Javascript 下载带有tempauth的Url在Microsoft graph中抛出403错误

我一直在努力创建一个filehandler来在sharepoint中打开文件。我已经实现了Oauth来授权应用程序

到目前为止，我可以访问文件对象，如下所示：

但是，使用

@microsoft.graph.downloadUrl

任何帮助都将不胜感激。谢谢

更新 我正在使用express调用api。下面的请求返回如上所示的文件对象响应

if(requestBody.items) {
    let [driveItem] = JSON.parse(requestBody.items);
    try {
      let content = await request.get(`${driveItem}`, {
        headers: {
          Authorization: `Bearer ${token}`,
        },
      });
      res.render('test', {content: content});
    } catch(e) {
      res.render('test', {content: e.message});
    }
  }

但在请求内容时，它抛出403

let fileobject = JSON.parse(content);
let file = await request.get(`${fileobject["@microsoft.graph.downloadUrl"]}`)

我还尝试直接向url添加内容，但效果不太好

if(requestBody.items) {
  let [driveItem] = JSON.parse(requestBody.items);
  try {
    let content = await request.get(`${driveItem}/content`, {
      headers: {
        Authorization: `Bearer ${token}`,
      },
    });
    res.render('test', {content: content});
  } catch(e) {
    res.render('test', {content: e.message});
  }

}

我使用这些方法来获取访问令牌

async function getAccessToken(code, callback) {
  let jsonAuth = await request.post({
    url: 'https://login.microsoftonline.com/common/oauth2/token',
    formData: {
      'grant_type' : 'authorization_code',
      'code' : code,
      'client_id' : config.clientId,
      'client_secret' : config.clientSecret,
      'redirect_uri' : 'https://simpliapp.herokuapp.com/'
    }
  });
  callback(jsonAuth);
}

function getAuthorizationCode(res) {
  res.writeHead(302, {
    'Location': `https://login.microsoftonline.com/common/oauth2/authorize?response_type=code&client_id=${config.clientId}&resource=${encodeURIComponent('https://graph.microsoft.com/')}&redirect_uri=${encodeURIComponent('https://simpliapp.herokuapp.com/')}`
  });
  res.end();
}

您是如何请求内容的？一些显示如何调用API的代码会很有帮助。您好，@marclafler我已经更新了这个问题。

/content

端点应该是

DriveItem

请求的一部分。这将返回指向预验证URI的

302

。因此，首先调用

/me/drive/items/{item id}/content

，然后按照该调用返回的

302

检索实际文件。
