azure - OneDrive REST API : "message": "The specified item does not have content." when downloading a file

Question

用例

我想使用 REST API 从 OneDrive 下载 Excel 工作表

文档:

建议调用此端点的文档:GET/me/drive/items/{item-id}/content

• https://learn.microsoft.com/en-US/graph/api/driveitem-get-content?view=graph-rest-1.0&tabs=http

先决条件

1. 我使用 oauth2 正确登录，所有其他方法均有效，例如“/me”、“/me/drive/recent”、“/me/drive/sharedWithMe”

2. 授予的凭据

调用GET/me/drive/items/{item-id}/content时出现错误消息

{
  "error": {
    "code": "itemNotFound", 
    "innerError": {
      "client-request-id": "aaaaaaa-aaaa-aaaa-aaaa-aaaaa", 
      "date": "2020-09-26T09:19:08", 
      "request-id": "aaaaa-aaaa-aaaa-aaa-aaa"
    }, 
    "message": "The specified item does not have content."
  }
}

当我调用 GET/me/drive/items/{item-id}

时，该文件存在并包含数据

文件存在且大小:46.272 字节

{
  "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('<a_username>%40hotmail.com')/drive/items/$entity", 
  "createdBy": {
    "user": {
      "displayName": "<a_name> ", 
      "id": "<a_drive_id>"
    }
  }, 
  "createdDateTime": "2020-09-27T07:29:04.893Z",

  }, 
  "id": "<a_drive_id>!<a_sub_id>", 
  "lastModifiedBy": {
    "user": {
      "displayName": "<a_name> ", 
      "id": "<a_drive_id>"
    }
  }, 
  "lastModifiedDateTime": "2020-09-27T18:46:25.073Z", 
  "name": "a_filename.xlsx", 
  "parentReference": {
    "driveId": "<a_drive_id>", 
    "driveType": "personal"
  }, 
  "remoteItem": {
    "file": {}, 
    "fileSystemInfo": {
      "lastAccessedDateTime": "2020-09-27T11:52:31Z"
    }, 
    "id": "<an_id>!7757", 
    "name": "a_filename.xlsx", 
    "parentReference": {
      "driveId": "<an_id>", 
      "driveType": "personal"
    }, 
    "size": 46272, 
    "webUrl": "https://1drv.ms/u/<a_letter>!<a_web_url_id>"
  }, 
  "webUrl": "https://1drv.ms/u/<a_letter>!<a_web_url_id>"
}

结论

微软的API实现有bug吗？!？

我做错了什么？

Answer 1

首先我们需要注意的是，在api文档中，提到了:

Only driveItems with the file property can be downloaded.

因此，当我们调用 https://graph.microsoft.com/v1.0/me/drive/时，我们需要确保目标项在响应中具有属性 file项目/item_id

那么我们需要关注this section ，当我们成功调用下载api时，会返回302重定向
