从Microsoft Graph API请求列表项时接收到空数组 [英] Receiving an empty array when requesting list items from Microsoft Graph API

问题描述

我正在尝试使用Microsoft Graph通过JS应用程序上的获取请求来访问SharePoint列表的项目.

I'm trying to use Microsoft Graph to access the items of a SharePoint List with fetch requests on a JS application.

当我发出以下请求时:

export const getList = access_token => {
  const token = "Bearer " + access_token;

  const url = `${apiUrl}/${siteId}/lists/${listId}`;

  return fetch(url, {
    method: "get",
    headers: {
      Authorization: token,
      Accept: "application/json;odata.metadata=none"
    }
  }).then(res => res.json());
};

我得到的是一个有效的JSON响应，其中包含有关所讨论列表的详细信息.

What I get is a valid JSON response with details about the list in question.

但是，当我使用此请求时:

However, when I use this request:

export const getItems = access_token => {
  const url = `${apiUrl}/${siteId}/lists/${listId}/items`;
  const token = "Bearer " + access_token;

  return fetch(url, {
    method: "get",
    headers: {
      Authorization: token,
      Accept: "application/json;odata.metadata=none"
    }
  }).then(res => res.json());
};

我认为应该返回该列表中包含的项目的

，尽管列表不为空，但我得到一个带有空数组的响应.

which I think is supposed to return the items contained in that list, I get a response with an empty array, although the list is not empty.

我可能应该补充一点，我正在使用以下URL来获取访问令牌:

I probably should add that I'm using the following URL to get the access token:

const tokenUrl = `https://login.microsoftonline.com/${siteURL}/oauth2/v2.0/token`

我想念什么吗?

添加发出请求时收到的响应

Adding the responses received when making the requests

使用URL获取列表信息时:

When getting information of a list with the URL:

const url = `${apiUrl}/${siteId}/lists/${listId}`;

响应是以下对象:

{
    createdBy: {user: {…}}
    createdDateTime: "2018-09-13T04:01:11Z"
    description: ""
    displayName: "Pessoa"
    eTag ""70c738b2-d857-4431-a079-bcc0c60efbe4,16""
    id: "70c738b2-d857-4431-a079-bcc0c60efbe4"
    lastModifiedDateTime: "2018-09-13T04:08:47Z"
    list: {contentTypesEnabled: false, hidden: false, template: "genericList"}
    name: "Pessoa"
    parentReference: {}
    webUrl: "https://incubadorahabits.sharepoint.com/sites/PlataformaTecnologica/Lists/Pessoa"
}

尝试获取带有URL的列表项时:

When trying to get the list items with the URL:

const url = `${apiUrl}/${siteId}/lists/${listId}/items`;

响应为:

{
    value: []
}

https://graph.microsoft.com/beta/sites/{site-id}/lists/{list-id}/items endpoint的

推荐答案

Empty 结果通常表示缺少必需的权限. 要查询SharePoint列表项，根据列表类型，需要指定以下权限范围:

Empty results for https://graph.microsoft.com/beta/sites/{site-id}/lists/{list-id}/items endpoint usually means that required permissions are missing. To query SharePoint list items, depending on the list type the following permission scope needs to be specified:

• 对于SharePoint 列表:Sites.Read.All或Sites.ReadWrite.All
• 对于SharePoint 库:Files.Read.All或Files.ReadWrite.All

• for SharePoint List: Sites.Read.All or Sites.ReadWrite.All
• for SharePoint Library: Files.Read.All or Files.ReadWrite.All
