我无法将文件选择器共享点与 React 应用程序集成。它没有在弹出窗口中加载文件

Question

我正在尝试按照 Microsoft 指南将共享点与我的应用程序集成。我不明白为什么文件选择器窗口打开但没有显示任何文件。有时会显示 “PrefetchFailure (3001000,invalid_client)”或“初始化在 40000 毫秒后超时”。

const sharePointBaseUrl = 'https://tenant.sharepoint.com';

const openSharepoint = (accessToken, options, baseUrl) => {

let port = null;
const win = window.open('', 'Picker', 'width=1080,height=680');

const queryString = new URLSearchParams({
  filePicker: JSON.stringify(options),
  locale: 'en-us',
});

const accessToken = await getToken(baseUrl);

const url = `${baseUrl}/_layouts/15/FilePicker.aspx?${queryString}`;

const form = win.document.createElement('form');
form.setAttribute('action', url);
form.setAttribute('method', 'POST');
const tokenInput = win.document.createElement('input');

tokenInput.setAttribute('type', 'hidden');
tokenInput.setAttribute('name', 'access_token');
tokenInput.setAttribute('value', accessToken);

form.appendChild(tokenInput);
win.document.body.append(form);
form.submit();

window.addEventListener('message', (event) => {
  if (event.source && event.source === win) {
    const message = event.data;

    if (message.type === 'initialize' && message.channelId === options.messaging.channelId) {
      port = event.ports[0];

      port.addEventListener('message', messageListener);

      port.start();

      port.postMessage({
        type: 'activate',
      });
    }
  }
});
