Question

我使用Power BI准备了一个科学计量仪表板，该仪表板通过调用API密钥直接连接到Scopus数据库。在我的Power Bi桌面上，它可以刷新数据而没有任何错误，但是在将仪表板发布到Power Bi网站后，无法刷新它并返回凭证错误：

上次刷新失败：2019年11月27日星期三12:32:39 GMT + 0330（伊朗标准时间）处理数据集中的数据时出错。详细信息：为Web源提供的凭据是无效。（来源为https://api.elsevier.com/content/search/scopus。）表：API-Scopus-All。簇 URI：WABI-EAST-ASIA-A-PRIMARY-redirect.analysis.windows.net活动 ID：7edc8fb9-5513-465d-a35b-70cc5629d0d0请求 ID：2edb255e-20fe-d1db-6b7d-2cf1b6681fc5时间：2019-11-27 09：02：39Z

以下代码是我在Power BI中的查询。此外，我在台式机上的凭据是“基本”，其中“用户名” =我的apikey

我只从代码中删除了我的apikey。任何想要重现结果的人，都应该用APIKEY替换他/她的Scopus apikey。此外，应提供对Scopus数据库的访问。

我非常感谢您为解决证书问题提供的帮助。谢谢

该问题可能与以下事实有关：默认情况下，Scopus API使用客户端的IP地址检查其是否已订阅Scopus。在Power BI桌面客户端上运行仪表板时，对Scopus API的请求是从客户端的IP地址发送的，并且如果将您的客户端IP地址设置为可访问Scopus，则您将通过API获得对Scopus数据的完全访问权限也一样但是，当您在Power BI网站上运行仪表板时，对Scopus API的请求可能是从Power BI服务器的IP地址发送的，该IP地址可能没有设置用于访问Scopus。根据您的用例，您可以联系Scopus API支持来请求使用身份验证令牌。
