Question

我正在尝试通过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：

这就是说，紧接着链接后会产生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：

我还可以使用描述为here的/ drive / items / {item-id} / content端点重现相同的404。对此端点的请求会导致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：

以下是我在响应头中可以找到的所有请求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'< / p>

对于下载网址上的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

Answer 1

文件下载目前仅受委派权限（例如File.Read范围）支持，如文档here所示。您的请求是使用应用程序权限Files.Read.All和Files.ReadWrite.All进行的，我们正在逐步添加支持，但它们尚未完全正常运行且不是列出here。

Answer 2

你能检查item_id实际上是一个项目的ID吗？如果你正在处理GET /v1.0/users//drive/items/返回的集合，该集合将返回一个文件夹和项元数据的数组。如果您针对某个文件夹尝试了请求，则会按照您的描述获得404。这是我可以重复你的问题的唯一方法。如果这不是问题，请提供请求/响应跟踪，以便我们可以看到错误详细信息。
