【问题描述】:
我正在尝试使用引导程序为我的项目设置样式,但我不断收到 CORS 策略错误。我的网站只显示没有样式的库存 HTML。单击“添加到表格”按钮不会打开模式。也不知道为什么会加载样式。

</html>
这是错误。
从源“http://localhost:63341”访问“https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css”处的 CSS 样式表已被 CORS 策略阻止:对预检请求的响应未通过访问控制检查:它没有 HTTP ok 状态。 index.html:7GET https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css net::ERR_FAILED
关于如何解决这个问题的任何想法?
谢谢
