使用 Api Rest 的 Sharepoint 列表项

Question

我需要获取列表的项目，所以我创建了这个函数

export function retrieveSPItems(spToken, alias) {
  var url = `{path_to_my_site}/_api/web/Lists/getByTitle('Briefs')/ItemCount`;
  var myHeaders = new Headers({
    Accept: "application/json;odata=nometadata",
    Authorization: spToken,
  });
  return fetch(url, {
    method: "get",
    headers: myHeaders,
  }).then((response) => response.json());
}

作为输出，我得到 3000。

当我将网址更改为

var url = `{path_to_my_site}/_api/web/Lists/getByTitle('Briefs')/Items`;

我得到一个空列表！

PS：

在 Postman 中可以正常工作

token 由 adaljs 生成：

获取令牌

authContext.acquireToken(SP_BASE_URL, function (error, token){....})

Adal 配置

export const adalConfig = {
  tenant: CURRENT_TENANT,
  clientId: CURRENT_APP_ID,
  endpoints: {
    api: CURRENT_APP_ID,
    graph: GRAPH_BASE_URL,
    sharepoint: SP_BASE_URL,
  },
  cacheLocation: "localStorage",
  validateAuthority: true,
};

所以我需要知道：

• 出现此问题的原因是什么？

• 我该如何解决？

信息太笼统，需要debug搞清楚详细的错误信息。

我的测试演示：

<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <script src="Scripts/adal.js"></script>
