headers=headers)
print("Download response code:")
print(r.status_code)
print("Download response headers:")
print(r.headers)
print("Download response cookies:")
print(r.cookies)
print("Download response redirect history:")
print(r.history)

输出以下内容：

也就是说，在链接结果后立即产生404，尽管它应该下载文件字节 . 我已经在java，python，bash / curl和浏览器中重现了这个 . 任何人都可以帮助指出我做错了什么，或者这是微软图api的问题？

编辑：

我还可以使用here描述的/ drive / items / / content endpoints 重现相同的404 . 对此 endpoints 的请求会导致302重定向（如文档中所述），如果遵循该重定向，则会产生与上述相同的404行为 .

EDIT2：

以下是我可以在响应头中找到的所有请求ID，这些请求对Microsoft的调试很有用 .

对于项目对象的200请求：'request-id'：'adfa3492-4825-439d-8e59-022f32e78244'，'client-request-id'：'adfa3492-4825-439d-8e59-022f32e78244'

对于下载URL上的404请求：'request-id'：'33e09e9d-b0c2-2000-133c-304585c15000'，'SPRequestGuid'：'33e09e9d-b0c2-2000-133c-304585c15000'，

此外，从404返回的实际HTML包括相关ID：a8e09e9d-a0bb-2000-133b-ef6fc8ac7015
